Thyroid good, everything is good – how the thyroid affects your skin

Brittle nails, dry skin, hair loss – if you are prone to symptoms like these, it could possibly be due to the function of your thyroid. We'll explain to you why this is and what you can do about it.

The job of our thyroid

The thyroid is a relatively small organ in comparison, but has major effects on the organism. It sits below the larynx and looks somewhat similar to a butterfly. The organ produces the two hormones thyroxine and triiodothyronine, or T4 and T3 for short.

These two substances regulate our body's metabolism, direct the function of the heart and circulation, stomach and intestines, nerves and muscles. They also have an influence on personality, mental well-being as well as the growth of skin, hair and nails.

When the thyroid “no longer ticks properly”

If the thyroid gets out of balance, i.e. if there is over- or under-function, this has a number of effects on our body - including skin, hair and nails. Many people with a thyroid disorder report hair loss, brittle nails, or dry skin. Thin and fine hair is often a typical sign of an overactive thyroid. The hair falls out more quickly, is thinner, finer and sometimes more brittle. The same applies to the fingernails. The skin, in turn, is warmer than usual, tends to become moist, and often itches more quickly or is red. Hair loss also occurs with hypothyroidism. Skin and hair are usually dry, rough, and nails are brittle. It is not uncommon for longitudinal or transverse grooves to appear, or the nail plate to flatten. Since the metabolism tends to “run on the back burner” in hypothyroidism, the body temperature also drops: the skin appears cool and pale, and sometimes looks swollen. The eyelids in particular are prone to swelling. Other effects can include fatigue, freezing, listlessness or weight gain if you maintain the same diet.

What you can do about it

If you suspect that you have an overactive or underactive thyroid, you should definitely have this checked by a doctor. He will go through your symptoms with you and, if necessary, can prescribe you appropriate hormone-lowering or increasing medication or prescribe therapy for you.
