Types: Piles can be internal or external. Internal piles occur inside the rectum and are usually not visible, while external piles develop outside the anus and can be seen or felt.
Causes: Piles can be caused by increased pressure in the rectal veins. Common causes include chronic constipation, straining during bowel movements, prolonged sitting or standing, obesity, pregnancy, and a low-fiber diet.
Symptoms: Common symptoms of piles include rectal bleeding (bright red blood on the stool or toilet paper), itching, pain or discomfort, swelling around the anus, and a lump near the anus.
