What do different poop colors indicate. How can diet affect stool color. When should you be concerned about changes in bowel movement color. What health issues can cause abnormal stool colors.

The Rainbow of Stool Colors: Understanding What They Mean

The color of your stool can provide valuable insights into your overall health and digestive function. While variations in poop color are often harmless and related to diet, certain hues may signal underlying health issues that require attention. This comprehensive guide explores the spectrum of stool colors, their potential causes, and when you should consult a healthcare professional.

Brown: The Standard Shade of Healthy Stool

Brown is the most common and typically healthiest color for stool. But why is poop usually brown? The answer lies in bile, a digestive fluid produced by the liver. Bile starts as a yellowish-green liquid, but as it travels through the digestive system, it undergoes chemical changes that result in the familiar brown color of feces.

The shade of brown can vary slightly from person to person and even from day to day, depending on diet and other factors. As long as your stool remains within the brown spectrum and maintains a consistent texture, there’s usually no cause for concern.

Green Poop: Common Causes and When to Worry

Seeing green stool in the toilet bowl can be surprising, but it’s often harmless. What causes green poop? There are several potential reasons:

• Consumption of green vegetables like spinach or kale
• Ingestion of food coloring, such as in drinks or desserts
• Use of iron supplements
• Rapid intestinal transit time, which doesn’t allow bile to break down completely

In most cases, green stool is not a cause for concern. However, if it persists for an extended period or is accompanied by other symptoms like abdominal pain or diarrhea, it’s advisable to consult a healthcare provider.

Green Diarrhea: A Potential Sign of Digestive Issues

When green stool is accompanied by diarrhea, it may indicate that food is moving through the digestive tract too quickly. This rapid transit doesn’t allow enough time for bile to break down completely, resulting in the green color. While occasional green diarrhea is usually not serious, persistent cases may warrant medical attention.

Yellow Stool: Potential Indicators of Digestive Problems

Yellow poop can range from a pale, clay-like color to a more vibrant yellow hue. While yellow stool is normal for many people, especially breastfed infants, certain characteristics may indicate underlying health issues.

Is yellow poop always a cause for concern? Not necessarily, but pay attention to these factors:

• Greasy appearance
• Foul odor
• Persistent yellow color

If your stool exhibits these characteristics, it may contain excess fat, suggesting potential problems with fat digestion or absorption. This could be related to conditions such as celiac disease, where the body can’t properly process gluten.

Celiac Disease and Yellow Stool

For individuals with celiac disease, consuming gluten-containing foods can lead to intestinal damage and malabsorption. This may result in fatty, yellow stools. If you suspect celiac disease might be the cause of your yellow poop, it’s crucial to consult a healthcare provider for proper diagnosis and treatment.

White, Pale, or Clay-Colored Stool: Potential Bile Duct Issues

Pale or clay-colored stools can be alarming, as they often indicate a lack of bile in the stool. This absence of bile pigment may point to problems in bile production or flow. What causes white or pale stool? Several factors can contribute:

• Certain medications, such as bismuth subsalicylate (Pepto-Bismol)
• Barium sulfate, used in some diagnostic imaging procedures
• Liver diseases like hepatitis
• Blockages in the bile ducts

Persistent pale or clay-colored stools warrant immediate medical attention, as they may indicate serious liver or gallbladder issues.

Gallstones and Bile Duct Obstruction

Gallstones or tumors can obstruct the bile ducts, preventing bile from reaching the intestines. This blockage not only affects stool color but can also lead to other symptoms such as abdominal pain, jaundice, and dark urine. If you experience these symptoms along with pale stools, seek medical care promptly.

Black Stool: Harmless Causes and Potential Red Flags

Black stool, also known as melena, can be alarming but isn’t always a sign of a serious problem. What causes black poop? There are both benign and concerning reasons:

Harmless Causes of Black Stool

• Consuming black licorice
• Eating large quantities of blueberries
• Taking iron supplements
• Using medications containing bismuth subsalicylate

Potential Serious Causes of Black Stool

When black stool has a tarry appearance and foul odor, it may indicate bleeding in the upper gastrointestinal tract. Possible causes include:

• Stomach ulcers
• Esophageal bleeding from severe acid reflux
• Noncancerous tumors in the upper GI tract
• Gastrointestinal cancers

If you experience black, tarry stools that cannot be explained by diet or medication, seek immediate medical attention.

Red or Reddish Stool: Dietary Influences and Health Concerns

Seeing red in the toilet bowl can be alarming, but it’s not always a sign of a serious problem. What causes red poop? There are several potential reasons:

Dietary Causes of Red Stool

• Consuming beets or foods with red food coloring
• Eating tomato-based products
• Drinking red-colored beverages
• Ingesting red gelatin desserts

In many cases, red stool is simply the result of what you’ve eaten and will resolve on its own within a day or two.

Medical Causes of Red Stool

However, if the red color persists or is accompanied by other symptoms, it may indicate bleeding in the lower gastrointestinal tract. Potential causes include:

• Hemorrhoids
• Anal fissures
• Inflammatory bowel diseases like Crohn’s disease or ulcerative colitis
• Colorectal polyps or cancer

If you experience persistent red stools not explained by diet, or if you notice blood in your stool, consult a healthcare provider promptly.

Orange Stool: Dietary Influences and Potential Health Implications

Orange-colored stool is less common than other hues but can occur due to various factors. What causes orange poop? Let’s explore the potential reasons:

Dietary Causes of Orange Stool

• Consuming large amounts of orange-colored foods like carrots or sweet potatoes
• Eating foods with beta-carotene supplements
• Ingesting certain medications or supplements with orange dyes

In most cases, orange stool resulting from dietary factors is harmless and will return to a normal color once the responsible food is no longer being consumed in large quantities.

Potential Health-Related Causes of Orange Stool

While less common, orange stool can sometimes indicate underlying health issues:

• Bile duct obstruction: If bile isn’t being released properly into the intestines, it can result in lighter-colored stools, sometimes appearing orange.
• Certain digestive disorders: Conditions that affect fat absorption, such as celiac disease or short bowel syndrome, can sometimes lead to orange-tinged stools.
• Liver problems: In rare cases, orange stools may be associated with liver dysfunction.

If orange stools persist without an obvious dietary cause or are accompanied by other symptoms like abdominal pain or weight loss, it’s advisable to consult a healthcare provider.

When to Seek Medical Attention for Stool Color Changes

While many stool color changes are harmless and temporary, certain situations warrant medical attention. When should you be concerned about poop color? Consider seeking medical help if:

• You experience persistent changes in stool color that last more than a few days
• Your stools are black and tarry, or bright red
• You have pale or clay-colored stools accompanied by dark urine or jaundice
• Stool color changes are accompanied by other symptoms such as abdominal pain, fever, or unexplained weight loss
• You notice blood in your stool, regardless of its color

Remember, your stool can provide valuable insights into your digestive health. While occasional color changes are often benign, persistent or concerning changes should never be ignored. By staying aware of what’s normal for you and promptly addressing any unusual changes, you can take proactive steps to maintain your digestive health and overall well-being.

The Role of Diet in Stool Color Variations

Diet plays a significant role in determining stool color. How does what you eat affect your poop color? Let’s explore some common dietary influences:

Foods That Can Alter Stool Color

• Green vegetables: Spinach, kale, and other leafy greens can lead to green stools
• Beets: Can cause red or reddish-purple stools
• Blueberries: May result in dark blue or black stools
• Carrots and sweet potatoes: Can lead to orange-tinged stools
• Licorice: Black licorice can cause dark black stools

Understanding these dietary influences can help you better interpret changes in your stool color and avoid unnecessary worry. However, it’s important to note that persistent color changes, even those potentially related to diet, should be monitored and discussed with a healthcare provider if they continue for an extended period.

The Impact of Food Dyes on Stool Color

Artificial food colorings can have a significant impact on stool color. These dyes are often found in:

• Colored beverages
• Popsicles and ice creams
• Candies and other sweets
• Some breakfast cereals

The effect of food dyes on stool color is usually temporary and harmless. However, if you’re concerned about frequent color changes in your stool, consider keeping a food diary to track potential correlations between your diet and stool appearance.

Understanding the Link Between Digestive Health and Stool Color

The color of your stool can provide valuable insights into your digestive health. How does the digestive process influence stool color? Let’s break it down:

The Role of Bile in Stool Color

Bile, produced by the liver and stored in the gallbladder, plays a crucial role in determining stool color. This greenish-yellow fluid helps break down fats and carries waste products from the liver. As bile travels through the digestive system, it undergoes chemical changes that result in the brown color of normal stools.

When bile production or flow is impaired, it can lead to changes in stool color. For example:

• Pale or clay-colored stools may indicate a lack of bile reaching the intestines
• Very dark stools could suggest an excess of bile pigments

Transit Time and Stool Color

The speed at which food moves through your digestive system can also affect stool color. Rapid transit time, often associated with diarrhea, may result in green stools because bile doesn’t have time to break down completely. Conversely, slow transit time can lead to darker stools as more water is absorbed in the intestines.

Understanding these digestive processes can help you better interpret changes in your stool color and recognize when these changes might indicate a potential health concern.

The Importance of Regular Stool Monitoring

While it may seem unpleasant, paying attention to your stool can provide valuable information about your health. Why is it important to monitor your stool regularly?

• Early detection of potential health issues
• Insight into your digestive function
• Indication of dietary imbalances or intolerances
• Tracking of overall health and wellness

Regular monitoring doesn’t mean obsessing over every bowel movement, but rather being aware of what’s normal for you and noting any persistent changes. If you notice consistent alterations in your stool color, consistency, or frequency, it’s worth discussing these changes with a healthcare provider.

Tools for Tracking Stool Health

Several tools can assist in monitoring stool health:

• Bristol Stool Chart: This medical aid classifies stool into seven types based on shape and consistency
• Stool tracking apps: These can help you log and analyze patterns in your bowel movements
• Food and symptom diaries: Useful for identifying correlations between diet and stool changes

By incorporating these tools into your health routine, you can gain a better understanding of your digestive health and more easily identify potential concerns.

What Do Different Poop Colors Mean?

• Normal Poop Color
• Green Poop
• Yellow Poop
• White, Pale, or Clay-Colored Poop
• Black Poop
• Red or Reddish Poop
• Orange Poop
• When to Get Help for Poop Color Changes
• More

Different stool colors can mean different things, mostly depending on what you’ve eaten.

You’d probably notice if your poop is a different hue than normal. But what does it mean if it’s green? What about red, yellow, white, or black? Or orange?

Most of the time, minor changes in the color of your waste are due to diet. After all, we don’t eat the same thing at every meal, every day. But sometimes a color change can signal a minor health issue. In rare cases, it means something serious is wrong in your digestive system.

If the color you see before you flush worries you, call your doctor.

Poop is normally brown. The color is the result of what you eat and how much bile is in your stool.

Bile is a fluid your liver makes to digest fats. It starts out as a yellowish green color. But as the pigments that give bile its color travel through your digestive system, they go through chemical changes and turn brown.

Your poop can sometimes have a slightly greenish hue, or even be a more vivid green. Most of the time, green or greenish poop is normal.

Is your diet causing green poop?

Think back on what you’ve been eating. These foods and supplements can cause your poop to be green:

• Green veggies, like spinach or kale
• Green food coloring, such as in drink mixes or ice pops
• Iron supplements

Other causes of green poop

If you have green diarrhea, the color of your food may not be to blame. It’s likely that your meal moved through your gut too quickly, so the fat-digesting bile didn’t have time to turn brown.

There may be times when your poop looks more yellow than brown.

This shade is also normal for many people. It’s common for babies, especially those who breastfeed. But if you have yellow poop that looks greasy and smells very bad, it may have too much fat. That could be a sign your body isn’t digesting food properly.

Is your diet causing yellow poop?

Indirectly, your diet could cause yellow poop. If you have celiac disease, your body can’t handle a protein called gluten, which is in wheat, barley, and rye. If you have the condition and eat foods that have gluten, like many breads, pastas, and cookies, your intestines won’t work as they should. So, if you’re eating those foods, and your poop is yellow, it may be time to see a doctor.

Other causes of yellow poop

There may be other causes of yellow poop that’s greasy and smelly. If it happens to you often, tell your doctor.

Sometimes, poop may not have much color at all.

Is your diet causing pale poop?

If your poop is pale, it’s not likely directly due to a food. But medicines for diarrhea like bismuth subsalicylate (Kaopectate, Pepto-Bismol) can sometimes cause pale or clay-colored poop. So can barium, a chalky liquid you drink before you get X-rays of the upper part of your digestive tract.

Other causes of pale poop

A more serious cause is a lack of bile in your stool. (Remember, bile gives poop its brown color.) Your body makes bile in the liver, stores it in the gallbladder, and releases it into your small intestine to help digest your food. If there’s not enough of it to give your poop its typical brown color, it could be a sign of a problem along the way.

Liver disease, such as hepatitis, can keep bile from getting into your body waste. So can a blockage in the tubes (called ducts) that carry bile. This can happen because of:

• Gallstones
• A tumor
• A condition you’re born with called biliary atresia

Babies’ poop is black for the first few days after they’re born. Otherwise, it may be because you ate something very dark-colored or took a medicine or supplement that causes black poop. But this color can be a sign of a more serious problem: bleeding in the upper part of your digestive tract.

Is your diet causing black poop?

Foods and supplements that turn poop black include:

• Black licorice
• Blueberries
• Iron supplements

Medicines that have bismuth subsalicylate (Kaopectate, Pepto-Bismol) can also cause very dark stools.

Other causes of black poop

Poop that looks like tar is often a sign of bleeding in the digestive tract. Some causes include:

• Bleeding from stomach ulcers
• Bleeding sores in your esophagus from acid reflux
• Bleeding from noncancerous tumors in the upper GI tract
• Cancer

If you don’t think black poop came from what you ate, you need to talk to your doctor.

If you see red or reddish poop in the toilet, don’t be alarmed right away. First ask yourself if you’ve had red foods lately.

Is your diet causing red or reddish poop?

Several foods can change the color of your stool to a pink or reddish color:

• Beets
• Tomato soup
• Gelatin dessert
• Red drinks

Other causes of red or reddish poop

If you don’t think your diet is the cause, the red you see may be blood. And if it’s bright red, the blood likely comes from the lower part of your digestive tract. Common causes include:

• Noncancerous tumors
• Cancer
• Inflammation in the colon, called colitis
• Growths called polyps in your colon
• Conditions caused by small sacs in the wall of the colon, called diverticular disease
• Hemorrhoids

Call your doctor if you see red that’s probably not from food you ate.

Poop can often come out the color of the food that went in, especially if you have diarrhea. If your poop has an orange hue, it’s most likely due to some orange foods.

Is your diet causing orange poop?

Foods that have beta-carotene can turn your poop orange, such as:

• Carrots
• Winter squash
• Pumpkin
• Sweet potatoes

Foods with orange coloring, such as sodas, candy, or gelatin dessert, can also give your poop an orange color.

Also, antibiotics and antacids that have aluminum hydroxide in them can make your stool orange.

Other causes of orange poop

Rarely, poop can be orange if you have a problem with your liver that causes it to make less bile than normal, or a blockage that keeps bile from leaving the liver and entering your system. But usually, if this is the case, your poop will be pale or clay-colored.

Most of the time, poop that’s a different color from what you’re used to isn’t something to worry about. It’s rare for it to be a sign of a serious condition in your digestive system. But if it’s white, bright red, or black, and you don’t think it’s from something you ate, call your doctor.

Is it possible to determine bowel disease by feces?

During an appointment with a gastroenterologist, many patients avert their eyes to the question: “How long have you been paying attention to the result of the work of the gastrointestinal tract?” It’s not embarrassing!

In our opinion, it is much sadder if you have never looked at your feces. Such observations are a very important method of self-diagnosis and diagnostics in general. It is periodic observation that is dominant, and not one single look at the stool in the morning before a visit to the doctor.

A change in stool parameters is one of the main symptoms of most diseases of the intestines and the gastrointestinal tract in general.

Indicators to pay attention to when self-diagnosing stools :

• frequency per day and per week;
• consistency and volume;
• change in the frequency and consistency of the stool, in comparison with how it was before, when peace and tranquility reigned in the stomach;
• impurities in the stool and its color;
• cases of unsuccessful or excessive urge to empty the bowels;
• lack of urge to defecate or feeling of incomplete emptying of the bowels.

You don’t have to look for a problem where there isn’t one, and you certainly shouldn’t turn a blind eye to alarming symptoms. To determine what is the norm, it is important to understand that each organism is individual!

Normal chair characteristics

1. Frequency – usually 1-2 times a day, 3 to 7 times a week.
2. Stool consistency, for quick orientation of the patient and the doctor in it, the Bristol scale, which was published back in 1997, is used. Let’s get to know her better. Depending on the diet, the amount of fiber, water, stools can normally vary from type 3 to type 5.
3. Stool stability is perhaps the most difficult to explain: there should be no sudden changes in consistency, stool frequency during the week, +/- one type on the Bristol scale. Also important is the subjective sensation before, during and after the act of defecation. Here is a place for satisfaction and quiet joy, I’m quite serious!
4. The color of the stool can be varied, it depends on the diet. Brown of different shades is considered optimal. We make an amendment for the color of food: a lot of dairy products in the diet – the stool will be lighter. It’s darker if you ate a dish with nori, a black burger. In addition, it is worth thinking about drugs or dietary supplements that you can take – bismuth and iron preparations give dark, closer to green stools.

Warning symptoms not to be ignored

1. Smaller stools (less than 1 every 2 days or 3 times a week) or frequent stools (more than 2, rarely 3 times a day).
2. Changes in shape and consistency. We will continue to get acquainted with the Bristol scale, not the norm in it: fragmented, “sheep” or dense, type 1-2 feces and, in contrast to it, mushy or watery stools, stools in separate flakes – type 6-7.
3. Unstable stools – alternation of its consistency and frequency without any regularity, then 1 time per day, then 5, then type 3 on the Bristol scale, then 6. It is also important to notice what sensations accompanied the alternation of stool (good / bad).
4. Color change. Pay attention to very light, closer to gray stools or very dark, black stools. Often yellow stools are also a sign of abnormality.
5. The appearance of impurities in the feces is perhaps the most formidable, but a clear symptom:

   🔸Blood. It can be scarlet, dark, it can be changed black. It can be in scarce amounts, only on a piece of paper or on the surface of the stool, it can be mixed with feces. It may drip or stand out excessively, but here you yourself will call an ambulance team without much thought.

   There are many diseases, a disturbing symptom, however, one should not be afraid of examination, it is better than reaping the fruits of inaction.

   🔸 Slime. Often we are faced with a misunderstanding of this term. I would describe it as follows: a clear viscous liquid, resembling saliva, can be mixed with the stool, can be separated on its own. May be released as foam.

   🔸 A yellow-green admixture in the stool can be a sign of the presence of pus, which means inflammation, or an accelerated passage of bile through the gastrointestinal tract.

   🔸Undigested pieces of food – the result of an accelerated work of the gastrointestinal tract and incomplete processing of the food product, pay attention to their composition (meat / vegetables), especially alarming if you see food consumed during the day.

6. Ineffective or excessive urge to stool, as well as the absence of an urge to stool, may not be the norm, pay attention to this.

In case of abnormalities, consult a gastroenterologist.

Fecal tests for diagnosing bowel diseases

Tracking stool parameters is a simple and effective method that can be used for preliminary diagnosis. If deviations from the norm have appeared, in addition to consulting a gastroenterologist, stool tests will be required to help establish the cause of these deviations. Fecal analyzes are powerful non-invasive diagnostic tools.

Coprogram or general fecal analysis is the most famous, proven analysis. It examines the components of the processing of all foods (proteins, fats, carbohydrates), mucus, visible blood, inflammatory cells, sometimes even protozoan cysts or helminth eggs can be identified and described.

Fecal occult blood is a more accurate method for detecting blood in the stool, including altered, from the upper GI tract, in minimal quantities.

Fecal calprotectin – assay to detect inflammation in the intestine. It is especially interesting as a screening in older people in conjunction with feces for occult blood.

Eosinophilic neurotoxin is an indicator of an allergic reaction in the gastrointestinal tract.

Pancreatic elastase is useful for patients with chronic pancreatitis to determine the degree of production of pancreatic enzymes.

Stool culture for dysbacteriosis to detect deviations in the composition of the microflora, the growth of pathogenic and opportunistic flora.

Also do not lose their relevance stool tests for helminths and protozoa . There are many of them, starting from microscopic examination by the Parasep enrichment method, up to high-precision PCR reactions separately for each type of pathogen or a panel of the most common ones.

For the interpretation of the tests, I recommend that you consult a doctor.

How to do a stool test correctly?

Proper preparation and collection of stool samples will ensure the correct result. All stool tests must be taken in a special container on the day of collection; the collected samples should be stored in the refrigerator for no more than 6-8 hours. The collection of stool samples is carried out in a natural way, without the use of enemas and laxatives, urine should not get into the tests. The container must be filled 1/3. Some stool tests require special preparation before taking them.

To prepare for a coprogram, skip a week or more after taking antibiotics. Before analysis, do not take laxatives, enzymes, sorbents, do not use rectal suppositories and ointments.

Before testing for occult bleeding of the gastrointestinal tract, a 4-5-day diet is recommended with the exclusion of meat, offal (liver, heart), fish, as well as iron, magnesium and bismuth preparations. However, when testing stool for occult blood using the Colonview method, only restriction of the above drugs is recommended.

A special container is used for tests for helminth eggs, cysts and vegetative forms of protozoa, as well as for inoculation for intestinal dysbacteriosis.

At GC Expert, you can get a consultation with a gastroenterologist specializing in the diagnosis and treatment of intestinal diseases, pass all the above tests or undergo a comprehensive diagnosis under the “Check-up intestines” program in two days.

Be healthy! Sincerely, gastroenterologist-nutritionist Svetlana Igorevna Kovaleva.

Feces in colon cancer: stool color in adult oncology, mucus, types of feces, photo with explanations

Changes in feces in cancer are different. Oncological diseases, including malignant tumors of the intestine, are dangerous because they do not cause any symptoms for a long time. But even when cancer symptoms appear, they are non-specific. The symptoms of bowel cancer are very similar to those of other diseases. A person may think for a long time that he has an intestinal disorder, because he “ate something wrong”, or some kind of infection, or hemorrhoids, or a violation of the stool due to problems with the liver, pancreas.

It is important to take good care of your health. If you have unusual stool changes and other symptoms that persist for a long time, see your doctor and get tested. In most cases, this is not an oncological disease, but there is always a chance. If the symptoms are still caused by cancer, it is important to diagnose it as soon as possible and start treatment.

What are the symptoms of colon and rectal cancer?

The main manifestations that can occur with bowel cancer:

• Diarrhea or constipation that persists for several days.
• Change in the appearance of feces. It becomes thin, like a pencil, due to the fact that the tumor narrows the intestinal lumen.
• After going to the toilet, there is a feeling of discomfort, a feeling that the bowel has not been completely emptied.
• Bleeding from the rectum.
• Blood in the stool.
• Dark, tarry stools – in medical language, this appearance of feces is called chalky . More often this symptom occurs with lesions of the upper gastrointestinal tract.
• Pain, cramps in the abdomen.
• Unexplained weight loss.
• Constant weakness, increased fatigue.

Why should I get tested as soon as possible? If these symptoms are caused by cancer, then they indicate that the tumor has already grown quite strongly or has managed to spread in the body. The more time passes, the more the cancer progresses. This means that the prognosis worsens, the chances that the disease can be dealt with are reduced.

Changes in bowel habits

Bowel cancer often manifests as changes in bowel frequency, quantity and consistency of stools. Some patients are concerned about constipation, a condition in which the passage of stool through the intestine is impaired. It manifests itself with symptoms such as:

• Absence of stool for more than three days.
• Pain, discomfort, abdominal cramps.
• The volume of feces decreases, it becomes dense.
• An unpleasant feeling of discomfort in the abdomen, a feeling of “fullness”.
• Bloating, an increase in the volume of the abdomen.
• Belching, gas.

Cancer sometimes develops acute intestinal obstruction is a life-threatening condition. It manifests itself in the form of severe cramping pains in the abdomen, constipation, nausea, and vomiting. Due to a drop in the level of protein in the blood, edema develops, and due to fluid loss, dehydration. Rotting begins in the intestines, toxic products enter the bloodstream and poison the body. necrosis (necrosis) of the intestinal wall develops, its contents enter the abdominal cavity and lead to peritonitis. If a patient with acute intestinal obstruction is not provided with timely medical care, he will most likely die within 4-6 hours.

Euroonco offers all types of treatment for intestinal obstruction. Our surgeons perform operations on the intestines, install stents, apply ileostomies and colostomies. Patients who develop emergency conditions receive treatment in intensive care and intensive care units equipped with modern equipment.

Diarrhea is a condition in which frequent stools are noted – 3 or more times within 24 hours, while the feces have a liquid consistency. Sometimes pain and discomfort in the stomach bothers, sometimes not. If diarrhea persists for several days, you should consult a doctor.

Constipation and diarrhea can be caused not only by cancer, but also occur as side effects of chemotherapy, radiation therapy. In order to cope with this symptom, the doctor may give some recommendations about diet and lifestyle, and prescribe medications. Diarrhea caused by chemotherapy usually resolves within 3 weeks after cancer treatment is completed.

Severe diarrhea, even if it is not caused by cancer, is dangerous because it leads to loss of fluid, electrolytes, and intestinal absorption of nutrients. This is fraught with dehydration, exhaustion, electrolyte imbalance.

Changes in the appearance of stools

Changes in the appearance of feces may indicate that there is cancer or other pathological process in the intestines. With constipation, it becomes more dense, with diarrhea – mushy, liquid. If the cancer partially blocks the intestinal lumen, the stool becomes thin, like a pencil (“ribbon stool”). In addition to cancer and benign neoplasms of the intestine, this symptom can be caused by diseases such as hemorrhoids, irritable bowel syndrome, colitis, parasites.

Discoloration of stools

With bowel cancer, stools can turn black, look like tar and have an unpleasant odor. Such stool is called melena, and it looks like this because the blood is exposed to digestive juices in the stomach, intestines. Thus, melena can be a manifestation of cancer of the esophagus, stomach, less often – cancer of the small intestine.

In order for the stool to darken and take on a tarry appearance, at least 500 ml of blood must enter the intestines. If such a symptom occurs, you should immediately consult a doctor!

If there is a suspicion of bleeding in the digestive tract, which is not manifested in a change in the appearance of feces (the so-called occult bleeding), a stool test for occult blood is prescribed. The most common type of study is benzidine test (Gregersen reaction) . This laboratory diagnostic method plays an important role in the detection of cancer and some other diseases, it is indicated in the following cases:

• Prolonged constipation, diarrhea, mushy stools.
• Pain in the abdomen.
• False urge to defecate.
• Unexplained loss of appetite, weight.
• If cancer is detected during a colonoscopy (endoscopy of the colon).
• If tumors or ulcers are detected during FEGDS (endoscopic examination of the esophagus, stomach, duodenum).

Fecal occult blood test is a very sensitive test. It can show a positive result in nosebleeds, bleeding gums. This must be taken into account and the results of the analysis should be evaluated in combination with other diagnostic methods.

Bleeding from the rectum, blood in the stool

If the source of bleeding is in the lower intestine, the patient may experience the following symptoms:

• traces of blood on toilet paper;
• traces of blood on underwear, sheets;
• streaks of blood in feces;
• bleeding from the rectum.

If you notice more than two traces of blood on toilet paper, blood in the stool, or bright scarlet blood coming out of the rectum, you should immediately consult a doctor.

Mucus in the feces in an adult

Mucus in the stool in an adult is not a typical manifestation of malignant tumors of the intestine. Cancer is suspected when this symptom is combined with others, such as bleeding, chronic diarrhea, etc.

Most often, jelly-like mucus in the stool or even mucus instead of stool (excreted between bowel movements) are signs of infections in the intestines. Sometimes they are caused by a decrease in the tone of the sphincter muscle of the rectum. In any case, in order to exclude cancer or other serious disease, it is better to immediately visit a doctor and get checked.

Prevention and early diagnosis of bowel cancer

If a patient has fecal changes, they are referred to a coloproctologist. During the appointment, the doctor finds out what symptoms bother the patient, for how long, what he has been ill for during his life, and whether there are any intestinal pathologies in close relatives. Then a digital examination of the rectum is performed.

In order to detect cancer and other bowel pathologies, the following tests are used:

• Proctoscopy and colonoscopy – endoscopic examination of the rectum and colon. These diagnostic methods allow you to visualize cancer, polyp and other pathological changes.
• Biopsy is an examination that can be done during an endoscopy. The doctor, using a special tool, receives a fragment of a pathologically altered area of ​​the intestinal mucosa and sends it to the laboratory, where it is examined under a microscope. If malignant cells are found, it is cancer.
• Fecal occult blood test.
• Complete blood count – helps to detect anemia as a result of bleeding.
• If bowel cancer has already been diagnosed, a blood chemistry test is done to evaluate liver function, as there may be cancer metastases in the liver.
• Blood test for tumor markers: cancer embryonic antigen (CEA) and CA 19-9 . This study is not very informative in the diagnosis of cancer, as it can give false positive and false negative results. Tests for tumor markers are used as part of a comprehensive examination to monitor the effectiveness of treatment and detect relapse.
• Once colorectal cancer is diagnosed, CT scans, ultrasound, MRI, angiography, chest X-ray, PET scans are done to evaluate its spread and stage.

Screening tests help diagnose cancer before stool changes occur. Colonoscopy is used as the main type of screening. It is recommended for all people over 50 years of age. At Euroonco, this study is performed by experienced doctors using modern equipment. In order for the patient not to experience discomfort during the procedure, our doctors immerse him in a state of light anesthesia – “medicated sleep”.

Prevention of colon cancer

To reduce the risk of colorectal cancer, follow these guidelines:

• Maintain a healthy weight.
