At some point in your pregnancy, you may have diarrhea. Generally, it is brought on by gastrointestinal bacteria that you either picked up from someone else or contracted by eating spoiled food. These cases rarely last more than 72 hours.
Although it's a lousy way to spend a Sunday, you're better off letting diarrhea run its course than trying to stop it. It may worry you if the food you eat passes right through your body. However, missing out on nutrition for a couple of days isn't going to hurt you or your baby. The most important thing is to keep replenishing your fluids with clear liquids such as water, chicken broth, or juices.
If you have a severe or prolonged case of diarrhea, diarrhea accompanied by a fever, or stools that look bloody or contain mucus, contact your health care provider. Your provider may check you for other infections and parasites, especially if you've been around people with other serious illnesses or if you've traveled someplace (such as a foreign country) where the water isn't considered potable. If you are very dehydrated, you may be treated with an IV, and your doctor may suggest an antidiarrheal medication.
