Top of the pageCheck Your Symptoms
Nausea is a sick feeling in the pit of your stomach. When you are nauseated, you may feel weak and sweaty and have too much saliva in your mouth. You may even vomit. This forces your stomach contents up your esophagus and out of your mouth. Most of the time, nausea and vomiting are not serious. Home treatment will often help you feel better.
Nausea and vomiting can be a symptom of another illness. Nausea and vomiting may be caused by:
- Illness caused by a virus, such as viral stomach illness (gastroenteritis).
- Food poisoning.
- Medicines, such as antibiotics, birth control pills, or heart medicines.
- Pregnancy. "Morning sickness" may be one of your first symptoms.
- Problems with abdominal (belly) organs.
- Migraine headache.
- Heart attack.
- Head injury.
- Alcohol and drug use. Or problems caused by quitting their use (withdrawal).
- Eating disorders, such as anorexia or bulimia.
- Disorders of the inner ear, such as labyrinthitis, Ménière's disease, or motion sickness.
- Radiation therapy.
Nausea or vomiting also may be a symptom of a problem or a disease, such as:
- Liver disease (hepatitis or cirrhosis).
- Inflammation of the pancreas (pancreatitis).
- Inflammation or irritation of the lining of the stomach (gastritis).
- Ulcer disease of the stomach or small intestine (peptic ulcers).
- Gallbladder problems (cholecystitis).
- Inflammation of the appendix (appendicitis).
- Kidney stones.
- Kidney disease (pyelonephritis or chronic kidney disease).
- Urinary problems, such as a urinary tract infection (UTI).
- Bowel problems, such as a bowel obstruction.
- Infection in or around the brain, such as meningitis, encephalitis, or a brain tumor.
Nausea and vomiting can quickly cause dehydration. Older adults have an increased chance of becoming dehydrated.
Check your symptoms to decide if and when you should see a doctor.
Check Your Symptoms
The medical assessment of symptoms is based on the body parts you have.
- If you are transgender or nonbinary, choose the sex that matches the body parts (such as ovaries, testes, prostate, breasts, penis, or vagina) you now have in the area where you are having symptoms.
- If your symptoms aren’t related to those organs, you can choose the gender you identify with.
- If you have some organs of both sexes, you may need to go through this triage tool twice (once as "male" and once as "female"). This will make sure that the tool asks the right questions for you.
Many things can affect how your body responds to a symptom and what kind of care you may need. These include:
- Your age. Babies and older adults tend to get sicker quicker.
- Your overall health. If you have a condition such as diabetes, HIV, cancer, or heart disease, you may need to pay closer attention to certain symptoms and seek care sooner.
- Medicines you take. Certain medicines, herbal remedies, and supplements can cause symptoms or make them worse.
- Recent health events, such as surgery or injury. These kinds of events can cause symptoms afterwards or make them more serious.
- Your health habits and lifestyle, such as eating and exercise habits, smoking, alcohol or drug use, sexual history, and travel.
Try Home Treatment
You have answered all the questions. Based on your answers, you may be able to take care of this problem at home.
- Try home treatment to relieve the symptoms.
- Call your doctor if symptoms get worse or you have any concerns (for example, if symptoms are not getting better as you would expect). You may need care sooner.
An illness plan for people with diabetes usually covers things like:
- How often to test blood sugar and what the target range is.
- Whether and how to adjust the dose and timing of insulin or other diabetes medicines.
- What to do if you have trouble keeping food or fluids down.
- When to call your doctor.
The plan is designed to help keep your diabetes in control even though you are sick. When you have diabetes, even a minor illness can cause problems.
It is easy for your diabetes to become out of control when you are sick. Because of an illness:
- Your blood sugar may be too high or too low.
- You may not be able take your diabetes medicine (if you are vomiting or having trouble keeping food or fluids down).
- You may not know how to adjust the timing or dose of your diabetes medicine.
- You may not be eating enough or drinking enough fluids.
Temperature varies a little depending on how you measure it. For adults and children age 12 and older, these are the ranges for high, moderate, and mild, according to how you took the temperature.

Ear or rectal temperature
- High: 105°F (40.6°C) and higher
- Moderate: 101.4°F (38.6°C) to 104.9°F (40.5°C)

Home treatment may be all that is needed to treat occasional nausea.
- Watch for dehydration, and treat it early. Signs of dehydration include being thirstier than usual and having less urine than usual. Older adults and young children can quickly become dehydrated.
- Don't use aspirin or a nonsteroidal anti-inflammatory drug (NSAID), such as ibuprofen, to treat belly pain.
- Take an over-the-counter antinausea medicine, such as meclizine (Antivert or Bonine) or dimenhydrinate (Dramamine), or an antihistamine, such as Benadryl. Don't give antihistamines to your child unless you've checked with the doctor first.
- Try acupressure:
- Place the tip of your right index finger on the underside of your left wrist, about 1.5 in. (4 cm) from your hand. Acupressure points are very small, so you may need to try this method more than one time.
- Apply moderate pressure for 2 to 3 minutes.
- Repeat as needed.
- Acupressure bands, which are available for motion sickness, may help reduce nausea.
- Suck on peppermint candy, or chew a stick of peppermint gum. Peppermint may relax tight muscles in your stomach and help decrease the stomach contractions that may be causing your nausea.
If you are vomiting:
- Rest in bed until you are feeling better.
- Sip a rehydration drink to restore lost fluids and nutrients.
- After vomiting has stopped for 1 hour, drink 1 fl oz (30 mL) of a clear liquid every 20 minutes for 1 hour. Clear liquids include apple or grape juice mixed to half strength with water, rehydration drinks, weak tea with sugar, clear broth, and gelatin dessert. Avoid orange juice, grapefruit juice, tomato juice, and lemonade. Avoid apple and grape juice if you also have diarrhea. Do not drink milk products, alcohol, or carbonated drinks such as sodas.
- If you do not have any more vomiting, increase the amount of fluid you drink to 8 fl oz (240 mL) during the second hour. If you are not vomiting after the second hour, make sure that you continue to drink enough to prevent dehydration.
- When you are feeling better, begin eating clear soups, mild foods, and liquids until all symptoms are gone for 12 to 48 hours. Gelatin dessert, dry toast, crackers, and cooked cereal are good choices. Try to stay away from strong food odors, which can make nausea worse.
The acid in vomit can erode dental enamel and cause tooth decay (cavities). Rinse your mouth with water after you vomit. Brush your teeth if you can.
Symptoms to watch for during home treatment
Call your doctor if any of the following occur during home treatment:
- Dehydration develops. Signs of dehydration include being thirstier than usual and having less urine than usual.
- A stiff neck develops.
- Severe vomiting develops.
- Vomit contains blood or material that looks like coffee grounds.
- Vomiting with fever of 103°F (39.4°C) or higher occurs or fever lasts longer than 2 days.
- Belly pain develops or gets worse.
- Your symptoms become more severe or more frequent.
Food poisoning is one of the most common causes of nausea and vomiting in adults. To prevent food poisoning:
- Follow the 2-40-140 rule. Don't eat meats, dressing, salads, or other foods that have been kept between 40°F (4.4°C) and 140°F (60°C) for more than 2 hours.
- Be especially careful with large cooked meats, such as your holiday turkey, which require a long time to cool. Thick parts of the meat may stay over 40°F (4.4°C) long enough to allow bacteria to grow.
- Use a thermometer to check your refrigerator. It should be between 34°F (1.1°C) and 40°F (4.4°C).
- Defrost meats in the refrigerator or the microwave, not on the kitchen counter.
- Wash your hands, cutting boards, and countertops often. After handling raw meats, especially chicken, wash your hands and utensils before preparing other foods.
- The U.S. Department of Agriculture (USDA) recommends that you reheat meats to over 140°F (60°C) for at least 10 minutes to destroy bacteria. Even then the bacteria may not be destroyed.
- Cook all meats to the recommended temperature. See how to cook foods to prevent food poisoning.
- Cook hamburger well done. Cook chicken until the juices run clear.
- Cover meats and poultry during microwave cooking to heat the surface of the meat.
- Do not eat raw eggs or uncooked sauces made with eggs.
- Keep party foods on ice.
- When you eat out, avoid rare and uncooked meats or seafood. Eat salad bar and deli items before they get warm.
- Discard any cans or jars with bulging lids or leaks.
- Follow home canning and freezing instructions carefully. Contact your county agricultural extension office for advice.
- If you think that food may have been stored in your refrigerator for too long, don't take the chance. Throw it out.
For more information, see the topic Food Poisoning and Safe Food Handling.
Increase your chance of staying healthy by:
- Washing your hands often, especially during winter months when viral illnesses are most common.
- Keeping your hands away from your nose, eyes, and mouth. Viruses are most likely to enter your body through these areas.
- Eating a healthy and balanced diet.
- Getting regular exercise.
- Not smoking. Smoking irritates the lining of your nose, sinuses, and lungs, which may increase your risk for problems from a viral illness.
