The cause of hemorrhoids is not well defined and may be related to a number of factors. Two commonly cited causes are subluxation of the anal cushion and varicose veins. 1. Submigration of the anal cushion. The anal cushion is a rich network of veins in the anal canal. When the elasticity of the anal cushion is weakened, congestion, hyperplasia and hypertrophy will occur, changing the original structure and detaching from the original position, and the so-called hemorrhoids will be formed. 2. Varicose veins. Due to the rich network of veins within the anal cushion, there is no venous valve within the veins, which is easily congested and stagnant. If there are long-term standing, constipation, pregnancy, prostate hypertrophy and other triggers, it is more likely to lead to varicose veins, enlargement, and so on the appearance of hemorrhoids. Hemorrhoids, to improve the bad lifestyle, such as eating less spicy and irritating food, form a good bowel habit, to prevent constipation, diarrhea, proper exercise, and so on. If the perianal area has obvious discomfort symptoms, you should consult a doctor in time to give reasonable treatment.
