IBS (Irritable Bowel Syndrome) is a disorder of gut–brain interaction in which the digestive system can become more sensitive to certain foods, bowel changes and other factors. Common symptoms include abdominal pain or discomfort, bloating, excessive gas, constipation, and loose stools or diarrhea. IBS does not mean that your gut is being damaged by every food you eat.
1. Onion and Garlic
Onion and garlic contain fermentable carbohydrates called fructans, which can trigger bloating, gas or abdominal discomfort in some people with IBS.
2. Certain Fruits
Some fruits contain higher amounts of fermentable carbohydrates and may cause symptoms in sensitive individuals — apple, pear, mango, watermelon and certain dried fruits. This doesn't mean these fruits need to be permanently avoided; individual tolerance matters.
3. Certain Pulses and Legumes
Rajma, chole, whole chickpeas and some other legumes can increase gas and bloating in some people. Instead of eliminating all pulses, try smaller portions and individually assess tolerance.
4. Milk and Some Dairy Products
People who are lactose intolerant may experience bloating, gas, abdominal discomfort or loose stools after consuming milk or other lactose-containing foods. Lactose-free dairy products may be better tolerated, depending on the individual.
5. Artificial Sweeteners
Some sweeteners, particularly sorbitol, mannitol and xylitol, can cause gas, bloating or diarrhea in sensitive individuals. These may be found in some sugar-free chewing gums, candies and other “sugar-free” products.
6. Fried and High-Fat Foods
Large amounts of fried or fatty foods — deep-fried snacks, fast food, oily gravies and high-fat meals — may worsen abdominal discomfort, urgency or diarrhea in some people with IBS.
7. Carbonated Drinks
Soft drinks and other carbonated beverages can increase gas and bloating.
When Should You See a Doctor?
Do not assume every digestive symptom is IBS. Consult a gastroenterologist if symptoms are persistent, severe, new or changing. Seek medical evaluation particularly if you experience:
- Blood in the stool
- Unexplained weight loss
- Persistent vomiting
- Fever
- Severe or worsening abdominal pain
- A significant change in bowel habits
