In medical terms, an anal tag is known as a sentinel pile, which is simply a common external hemorrhoid. It results from prolonged non-healing anal fissures and repeated local inflammatory irritation, leading to tissue hyperplasia. The only way to remove the anal tag is through surgical removal, as medications alone cannot cure it. It is advisable to maintain a light diet, drink plenty of water, and consume lots of vegetables and fruits to keep bowel movements regular and soft, which can help reduce the occurrence of anal fissures. During flare-ups, one should avoid consuming beef, lamb, seafood, and other potentially irritating foods, and avoid prolonged sitting or standing. If stools are dry, products such as hemp seed pills, lactulose oral solution, and polyethylene glycol 4000 can be used to effectively soften the stools and alleviate symptoms of anal fissures. (Please use medications under the guidance of a doctor.)
