The cause of hemangioma is mainly due to the dysfunction of the blood vessel wall, mainly because the wall becomes thin and the level of blood vessels becomes unclear. Smoking and drinking can cause damage to the blood vessel wall, and it is a long-term chronic process. Therefore, patients with hemangioma are not recommended to continue smoking and drinking, especially smoking, which is very harmful to blood vessels, not only causing arteriosclerosis, but also causing hemangioma. Don’t drink a lot of alcohol or drink a lot of alcohol at once, it will cause hardening or stiffening of the blood vessel wall, and hardening is a cause of hemangioma. So if there is a hemangioma, it is recommended not to continue smoking or drinking.
