Q&A

Episode 1164 focuses on The Skin and explains that the skin is not just a protective covering but an important endocrine organ with multiple hormonal functions.

Because the skin produces hormones, converts hormones, responds to hormones, and has its own endocrine feedback systems similar to other endocrine glands.

Vitamin D, which is actually a hormone (often misnamed as a vitamin), is the most well-known hormone produced by the skin.

Ultraviolet B (UVB) rays from sunlight act on 7-dehydrocholesterol in the skin to form previtamin D, which then converts into Vitamin D.

Due to inadequate sun exposure, incorrect timing of sunlight, pollution reducing UVB penetration, and limited exposed skin surface area.

The skin also produces melatonin, serotonin, and small amounts of sex hormones.

Yes, the skin can convert inactive thyroid hormone T4 into its active form T3.

The skin has duplicate versions of the hypothalamic-pituitary-adrenal (HPA) axis and the hypothalamic-pituitary-thyroid (HPT) axis.

Stress activates the skins own endocrine stress response, leading to inflammation, itching, changes in sebum production, and worsening of skin diseases.

Because many endocrine disorders such as diabetes, insulin resistance, thyroid disorders, Cushings syndrome, acromegaly, and autoimmune diseases show visible signs on the skin.
