The harms of pelvic congestion are as follows: 1. If the time of pelvic congestion is relatively short, the harms will be relatively small. This is because during pelvic congestion, blood circulation in the pelvic area is accelerated and the amount of blood will increase. This will lead to metabolic waste from other parts of the body, as well as viruses and bacteria to take this opportunity to spread to the pelvic tissues, which will lead to pelvic infections.2. It may compress the pelvic tissues, and when pelvic congestion occurs pelvic blood vessels dilate, and vascular permeability increases, which may lead to the leakage of nutrients in the blood out of the blood vessels, which can cause pelvic infections.3. It may cause other serious diseases to be transferred to the pelvic blood circulation through the pelvic blood circulation. Pelvic blood circulation and transfer to the pelvis, for example, tumors can be accelerated to the pelvis in this way, that is, with the help of blood circulation.
