Diarrhea: Care Instructions

Overview

Diarrhea is loose, watery stools (bowel movements). The exact cause is often hard to find. Sometimes diarrhea is your body's way of getting rid of what caused an upset stomach. Viruses, foodborne illness, and many medicines can cause diarrhea. Some people get diarrhea in response to emotional stress, anxiety, or certain foods.

Almost everyone has diarrhea now and then. It usually isn't serious, and your stools will return to normal soon. The important thing to do is replace the fluids you have lost, so you can prevent dehydration.

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 call your doctor or nurse advice line (811 in most provinces and territories) 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?

  • Watch for signs of dehydration, which means your body has lost too much water. Dehydration is a serious condition and should be treated right away. Signs of dehydration are:
    • Increasing thirst and dry eyes and mouth.
    • Feeling faint or light-headed.
    • A smaller amount of urine than normal.
  • 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.
  • When you feel like eating, start with small amounts of food.
  • The doctor may recommend that you take over-the-counter medicine, such as loperamide (Imodium). Read and follow all instructions on the label. Do not use this medicine if you have bloody diarrhea, a high fever, or other signs of serious illness. Call your doctor or nurse advice line if you think you are having a problem with your medicine.
