Vomiting and diarrhea can make you feel awful. Your stomach and bowels are reacting to an irritant. This might be food, medicine, bacteria, or a virus. Vomiting and diarrhea are two ways your body tries to remove the problem from your system. Nausea is a symptom that prevents you from eating. This can give your stomach and bowels time to recover. Self-care can help ease your discomfort.

Drink or sip liquids. This is so you don't lose too much fluid (dehydration). To do this:

• Choose clear liquids, such as water or broth.
• Don't have drinks with a lot of sugar in them. This includes juice and soda. These can make diarrhea worse.
• Don't have drinks with caffeine and alcohol.
• If you have severe vomiting or diarrhea, don't drink sports drinks or electrolyte drinks. These don't have the right mix of water, sugar, and minerals. They can make the symptoms worse. Try an oral rehydration solution.
• Suck on ice chips if nausea makes it hard for you to drink.

Try these tips:

• As nausea eases and your appetite comes back, slowly go back to your normal diet.
• Ask your doctor if you should not eat certain foods.

When considering medicines:

• Don't use medicines to stop diarrhea or vomiting unless your doctor tells you to do so. Vomiting and diarrhea can help your body get rid of harmful substances.
• Some medicines can cause vomiting and diarrhea. Talk with your doctor about all medicines you take. Ask which ones may cause these symptoms.
• Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) can bother your stomach. Don't use them when you have an upset stomach.
• Some over-the-counter medicines can help control nausea. Others can help soothe an upset stomach. Ask your doctor which medicines may help you.
