The presence of hypothyroidism in the body is usually caused by a lack or deficiency of thyroid secretion. It leads to a series of symptoms of metabolic disorders, symptoms of reduced secretion of sex hormones and edema. The organism’s metabolism of nutrients is impaired, and hypothyroidism can lead to anemia that causes pale skin and conjunctiva, as well as fatigue, coldness, drowsiness, thinning hair, and hair loss due to insufficient energy supply. The human physiology requires adequate energy metabolism, and these metabolic deficiencies can also cause symptoms such as constipation due to slowed bowel movements. Decreased production of sex hormones can occur in both male and female patients. In men, decreased hormone production can cause sexual dysfunction and erectile dysfunction, while in women, decreased production of sex hormones can lead to irregular menstrual periods and low menstrual flow. Edema is one of the more common symptoms of hypothyroidism. It occurs mostly in the lower extremity area, where a visible thickening of the legs can be seen and indentations cannot be pressed out with the hand. This edema symptom, which is unique to patients with hypothyroidism, is called mucinous edema. This is mainly caused by the accumulation of metabolites due to the massive breakdown of collagen between tissues. These symptoms occur mainly due to problems with thyroid hormone production and can be effectively relieved by aggressive thyroid supplementation.
