[Endocrine disorders associated with impaired glucose tolerance]

Area of Science:

• Endocrinology
• Metabolic Disorders

Background:

• Diabetes mellitus is a complex metabolic disease.
• Poor glycemic control in diabetes is linked to various endocrine dysfunctions.
• Understanding these endocrine changes is crucial for comprehensive patient management.

Purpose of the Study:

• To describe the endocrine disorders associated with diabetes mellitus.
• To detail specific hormonal abnormalities observed with deteriorating blood glucose control.

Main Methods:

• This study is a descriptive review of endocrine abnormalities in diabetes mellitus.
• It synthesizes findings on hormonal changes related to poor glycemic control.

Main Results:

• Elevated blood growth hormone (GH) levels disrupt insulin secretion and glucose metabolism.
• Decreased plasma insulin-like growth factor-1 (IGF-1) levels correlate with diabetic retinopathy.
• Thyroid hormone profiles resemble low T3 syndrome.
• Hyporeninemic hypoaldosteronism is observed, particularly in hypertensive diabetic patients.
• Plasma pancreatic glucagon levels are elevated, with abnormal responses to amino acids and glucose.
• Other pancreatic hormones like gastrin, secretin, motilin, and somatostatin show elevated plasma levels.

Conclusions:

• Deteriorating glycemic control in diabetes mellitus precipitates a range of endocrine abnormalities.
• These hormonal disturbances significantly impact glucose metabolism, insulin dynamics, and potentially contribute to diabetic complications.
• Further research into managing these endocrine dysfunctions in diabetes is warranted.
