What is the harmful effect of hyperacidity ?

Explanation

### Step-by-Step Solution:

1. **Understanding Hyperacidity**: Hyperacidity refers to an excessive production of hydrochloric acid (H+) in the stomach. This condition can lead to a decrease in the pH level of the stomach, making it more acidic than normal.

2. **Effects on Stomach Lining**: The increased concentration of H+ ions can disturb the normal pH balance, which is essential for the proper functioning of the stomach. This disturbance can lead to damage to the stomach lining.

3. **Formation of Ulcers**: The damage to the stomach lining can result in the formation of ulcers. These are painful sores that can cause significant discomfort, including swelling and redness in the stomach area.
