It is important to test for ketone especially if you have type 1 diabetes. (Insulin dependent). Ketones gather if you don’t have enough insulin. They can make you feel sick and make you vomit. Always keep a supply of ketostix in case of illnesses, unless you have a meter for testing blood ketones.
Ketones are an acid remaining when the body burns its own fat.
When the body has insufficient insulin, it cannot get glucose from the blood into the body's cells to use as energy and will instead begin to burn fat.
When the body is burning too much fat, it may cause ketones to become present in the bloodstream.
Ketoacidosis is an emergency condition and if not treated can result in coma and death. Ketoacidosis does not develop quickly; blood glucose usually rise over a 24-48 hour period.
