Question

Ketonuria is due to
(a)Intake of excess sugar
(b)Diabetes insipidus
(c)Diabetes mellitus
(d)High blood pressure

Answer 1

Hint: Ketonuria is basically a medical condition in which ketone bodies are detected in the urine. It is used as an alternative source of energy due to which the body produces excess ketones.

Complete answer:
Ketonuria is a condition under which high ketone levels are found in urine. It is also called ketoaciduria and acetonuria.
Ketones or ketone bodies are basically types of acids that the body makes when fats and proteins are metabolised for energy. This is a normal life process but sometimes can cause serious health conditions. Ketonuria is a common condition in individuals who have diabetes, particularly type 1 diabetes mellitus. It may also occur in pregnant women.
Additionally, if ketone levels rise above a certain bar then the blood may become acidic and harm the body.

Additional Information:
 Causes of ketonuria
-Ketogenic diet
Ketonuria is basically a sign from the body that only fats and protein are primarily consumed. It’s a normal process, if one is fasting or on a low-carbohydrate, ketogenic diet.
-Low insulin levels
Most of the energy that our body utilises comes from sugar or glucose which is found in carbohydrate rich food. Insulin is a vital hormone, produced in the body it transports sugar into every cell, including muscles, heart, and brain. The body cannot function efficiently without insulin. Therefore the body of a diabetic person finds another power source in which body fats and proteins are broken down for energy. Also ketones are produced as a waste product.
When too many ketones pile up in the bloodstream, the blood becomes acidic and this condition is called ketoacidosis or diabetic ketoacidosis. Major organs may also be harmed. Ketonuria usually occurs along with ketoacidosis.
So, the correct answer is ‘Diabetes mellitus’.

Note: Diabetes insipidus is a disorder of the body in which salt and water metabolism is marked by intense thirst and heavy urination. It occurs when the body fluids are not regulated. The condition isn't related to diabetes but caused by a hormonal abnormality.
