What should you eat when you have diarrhea and gas?: A guide to soothing your digestive system

4 min read

According to the National Institutes of Health, over 179 million cases of acute diarrhea occur annually in the United States. For those who also experience uncomfortable gas, understanding what should you eat when you have diarrhea and gas can be crucial for a quicker recovery and minimizing distress.

Quick Summary

This nutritional guide explains which bland, low-fiber foods to eat when dealing with diarrhea and gas, emphasizes the importance of electrolyte-rich fluids, and identifies specific foods and drinks to avoid that can aggravate symptoms.

Key Points

  • Stay Hydrated: Drink plenty of clear liquids like water, broths, and electrolyte-rich fluids to prevent dehydration caused by diarrhea.

  • Eat Bland Foods: Opt for the low-fiber and easy-to-digest BRAT diet staples: bananas, white rice, applesauce, and white toast.

  • Introduce Lean Proteins: Gradually add bland, cooked proteins like baked chicken, fish, and soft eggs as you start to feel better.

  • Avoid Trigger Foods: Steer clear of fatty, greasy, spicy, and high-sugar foods, as well as those known to cause gas like beans and broccoli.

  • Exercise Caution with Dairy: Many become temporarily lactose intolerant during diarrhea, so limit or avoid milk and cheese, opting for low-lactose probiotic options like yogurt instead.

  • Reintroduce Gradually: After your symptoms subside, slowly bring back a wider variety of foods to avoid shocking your sensitive digestive system.

Prioritizing Hydration: The First and Most Crucial Step

When you have diarrhea, your body loses significant amounts of water and electrolytes, such as sodium and potassium. This can quickly lead to dehydration, which can be dangerous if left unchecked. Your first priority should always be to replenish these lost fluids. While plain water is good, it doesn't replace electrolytes. Consuming electrolyte-enhanced drinks or clear broths is highly recommended.

  • Clear Liquids: Sip on water, clear broths (chicken, beef, or vegetable), and diluted fruit juices (like apple juice, but avoid those with pulp).
  • Electrolyte-Rich Fluids: Sports drinks (choose lower-sugar options), coconut water, and oral rehydration solutions (like Pedialyte) are excellent for restoring lost minerals.
  • Room Temperature Drinks: Very hot or very cold liquids can sometimes irritate the stomach further. Aim for room temperature beverages.

The BRAT Diet and Other Bland Foods

For years, the BRAT diet has been a go-to recommendation for easing digestive upset. BRAT stands for Bananas, Rice, Applesauce, and Toast. These foods are low in fiber, bland, and easy to digest, helping to firm up stool. While a restrictive BRAT diet is not recommended for long-term use due to nutritional deficiencies, incorporating these foods is a good starting point.

Expanding on the BRAT Diet with Bland Additions

Once you tolerate the basic BRAT foods, you can gradually introduce other bland items that are gentle on the digestive system. Eating small, frequent meals throughout the day is often easier on the stomach than three large ones.

  • Lean Proteins: Baked or broiled skinless chicken, lean beef, fish, and soft-cooked eggs are easy on the stomach.
  • Low-Fiber Starches: Cream of wheat, white pasta, and plain crackers (like saltines) are easy to digest.
  • Soft Fruits and Vegetables: Peel and cook vegetables like carrots, potatoes, and zucchini until soft. Unsweetened canned fruits or cooked peeled pears are also gentle options.

Soothing the Digestive System with Probiotics

Probiotics are beneficial bacteria that can help restore a healthy balance to your gut microbiome, which can be disrupted by digestive illness. While research is ongoing, many find that probiotics can help shorten the duration of diarrhea.

  • Low-Lactose Yogurt or Kefir: These cultured dairy products contain live, active cultures. However, since many people experience temporary lactose intolerance during a bout of diarrhea, choose low-lactose or lactose-free options.
  • Fermented Soy Products: Miso and tempeh are good non-dairy sources of probiotics.

Comparison of Food Choices: Eat This, Not That

This table summarizes the best and worst food choices when dealing with digestive upset.

Foods to Eat Foods to Avoid
White rice Brown rice and whole grains
Bananas Citrus and high-fiber fruits
Unsweetened applesauce High-sugar juices
White toast Whole-wheat bread
Baked skinless chicken Fried, greasy, or fatty foods
Clear broths Fatty soups and sauces
Saltine crackers Spicy foods
Boiled potatoes Raw vegetables
Low-lactose yogurt High-fat dairy products
Herbal tea (decaf) Coffee, soda, and alcohol

Foods and Drinks to Avoid

Just as important as knowing what to eat is knowing what to avoid. Certain foods and drinks can irritate your digestive system, prolonging or worsening symptoms like gas and diarrhea.

  • High-Fiber Foods: Insoluble fiber, found in whole grains, nuts, and raw vegetables, can speed up digestion and worsen diarrhea.
  • Dairy Products (Caution): Many individuals become temporarily lactose intolerant when experiencing digestive distress. Most dairy, including milk, cheese, and ice cream, should be avoided, with some probiotic-rich exceptions.
  • Fatty and Fried Foods: Greasy, fatty, and fried foods are difficult for a sensitive stomach to process and can exacerbate symptoms.
  • Sugary Foods and Drinks: High-fructose corn syrup, artificial sweeteners (like sorbitol), and excessive sugar can worsen diarrhea and cause additional gas.
  • Gas-Inducing Vegetables: Foods like beans, broccoli, cabbage, and cauliflower can contribute to excess gas and bloating.
  • Caffeine and Alcohol: Both act as diuretics and can speed up gut motility, leading to further dehydration and irritation.
  • Spicy Foods: Spices can irritate the sensitive lining of the digestive tract.

When to Seek Medical Attention

While dietary changes are often effective for mild, short-term diarrhea, you should consult a doctor if your symptoms are severe or persist. Seek medical attention if you experience signs of dehydration, high fever, or blood in your stool. For more detailed information on managing symptoms, consult authoritative medical resources like the Mayo Clinic.

Conclusion: A Gentle Path to Recovery

When your digestive system is distressed by diarrhea and gas, a strategic dietary approach is key to recovery. Begin with the basics: focus on staying hydrated with clear, electrolyte-rich fluids. Introduce bland, low-fiber foods like the BRAT diet staples and lean proteins gradually. By avoiding common culprits like high-fat, sugary, spicy, and gas-inducing foods, you can minimize irritation and help your system return to normal more quickly. As you feel better, you can slowly reintroduce a broader range of foods while continuing to prioritize gut health with probiotics.

Frequently Asked Questions

The BRAT diet consists of Bananas, Rice, Applesauce, and Toast. These foods are bland, low in fiber, and easy to digest, which can help firm up stool. While effective for short-term relief, doctors now recommend a slightly more varied bland diet, as the BRAT diet is restrictive and lacks essential nutrients for prolonged periods.

You should generally avoid milk and most dairy products when experiencing digestive distress. Many people become temporarily lactose intolerant during diarrhea, and the fats in dairy can aggravate symptoms. Some exceptions include low-lactose or lactose-free yogurt and kefir, which contain beneficial probiotics.

The best drinks are those that replenish both fluids and electrolytes. Plain water is essential, but also consider clear broths, diluted apple juice, sports drinks with lower sugar content, coconut water, or oral rehydration solutions.

Avoid gas-inducing vegetables like beans, broccoli, cauliflower, cabbage, and raw vegetables. When introducing vegetables, opt for cooked, peeled, and seeded varieties like carrots, potatoes, and green beans.

Fatty, greasy, and fried foods are difficult for the sensitive digestive system to process. The extra fat can be broken down in the large intestine, releasing extra fluids that can worsen diarrhea.

Probiotics, which are beneficial bacteria, can help restore a healthy balance to your gut microbiome. This can sometimes shorten the duration of diarrhea. You can find probiotics in foods like low-lactose yogurt and kefir or take a supplement after consulting a doctor.

High-fiber foods, especially those with insoluble fiber (like whole grains, nuts, and raw vegetables), can stimulate bowel movements and make diarrhea worse. It's best to stick to low-fiber, bland foods during a flare-up.
