How bad is a TSH level of 15.19?

A TSH level of 15.19 mIU/L is considered high and may indicate an underactive thyroid gland (hypothyroidism). Normal TSH levels typically range from 0.4 to 4 mIU/L. TSH levels above 10 mIU/L are generally considered to be abnormal.

A high TSH level suggests that the thyroid gland is not producing enough thyroid hormones, which can lead to a variety of symptoms including fatigue, weight gain, constipation, dry skin, hair loss, and menstrual irregularities.

If your TSH level is 15.19 mIU/L, it's important to see a doctor for further evaluation and management. Treatment for hypothyroidism typically involves taking thyroid hormone replacement medication to help bring TSH levels back to normal and alleviate symptoms.
