Acidity refers to a set of symptoms caused by an imbalance between the acid secreting mechanism of the stomach and proximal intestine and the protective mechanisms that ensure their safety. The stomach normally secretes acid that is essential in the digestive process. This acid helps in breaking down the food during digestion. When there is excess production of acid by the gastric glands of the stomach, it results in the condition known as acidity. Acidity is responsible for symptoms like dyspepsia, heartburn and the formation of ulcers (erosion of the lining of the stomach or intestines).
Prevention mainly consists of avoiding the known causative factors like
Drugs like NSAID's, steroids etc.
Don’t lie down after meals
Avoiding non-vegetarian diets is also useful in minimizing symptoms of acidity.
