What causes hemorrhoids?
Studies have shown that the formation of hemorrhoids is the result of the long-term effects of many factors.
From the perspective of anatomy, because the human body walks upright, the anus is located at the lowest end of the body cavity, gravity factors and the resistance of blood return can easily cause the tortuous expansion of blood vessels to form hemorrhoids.
The anus is the "outlet" for human excretion, and feces are discharged from it every day. If you have long-term constipation, diarrhea or bad habit of squatting on the toilet for a long time, you will inevitably squeeze and rub the anus excessively, causing abnormal expansion of the hemorrhoidal venous plexus and hypertrophy and lowering of the anal pad, leading to bleeding and prolapse of hemorrhoids.
In addition, improper diet, old age and body failure, and other chronic diseases may be the cause of hemorrhoids.
