The key to using gum colour as a way of identifying health problems in your pet is to know the normal gum colour of your pet so you can identify when that colour changes in some way.

Endocrine hormone. A chemical substance that is produced by an endocrine gland and then secreted directly into the blood stream and carried throughout the body where they bind to a target organ cell with specific receptors triggering a reaction. Hyperglycemic Hormone. Promotes a rise in the blood glucose levels.
A hormone is a chemical messenger produced by a cell that effects specific change in the cellular activity of other cells (target cells). Unlike exocrine glands (which produce substances such as saliva, milk, stomach acid and digestive enzymes), endocrine glands do not secrete substances into ducts (tubes).
