Acidity occurs when the kidneys are unable to remove an excess of acid created by the stomach's gastric glands. It is commonly associated with indigestion, reflux, and heartburn. Acidity is usually caused by eating spicy foods, drinking coffee, eating too much, and following a low-fibre diet. To get rid of acidity, choose Dr. Sharda Ayurveda's Ayurvedic Treatment for Acidity.
