Anal papilloma is a very common disease in anus and intestines, and its causes are mostly considered to be inflammatory stimulation, local injury and so on. 1. Inflammatory stimulation: If there is chronic inflammation in anal area, such as hemorrhoids, sinusitis, anal canal inflammation, etc., it will stimulate anal papilla repeatedly, which will lead to hypertrophy and hyperplasia of anal papilla and form anal papilloma. 2. Local injury: if the patient has anal fissure or anal stenosis, during defecation, it is easy to make the local tissues of the anus damaged, and secondary bacterial infection occurs, which makes the lymphatic system of the anal papilla impeded, and the anal papilla swollen and enlarged to form anal papilloma. In addition, constipation, dietary inattention, irregular work and rest time, etc. can stimulate the anal papilla, leading to and aggravating the enlargement of anal papilloma. It is recommended that patients develop good daily habits, eat less spicy and stimulating food, prevent constipation and diarrhea, do more exercise to enhance physical fitness, etc. If anal papilloma is detected, it is necessary to consult a doctor in time, listen to the professional doctor’s opinion and give reasonable treatment plan to avoid delaying the condition.
