Hemorrhoids is a disease that affects the veins of the rectum. When blood circulation in the true pelvis is disturbed, a significant increase in intra-abdominal pressure, the nutrition of the organs that are located here (including the rectum) suffers. There is stagnation in the vessels, their expansion and the formation of hemorrhoids. At first, hemorrhoids may not show themselves in any way. However, the boluses are constantly injured during the passage of feces, an increase in pressure in the true pelvis. If the correct diagnosis is not made in time and the treatment is not started, complications and pathologies develop. The most formidable complications are bleeding from hemorrhoids, their thrombosis and necrosis. Depending on the course of the disease, acute and chronic hemorrhoids exist. The acute one develops over several days and is characterized by a stormy cause. In the chronic form, the occurrences of the disease are minimal, which carries a latent danger. Patients do not go to the doctor for a long time, they ignore the problem, which often leads to the development of complications.
