Self-Care for Vomiting and Diarrhea

Vomiting and diarrhea can make you miserable. Your stomach and bowels are reacting to an irritant. This might be food, medicine, or viral stomach flu. Vomiting and diarrhea are two ways your body can remove the problem from your system. Nausea is a symptom that discourages you from eating. This gives your stomach and bowels time to recover. To get back to normal, start with self-care to ease your discomfort.

Drink liquids

Drink or sip liquids to avoid losing too much fluid (dehydration):

  • Clear liquids such as water or broth are the best choices.

  • Do not drink beverages with a lot of sugar in them, such as juices and sodas. These can make diarrhea worse.

  • If you have severe vomiting, do not drink sport drinks, such as electrolyte solutions. These don't have the right mix of water, sugar, and minerals. They can also make the symptoms worse. In this situation, commercially available oral rehydration solutions are best. 

  • Suck on ice chips if the thought of drinking something makes you queasy.

When you’re able to eat again

Tips include the following:

  • As your appetite comes back, you can resume your normal diet.

  • Ask your healthcare provider whether you should stay away from any foods.


Know the following about medicines:

  • Vomiting and diarrhea are ways your body uses to rid itself of harmful substances such as bacteria. DO NOT use antidiarrheal or antivomiting (antiemetic) medicines unless your healthcare provider tells you to do so.

  • Aspirin, medicine with aspirin, and many aspirin substitutes can irritate your stomach. So avoid them when you have stomach upset.

  • Certain prescription and over-the-counter medicines can cause vomiting and diarrhea. Talk with your healthcare provider about any medicines you take that may be causing these symptoms.

  • Certain over-the-counter antihistamines can help control nausea. Other medicines can help soothe stomach upset. Ask your healthcare provider which medicines may help you.
