Hypothyroidism Symptoms: Causes, Signs & What to Expect

Hypothyroidism, also called underactive thyroid, is a condition in which your thyroid gland doesn't make enough thyroid hormone. This can lead to a number of symptoms, including:

* Fatigue

* Weight gain

* Constipation

* Dry skin

* Brittle hair

* Muscle weakness

* Increased sensitivity to cold

* Menstrual irregularities

* Depression

* Anxiety

* Memory loss

* Joint pain

* Muscle cramps

* Goiter (enlarged thyroid gland)

In severe cases, hypothyroidism can lead to myxedema coma, a life-threatening condition that requires immediate medical treatment.

Hypothyroidism is most common in women, especially those over the age of 50. It can also occur in men and children. The exact cause of hypothyroidism is unknown, but it is thought to be related to several factors, including autoimmune disorders, iodine deficiency, and radiation therapy.

Treatment for hypothyroidism typically involves taking thyroid hormone replacement medication. This medication can help to relieve symptoms and prevent complications.
