Understanding adult growth hormone deficiency
Will, born with GHD
What is adult GHD?
People who are diagnosed with growth hormone deficiency (GHD) do not produce enough growth hormone. In adults, this can affect their bones, muscles, and body fat.

What causes adult GHD?
Adults with GHD may have been diagnosed in childhood. Some may have been born with GHD, while others developed it during childhood. Most often, the cause is unknown.
Some adults develop GHD as a result of damage to the brain. The hypothalamus and pituitary gland are parts of the brain that are tied to growth hormone. If they are damaged by a head injury, blood clot near the brain, brain surgery, or other factors, it can affect the body’s production of growth hormone.
Being diagnosed with GHD as an adult is rare, with only 6,000 new cases in the United States each year.

What are the signs of adult GHD?
In adults, the signs of GHD may not include height. This is different from children with GHD, for whom short stature is a common symptom. Adults have already reached their full height, so GHD tends to show up in other ways.
These may include:
- Increased fat around the waist
- Decreased muscle mass
- Thinning bones
- Higher cholesterol, particularly LDL (low-density lipoprotein, or the “bad” cholesterol)
How is adult GHD diagnosed?
If your doctor thinks you might have GHD, you may be referred you to an endocrinologist. This is a doctor who specializes in hormone-related disorders. The endocrinologist may order a stimulation or stim test, which measures the level of growth hormone in the body. To get an accurate diagnosis, you might do more than one stim test.
What’s the stim test?
A stim test measures the body’s ability to release the appropriate amount of growth hormone. The test involves artificially stimulating your pituitary gland. Then you have a series of blood tests, to see how much growth hormone your pituitary gland produces over a period of time.
After the diagnosis
Adults diagnosed with GHD may be prescribed growth hormone therapy. This involves taking regular doses of growth hormone. You may have regular follow-up visits to make sure that treatment is working well.
