Maybe you’ve thought that HS is caused by poor hygiene, being overweight, or cigarette smoking. Maybe you’ve even heard it’s an STD. The important thing to remember is that HS is not your fault.
While the exact cause is unknown, medical science has shown that HS is an immune disease. With HS, your body produces too much of a protein called TNF-alpha. This, along with other proteins, leads to increased inflammation. Which in turn leads to abscesses that may appear underneath or on the surface of your skin. So it’s active inside your body, but visible on the outside. HS is a chronic disease, which means it’s a disease that lasts a long time.
