Which hormonal deficiency is likely to cause an accumulation of reducing sugar in the urine?
Answer Details
Insulin is a hormone produced by the pancreas that helps to regulate the level of glucose (sugar) in the blood. When insulin is deficient or absent, as in the case of type 1 diabetes, the body cannot properly regulate the level of glucose in the blood. This can lead to an accumulation of glucose in the blood, which can then spill over into the urine.
However, the question is asking about the accumulation of reducing sugar in the urine, not glucose. Reducing sugar is a term used to describe sugars that have a free aldehyde or ketone functional group, which allows them to act as reducing agents. Glucose is a reducing sugar, but so are other sugars like fructose and lactose.
In certain hormonal deficiencies, such as those caused by tumors in the pancreas or adrenal glands, there can be an excess of hormones that stimulate the breakdown of glycogen (the stored form of glucose) into glucose. This excess of glucose can overwhelm the ability of the kidneys to reabsorb glucose, leading to glucose being excreted in the urine. In addition to glucose, the breakdown of glycogen can also produce other reducing sugars, such as fructose and lactose.
Therefore, the hormonal deficiency that is likely to cause an accumulation of reducing sugar in the urine is a deficiency of insulin, as seen in type 1 diabetes.
