What will happen if Mucus is not Secreted by the Gastric Glands

Gastric glands in stomach release Hydrochloric acid enzyme pepsin and mucus
The mucus protects the inner lining of the stomach from the action of hydrochloric acidand enzyme pepsin.
If mucus is not released, it will lead to erosion of the inner lining of the stomach, which can cause acidity and ulcer.
Mucus provides protection against acids and enzymes in stomach.
