Overview
Nausea is a sick feeling in the pit of your stomach. When you are nauseated, you may feel weak and sweaty. You may 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 aren't serious. Home treatment will often help you feel better.
Nausea and vomiting can be a symptom of another illness. They may be 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.
- A migraine headache.
- A heart attack.
- A head injury.
- Alcohol or drug abuse or 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.
- An infection in or around the brain, such as meningitis, encephalitis, or a brain tumor.
Nausea and vomiting can quickly cause dehydration. Older adults are more likely to get dehydrated.
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, such as blood thinners (anticoagulants), medicines that suppress the immune system like steroids or chemotherapy, herbal remedies, or 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.

Self-Care
Here are some things you can do at home to treat occasional nausea and vomiting.
- 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 get dehydrated.
- Be careful with medicines.
- 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. Read and follow all instructions on the label.
- 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. It can help decrease the stomach contractions that may be causing your nausea.
- Take it easy and stay hydrated if you are vomiting.
- Rest in bed until you feel 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. Don't drink milk products, alcohol, or fizzy drinks such as sodas.
- If you don't have any more vomiting, increase the amount of fluid you drink to 8 fl oz (240 mL) during the second hour. If you aren't vomiting after the second hour, make sure that you keep drinking enough to prevent dehydration.
- When you feel better, start to eat 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. They can make nausea worse.
- Rinse your mouth with water after you vomit.
Brush your teeth if you can. The acid in vomit can erode dental enamel and cause tooth decay (cavities).
When to call for help during self-care
Call a doctor if any of the following occur during self-care at home:
- New or worse dehydration.
- Severe vomiting.
- New or worse belly pain.
