Hyposecretion of insulin causes diabetes mellitus.

Question

Hyposecretion of insulin causes diabetes mellitus.

BlackTom AI · Accepted Answer

The statement presents a binary true/false claim: Hyposecretion of insulin causes diabetes mellitus.

First, consider what happens when insulin levels are insufficient. Insulin is the hormone that facilitates cellular uptake of glucose from the bloodstream into tissues such as muscle and adipose tissue. When insulin secretion is reduced (hyposecretion), glucose remains in the blood, leading to chronic hyperglycemia, which is the defining feature of diabetes mellitus.

In types of diabetes, the underlying mechanism often involves impaired insulin production. For example, in type 1 diabetes, autoimmune destruction of pancreatic beta cells leads to little or no insulin production, i.e., hyposecretion relative to normal needs, which causes diabetes.

Additionally, diabetes can arise from partial insulin deficiency or relative insulin deficiency in combination with insulin resistance (as seen in some cases of type 2 diabetes or gestational diabetes), but the core idea remains that insufficient insulin activity contributes to the hyperglycemia characteristic of diabetes.

Finally, it is worth contrasting with the opposite scenario: excessive insulin secretion would tend to lower blood glucose and could cause hypoglycemia, not diabetes, highlighting why the insulin-deficiency mechanism is the diabetes-associated pathway.

Therefore, given the role of insufficient insulin in producing the persistent hyperglycemia that defines diabetes mellitus, the statement is correct.
