What sign is characteristic of Hypothyroidism?

In hypothyroidism, the body does not produce enough thyroid hormones, which play a crucial role in regulating metabolism and energy levels. One of the common signs associated with this condition is brittle hair and nails. The deficiency in thyroid hormones leads to a decreased rate of metabolic processes, which can result in hair becoming coarse, dry, and lifeless, leading to increased breakage and brittleness of both hair and nails.

While difficulty concentrating is also a symptom linked to hypothyroidism, it is less distinctive compared to the physical manifestation of brittle hair and nails. High fever is not associated with hypothyroidism; rather, it can indicate an infection or inflammatory response. Frequent infections are generally not considered a hallmark of hypothyroidism either, as the immune function can be affected in various ways but is not directly tied to the characteristic symptoms of this condition.
