From the Guidelines
For IBS with bloating and hyperacidity, a low-FODMAP diet is the most effective dietary approach, as it eliminates fermentable carbohydrates that can trigger symptoms. This recommendation is based on the latest guidelines from the British Society of Gastroenterology 1, which suggest that a low-FODMAP diet can reduce the risk of remaining symptomatic in IBS patients. Good food choices on a low-FODMAP diet include:
- Lean proteins like chicken and fish
- Easily digestible grains such as rice and oats
- Cooked vegetables like carrots and spinach
- Low-acid fruits like bananas and melons It is also important to avoid common triggers, including:
- Spicy foods
- Caffeine
- Alcohol
- Fatty foods
- Citrus fruits
- Tomatoes
- Onions
- Garlic
- Carbonated beverages In addition to a low-FODMAP diet, incorporating soluble fiber sources gradually, such as oats and flaxseeds, can help regulate bowel movements without increasing gas 1. Probiotic-rich foods like yogurt with live cultures may also help balance gut bacteria. It is essential to keep a food diary to identify personal triggers, as IBS varies between individuals. Eating smaller, more frequent meals, staying well-hydrated with water, and chewing food thoroughly and eating slowly can also help reduce symptoms. These dietary changes work by reducing fermentation in the gut, decreasing acid production, and minimizing irritation to the digestive tract lining.
From the Research
Dietary Management for IBS with Bloating and Hyperacidity
The management of Irritable Bowel Syndrome (IBS) with bloating and hyperacidity can be approached through dietary changes. Key considerations include:
- A low FODMAP diet, which restricts fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, has been shown to reduce symptoms in patients with IBS 2, 3, 4.
- Probiotics, particularly Lactobacillus and Bifidobacterium, may also be effective in relieving IBS symptoms 2, 3.
- A multistrain probiotic formulation may help restore Bifidobacterium species in patients on a low FODMAP diet 3.
Foods to Consider
Foods that are low in FODMAPs and may be beneficial for IBS patients include:
- Gluten-free bread and pasta
- Lactose-free or low-lactose dairy products
- Fresh fruits and vegetables, except for those high in FODMAPs (e.g., onions, garlic, beans)
- Lean proteins, such as chicken, fish, and eggs
- Healthy fats, such as olive oil and avocado
Challenges and Considerations
Dietary management of IBS can be challenging, and patients may require guidance from a qualified dietitian to ensure nutritional adequacy and compliance 5, 4, 6. Additionally, restrictive diets may have potential risks, such as eating disorder risk, and should be approached with caution 5. Physician-dietitian collaboration is essential for successful outcomes in IBS patients 6.
