Why Do You Feel Acidity After Eating?

Ever finished a meal and suddenly felt a burning sensation in your chest or throat? You're not alone. Millions of people experience acidity after meals, particularly in India, where cuisine is rich in spices, oils, tea, coffee, and heavy foods.

Symptoms include:

Burning sensation in chest and throat

Bloating and gas

Sour taste at the back of the mouth

Burping or indigestion

Acidity occurs when stomach acid rises into the oesophagus - the tube connecting your mouth and stomach. Essentially, the acid meant to digest your food backfires.

Common Causes of Acidity After Meals

Heavy Meals

Overeating slows digestion and increases stomach pressure, forcing acid upwards. Symptoms: fullness, bloating, gas, sluggishness

Spicy Foods

Chilli, garam masala, and other spice mixes can irritate the stomach lining, especially if eaten at night.

Tea & Coffee

Caffeine relaxes the lower oesophageal sphincter (the "gate" keeping acid in your stomach), triggering reflux - particularly on an empty stomach.

Greasy & Oily Foods

Fried snacks, pooris, bhajiyas, biryani, and heavy gravies slow digestion and cause bloating and acidity.

Eating Too Fast

Poorly chewed food takes longer to digest, increasing acidity.

Sleeping Immediately After Eating

Lying down after meals allows acid to travel upwards - avoid this for at least 2 hours.

Stress

High stress levels impair digestion and can cause acidity during exams or high-pressure workdays.

Carbonated Drinks

Soda and fizzy drinks release gas in the stomach, increasing pressure and reflux.

Food Sensitivities

Lactose intolerance, chocolate, citrus fruits, and tomatoes may trigger post-meal acidity.

Why Gas and Bloating Occur After Eating

Gas forms when undigested food ferments in the stomach or intestines. Common reasons:

Poor digestion

High-fat or spicy meals

Rapid eating

Food intolerances

Excessive tea or coffee

Insufficient water intake

Bloating often combines gas and acidity, signalling your digestive system needs attention.
