Most cases of diarrhea don’t require any medical treatment or diagnosis unless it’s severe. Once you visit your doctor, they will ask you about what you have been recently eating and drinking, your medical history, and the medicines you have been consuming.

They could recommend certain tests to determine the cause of your diarrhea, and those tests include:

  • Stool tests to check if your diarrhea is being caused by parasites or bacteria.
  • Hydrogen breath test to look for bacterial overgrowth and fructose or lactose intolerance.

  • A colonoscopy to check for the presence of intestinal disease.

How to Treat Diarrhea at Home?

How to Treat Diarrhea at Home

When your diarrhea is not too severe, it is possible to treat it at home. The first aid for diarrhea is as follows:

  • Consume plenty of water along with other electrolyte-balanced fluids. The latter includes sports drinks, broths, pulp-free and diluted fruit juices, and caffeine-free sodas. These beverages aid in replacing the water and electrolytes your body loses during diarrhea.
  • Eat foods that help in firming up your stool. Low-fiber foods are the best for this purpose. Following the BRAT diet is beneficial when you have diarrhea. This diet calls for you to have bananas [B], white rice [R], applesauce [A], and toast [T]. Other good food options include lean beef, noodles, potatoes, and turkey or chicken, or fish without the skin. Bringing about changes in your daily diet can do wonders in providing relief to your body during diarrhea.
  • Stay away from foods and drinks that cause you gas. Carbonated beverages, brussels sprouts, beer, cabbage, and beans come under this category as they could give you stomach cramps. Diarrhea can also cause a person to become temporarily lactose intolerant. Therefore, it’s best to stay away from dairy products till your diarrhea gets cured.
  • Avoid alcohol and caffeine as alcohol can cause dehydration and caffeinated drinks and foods can lead to a mild laxative effect which worsens a person’s diarrhea. It’s vital to stay away from chocolate, green tea, strong tea, sodas, and coffee.
  • Over-the-counter antidiarrheal medications are often useful when you have diarrhea. These include loperamide and bismuth subsalicylate. They help in bringing the symptoms under control and can also reduce the number of watery stools. However, it’s imperative that you talk to your doctor before consuming these medicines or giving them to your children.
  • You could consider taking probiotics. They boost the level of good bacteria and aid in restoring a healthy balance to a person’s intestinal tract. Much like the antidiarrheal medications, it’s vital that you consult your doctor before taking probiotics. These are usually available in the form of liquids or capsules and are often added to certain food items.

When to See a Doctor for Diarrhea?

If you have diarrhea, you should contact your doctor under the following circumstances:

  • In case your diarrhea lasts for longer than two days.

  • If you have a fever that’s higher than 39 degrees Celsius.
