Which suffix indicates the presence of ketones in medical terms?

The suffix that indicates the presence of ketones in medical terminology is "-keton/o." This suffix is derived from the term "ketone," which refers to a type of organic compound characterized by the presence of a carbonyl group (C=O) attached to two carbon atoms. Ketones can be produced during metabolism, particularly when the body is in a state of fasting, low carbohydrate intake, or uncontrolled diabetes, leading to increased levels of ketones in the blood. Recognizing this suffix is essential in various medical contexts, such as understanding conditions like diabetic ketoacidosis, where high levels of ketones can have significant impacts on health.

The other suffixes listed do not relate to ketones. For instance, "-isch/o" pertains to the concept of deficiency or restriction, "-jejun/o" refers to the jejunum, a part of the small intestine, and "-irid/o" relates to the iris of the eye. Thus, their meanings are distinct and do not share the connection to ketones present with "-keton/o." Understanding the specific meanings of these medical suffixes can enhance comprehension during medical assessments and discussions.
