500 Glucose Level: Understanding Diabetic Coma Symptoms, Causes, and Prevention
What are the symptoms of a diabetic coma. How can high or low blood sugar lead to unconsciousness. What factors increase the risk of diabetic coma. How can diabetic coma be prevented and managed effectively.
What is a Diabetic Coma?
A diabetic coma is a severe, life-threatening condition that occurs in people with diabetes. It is characterized by a state of unconsciousness where the individual is alive but unable to respond to external stimuli. This medical emergency can result from either extremely high blood sugar (hyperglycemia) or dangerously low blood sugar (hypoglycemia).
Why is a diabetic coma so dangerous? The primary concern is that if left untreated, it can lead to death. The brain requires a constant supply of glucose to function properly, and any extreme fluctuation in blood sugar levels can disrupt this delicate balance, potentially causing irreversible damage.
Recognizing the Symptoms of High and Low Blood Sugar
Understanding the symptoms that precede a diabetic coma is crucial for early intervention and prevention. These symptoms typically manifest before the onset of unconsciousness and vary depending on whether the blood sugar is too high or too low.
Hyperglycemia (High Blood Sugar) Symptoms
- Increased thirst and frequent urination
- Blurred vision
- Fatigue or weakness
- Headache
- Nausea and vomiting
- Shortness of breath
- Stomach pain
- Fruity breath odor
- Extreme dry mouth
Hypoglycemia (Low Blood Sugar) Symptoms
- Shakiness and anxiety
- Tiredness or drowsiness
- Weakness and sweating
- Intense hunger
- Tingling sensation on the skin
- Dizziness or lightheadedness
- Difficulty speaking
- Confusion
- Loss of consciousness (in severe cases)
How can you differentiate between high and low blood sugar symptoms? While some symptoms overlap, the presence of increased thirst and frequent urination is typically associated with high blood sugar, whereas sudden onset of shakiness, sweating, and confusion is more indicative of low blood sugar.
The Dangers of Hypoglycemia Unawareness
Some individuals with longstanding diabetes may develop a condition known as hypoglycemia unawareness. This phenomenon occurs when the body loses its ability to recognize the early warning signs of low blood sugar. Why is this particularly dangerous? Without these warning symptoms, a person may not realize their blood sugar is dropping to critically low levels, increasing the risk of severe hypoglycemia and potential diabetic coma.
How can someone with hypoglycemia unawareness protect themselves? Regular blood sugar monitoring becomes even more crucial for these individuals. They may need to check their levels more frequently and work closely with their healthcare provider to adjust their diabetes management plan accordingly.
Understanding the Causes of Diabetic Coma
A diabetic coma can result from three main conditions, all of which stem from severe imbalances in blood sugar levels:
1. Diabetic Ketoacidosis (DKA)
Diabetic ketoacidosis occurs when the body, starved for energy, begins breaking down fat for fuel. This process produces toxic acids called ketones. When ketones build up in the blood alongside high blood sugar levels, it can lead to DKA and potentially a diabetic coma.
Who is most at risk for DKA? While it’s most common in people with type 1 diabetes, it can also occur in those with type 2 or gestational diabetes under certain circumstances.
2. Diabetic Hyperosmolar Syndrome
This condition develops when blood sugar levels become extremely elevated, typically above 600 mg/dL (33.3 mmol/L). The excess sugar in the blood causes fluid to be drawn out of the body’s tissues, leading to severe dehydration. If left untreated, this can progress to a diabetic coma.
3. Severe Hypoglycemia
When blood sugar drops too low, it can deprive the brain of the glucose it needs to function. In severe cases, this can cause loss of consciousness and potentially lead to a diabetic coma.
How quickly can these conditions progress to a coma? The timeline can vary depending on the individual and the severity of the blood sugar imbalance, but it’s crucial to treat any extreme fluctuations in blood sugar promptly to prevent progression to a coma.
Risk Factors for Diabetic Coma
While anyone with diabetes is potentially at risk for a diabetic coma, certain factors can increase this risk significantly:
- Insulin delivery problems: For those using insulin pumps, malfunctions or catheter issues can lead to insufficient insulin delivery, increasing the risk of DKA.
- Illness, trauma, or surgery: These stressors can cause significant fluctuations in blood sugar levels.
- Poor diabetes management: Inconsistent monitoring of blood sugar or not following prescribed treatment plans can lead to long-term complications and increased coma risk.
- Intentional insulin omission: Some individuals with diabetes and eating disorders may deliberately skip insulin doses to lose weight, a dangerous practice that significantly increases the risk of diabetic coma.
- Alcohol consumption: Alcohol can have unpredictable effects on blood sugar and may mask hypoglycemia symptoms.
- Illegal drug use: Substances like cocaine can interfere with blood sugar regulation.
How can these risk factors be mitigated? Education, regular medical check-ups, and strict adherence to diabetes management plans are key to reducing the risk of diabetic coma.
Prevention and Management Strategies
Preventing a diabetic coma involves a multifaceted approach to diabetes management:
- Regular blood sugar monitoring
- Adherence to prescribed medication regimens
- Balanced diet and regular exercise
- Stress management
- Regular medical check-ups
- Education on recognizing and responding to blood sugar fluctuations
What role does lifestyle play in preventing diabetic comas? A healthy lifestyle that includes a balanced diet, regular physical activity, and stress management can significantly reduce the risk of severe blood sugar fluctuations and, consequently, the risk of diabetic coma.
Emergency Response to Diabetic Coma
Recognizing and responding quickly to the signs of an impending diabetic coma is crucial. If someone with diabetes exhibits symptoms of severe high or low blood sugar and appears to be losing consciousness, immediate medical attention is necessary.
How should you respond if you suspect someone is entering a diabetic coma?
- Call emergency services immediately.
- If the person is conscious and able to swallow, and you suspect low blood sugar, give them a fast-acting source of sugar (e.g., fruit juice, glucose tablets).
- Do not attempt to give an unconscious person food or drink.
- If available and you’re trained to use it, administer glucagon for severe hypoglycemia.
- Stay with the person until medical help arrives.
Why is rapid response so critical in cases of suspected diabetic coma? The sooner medical treatment is initiated, the better the chances of preventing long-term complications or fatality.
Long-term Management and Living with Diabetes
While the risk of diabetic coma is a serious concern for people with diabetes, it’s important to remember that with proper management, this condition is largely preventable. Long-term strategies for living well with diabetes include:
- Continuous glucose monitoring systems for real-time blood sugar tracking
- Regular consultations with endocrinologists and diabetes educators
- Participation in diabetes support groups
- Staying informed about advances in diabetes treatment and management
How can technology assist in diabetes management? Modern innovations like continuous glucose monitors and insulin pumps with predictive algorithms can provide early warnings of blood sugar trends, helping to prevent extreme fluctuations that could lead to a diabetic coma.
Living with diabetes requires vigilance and commitment to self-care, but it doesn’t have to be a constant source of fear. By understanding the risks, recognizing the symptoms, and following a comprehensive management plan, individuals with diabetes can lead full, active lives while minimizing the risk of severe complications like diabetic coma.
Remember, diabetes management is a collaborative effort between the individual and their healthcare team. Regular check-ups, open communication about any challenges or concerns, and a willingness to adapt management strategies as needed are all crucial components of effective long-term diabetes care.
By staying informed, proactive, and engaged in their health care, people with diabetes can significantly reduce their risk of experiencing a diabetic coma and other serious complications. With the right knowledge, tools, and support, living well with diabetes is not just possible—it’s achievable for millions of people around the world.
Diabetic coma – Symptoms & causes
Overview
A diabetic coma is a life-threatening disorder that causes unconsciousness. If you have diabetes, dangerously high blood sugar (hyperglycemia) or dangerously low blood sugar (hypoglycemia) can lead to a diabetic coma.
If you go into a diabetic coma, you’re alive — but you can’t wake up or respond purposefully to sights, sounds or other types of stimulation. If it’s not treated, a diabetic coma can result in death.
The idea of a diabetic coma can be scary, but you can take steps to help prevent it. One of the most important is to follow your diabetes treatment plan.

Symptoms
Symptoms of high blood sugar or low blood sugar usually develop before a diabetic coma.
High blood sugar (hyperglycemia)
If your blood sugar level is too high, you may have:
- Increased thirst
- Frequent urination
- Blurred vision
- Tiredness or weakness
- Headache
- Nausea and vomiting
- Shortness of breath
- Stomach pain
- Fruity breath odor
- A very dry mouth
Low blood sugar (hypoglycemia)
If your blood sugar is too low, you may have:
- Shakiness
- Anxiety
- Tiredness or drowsiness
- Weakness
- Sweating
- Hunger
- A feeling of tingling on your skin
- Dizziness or lightheadedness
- Headache
- Difficulty speaking
- Blurry vision
- Confusion
- Loss of consciousness
Some people, especially those who’ve had diabetes for a long time, develop a condition known as hypoglycemia unawareness. That means they don’t have warning symptoms that signal a drop in blood sugar.
If you have any symptoms of high or low blood sugar, test your blood sugar right away. Based on the test results, follow your diabetes treatment. If you don’t start to feel better quickly, or you start to feel worse, get medical care right away.
When to see a doctor
A diabetic coma is a medical emergency. If you have symptoms of high or low blood sugar and you think you might pass out, call 911 or your local emergency number.
If you’re with someone with diabetes who has passed out, call for emergency help. Tell the emergency personnel that the unconscious person has diabetes.
Causes
Blood sugar that’s either too high or too low for too long may cause the following serious health problems, all of which can lead to a diabetic coma.
Diabetic ketoacidosis. If your muscle cells become starved for energy, your body may start breaking down fat for energy.
This process forms toxic acids known as ketones. If you have ketones (measured in blood or urine) and high blood sugar, the condition is called diabetic ketoacidosis. If it’s not treated, it can lead to a diabetic coma.
Diabetic ketoacidosis is most common in people who have type 1 diabetes. But it can also occur in people who have type 2 diabetes or gestational diabetes.
Diabetic hyperosmolar syndrome. If your blood sugar level goes above 600 milligrams per deciliter (mg/dL), or 33.3 millimoles per liter (mmol/L), the condition is called diabetic hyperosmolar syndrome.
When blood sugar is very high, the extra sugar passes from the blood into the urine. That triggers a process that draws a large amount of fluid from the body. If it isn’t treated, this can lead to life-threatening dehydration and a diabetic coma.
- Hypoglycemia. Your brain needs sugar (glucose) to function. In severe cases, low blood sugar (hypoglycemia) may cause you to pass out.
Low blood sugar can be caused by too much insulin or not enough food. Exercising too vigorously or drinking too much alcohol can have the same effect.
Risk factors
Anyone who has diabetes is at risk of a diabetic coma, but the following factors can increase the risk:
- Insulin delivery problems. If you’re using an insulin pump, you have to check your blood sugar frequently. Insulin delivery can stop if the pump fails or if the tubing (catheter) becomes twisted or falls out of place. A lack of insulin can lead to diabetic ketoacidosis.
- An illness, trauma or surgery. When you’re sick or injured, blood sugar levels can change, sometimes significantly, increasing your risk of diabetic ketoacidosis and diabetic hyperosmolar syndrome.
- Poorly managed diabetes. If you don’t monitor your blood sugar properly or take your medications as directed by your health care provider, you have a higher risk of developing long-term health problems and a higher risk of diabetic coma.
- Deliberately skipping meals or insulin. Sometimes, people with diabetes who also have an eating disorder choose not to use their insulin as they should, in the hope of losing weight. This is a dangerous, life-threatening thing to do, and it raises the risk of a diabetic coma.
- Drinking alcohol. Alcohol can have unpredictable effects on your blood sugar. Alcohol’s effects may make it harder for you to know when you’re having low blood sugar symptoms. This can increase your risk of a diabetic coma caused by hypoglycemia.
- Illegal drug use. Illegal drugs, such as cocaine, can increase your risk of severe high blood sugar and conditions linked to diabetic coma.
Complications
If it is not treated, a diabetic coma can lead to permanent brain damage and death.
Prevention
Good day-to-day control of your diabetes can help you prevent a diabetic coma. Keep these tips in mind:
- Follow your meal plan.
Consistent snacks and meals can help you control your blood sugar level.
- Keep an eye on your blood sugar level. Frequent blood sugar tests can tell you whether you’re keeping your blood sugar level in your target range. It also can alert you to dangerous highs or lows. Check more frequently if you’ve exercised. Exercise can cause blood sugar levels to drop, even hours later, especially if you don’t exercise regularly.
- Take your medication as directed. If you have frequent episodes of high or low blood sugar, tell your health care provider. You may need to have the dose or the timing of your medication adjusted.
- Have a sick-day plan. Illness can cause an unexpected change in blood sugar. If you are sick and unable to eat, your blood sugar may drop. While you are healthy, talk with your doctor about how to best manage your blood sugar levels if you get sick. Consider storing at least a week’s worth of diabetes supplies and an extra glucagon kit in case of emergencies.
- Check for ketones when your blood sugar is high. Check your urine for ketones when your blood sugar level is over 250 milligrams per deciliter (mg/dL) (14 millimoles per liter (mmol/L)) on more than two consecutive tests, especially if you are sick. If you have a large amount of ketones, call your health care provider for advice. Call your health care provider immediately if you have any level of ketones and are vomiting. High levels of ketones can lead to diabetic ketoacidosis, which can lead to coma.
- Have glucagon and fast-acting sources of sugar available. If you take insulin for your diabetes, have an up-to-date glucagon kit and fast-acting sources of sugar, such as glucose tablets or orange juice, readily available to treat low blood sugar levels.
Consider a continuous glucose monitor, especially if you have trouble maintaining stable blood sugar levels or you don’t feel symptoms of low blood sugar (hypoglycemia unawareness).
Continuous glucose monitors are devices that use a small sensor inserted underneath the skin to track trends in blood sugar levels and send the information to a wireless device, such as a smart phone.
These monitors can alert you when your blood sugar is dangerously low or if it is dropping too fast. But you still need to test your blood sugar levels using a blood glucose meter even if you’re using one of these monitors. Continuous glucose monitors are more expensive than other glucose monitoring methods, but they may help you control your glucose better.
- Drink alcohol with caution. Because alcohol can have an unpredictable effect on your blood sugar, have a snack or a meal when you drink alcohol, if you choose to drink at all.
- Educate your loved ones, friends and co-workers. Teach loved ones and other close contacts how to recognize the early symptoms of blood sugar extremes and how to give emergency injections. If you pass out, someone should be able to call for emergency help.
- Wear a medical identification bracelet or necklace. If you’re unconscious, the bracelet or necklace can provide valuable information to your friends, co-workers and emergency personnel.
Continuous glucose monitor and insulin pump
A continuous glucose monitor, on the left, is a device that measures blood sugar every few minutes using a sensor inserted under the skin. An insulin pump, attached to the pocket, is a device that’s worn outside of the body with a tube that connects the reservoir of insulin to a catheter inserted under the skin of the abdomen. Insulin pumps are programmed to deliver specific amounts of insulin continuously and with food.

What is the norm of blood sugar and what to do if it is high or low
Likbez
Health
January 25, 2022
Get your glucose tested at least every three years.
Why blood sugar is needed
In fact, we are not talking about sugar, but about glucose. Sugar, like any other carbohydrate, is not absorbed by the body directly: it is broken down in the intestines to simple sugars (monosaccharides) and enters the blood in the form of glucose.
A healthy 70 kg person has approximately 1 teaspoon (4 grams) of glucose in their blood at all times.
This substance is the main source of energy for all body cells. It is thanks to him that we have the strength to breathe, move, learn and think.
How blood sugar is measured and what is considered normal
In international practice, blood sugar (glycemia) is measured in the so-called molar concentration – millimoles per liter (mmol/l). In the United States, Germany, and some other countries, mass concentrations are also common, in milligrams per deciliter (mg/dL). To convert one concentration to another, it is enough to remember this equality: 1 mmol / l \u003d 18 mg / dl.
A blood sugar test is done on an empty stomach, usually in the morning. This is important because any food you eat can raise your glucose levels.
Sample can be taken from a finger or a vein. Venous blood tests give a more accurate result.
Fasting blood glucose from a vein is between 3.9 and 5.6 mmol/L (70-100 mg/dL).
If the test result is different from the norm, this means the following:
- From 5.6 to 6.9 mmol / l – the so-called prediabetes. This is a slight increase in blood sugar levels, which means that something is going on in your body that increases the risk of developing diabetes.
- 7 mmol/l and above – hyperglycemia (increased blood glucose level). Most often, the violation speaks of diabetes mellitus.
- Below 3.9 mmol/l, hypoglycemia (low blood glucose). This is also an unhealthy condition that can be a sign of a number of disorders in the body.
Please note: when testing blood from a finger, the normal values shift – up to the range of 3.3-5.5 mmol / l.
Why blood sugar changes
The body regulates the amount of glucose in the blood by:
- enzymes that help break down carbohydrates in the intestines and thus affect the rate at which glucose enters the bloodstream;
- hormones that determine how quickly the cells of the body will consume sugar from the blood.
Essential enzymes are produced by the pancreas. It also produces insulin, a key hormone that allows cells to absorb glucose. If there is too little insulin, or, for example, cells stop responding to it for some reason (this is called insulin resistance), blood sugar levels rise. In the first situation, they speak of type 1 diabetes, in the second, of type 2 diabetes.
Glycemia is also affected by the work of:
- the liver and kidneys, which purify the blood from excess glucose and remove the substance from the body;
- thyroid gland: hormones secreted by it determine the rate at which cells consume sugar from the blood;
- adrenal glands. This paired endocrine gland also produces hormones (such as adrenaline) that regulate metabolic rate.
What is the danger of abnormal sugar levels
Both hypo- and hyperglycemia affect well-being. First of all, the brain suffers, since its cells consume about half (up to 60% – if we are talking about a hungry or inactive person) of all the energy supplied by glucose.
Dizziness, loss of concentration, weakness, blurred vision, trembling hands are common symptoms for both low and high blood sugar levels. But abnormal glycemia, in addition to feeling unwell, has other, more serious consequences.
With constant hyperglycemia, glucose accumulates in organs and tissues and becomes toxic – it begins to destroy the liver, kidneys, retina, blood vessels, heart, and nervous system. With a lack of sugar, the cells of the body are chronically lacking nutrition, and this also leads to damage to vital organs.
Why blood sugar levels are high
Most often this indicates a pre-diabetic state or diabetes mellitus that has already occurred. However, other medical problems can also lead to an increase in glycemia.
- Hyperthyroidism. This is a condition in which the thyroid gland produces too many hormones.
- Pancreatitis is an inflammation of the pancreas.
- Severe stress.
- Trauma or surgery.
- Liver diseases.
- Stroke.
- Pancreatic cancer, as well as other rarer tumors.
Why blood sugar levels are low
Hypoglycemia is also a common companion of diabetes. It occurs when a person suffering from this disease takes too much insulin by mistake. But other reasons for low blood glucose levels are also possible.
- Insufficient nutrition. The amount of sugar in your blood drops if you are on a too rigid diet or suffer from an eating disorder such as anorexia or bulimia.
- Too strenuous and long exercise. Let’s say you just ran a marathon, rode a few tens of kilometers on a bike, or just dug a garden, forgetting about lunch.
- Hypothyroidism. This is a condition in which the thyroid gland produces too little hormone.
- Diseases of the adrenal glands, pituitary gland, liver or kidneys.
How to know if your blood sugar level is abnormal
It is almost impossible to do this without a blood test. The fact is that the characteristic symptoms of a decrease or increase in glucose levels can be easily confused with ordinary fatigue or, for example, a reaction to weather changes.
In order not to miss the developing hypo- or hyperglycemia and the diseases that caused it, doctors – both Western and Russian – recommend regularly testing blood sugar levels.
Donate blood for sugar at least once every three years. This is especially important for people over 45.
In addition, it is recommended to do the analysis as soon as possible if you have signs of diabetes:
- urination becomes more frequent;
- you have put on a lot of weight;
- your eyesight is getting worse;
- weakness regularly rolls up, up to darkening in the eyes.
What to do if your blood sugar is low or high
This situation should definitely be discussed with the therapist. The doctor will determine the causes of hypo- or hyperglycemia, make an accurate diagnosis and give instructions on how to return the glucose level to normal.
Depending on the diagnosis, the physician may prescribe medication. Some of them may have to take a lifetime.

How to properly prepare for a blood sugar (glucose) test. Preparing for sugar analysis.
What does a blood sugar test show?
The analysis shows the level of sugar (glucose) in the blood, which can indicate the presence of diabetes and other diseases.
Low sugar levels (hypoglycemia) can signal diseases of the pancreas, liver, kidneys and adrenal glands, as well as the hypothalamus.
The most common cause of high blood sugar (hyperglycemia) is diabetes mellitus. Hyperglycemia can also speak of other endocrine diseases, problems of the liver and hypothalamus, and a constant inflammatory process in the body.
There is also a glucose tolerance test (aka glucose tolerance test or GTT), which is carried out to detect prediabetes, and is also prescribed for pregnant women.
Indications for analysis
Symptoms that may be caused by low blood sugar include:
- constant lethargy, fatigue;
- increased sweating;
- anxiety;
- bouts of hunger.
Symptoms that high blood sugar can cause include:
- rapid breathing;
- dry mouth, thirst;
- dry skin;
- decreased clarity of vision;
- frequent urge to urinate;
- poor wound healing;
- itching of the skin and mucous membranes;
- weight loss.
If you notice some of the listed symptoms behind you, make an appointment with a general practitioner, he will diagnose and write out a referral for the necessary analysis.
With both deviations from the norm, an unstable mental state, mood swings can be observed.
How sugar is tested
A blood sugar test is done by taking blood either from a finger (capillary blood) or from a vein under the elbow (venous blood).
Blood sugar norms
l The norm of blood sugar in an adult is:
- 3.3–5.5 mmol/l (for capillary blood sampling)
- 3.7–6.1 mmol/L (at sampling)
If the mark exceeds 6.1 mmol/l, it is necessary to be examined.
In order for your results to be reliable, you need to properly prepare for the test for sugar.
How to take a blood sugar test
So that the test results do not turn out to be false, it is necessary to follow some rules for preparing the patient for a blood test for sugar. Otherwise, you may need to retake the analysis (and this is a waste of your time and money), or an incorrect diagnosis and treatment may be prescribed.
Can I drink water before the sugar test?
You can drink water. But no more – it is necessary to exclude alcoholic and containing sugar and sweeteners drinks.
Preparing for a glucose test
- On an empty stomach. 8-hour or better 12-hour fasting. Drink only water. Alcohol (for 102 days it is better to exclude) and sweet drinks are strictly prohibited.
- Better sleep well
- Avoid intense mental work, stress and outbursts of emotions. The body can increase blood glucose levels during a stressful situation. Excessive emotions can suppress insulin production.
- It is best not to brush your teeth with sugary toothpaste.
- No smoking. (with diabetes it is better to exclude smoking altogether)
- Be careful with medication. If necessary, treatment of acute or chronic episodes of the disease should warn the doctor about the existing problems and reschedule the study or interpret its results in accordance with the ability of some drugs to raise or lower the studied parameters
- During the period of colds or other acute infections, the result may be false positive
