Piles, also known as hemorrhoids, are swollen veins in the rectum and anus that can cause discomfort, itching, pain, and bleeding. Ayurveda categorizes piles into three types based on the predominant dosha: Vata, Pitta, and Kapha, each presenting with distinct symptoms. The condition is believed to result from chronic constipation, dietary habits, and lifestyle choices that lead to an imbalance of the doshas, particularly Vata dosha, causing digestive issues and leading to the formation of piles.
