HGH deficiency makes sense indeed.
“Growth hormone deficiency has different effects at different ages. In newborn infants the primary manifestations may be hypoglycemia or micropenis, while in later infancy and childhood, growth failure is more likely. Deficiency in adults is rare, but may feature diminished lean body mass, poor bone density, and a number of physical and psychological symptoms. Psychological symptoms include poor memory, social withdrawal, and depression, while physical symptoms may include loss of strength, stamina, and musculature. Other hormonal or glandular disorders frequently coincide with diminished growth hormone production.”
[edit] In adulthood
The incidence of genuine adult-onset GHD, normally due to pituitary tumours, is estimated at 10 per million[4].
Recognised effects include:
Reduced muscle mass and strength
Reduced bone mass and strength
Reduced quality of life, particularly energy levels
Impaired concentration and loss of memory
Increased body fat, particularly around the waistline
Lipid abnormalities, particularly raised LDL cholesterol
Insulin resistance
Increased levels of fibrinogen and plasminogen activator inhibitor
Cardiac dysfunction, including a thickened intima media
I have most of the symptons above…
