Antibiotics are powerful medicines that can kill bacteria and help you feel better when you're sick. However, they can also cause diarrhea as a side effect. This is because antibiotics can disrupt the balance of good and bad bacteria in your gut.

How Antibiotics Work

Antibiotics work by killing bacteria. They can kill both bad bacteria that are causing an infection and good bacteria that help your body function properly.

The Role of Gut Bacteria

Your gut is home to trillions of bacteria, both good and bad. These bacteria play an important role in your health. They help you digest food, absorb nutrients, and fight off infection.

When you take antibiotics, they can kill both the bad bacteria that are causing your infection and the good bacteria in your gut. This can lead to an imbalance in your gut bacteria, which can cause diarrhea.

Other Causes of Diarrhea

There are other things that can cause diarrhea, such as:

• Eating contaminated food or water
• Viral infections
• Irritable bowel syndrome
• Inflammatory bowel disease

If you're experiencing diarrhea, it's important to see a doctor to rule out other possible causes.

What to Do if You Have Diarrhea

If you have diarrhea, there are a few things you can do to feel better:

• Drink plenty of fluids to stay hydrated.
• Eat bland foods, such as crackers, toast, and bananas.
• Avoid caffeine and alcohol.
• Take over-the-counter medications to relieve diarrhea, such as loperamide or bismuth subsalicylate.

If your diarrhea is severe or doesn't go away after a few days, see a doctor.

Preventing Diarrhea

There are a few things you can do to help prevent diarrhea while taking antibiotics:

• Eat yogurt or take probiotics. Probiotics are supplements that contain live bacteria that can help restore the balance of good bacteria in your gut.
• Eat foods that are high in fiber. Fiber can help keep your stool firm and prevent diarrhea.
• Drink plenty of fluids.

If you're concerned about diarrhea, talk to your doctor. They can help you manage this side effect of antibiotics.
