A Guide on What Should I Eat if I Have Gastric and Diarrhea?

4 min read

According to research, proper dietary adjustments can help manage and alleviate the symptoms of both gastritis (inflammation of the stomach lining) and diarrhea. Choosing the right foods is crucial for giving your digestive system a rest and promoting recovery, so what should I eat if I have gastric and diarrhea?. This guide provides a detailed breakdown of the best nutritional approaches to help you feel better.

Quick Summary

This guide outlines dietary strategies for managing gastritis and diarrhea simultaneously. It emphasizes consuming bland, easy-to-digest foods like the BRAT diet, focusing on proper hydration with electrolytes, and gradually reintroducing a balanced diet. Key foods to avoid include fatty, spicy, and high-fiber items, along with caffeine and alcohol.

Key Points

  • Start with clear fluids: Prioritize water and oral rehydration solutions to prevent dehydration from diarrhea.

  • Embrace bland foods: Follow a simple, low-fiber diet like the BRAT diet (bananas, rice, applesauce, toast) to soothe your stomach and firm stools.

  • Steer clear of irritants: Avoid spicy, acidic, fatty, and high-fiber foods, as well as caffeine and alcohol, to prevent aggravating gastric symptoms.

  • Consider probiotics: Introduce low-fat yogurt or kefir with live cultures as tolerated to help restore good gut bacteria.

  • Eat small, frequent meals: Opt for smaller portions throughout the day to avoid overwhelming your digestive system.

  • Reintroduce foods gradually: Slowly add more variety back into your diet after symptoms improve to ensure continued tolerance.

Prioritizing Hydration and Rest for Recovery

When dealing with both gastritis and diarrhea, the top priority is preventing dehydration. Diarrhea causes your body to lose significant fluids and electrolytes, which must be replenished. In the initial stages, your appetite may be low, but staying hydrated is non-negotiable.

Oral Rehydration Solutions

  • Water: Plain water is the best and most basic fluid for hydration.
  • Oral Rehydration Solutions (ORS): These contain specific ratios of salts and sugars to help the body absorb fluids more effectively than water alone. They are especially important for children, older adults, and those with weakened immune systems.
  • Broths: Clear vegetable or chicken broth can help replace lost sodium.
  • Coconut water: A natural source of electrolytes, but choose a variety low in added sugar.

The Healing Power of a Bland Diet

A bland diet is central to recovery, as it consists of foods that are soft, low in fiber, and not spicy, helping to prevent irritation of the stomach lining and intestines. The well-known BRAT diet is a solid starting point for its binding and easy-to-digest properties.

Foundational Bland Foods

  • Bananas: Rich in potassium to replace lost electrolytes and act as a binding agent to firm up stool.
  • White Rice: Plain, cooked white rice is low in fiber and easily digestible.
  • Applesauce: A better choice than raw apples, as the skin is removed and the cooked fruit contains pectin, a soluble fiber that helps bind stool.
  • White Toast: Made from refined flour, it is a low-fiber option that is easy on the stomach.
  • Cooked Cereals: Oatmeal, Cream of Wheat, and other hot cereals are gentle and soothing.
  • Eggs: Scrambled or boiled eggs offer a good source of lean protein.
  • Lean Protein: Skinless chicken breast or fish, baked or boiled, is an excellent addition as your stomach tolerates it.

Foods and Habits to Avoid

Just as important as knowing what to eat is knowing what to avoid. Certain foods can exacerbate inflammation and irritate both the stomach and the bowels, prolonging recovery.

  • Spicy and Acidic Foods: Hot peppers, chili, citrus fruits, and tomatoes can increase stomach acidity and irritate the gastric lining.
  • Fatty and Fried Foods: High-fat items, including fried chicken, heavy cream, and rich sauces, slow down digestion and can trigger symptoms.
  • High-Fiber Foods (initially): While fiber is generally healthy, insoluble fiber in whole grains, raw vegetables, and nuts can be too harsh during an acute flare-up. Focus on easily digestible sources of soluble fiber instead.
  • Caffeine and Alcohol: These are both irritants and can stimulate acid production. Caffeinated drinks and alcohol should be avoided entirely.
  • Dairy Products: Many people experience temporary lactose intolerance when sick. It's often best to limit or avoid dairy, aside from some low-fat yogurts with probiotics, until symptoms improve.
  • Sugary Foods and Artificial Sweeteners: Excess sugar can worsen diarrhea. Avoid candies, pastries, and diet products with sugar alcohols like sorbitol.

The Role of Probiotics and Gut Health

Probiotics are beneficial microorganisms that can help restore a healthy balance of bacteria in your gut, which is often disrupted during a gastrointestinal illness.

  • Yogurt and Kefir: Look for products with live and active cultures. These can reintroduce good bacteria to aid digestion and immune function.
  • Gentle Sources: Tempeh and miso are other probiotic-rich foods that may be tolerated.
  • Prebiotics: Once you are feeling better, prebiotic fibers (found in bananas, oats, and cooked onions) can be gradually added to feed the good bacteria in your gut.

Gradually Returning to a Normal Diet

Once you have tolerated bland foods for a couple of days, you can slowly begin reintroducing a wider variety. Start with soft, cooked vegetables and lean proteins, and avoid rushing back to your regular diet, which could trigger a symptom relapse. Maintain smaller, more frequent meals to prevent overloading your digestive system.

Comparison of Food Choices for Gastric and Diarrhea Relief

Conclusion

Managing gastritis and diarrhea requires a mindful and gradual approach to eating. By focusing on hydration with electrolytes and starting with a bland diet like the BRAT protocol, you give your digestive system the rest it needs to recover. Avoiding known irritants such as spicy, fatty, and acidic foods is crucial for preventing further discomfort. As your symptoms subside, you can slowly broaden your diet to include soluble fiber and probiotics to support long-term gut health. Always listen to your body and consult a healthcare professional if symptoms persist or worsen to ensure no underlying issues are missed. For example, for personalized dietary recommendations, you can consult with a gut-health dietitian.

Frequently Asked Questions

The best liquids for rehydration are water and oral rehydration solutions (ORS), which contain the correct balance of electrolytes lost during diarrhea. Clear broths, diluted apple juice, and coconut water can also be beneficial.

The BRAT diet is generally recommended for the first 24 to 48 hours after symptoms of vomiting and severe diarrhea have subsided. After this period, you should gradually reintroduce other foods to ensure you get a more balanced range of nutrients.

Low-fat yogurt with live and active cultures can be helpful because it contains probiotics that help restore gut health. However, some people may have temporary lactose intolerance, so it's best to introduce it slowly and monitor your reaction.

Initially, it is best to avoid high-insoluble fiber foods like whole grains and raw vegetables, which can be harsh on a sensitive digestive system. Focus on soluble fiber from sources like bananas and applesauce, and gradually reintroduce more fiber as you recover.

Acidic fruit juices, like citrus and tomato, should be avoided as they can irritate the stomach. However, diluted, low-sugar apple juice or grape juice may be tolerated for hydration purposes.

Focus on lean, easily digestible protein sources. Good options include baked or boiled skinless chicken breast, fish, and eggs.

Yes, high levels of stress can trigger increased stomach acid production and worsen symptoms of gastritis. Managing stress is an important part of recovery.
