Hi Julie..
Ketones are produced by the body when the cells do not have enough glucose energy. The body then breaks down fat to produce energy and the breakdown products are called Ketones. Ketones can be used as fuel by the muscles, heart, kidneys and brain.
If a person has diabetes, ketones are produced when there is a lack of insulin and the BG levels are usually high.
Ketones can be measured in both the blood and the urine. Positive urine ketone readings are found in anyone who is fasting..regardless of whether or not they have diabetes.
It is particularly important to check for ketones if you are ill, under a lot of stress, feeling sick and vomiting, as well as when your BG level is consistently high.
The ketones produced when the body is starving, or when there is a deficiency of insulin, are chemically the same. But often described differently as "Starvation Ketones" or "Diabetes Ketones" since they are produced in different situations.
