If you have hyperacidity, you usually feel a burning sensation within your breastbone area (heartburn), as well as a bitter taste in your mouth.
This sensation usually worsens when you bend over or whenever you are lying down. People who consume too much coffee, alcohol and carbonated beverages on a daily basis are at greater risk of developing hyperacidity. Eating spicy and oily foods can also harm your stomach lining and result in gastritis.
