# What causes acidity, and how can I prevent it?



## Answers

### Answer by Sofie De Clercq

Acidity or heartburn happens when stomach acid flows back into the food pipe, causing a burning sensation in the chest or throat.

Common triggers include large or late-night meals, spicy and fried food, too much tea or coffee, alcohol, smoking, being overweight, stress, and lying down soon after eating.

Prevention tips: eat smaller meals, avoid eating two to three hours before bed, raise the head of your bed slightly, reduce trigger foods and manage weight. Occasional acidity is common, but frequent heartburn, difficulty swallowing, weight loss or vomiting blood need a doctor’s evaluation.
