What Should I Eat If I Have Gastritis And SIBO?

According to a study published in the World Journal of Gastroenterology, using probiotics alongside standard therapy may increase H. pylori eradication rates and reduce adverse effects, highlighting the nuanced role of diet and gut flora in treating stomach ailments like gastritis. Managing both gastritis and SIBO simultaneously requires a carefully tailored dietary approach that addresses inflammation and bacterial overgrowth.

Quick Summary

A combined gastritis and SIBO diet is a low-acid, low-inflammatory, and low-FODMAP protocol. The focus is on easily digestible proteins, non-irritating vegetables, and bland grains while eliminating common trigger foods and highly fermentable carbohydrates.

Key Points

• Combined Diet Strategy: Address both stomach inflammation (gastritis) and bacterial overgrowth (SIBO) by adopting a low-acid, anti-inflammatory, and low-FODMAP diet.

• Food Choices: Prioritize easily digestible lean proteins, non-acidic fruits (bananas, berries), and low-FODMAP vegetables (carrots, spinach).

• Avoid Triggers: Eliminate acidic foods (tomatoes, citrus), spicy items, high-fat meals, and all high-FODMAP carbohydrates like onions, garlic, and beans.

• Cautious Probiotics: The use of probiotics is controversial for SIBO; consult a healthcare professional before taking them, as they can sometimes worsen symptoms.

• Lifestyle Habits: Implement small, frequent meals, chew food thoroughly, manage stress, and avoid lying down immediately after eating to support digestion and reduce symptoms.

Navigating a Dual Diagnosis: Gastritis and SIBO

Dealing with both gastritis and Small Intestinal Bacterial Overgrowth (SIBO) presents a unique dietary challenge. Gastritis requires a focus on reducing stomach acid and inflammation, while SIBO necessitates limiting fermentable carbohydrates (FODMAPs) that feed bacteria in the small intestine. The goal is to find the right combination of foods that calms the stomach lining without fueling bacterial overgrowth, a task that often requires a highly individualized approach and careful monitoring.

Combining Low-Acid and Low-FODMAP Principles

To effectively manage both conditions, a diet must incorporate the best of both worlds. The following food choices prioritize low-acid, anti-inflammatory properties while remaining low in fermentable carbohydrates. It is recommended to work with a healthcare professional, like a gastroenterologist or registered dietitian, to personalize this plan.

Recommended Food Choices

• Lean Proteins: Opt for skinless poultry (chicken, turkey), fish (grilled, broiled, or steamed), and eggs. These are generally well-tolerated and provide essential nutrients without excess fat that can irritate the stomach.
• Non-Acidic Fruits: Stick to low-acid fruits such as bananas, melons, grapes, strawberries, and blueberries. These fruits are less likely to increase stomach acidity and are generally low in FODMAPs.
• Low-FODMAP Vegetables: Choose non-starchy options like carrots, cucumber, spinach, and bell peppers. Cooking vegetables often makes them easier to digest. Avoid known high-FODMAP vegetables like onions and garlic during the initial elimination phase.
• Safe Grains: Simple, well-cooked grains such as white rice, quinoa, and oatmeal can be a good source of energy. While some whole grains are generally recommended for gastritis, specific SIBO protocols may require gluten-free grains to avoid irritation.
• Healthy Fats: Healthy fats from sources like olive oil and avocados are important but should be consumed in moderation. Excessive fats can slow down digestion and exacerbate gastritis symptoms.
• Herbal Teas: Chamomile, ginger, and peppermint teas are known for their anti-inflammatory and soothing properties for the stomach. Peppermint oil in particular has shown promise in managing SIBO symptoms.

Foods and Substances to Avoid

Just as important as knowing what to eat is understanding what to eliminate. These items can trigger inflammation and feed bacterial overgrowth, leading to symptom flare-ups.

Foods and Drinks to Eliminate

• Acidic Foods: Stay away from acidic foods like tomatoes and citrus fruits, which can aggravate gastritis.
• Spicy and Fatty Foods: Spicy condiments and high-fat foods, including fried items, red meats, and rich desserts, should be avoided as they can irritate the stomach lining.
• High-FODMAP Carbohydrates: Avoid high-FODMAP foods like garlic, onions, beans, lentils, wheat, rye, and many artificial sweeteners, which are fermented by gut bacteria and worsen SIBO symptoms.
• Alcohol and Caffeine: Both alcohol and caffeinated drinks can irritate the stomach and interfere with healing.
• Refined Sugars: Processed foods and sugary snacks can promote inflammation and should be limited.

The Role of Probiotics and Supplementation

For those with both conditions, the role of probiotics is complex. While probiotics can help rebuild gut flora damaged by inflammation and potential antibiotic use, certain strains can worsen SIBO symptoms, particularly in methane-dominant cases.

• Saccharomyces boulardii: This yeast-based probiotic has shown some promise, especially when combined with antibiotics, and is often better tolerated by SIBO patients.
• Herbal Antimicrobials: Some practitioners recommend herbal antimicrobial therapy to help reduce bacterial overgrowth in the small intestine, but this should be done under expert supervision.
• Digestive Enzymes: Supplementing with digestive enzymes can help break down food, improving nutrient absorption and reducing fermentation.

Consulting with a healthcare provider before introducing any supplements is vital to ensure they align with your specific needs and treatment plan.

Lifestyle and Eating Habits

Beyond food choices, how you eat plays a crucial role in managing both conditions.

• Small, Frequent Meals: Eating smaller, more frequent meals throughout the day, rather than three large ones, can prevent stomach irritation and avoid overloading the digestive system.
• Thorough Chewing: Chewing your food thoroughly aids digestion and reduces the burden on your stomach and small intestine.
• Stress Management: Chronic stress can negatively impact gut motility and increase stomach acid. Incorporate relaxation techniques like meditation or yoga to reduce stress.
• Hydration: Drink plenty of water throughout the day to support overall digestive health and keep stomach acid diluted.
• Avoid Lying Down After Eating: Wait at least a few hours after eating before lying down to prevent acid reflux.

Conclusion

Effectively managing a combined gastritis and SIBO diagnosis requires a disciplined dietary approach that is both anti-inflammatory and low in fermentable carbohydrates. While the diet can seem restrictive, focusing on nutrient-dense, gentle foods and avoiding common triggers can significantly reduce symptoms and promote healing. A partnership with a qualified healthcare professional is crucial for tailoring this approach, especially concerning probiotics and supplements, ensuring you get the best possible outcome for your digestive health. Following these guidelines can help you take control of your symptoms and pave the way toward a more comfortable and balanced life.
