What Could Cause Armpit Fat? 8 Possible Triggers (List)

Hair Follicles

Inflamed or blocked hair follicles can cause armpit fat or armpit bulge. The hair follicle looks like a tiny tube surrounding the hair strand and root. A person is born with more than five million hair follicles all over their body. Moreover, over one million hair follicles cover the head.

The armpits have hair follicles like other parts of the body. In the past, most people pull out the hair from their armpits for cosmetic reasons. However, there are different procedures today that better and safer. 

It is possible to damage the hair follicles from improper plucking of hair, causing them to become inflamed or blocked. The medical term for the condition is hidradenitis suppurativa. The armpit could show local inflammation because the area’s lymph nodes react to skin irritations. They could be trying to filter out excess fluid, bacteria, and other substances. In addition, the lymph nodes could swell because of chemical irritants like an ingrown hair, folliculitis (inflammation of the hair follicles), and minor wounds because of hair removal or deodorant. 

It is vital to keep in mind that hair follicles are essential because they help repair the skin after an injury or wound. Moreover, they produce new blood vessels and new neuron cells for the nervous system.
