In Ayurveda, increased stomach acid is referred to as "Amlapitta." It is believed to occur due to an aggravated Pitta dosha, which represents the fire element in the body. Pitta dosha governs digestion and metabolism. When Pitta becomes imbalanced, it can lead to excessive acid production. Common causes of Amlapitta include consuming spicy, greasy, or acidic foods, excessive anger or stress, and irregular eating habits.
