First of all, hemorrhoids and anal fissure are two kinds of diseases, both belong to the anus and intestines, hemorrhoids recurrent episodes and daily diet structure, living habits and so on, anal fissure recurrent episodes and anal stenosis, constipation and so on have a certain relationship. 1. Recurrent hemorrhoids: (1) dietary structure: if the diet is not regular, often overeating, or often eat some spicy and stimulating food, a lot of alcohol, etc., it is easy to cause constipation, and repeated constipation leads to an increase in intra-abdominal pressure during defecation, which is easy to cause the rectal veins to be tortuous, which can lead to hemorrhoids, or exacerbate the symptoms of hemorrhoids, so that the recurrence of hemorrhoids. (2) lifestyle habits: often stay up late, or lack of exercise, sedentary standing or squatting, etc., easy to cause hemorrhoidal venous reflux is not smooth, thus leading to hemorrhoids recurrence. 2. Anal fissure recurrence: (1) anal stenosis: the sphincter at the anus of the human body has the function of tightening and expanding, when anal fissure is formed, the sphincter will produce a certain amount of stimulation, so that it is in a state of contraction for a long period of time, which will easily cause anal stenosis, and in the future when defecating, no matter what kind of stools are, it is easy to crack the skin at the anus, leading to recurrent episodes of anal fissure. (2) Constipation: Patients with constipation problems, due to hard, dry stools, will use excessive force during defecation, causing damage to the anal sphincter muscle and local mucous membranes, resulting in anal fissure or causing anal fissure to occur repeatedly. It is recommended that patients change their bad dietary habits, and actively go to the hospital when the disease occurs, so as not to delay the condition.
