Nausea and Vomiting: Care Instructions

Overview

When you are nauseated, you may also feel weak and sweaty and notice a lot of saliva in your mouth. Nausea often leads to vomiting. Most of the time you do not need to worry about nausea and vomiting, but they can be signs of other illnesses.

Two common causes of nausea and vomiting are a stomach infection and food poisoning. Nausea and vomiting from a stomach infection will usually start to improve within 24 hours. Nausea and vomiting from food poisoning may last from 12 to 48 hours.

The doctor has checked you carefully, but problems can develop later. If you notice any problems or new symptoms, get medical treatment right away.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and contact your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

• To prevent dehydration, drink plenty of fluids. Choose water and other clear liquids until you feel better. If you have kidney, heart, or liver disease and have to limit fluids, talk with your doctor before you increase the amount of fluids you drink.
• Rest until you feel better.
• When you are able to eat, try clear soups, mild foods, and liquids until all symptoms are gone. Other good choices include dry toast, crackers, rice, cooked cereal, and gelatin dessert. Avoid high fat foods, spicy foods, and foods with a lot of sugar until you are well.
• Try peppermint tea, candy, or gum. For some people, peppermint helps an upset stomach.
