Kidney failure

Acute kidney failure (renal failure) or acute kidney injury is when your kidneys suddenly stop working properly. This means that they are unable to remove salt, water and waste products from the bloodstream.

Growth hormone deficiency

Growth hormone is produced by the pituitary gland located deep inside the brain. Instructions for producing growth hormone come from other parts of the body, for instance, the hypothalamus. If there is a problem with the hypothalamus, the pituitary or the connection between the two, the release of growth hormone will be affected, leading to growth hormone deficiency.
