Ketones include acetone. The body produces ketones as a consequence of fat digestion. Ketones are specifically created when the body turns to lipids for energy instead of carbohydrates. Although the body can tolerate modest amounts of ketones without harm dangerously excessive levels can be dangerous. Ketosis is a state that develops when the bodys levels of ketones exceed what is normal. Acetone is the most prevalent ketone in the blood. Ketoacidosis which is known to cause comas and is typically fatal can result from ketosis. Diabetes patients frequently experience ketosis. Abdominal pain nausea flu-like symptoms increased thirst and breathing problems are typical symptoms.
