Likely. At a listed age of 40, you could have simply had growth hormone levels drop off with age, as they do in everyone, but more than expected. If they were normal during the teen years, which we cannot know, you likely cannot blame this for your height. If the growth centers in your bones are closed, as they do in most by late teens, you cannot grow taller.
Misnomer. "Growth hormone" is a poorly-named hormone that continues to function in adults, though we don't know exactly how. A spot growth hormone assay is worthless but if you have low IGF-1 and/or some other appropriate assay, you might be one of those (rare) folks who will feel incredibly better on replacement of the hormone. This is controversial. I'd get two opinions.
How old are you? What is your bone age? Please provide more information. Thanks.
GH stim test. Hi. To test if you're GH-deficient (GH-D), a screening IGF-1 can be drawn. If it's well in the normal range, GH-D is unlikely. Stringent diagnostic criteria require doing a GH-stimulation test. This is done either by injection insulin IV to cause hypoglycemia (stimulates GH in normals but) or infusing arginine & GH-releasing hormone (stimulates GH in normals). GH-D has diagnostic criteria in tests.
Very rare in adults. In children GH deficiency may be suspected if the child is short and growth is slow. GH deficiency is usually something you are born with and rarely shows up in adults unless they have had surgery or radiation in the area of the pituitary gland. If that is the case you should see an endocrinologist but if not GH deficiency is very very unlikely.
Endocrinologist. Because of the need for stimulation testing to properly diagnose gh deficiency, such a patient will already be seeing an endocrinologist. Children are usually treated for this barring malignancy. For adults treatment is more optional.
Not high. The true prevalence of adult-onset gh deficiency is difficult to estimate with certainty but a reasonable estimate may be obtained from prevalence data for pituitary macroadenoma, which approximates to 1:10000 population. Addition of cases of childhood-onset ghd persisting into adult life gives an overall prevalence of between 2 and 3 per 10000 population.
Doubtful. Gh deficiendy is unusual. Many more common things cause daily tiredness. Lack of sleep (<8hrs) or poor quality sleep are very common, anemia, low thyroid, other metabolic abnormalities, adrenal fatigue, low hormones, and the list goes on. Go to the a4m.

Unlikely but possble. There are many causes of fatigue, growth hormone deficiency is an uncommon one.
I have a growth hormone deficiency, would this mess up a pregnancy test? Would it affect my chances of getting pregnant? I want to learn more on this.
Highly variable. Adult growth hormone deficiency is a highly variable disorder. Different adults will show different effects. Individuals will need to be assessed and testing will need to be done to assess fertility.
Pituitary activity. There are several reasons why children or adults can have a pituitary that is unable to make enough hgh for adequate growth or metabolic wellbeing. Consult a real endocrinologist if you think you or your child may have a deficiency of gh.
Depends on puberty. The closure of the bony growth plates is mainly regulated by pubertal changes in sex hormones (estrogen in girls; testosterone in boys). If you had only gh deficiency but with normal sex hormones, then the growth plates usually fuse around puberty. With pan-hypopituitarism, (gh and gonadal hormone deficiency), the growth plate closure will depend on how quickly and how much sex hormones are given.
Not necessarily. Were you treated? For how long? A simple x-ray can tell your doctor whether you have any other growth potential.
Deficiency of hGH in. Very rare, unless you have had prior pituitary surgery or radiation. Even more rare is aghd due to head trauma. Most quack doctors make the diagnosis to sell hgh. See a real endocrinologist.
Mysterious. Along with "hypophyseal-pituitary axis disorder", this is a poorly-understood. There's no doubt that some older adults feel much better when supplemented with a bit of growth hormone. And it's a popular diagnosis for quacks to sell growth hormone to troubled souls. A specialist knows how to do the lab work but there's no hard-and-fast criteria yet.
Lots of things. Congenital pituitary abnormalities, brain tumors, brain injuries, radiation to the brain, oxygen deprivation, hereditary gh deficiency, etc. In many pediatric cases, it's iatrogenic because the cause is still unknown.
