Autoimmune diseases impact about 23.5 million Americans every year. Of those people, about 80% of them are women. That being said, the type of autoimmune disease varies as does the severity of it and its effect on your skin.
Here to talk to us today about autoimmune diseases impacting your skin, and also what you can do about it, is Melissa A. Vance, MSN, FNP-BC, DCNP from our newly expanded Ashtabula office.
What is an autoimmune disease?
“An autoimmune condition is when the body’s own immune system has problems differentiating between itself and foreign invaders. This causes the immune system to attack the body’s own healthy tissues.”
You can think of it like your body’s own cells get confused about which are good ones and which are not. Without being able to differentiate this vitally important function, your immune cells attack the otherwise healthy cells simply because they’re mistaking them for harmful ones.
Why would an autoimmune disease affect the skin?
Autoimmune disorders affect more than just the skin. However, your skin is the outermost layer of your body, and your largest organ.
“Skin is the largest organ in the body and our immune system protects all aspects of our body. Any dysregulation in the immune system can affect any organ or system in our body.”
Because your skin is the first line of defense to the outside world, it’s the first line of immunity defense as well. Your cells here are likely to be attacked as a result.
What are some common autoimmune diseases that show up on the skin?
Not all autoimmune diseases impact the skin. However, we do treat plenty of these conditions that do show up on the skin—and are sometimes even mistaken for other types of skin conditions, and therefore treated ineffectively.
Here are the common autoimmune diseases that show up on your skin:
Alopecia areata – This autoimmune disease is when you experience sudden hair loss and baldness, specifically in patchy areas. This happens when your immune system actually attacks the hair follicles.
Vitiligo – You may have seen this present as areas where the skin loses its pigmented cells called melanocytes. Usually, this happens in patchy areas on the whole body and isn’t just limited to skin; hair and mucous membranes can also experience discoloration.
Morphea – This is a more rare condition that presents in discolored skin patches that are painless. You may find these color changes on the back, chest, or belly, and also your face, legs, and arms. If left untreated, these patches can end up becoming firm, smooth, and dry.
Psoriasis – You’ve likely heard of this autoimmune disease. Psoriasis is fairly common one and shows up as patches of thick red skin that can even look and feel scaly. These patches are often found on the scalp, elbows, knees, lower back, face, palms, and even the soles of your feet.
Lichen sclerosus – While uncommon, this skin condition is when your skin takes on a white, thin appearance. Typically, it affects the genital and anal areas.
Cicatricial alopecia – Different from alopecia areata, this autoimmune disease is an inflammatory condition. It damages your hair follicles, leaving scarring and permanent hair loss behind.
Discoid lupus – This chronic condition shows up as coin-shaped rashes on the skin that get worse when in sunlight. You’ll likely find this autoimmune disease showing up on the scalp, face, and ears more than other areas.
