What disease is caused by bacteria and an overproduction of sebum

Acne develops when sebum — an oily substance that lubricates your hair and skin — and dead skin cells plug hair follicles. Bacteria can trigger inflammation and infection resulting in more severe acne.

What causes overproduction of sebum?

The main cause of an overproduction of sebum is hormonal imbalances, including as a result of puberty and pregnancy. “As well as hormones, heat, exercise and genetics play a part,” says Kate Kerr, acclaimed clinical facialist.

What bacteria eats sebum?

Battle of the bacteria On one side of the battle is Propionibacterium acnes, a common skin bacteria. This species lives in our pores and hair follicles, and feeds on the sebum that our sebaceous glands produce.

What is overproduction of sebum called?

Sebaceous glands secrete an oily substance called sebum. This helps protect the skin from the outside environment. Due to an overgrowth of oil-producing cells, sebum can become trapped inside the gland, causing it to swell and form a bump under the skin. This is known as sebaceous hyperplasia.

What disorder is associated with sebaceous glands?

Several medical conditions are related with sebaceous gland pathology, such as acne, sebaceous hyperplasia, sebaceous adenoma and sebaceous carcinoma. Acne is a common, complex, chronic disorder of the human pilosebaceous unit that mostly occurs in adolescence and young adulthood.

What hormone causes oily skin?

Hormones and oily skin seem to go hand in hand. Androgens are the hormones mostly responsible for oil production, and sometimes they can fluctuate, stimulating an increase in sebum production. This often happens during puberty, just before menstruation, during pregnancy and during menopause.

What hormone causes sebum production?

Sebum production is under the control of sex hormones (androgens). The most active androgens are testosterone, 5-testosterone (DHT) and 5-androstene-317diol. These hormones and others are made by the sex glands (ovary in females, testis in males) and by the adrenal gland.
