Hypothyroid is a condition that causes low thyroid function. The thyroid is a gland in the neck that makes thyroid hormone. Thyroid hormone helps regulate the body’s energy, metabolism and other functions.
Doctors can diagnose hypothyroid through a blood test. The blood test checks the following:
Thyroid stimulating hormone (TSH) is a hormone from the brain that tells the thyroid to turn on. If TSH levels are high, it may mean the thyroid is not working properly.
Thyroxine or free thyroxine (T4 or free T4) level is the actual level of thyroid hormone is flowing throughout the body. This tells how much hormone the body is making.
Subclinical hypothyroidism. This condition is common in children with WS. It is a condition in which the TSH levels are a little high but the T4 level is normal.
Feeling cold more easily
Dry, coarse (rough) hair and skin
In most cases, hypothyroid issues are mild in people with WS. They might not need medication to replace the body’s missing thyroid hormone. If your child does need thyroid medication, it comes in a pill. Children with WS also need blood tests every 1-2 years to check their thyroid.
