Nausea and Vomiting, Age 12 and Older
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).

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
Many things can affect how your body responds to a symptom and what kind of care you may need. These include:

- 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.

- Moderate: 100.4°F (38°C) to 103.9°F (39.9°C)
- Mild: 100.3°F (37.9°C) and lower
A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral 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)

Chest pain or pressure is the most common symptom, but some people, especially women, may not notice it as much as other symptoms. You may not have chest pain at all but instead have shortness of breath, nausea, or a strange feeling in your chest or other areas.
Symptoms of serious illness may include:
- A severe headache.

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, about1.5 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.
