In most cases of diarrhea, replacing lost fluid to prevent dehydration is the only treatment necessary. Medicines that stop diarrhea may be helpful, but they are not recommended for people whose diarrhea is caused by a bacterial infection or parasite. If you stop the diarrhea before having purged the bacteria or parasite, you will trap the organism in the intestines and prolong the problem. Rather, doctors usually prescribe antibiotics as a first-line treatment. Viral infections are either treated with medication or left to run their course, depending on the severity and type of virus.
Tips About Food
Until diarrhea subsides, try to avoid caffeine, milk products, and foods that are greasy, high in fiber, or very sweet. These foods tend to aggravate diarrhea.
As you improve, you can add soft, bland foods to your diet, including bananas, plain rice, boiled potatoes, toast, crackers, cooked carrots, and baked chicken without the skin or fat. For children, the pediatrician may also recommend a bland diet. Once the diarrhea has stopped, the pediatrician will likely encourage children to return to a normal and healthy diet if it can be tolerated.
Preventing Traveler’s Diarrhea
Traveler’s diarrhea happens when you consume food or water contaminated with bacteria, viruses, or parasites. You can take the following precautions to prevent traveler’s diarrhea when you travel outside of the United States:
You can safely drink bottled water—if you are the one to break the seal—along with carbonated soft drinks, and hot drinks such as coffee or tea.
Depending on where you are going and how long you will stay, your doctor may recommend that you take antibiotics before leaving to protect you from possible infection.
