Ghrelin agonistic treatments can be used to treat illnesses such as anorexia and loss of appetites in cancer patients.

Amylin controls glucose homeostasis and gastric motility Glucose-dependent insulinotropic polypeptide possesses an acute influence on food intake through its effects on adipocytes Oxyntomodulin
Growth hormone therapy use. Other articles describe GH physiology, diseases of GH excess (acromegaly and pituitary gigantism), deficiency, the recent phenomenon of HGH controversies, growth hormone in sports, and growth hormone for cows.

Nearly painless insulin syringes make this less trying than is usually anticipated, but perceived discomfort is
