What is the best thing to eat after having diarrhea?

4 min read

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), most cases of acute diarrhea last only a couple of days. When recovering, knowing what is the best thing to eat after having diarrhea is crucial for rehydration and avoiding further stomach upset.

Quick Summary

The most effective dietary approach involves rehydrating immediately and then reintroducing bland, easily digestible foods. Prioritize electrolyte-rich fluids and low-fiber, low-fat foods to soothe the digestive system and promote firmer stools.

Key Points

  • Start with Rehydration: Immediately replace lost fluids and electrolytes with oral rehydration solutions, clear broths, or water.

  • Follow the BRAT Diet: Start with bland, binding foods like bananas, rice, applesauce, and toast to firm up stools and be gentle on your stomach.

  • Avoid Irritating Foods: Temporarily cut out high-fiber, fatty, spicy, and sugary items, as well as caffeine and alcohol.

  • Reintroduce Foods Slowly: Gradually add more complex, low-fat foods after a couple of days of a bland diet, paying attention to how your body reacts.

  • Consider Probiotics: Plain yogurt or other probiotic-rich foods can help restore healthy gut bacteria, but be mindful of lactose intolerance.

  • Eat Small, Frequent Meals: Opt for several small meals throughout the day rather than a few large ones to ease the burden on your digestive system.

  • Listen to Your Body: If symptoms worsen with any new food, return to the bland diet and fluids.

Prioritizing Fluids and Electrolytes

Immediately following a bout of diarrhea, your primary focus should be rehydration. The loss of water and essential minerals, or electrolytes, is a significant concern that can lead to complications.

  • Oral Rehydration Solutions (ORS): These specially formulated drinks, like Pedialyte, contain a balanced mix of water, salts, and sugar to effectively replenish lost electrolytes.
  • Clear Broths: Chicken, vegetable, or beef broth (clear and non-greasy) can help replace sodium and provide hydration.
  • Coconut Water: A natural source of electrolytes, coconut water is a great alternative to commercial sports drinks, which can be high in sugar.
  • Sports Drinks: While some commercial sports drinks are high in sugar, some can be used to restore electrolytes. Diluting them with water can be helpful.
  • Water: Plain water is always a good choice, but it's important to supplement with electrolyte-rich fluids, as water alone doesn't replace lost minerals.

The BRAT Diet and Other Bland Foods

After you've successfully rehydrated and your appetite returns, you can gradually introduce simple, bland foods. The well-known BRAT diet is a great starting point. The acronym stands for Bananas, Rice, Applesauce, and Toast. These foods are low in fiber, which helps bind the stool, and are easy on the digestive system.

Foods to Include in a Bland Diet:

  • Bananas: High in potassium and pectin (a soluble fiber) which helps firm stools.
  • Plain White Rice: Easy to digest and helps bind stools.
  • Applesauce: A simple, low-fiber source of pectin.
  • Toast: Made from plain white bread, which is easier to digest than whole-grain versions.
  • Boiled Potatoes: Peeled and plain, they offer potassium and are gentle on the stomach.
  • Plain Crackers: Saltine crackers or similar unseasoned varieties are excellent for snacking.
  • Cooked Cereal: Oatmeal or Cream of Wheat are good, low-fiber options.
  • Lean Protein: Baked or steamed skinless chicken and boiled eggs are good sources of protein once you are feeling a bit better.

Foods to Avoid to Prevent Relapse

Just as important as knowing what to eat is knowing what to avoid. Certain foods can aggravate your digestive system and prolong your recovery.

Foods to Exclude Temporarily:

  • High-Fiber Foods: While generally healthy, high-fiber foods like whole grains, beans, and certain raw vegetables can worsen diarrhea.
  • Fatty and Greasy Foods: Fried foods, burgers, and other fatty items are difficult for a compromised digestive system to process.
  • Dairy Products (with exceptions): Milk, cheese, and butter contain lactose, which can be hard to digest temporarily. Probiotic-rich yogurt or kefir, however, may be tolerated and beneficial.
  • Spicy and Highly Seasoned Foods: These can irritate the stomach lining.
  • Sugary Foods and Drinks: Excess sugar, including high-fructose corn syrup and artificial sweeteners, can pull water into the colon and worsen diarrhea.
  • Caffeine and Alcohol: Both can act as diuretics and dehydrate you further, and they can also stimulate the digestive tract.

Comparison Table: Good vs. Bad Foods

To help you make the right choices, here is a quick guide comparing what to eat and what to avoid.

Foods to Eat (Good) Foods to Avoid (Bad)
Bananas Citrus Fruits (Oranges, Grapefruits)
Plain White Rice Whole Grains
Unsweetened Applesauce Fried or Fatty Foods
Plain White Toast Spicy or Highly Seasoned Foods
Clear Broths Most Dairy Products
Boiled Potatoes Alcohol and Caffeine
Plain Crackers Sugary Drinks and Artificial Sweeteners
Lean, Skinless Chicken Beans, Legumes, and High-Fiber Vegetables

Reintroducing a Normal Diet

Once you feel better, you can start reintroducing other foods slowly. Start with soft, cooked vegetables and lean meats. Pay close attention to how your body reacts to each new food. After a few days of feeling stable, you can resume a more normal, balanced diet. Small, frequent meals are often easier to tolerate than large ones.

Conclusion

Recovering from diarrhea is a phased process that prioritizes rehydration, restoring electrolytes, and gradually reintroducing simple, bland foods. Beginning with clear fluids and following the principles of the BRAT diet can significantly aid your recovery and soothe your digestive system. It is vital to avoid irritating foods and drinks to prevent a relapse. By listening to your body and taking a step-by-step approach, you can get back to your normal eating habits with minimal discomfort. If symptoms persist for more than a few days, or if you experience signs of severe dehydration, it is always best to consult a healthcare professional for guidance.

Importance of Probiotics

In addition to dietary changes, probiotics can be beneficial. These live microorganisms can help restore the healthy balance of bacteria in your gut, which is often disrupted by diarrhea. Plain, low-sugar yogurt and kefir are good sources of probiotics that may be tolerated, though some people may need to avoid dairy initially.

Gradual Reintroduction

When transitioning back to your regular diet, think in stages. After a day or two of the bland BRAT diet, you can start to add low-fat, low-fiber foods. This might include plain pasta, cooked carrots, and oatmeal. This gradual approach helps ensure your digestive system doesn't get overwhelmed and allows you to identify any lingering sensitivities. Consistent monitoring of your symptoms is key throughout this process.

Frequently Asked Questions

The BRAT diet (bananas, rice, applesauce, and toast) is recommended because these foods are low in fiber, easy to digest, and can help bind stools due to their starchy nature.

To prevent dehydration, drink plenty of fluids, including water, clear broths, and electrolyte-enhanced drinks like oral rehydration solutions or coconut water.

Most dairy products should be avoided initially, as lactose can be difficult to digest. However, plain yogurt and kefir, which contain probiotics, may be tolerated and beneficial for restoring gut bacteria.

You can gradually start reintroducing more foods once your diarrhea has stopped and you feel better, typically after a couple of days of a bland diet. Reintroduce one food at a time to monitor your tolerance.

You should avoid high-fiber, gas-producing foods initially. However, soluble fiber found in bananas and applesauce is beneficial. You can reintroduce other fiber sources gradually as you recover.

If you are unable to keep any fluids or foods down, you should contact a healthcare provider. Persistent vomiting can lead to severe dehydration and requires medical attention.

No, you should avoid coffee, other caffeinated drinks, and alcohol, as they can have a diuretic effect and further dehydrate your body, and can also irritate your digestive system.
