What causes nausea? 12 common causes and their treatments

Several conditions can cause nausea, including stress, anxiety, infections, and motion sickness. Occasional temporary nausea is also common but typically not cause for concern.

Nausea is a sensation that makes a person feel they need to vomit. Sometimes, individuals with nausea do vomit, but not always.

In this article, we explore what triggers nausea, including a list of 12 common causes. We will also discuss some of these conditions in more detail and describe their symptoms and treatments.

Several types of infection may cause nausea, including:

Food poisoning or stomach flu

Gastrointestinal infections, such as those caused by food poisoning or viruses, are among the most common reasons for nausea.

Symptoms may include:

• nausea
• stomach pain or cramping
• vomiting
• diarrhea

Food poisoning occurs when a person ingests food or drink containing a virus, toxin, or bacterium, such as Salmonella and Escherichia coli. Other gastrointestinal viruses, such as norovirus or rotavirus, occur due to close contact with someone who is sick.

These infections usually clear up on their own at home. Drinking enough fluids and electrolytes is important for preventing dehydration, particularly in young children.

Flu and COVID-19

Other types of viral infection can also trigger nausea, such as flu and COVID-19. The symptoms of COVID-19 include:

• fever or chills
• loss of taste or smell
• cough
• shortness of breath
• fatigue
• headache
• body aches
• blocked or runny nose
• sore throat
• nausea
• vomiting
• diarrhea

A 2021 review found that out of 6,335 people with COVID-19, 79% experienced nausea.

People with flu can also have many of these symptoms. Nausea is more common in children with flu compared to adults, but both groups may experience it.

Because the symptoms of COVID-19 are similar to those of flu and can vary from person to person, it is important to stay at home and follow local guidelines if someone has any symptoms that may indicate COVID-19.

A range of digestive disorders can induce nausea, including:

• Gastritis: Acid or a bacterium called H. pylori often cause inflammation of the stomach, which can lead to stomach ulcers.
• Gastroparesis: With this condition, the stomach empties much slower than it should. Certain medications or nerve damage usually cause this, which is common in people with diabetes.
• Gastroesophageal reflux disease: Triggers chronic acid reflux and indigestion.
• IBS: Causes stomach cramping, along with diarrhea or constipation.
• Celiac disease: An autoimmune condition that causes symptoms in response to gluten.
• Gallbladder conditions: Includes issues such as gallstones.
• Pancreas conditions: Includes issues such as pancreatitis.

Typically, nausea is not the only symptom of chronic digestive disorders. A person may also experience:

• abdominal bloating or fullness
• gas or belching
• heartburn or indigestion
• diarrhea, constipation, or both
• abdominal pain and cramping
• reactions or intolerance to specific foods or food groups

The diagnosis and treatment for digestive disorders vary depending on the cause. They may involve a combination of medications, dietary or lifestyle changes, or in some cases, medical procedures.

Mental health and digestive health are closely linked. People with mental health conditions can experience digestive symptoms, including nausea. Similarly, stress can also exacerbate digestive conditions.

People who frequently feel stressed, anxious, or panicked may have an anxiety disorder. The symptoms of anxiety include:

• nausea
• rapid heartbeat
• quick or shallow breathing
• choking sensation in the throat
• sweating
• dizziness
• tense muscles

Severe anxiety can also trigger panic attacks, or in some cases, fainting. For example, people with a fear of needles or blood may experience nausea, dizziness, and loss of consciousness. This is known as vasovagal syncope.

People can also experience a phobia of nausea and vomiting itself. Doctors call this emetophobia.

Treatment for anxiety disorders typically involves talking therapy, medication to manage symptoms, or both.

The vestibular system resides in the inner ear, helping the body retain a sense of balance and know where it is relative to its surroundings. Issues with this system can cause dizziness or vertigo, which in turn causes nausea.

Conditions that may cause this include:

• Motion sickness: Occurs in response to conflicting signals of movement sent to the brain. Riding in cars, planes, or boats often triggers this.
• Labyrinthitis: An inner ear infection that can occur following a cold or flu.
• Vestibular neuritis: Occurs when the nerve inside the inner ear becomes inflamed.
• Meniere’s disease: Causes sudden episodes of dizziness, which can be severe.

The treatment for inner ear disorders can vary depending on the cause and the individual. People with an ear infection may find symptoms improve on their own over time, while over-the-counter (OTC) travel sickness medications may be enough to ease occasional motion sickness.

Those with more chronic conditions may need to try various medications, lifestyle changes, or coping techniques to manage their symptoms.

Changes in hormone levels, such as those caused by pregnancy, hormonal contraception, or endocrine disorders, may also cause nausea.

Pregnancy

Nausea is a common symptom during pregnancy. It is often known as morning sickness, although it can occur at any time. It may also develop suddenly or gradually.

Pregnant people may experience nausea when around certain foods or smells, or when they are hungry. Generally, morning sickness improves after 14 weeks.

Doctors may prescribe vitamin B6 or doxylamine to help with nausea and vomiting during pregnancy.

Thyroid disorders

The thyroid gland controls hormones that regulate the body’s metabolism. Both overactive or underactive thyroid can cause nausea.

Symptoms of an overactive thyroid, or hyperthyroidism, include:

• nervousness
• tiredness or muscle weakness
• irritability
• intolerance to heat
• difficulty sleeping
• shaky hands
• rapid heartbeat
• frequent bowel movements
• weight loss and difficulty gaining weight

Symptoms of an underactive thyroid, or hypothyroidism, include:

• tiredness
• puffy face
• weight gain and difficulty losing weight
• constipation
• intolerance to the cold
• dry skin and hair
• depression
• slower heartbeat

Doctors often treat these conditions with medication, which can also cause nausea as a side effect.

There are many ways in which changes in the brain and nervous system can cause nausea. Scientists do not fully understand all of them yet.

One of the most common neurological conditions that triggers nausea is migraine. This is a disorder that causes episodes of moderate-to-severe headache, along with other symptoms, including:

• light or sound sensitivity
• nausea
• vomiting
• aura, which are neurological changes that some people experience before pain develops

Some individuals also experience silent or acephalgic migraine, which does not cause any pain.

There are several treatments for migraine. For occasional or less severe episodes, people may find taking OTC pain medications and avoiding triggers is enough. For severe or frequent migraine, a person may need preventative medications or other therapies.

More serious neurological causes for nausea include head trauma, meningitis, or a hemorrhage.

Nausea is a common side effect of many medications, including:

• antibiotics
• antidepressants
• OTC pain medication, such as aspirin or ibuprofen
• certain supplements, such as iron
• opioids
• chemotherapy

Medications work by changing chemical processes in the brain and body. For example, neurotransmitters, such as serotonin and dopamine, can impact nausea and vomiting, so drugs that act on these chemicals can worsen or improve these symptoms.

Medication-related nausea and vomiting can be constant or occur at random intervals. It usually starts shortly after taking a new medication. Speak with a doctor if medicines could be causing nausea.

What helps people manage nausea can vary depending on the cause. For general nausea relief, the United Kingdom’s National Health Service (NHS) suggest:

• getting fresh air
• eating small, frequent meals
• staying hydrated by sipping cold drinks, such as water or juice
• drinking ginger or peppermint tea
• eating foods that contain ginger
• avoiding spicy, strong-smelling, or greasy foods

People who experience nausea because of stress or anxiety may also find breathing techniques, relaxation training, or mindfulness exercises helpful.

While home remedies can relieve the feeling of nausea, they are not a replacement for medical treatment for those with underlying conditions.

If a person frequently experiences nausea for no clear reason, they can consider speaking with a doctor to determine the cause. If the cause is psychological, speaking with a therapist may help.

Nausea is not usually an emergency. However, if it occurs alongside symptoms of a serious condition or after an injury, someone may need emergency help. Dial 911 if someone experiences nausea:

• after a recent head injury
• alongside a severe, sudden headache
• with neck stiffness, fever, headache, and vomiting

In some cases, nausea can be an early warning sign of a heart attack. This is more common in females, who can experience less obvious symptoms during a heart attack. Seek emergency help if someone has:

• pain, pressure, or squeezing in the center of the chest
• trouble breathing
• pain in one or both arms, the back, neck, or jaw
• lightheadedness
• a cold sweat

There are many potential causes of nausea. In most cases, it is not a sign of a serious illness. Many conditions that trigger nausea are treatable or temporary.

Speak with a doctor about chronic or recurring nausea, as there may be ways to reduce this symptom and improve quality of life.

Why Do I Feel Nauseous? 10 Causes Of Nausea, According To Doctors

Nausea is no joke and easily tops the list of worst feelings ever. You’ve likely experienced that sudden wave of queasiness and wanting to make it stop ASAP. It can be especially baffling when the answer to “Why do I feel nauseous?” isn’t immediately obvious, like if you haven’t eaten anything bad or your period is right on schedule.

Let’s make it clear: When you say you feel nauseous, you’re typically referring to the sensation of having to vomit or an uneasy feeling in your stomach. “It typically has to do with the body’s response to a stressor, so people start having retching, increased salivation, a feeling of vomiting, and queasiness in the stomach,” explains Camilo Ruiz, DO, an internist and sleep specialist at Sleep and Internal Medicine Specialists.

One important note: Nausea is always caused by an underlying disturbance in the body, says Thomas Vanderheyden, DO, a gastroenterologist at Michiana Gastroenterology. It is not a disease or condition in and of itself, but a sign or symptom of one. Once you have the medical problem under control, the nausea tends to get better as well, he says.

To get to the bottom of the exact cause of nausea, you need to pay attention to other discomfort you may be experiencing, such as a lack of appetite, cramping, diarrhea, pain in the back of the throat, sweating, lightheadedness, and vomiting. These could all be clues to the primary reason you feel like you’re going to throw up.

If nausea is a problem for you on the reg, it’s time to consider whether one of these common issues is the culprit.

Meet the experts: Caren Behar, MD, is a clinical professor in the department of medicine at NYU Grossman School of Medicine and the medical director of Joan H. Tisch Center for Women’s Health.

1. You’re taking pain meds.

Nausea is a common side effect of certain medications, but especially over-the-counter pain relievers or non-steroidal anti-inflammatory drugs, a.k.a. NSAIDs (think: aspirin, Motrin, Advil), says Caren Behar, MD, an internist at NYU Langone Health. “Anti-inflammatories are directly irritating to the stomach lining, and they can cause gastritis (inflammation) or ulcers,” she explains. “It’s like your stomach lining has a sunburn, so you can get nauseous or have vomiting, abdominal pain, or reflux.”

To help prevent this, always eat a snack before taking your meds since food coats your stomach lining (unless your doctor says otherwise), and limit your use of NSAIDs. “If you injure yourself, try to switch off between an anti-inflammatory and Tylenol because Tylenol is the only pain reliever that does not affect the stomach,” notes Dr. Behar.

If the stomach irritation is severe and nausea becomes unbearable, stop your meds entirely and talk with your doc about other pain relief options.

2. You are anxious.

It’s not fully understood why, but if you’re nervous or stressed (they usually go hand-in-hand), you may experience abdominal pain and nausea. “Our gastrointestinal tract has a very specific nervous system called the enteric nervous system, and it communicates directly with our central nervous system (brain and spinal cord),” Dr. Vanderheyden explains. “If a patient is stressed or anxious, nerves fire in the gut, and the body and brain will perceive it as nausea.”

And when your fight-or-flight response kicks in, a rush of hormones is released. These hormones then send chemical signals to the nerves in your gut, leading to nauseating contractions, according to Harvard Health.

There are lots of stress management strategies to choose from, but a healthy diet, plenty of sleep, drinking mint or ginger tea, meditating, yoga, journaling, and avoiding alcohol or tobacco are all easy ways to minimize anxiety and calm nausea, per the CDC. If you continually find yourself stressed to the point of feeling nauseous, talk with your doctor and consider working with a therapist to lower your overall stress levels.

3. You’re pregnant.

You’re familiar with morning sickness, but nausea is often one of the first signs of pregnancy and it can happen day or night. In fact, 75 percent of women are said to suffer from nausea and vomiting while pregnant, says Dr. Behar. “It usually begins within the first nine weeks of pregnancy, and if it begins later than that, a patient should be evaluated by their doctor,” she says. The nausea typically subsides around 14 weeks, but it can last longer.

And while nausea is normal and common during pregnancy due to fluctuating hormones, always talk with your ob-gyn before taking any medications. “We have to be careful with using drugs in pregnancy because it can affect the baby,” notes Dr. Behar.

Instead, try using ginger and increasing your vitamin B6 intake to soothe nausea. In rare cases, some women develop severe nausea and excessive vomiting, which can cause dehydration, also known as hyperemesis gravidarum. So, if you can’t keep anything down, talk with your ob-gyn ASAP, adds Dr. Behar.

4. You have a migraine.

If you suffer from migraines on a regular basis, you know nausea is one of the symptoms that usually accompanies the throbbing head pain. “One of the symptoms associated with migraine is nausea and vomiting, but [nausea] can also signal that a migraine is about to occur,” says Dr. Behar. This warning sign, a.k.a an aura, typically starts 30 minutes to an hour prior to an attack, but it can continue after the migraine sets in.

Other symptoms you may experience include blurry vision, ringing in the ears, flashes of light, and fatigue, says Dr. Ruiz.

You can try taking an OTC medication like Excedrin, Tylenol, and Advil to mitigate symptoms, but also make sure to stay hydrated and drink fluids because dehydration can make the nausea worse, adds Dr. Behar. If your migraines are chronic and frequently debilitating, it’s time to talk with your doctor about prescription medications or lifestyle changes.

5. You have food poisoning.

If you have an upset stomach along with cramps, diarrhea, nausea, vomiting, and a fever, you may have food poisoning, says Dr. Ruiz. It’s the body’s stress response to get rid of bacteria, viruses, and parasites that were in the food you ate.

Symptoms typically start a few hours after eating the contaminated food and generally last from a few hours to several days, says Dr. Ruiz. “If it’s going on for more than a day and you’re not able to keep even water down, then it’s time to seek medical care because you’re going to need IV fluids and anti-nausea medication,” he adds.

In addition, if you have bloody vomit or stool, severe abdominal pain, or extreme signs of dehydration like excessive thirst, dry mouth, lightheadedness, and fatigue, then it’s time to call a doctor, he adds.

6. You have gastroparesis.

Also known as delayed gastric emptying, gastroparesis is the slowing down or partial paralysis of your stomach muscles that prevents proper digestion, says Dr. Vanderheyden. Because of this, food sits in your stomach longer. Your stomach cannot accommodate new food and contracts when anything new enters the system, causing you to feel nauseous.

While most cases of gastroparesis are spontaneous, you’ll want to eat smaller, more frequent meals, so it’s easier on your stomach to pass and digest food, says Dr. Vanderheyden. That said, if you have extreme pain or severe nausea that is preventing you from eating, a trip to your doctor’s office is a must because you may be prescribed medications to help stimulate the stomach muscles and reduce nausea.

7. You have an ear infection.

This may surprise you, but ear infections could be the culprit. “The semicircular canals in the ear are one of the main components of balance in our body, and if you have inflammation in the canals, you may experience nausea and vomiting,” Dr. Behar explains.

This inflammation can be caused by bacteria, viruses, and a buildup of fluid in the ears that throws off your body’s ability to regulate itself and maintain balance, leaving you feeling nauseous and dizzy.

So, if you have ear pain or pressure accompanied by nausea or dizziness, check in with your doctor and they’ll likely prescribe an antibiotic to fight off the infection, adds Dr. Behar.

8. You get motion sickness.

Motion sickness is caused by any movement, but it’s usually associated with riding in a car, boat, or plane, says Dr. Behar. And similar to an ear infection, motion can cause an imbalance in the semicircular canals of your ear and can result in vertigo, nausea, and motion sickness.

Luckily, the nausea usually subsides once you are out of the moving vehicle, but if you are prone to motion sickness, you can take antihistamines before a trip like Dramamine, Zyrtec, and Claritin, says Dr. Behar.

9. You’re having a heart attack.

Women are more likely to experience other symptoms along with chest pain when having a heart attack, according to Mayo Clinic. If you have chest pressure that persists for minutes and you feel nauseous, go to the emergency room ASAP.

“You can have nausea, vomiting, shortness of breath, palpitations, and lightheadedness, which are all associated with cardiac causes,” says Dr. Behar. “It may just be reflux or heartburn, but you always have to rule out the worst.”

A heart attack is serious and needs to be checked out by a doctor. Your risk of having one is higher if you have high blood pressure, unhealthy cholesterol levels, diabetes, and obesity, per the CDC. It’s important to manage these conditions with medications and lifestyle changes so you can lower your likelihood of getting a heart attack.

10. You have a bacterial or viral infection.

If your nausea is accompanied by vomiting, congestion, fatigue, fever, diarrhea, abdominal cramping, or body aches, you may have a stomach bug, says Dr. Behar. You’ll likely need to go to the doc for an exact diagnosis, but the stomach flu, viral gastroenteritis, and COVID-19 all commonly present with nausea.

Unfortunately, stomach bugs usually have to run its course on its own, but anti-nausea medication can help and hydration (with electrolytes!) is key to a speedy recovery, says Dr. Behar. You’ll typically start to feel better after two days, but if you feel like you’re going to pass out, have bloody diarrhea, or your symptoms are getting worse, see a doctor immediately.

---

So, is there anything you can do to prevent nausea?

While nausea is sometimes inevitable (we’re looking at you, plane turbulence), there are a few things you can do to keep the queasiness at bay.

“The most important thing, believe it or not, is hydration and drinking a lot of fluids,” says Dr. Behar. Anytime you’re dehydrated you’re likely to feel nauseous, so women should always aim for about 11. 5 cups a day, according to Mayo Clinic.

And you’ll want to quit smoking since it’s directly associated with stomach inflammation, limit alcohol consumption, and minimize your use of anti-inflammatory meds, says Dr. Behar.

If you’re aware of specific triggers that make you nauseous such as certain scents, foods, or temperatures, do your best to avoid them whenever possible, notes Dr. Ruiz.

When should you see a doctor?

Some common causes of nausea may resolve on their own or with OTC medications and rest, but if your nausea affects your ability to go about your daily activities or you’re unable to function at work or at home, then it’s time to see a doctor.

“If you’re not yourself, and certainly if it’s been going on for more than four weeks, I would encourage someone to see their primary care provider,” says Dr. Vanderheyden

And if you are in extreme pain, constantly throwing up, have bloody stool, chest tightness, blurred vision, confusion, or other alarming symptoms, you need to go to the emergency room immediately.

7 unexpected and even dangerous causes of nausea

Likbez

Health

October 16, 2018

Perhaps brain problems or hepatitis are to blame.

There are dozens, if not hundreds, of causes of nausea. Among them are quite obvious: food poisoning, overeating (especially when it comes to fatty foods), exercising on a full stomach, hangovers, motion sickness, or toxicosis of the first trimester of pregnancy. But it happens that you feel sick, and because of what it is completely incomprehensible.

1. Acute stress

Tired before an exam or a serious conversation with the boss? This is completely normal. Fear, overexcitation, anxiety – all this can seem nauseous to our body.

This reaction is common in children and adolescents. Therefore, by the way, a children’s excuse from school or control – “Oh, my stomach hurts!” – often not an excuse at all.

But it often covers adults too. It all depends on the individual and the level of stress.

What to do with it . First of all, calm down. Breathe deeply. Take a walk. Maybe take valerian. Once the acute stress is removed, the nausea will subside.

2. Dehydration

Nausea is a common sign that the body is not getting enough fluid. As a rule, the second symptom in this case is dry mouth.

What to do with it . Drink a glass of cool water.

3. Diseases of the inner ear

In the inner ear, among other things, the vestibular apparatus is located. Any disorders of this part of the ear, such as labyrinthitis or Meniere’s disease, can cause the vestibular to fail.

The brain loses its orientation in space, which makes it seem as if the ground is moving out from under your feet. In order to stay upright, our body triggers reactions, some of which affect the vomiting center in the brain. And there is an attack of nausea.

What to do about it . If nausea is accompanied by dizziness and / or ear pain, hearing loss, noise, contact an otolaryngologist as soon as possible.

4. Mild concussion

Nausea is one of the most striking symptoms of traumatic brain injury. In general, a concussion is a very difficult thing to diagnose. It, as a rule, is detected not by analyzes and studies, but by the subjective complaints of patients.

So if you feel sick for no reason, try to remember if you hit your head today or yesterday. Perhaps they played football and made a pass with the top of their head? Or maybe, on a sharp turn, they hit the back of the head on the handrail or the temple on the wall of the minibus? Even the most insignificant, at first glance, blow can lead to a concussion.

What to do about it . If you did not lose consciousness on impact, then your possible concussion is most likely not dangerous. Just relax: lie down or sit in a comfortable chair, relax. In most cases, symptoms resolve within 15 to 30 minutes.

If the nausea, which could be caused by a stroke (especially if it was accompanied by a loss of consciousness), continues, go to a therapist. It is necessary! A concussion is fraught with serious complications.

5. Chronic traumatic brain injury

This is one of the consequences of ignored tremors. The fact is that brain injuries can have a cumulative effect. In some people, it is less pronounced (their brain removes toxins formed during injuries faster), in others it is more (they accumulate toxins and seriously affect brain function). Which category you belong to can only be determined by genetic analysis.

If you may have had regular head injuries in the past – for example, you are fond of extreme sports and have fallen, boxing, wrestling, took part in military operations – and at some point you began to feel bouts of nausea accompanied by fatigue and headache, it could be chronic traumatic brain injury.

What to do about it . Go to a neurologist. You will need to undergo a series of tests, possibly including different types of MRI.

6. Low blood pressure

Weakness, slight dizziness and nausea as the final chord are the key signs of a decrease in blood pressure.

What to do with it . Lie down and rest. You can drink a couple of glasses of water or eat something salty – these methods will slightly increase the volume of blood and help raise the pressure.

Fortunately, low blood pressure is rarely dangerous. However, it can impair the quality of life, so you should consult a therapist.

7. Viral hepatitis

Even before the icteric period, viral hepatitis is often manifested by a decrease in appetite and unmotivated (at first glance, naturally) nausea. A little later these symptoms are accompanied by itching of the skin, discomfort in the area of ​​the liver, sometimes fever…

What to do about it .
