What is diarrhea vs. dysentery?
Diarrhea and dysentery are conditions that affect your internal digestive and waste disposal system. Diarrhea is a loose, liquid stool discharged from your rectum when you go to the bathroom. It is a very common condition and can be caused by several things. Dysentery, contrary to popular belief, isn’t caused by viruses. It is a progressive symptom of bacterial diarrhea.

It is essential to know the differences and symptoms so you know when to call the doctor. You can treat diarrhea at home, but you shouldn't try to treat dysentery on your own. Because it is a bacterial infection, it requires medicine for treatment.

Diagnosing dysentery is similar to diarrhea, but the doctor will take a sample of your stool and test it for bacteria.
Treatments for diarrhea vs. dysentery
To treat diarrhea and dysentery, doctors take different approaches. You can treat diarrhea by drinking lots of fluids and eating solid foods. You’ll need to build your electrolytes back up, so the doctor might tell you to drink some rehydrating sports drinks or Pedialyte.
Treatments for diarrhea
If you have diarrhea, doctors recommend eating normally when your appetite returns, if you’ve lost it. Avoid the following foods and beverages when returning to your regular diet so that diarrhea doesn’t come back:
- Alcoholic drinks
- Drinks, foods, or supplements that contain caffeine
- Milk, ice cream, or other dairy product
- Fast, greasy, or spicy foods
- Fruit juices
- Pears, apples, and peaches
- Drinks, snacks, or sweets with artificial sweeteners like mannitol, sorbitol, and xylitol
Treatments for dysentery
If you have dysentery, the doctor will prescribe antibiotics such as ciprofloxacin or azithromycin to treat the intestinal infection.
Along with the antibiotics, the doctor will want you to drink a generous amount of fluids to flush your system and build your electrolytes up. Similar to treatments for diarrhea, Pedialyte or rehydrating sports drinks will work, as will eating solid foods.
Untreated, both conditions can be life-threatening. Severe dehydration can occur if you don’t see a doctor in time or if your diarrhea persists and won’t go away. If you experience any dysentery symptoms or have diarrhea that doesn’t go away, see your doctor immediately.
