Physiological Effects of Insulin Deficiency

The human body relies on complex regulatory mechanisms to maintain homeostasis. The endocrine system plays a crucial role in this process by secreting hormones that regulate various physiological functions. For example, insulin is a hormone produced by the pancreas that lowers blood glucose levels, while glucagon raises it. The interaction of these hormones is essential in metabolic control. Consider a scenario where an individual has consistently high blood glucose levels due to insufficient insulin production. This condition, known as diabetes mellitus, disrupts normal bodily function.

Based on this context, which of the following statements accurately describes a physiological change that occurs in the body when insulin levels are inadequate?
