In terms of
hypopituitarism (which can be caused by head injuries or
brain / CNS infection), a while ago I was looking at the possibility of adult human growth hormone (HGH) deficiency:
The symptoms of
adult human growth hormone deficiency are:
Adult Human Growth Hormone Deficiency Symptoms
Psychological and Cognitive Symptoms
Anxiety, apprehension, nervousness.
Shyness, withdrawal from others, feelings of social isolation.
Sadness, hopelessness, depression.
Labile emotions (ie, emotions change rapidly and unpredictably, and can be exaggerated).
Poor memory and impaired concentration.
It is unknown whether this impairment in psychological well being is associated specifically with GH deficiency or is due to another factor associated with hypopituitarism.
Sexual
Decrease in sexual function and interest (low libido). This is associated with hair loss and baldness in men.
Energy Levels
Fatigue, tiredness, and reduced vitality.
Decreased energy due to decreased metabolic rate.
Lower tolerance to exercise (due to decreased cardiac output), decrease in strength and stamina.
Metabolic
High levels of LDL (the "bad") cholesterol.
Changes in blood cholesterol concentrations (increase in LDL and decrease in HDL).
Low blood sugar (dizziness or fainting weakness or tiredness, headaches).
Insulin resistance.
Elevated triglyceride levels.
Increased sensitivity to cold or heat.
Heart and Circulation
Increased arterial plaque and blood pressure.
Increased vascular wall thickness.
Weakened heart muscle contraction and heart rate.
Heart problems.
Cool peripheries (cold hand and feet).
Poor venous access.
Muscles
Decreased muscle mass (muscle size) and strength.
Reduced exercise performance.
Body Weight and Body Fat
Decreased lean body mass.
Increase in weight and fat deposition all over the body, particularly, about the waist and trunk.
Bones
Decrease in bone density, making the bones brittle and weak.
Increase in rate of fracture in middle age and beyond.
Skin
The skin becomes dry, thinner, looses its elasticity, and fine lines and wrinkles make an appearance.
Hair
Baldness (in men).
Sleep
Sleep problems.
