Quick GuideThyroid Anatomy, Symptoms, and Disorders
Hypothyroidism results from the thyroid gland producing an insufficient amount of thyroid hormone. It can develop from problems within the thyroid gland, pituitary gland, or hypothalamus. Symptoms of hypothyroidism can include:
- Poor concentration or feeling mentally "foggy"
- Dry skin
- Feeling cold
- Fluid retention
- Muscle and joint aches
- Prolonged or excessive menstrual bleeding in women
Some common causes of hypothyroidism include:
- Hashimoto's thyroiditis (an autoimmune condition that causes inflammation of the thyroid gland)
- Thyroid hormone resistance
- Other types of thyroiditis (inflammation of the thyroid), such as acute thyroiditis and postpartum thyroiditis
Hyperthyroidism describes excessive production of thyroid hormone, a less common condition than hypothyroidism. Symptoms of hypothyroidism usually relate to increased metabolism. In mild cases, there may not be apparent symptoms. Symptoms and signs of hyperthyroidism can include:
- Fast heart rate
- Intolerance for heat
- Increase in bowel movements
- Increased sweating
- Concentration problems
- Unintentional weight loss
Some of the most common causes of hyperthyroidism are:
