Hemorrhoids are usually divided into three types: internal, external and mixed hemorrhoids.
Internal hemorrhoids are varicose vein clusters above the dentate line, mainly caused by poor diet or sedentary reasons, usually manifested as painless blood in stool, prolapse or anal itching and other symptoms.
External hemorrhoids are varicose vein masses below the dentate line, mainly caused by occupational or genetic factors, usually manifested as anal discomfort or swelling, pain and other symptoms.
Mixed hemorrhoids are usually a combination of internal and external hemorrhoids, mainly caused by occupation or improper diet, and usually show symptoms such as blood in the stool, prolapse of anal swelling or anal pain and swelling.
Regardless of the type of hemorrhoids, people are advised to prevent, diagnose and treat them early. Minimize perianal disorders that bring pain to the body and affect health.
