Piles, also known as hemorrhoids, are swollen veins and muscles in the anal canal or around the anus. They often cause bleeding, pain, itching, and protrusion of tissue from the anus. Piles are common during pregnancy or due to straining on the toilet, obesity, lack of fiber, or other factors. Homeopathic medicines can effectively treat piles and their symptoms by addressing the underlying causes without surgery. Maintaining a healthy lifestyle and diet can also help prevent piles.
