Hypothyroidism happens when your thyroid gland, located at the front of your neck, doesn’t produce enough thyroid hormone (underactive thyroid). There are several types of hypothyroidism. The most common is Hashimoto’s thyroiditis, an autoimmune disease. It is most common in women over age 60. Because the thyroid gland helps regulate your metabolism, low thyroid levels cause your body to slow down and fatigue is one of the predominant symptoms. Symptoms can appear over time and can be hard to diagnose. Left untreated, hypothyroidism can cause serious metabolic dysfunction.

Causes:

In the case of Hashimoto’s thyroiditis, the body is attacking the thyroid glad causing dysfunction. Secondary hypothyroidism is caused by a malfunctioning hypothalamus.

Signs and symptoms;

Fatigue, dry hair and skin, cold intolerance, weight gain, facial puffiness, voice is hoarse, speech is low and forgetfulness
