Stomach issues like bloating, cramps, gas, or acidity can turn everyday life into a challenge. While triggers differ from person to person, certain foods are more likely to irritate your digestive system. Dr. Anukalp Prakash, director of Gastroenterology at CK Birla Hospital, Gurugram, shares 9 foods that may cause stomach discomfort and how to handle them.


1. Spicy Foods – Handle the Heat Carefully

Chili peppers, hot sauces, and heavily spiced dishes can irritate your stomach lining, leading to acidity or heartburn. Individuals with acid reflux or gastritis should be cautious, as the heat can worsen their symptoms.


2. Fried and Greasy Foods – Heavy on Digestion

Deep-fried snacks, oily curries, and fast foods contain high amounts of fat that slow digestion, making you feel bloated and heavy. Over time, these can also trigger acid reflux and indigestion.


3. Dairy Products – Know Your Lactose Limits

Milk, cheese, and ice cream can cause bloating, gas, and diarrhea for people with lactose intolerance. If your body struggles to digest lactose, consuming dairy can quickly turn into a digestive disaster.


4. Carbonated Drinks – Fizz Isn’t Always Fun

Soda, sparkling water, and beer introduce extra gas into your digestive system, often resulting in burping, bloating, or stomach discomfort. Moderation is key if you love your fizzy drinks.


5. Caffeinated Beverages – Acid Alert

Coffee, concentrated tea, and energy drinks stimulate stomach acid secretion. While they can energize your day, they may aggravate heartburn or acidity in sensitive individuals.


6. Packaged and Processed Foods – Convenience Comes at a Cost

Instant noodles, chips, and ready-to-eat meals are packed with salt, preservatives, and unhealthy fats. These ingredients can irritate your gut, lead to water retention, and cause bloating.


7. Sweeteners – Not Always Sweet for Your Stomach

Artificial sugar substitutes like sorbitol, mannitol, and xylitol are poorly absorbed in the small intestine, causing gas, bloating, and sometimes diarrhea. Keep an eye on sugar-free products if you notice digestive issues.


8. beans and Lentils – The Gas Factor

Rich in fiber and nutrients, beans and lentils are healthy but can ferment in the gut, producing gas and discomfort for some people. Proper soaking and cooking can reduce this effect.


9. Citrus fruits – Acid Overload

Oranges, lemons, and grapefruits are acidic and can trigger acid reflux or heartburn in sensitive stomachs. Moderation or pairing citrus with non-acidic foods can help.


Tips to Reduce Stomach Discomfort

Keep a food diary to identify your personal triggers.

Avoid eliminating entire food groups—focus on portion control and preparation methods.

Cooking, soaking, or combining foods differently can make them easier to digest.

Pay attention to how your body responds and adjust your diet accordingly.


By making informed food choices, you can prevent digestive distress while still enjoying a varied, nutritious diet. Listening to your body and moderating certain foods is often enough to keep your stomach happy.
