Growth Hormone Deficiency (cont.)

When to Seek Medical Care

If there is a question of growth hormone deficiency in either a child or an adult, consultation with a pediatric or adult endocrinologist, as appropriate, is recommended. The endocrinologist may order an insulin hypoglycemia test wihich is the gold standard for determining HGH deficiency.

  • insulin (hormone that regulates blood sugar levels) is given through an IV to produce a low plasma glucose (a sugar) level. The peak growth hormone level is measured 20-30 minutes later.
  • If the peak growth hormone level is less than 10 mcg/mL in children or less than 3 mcg/mL in adults, growth hormone deficiency is diagnosed.

Persons with growth hormone deficiency may have increased total cholesterol, low-density lipoprotein (LDL) cholesterol, apolipoprotein B, and triglyceride levels.

Other tests that may be performed include a CT scan and/or MRI of the brain and/or bones. Images from these tests may reveal tumors. Reduced bone density can be evaluated by a DEXA or bone density scan.
