4. Dry, Itchy Skin vs. Swollen, Moist Skin
Skin changes can be caused by a lot of things, so don’t jump right to thyroid disorder if you experience this symptom. However, having either too much or too little thyroid hormone can definitely affect the texture and quality of your skin.
Much like hair follicles, skin cells typically have a high turnover. When that turnover slows due to hypothyroidism, cells hang around longer before being shed and replaced. That leads to dry and irritable skin. But when the cells are turning over too quickly, you’ll find your skin thickens and appears swollen and moist.
