Question

Write briefly about the symptoms of diabetes mellitus.

Answer 1

The symptoms of diabetes mellitus result from high blood sugar levels and include:

• Excessive thirst (polydipsia), as the body attempts to compensate for high blood sugar by drawing water from tissues.
• Frequent urination (polyuria), because the kidneys work harder to filter and excrete the excess sugar.
• Increased hunger (polyphagia), as the body's cells are starved of energy due to insufficient or ineffective insulin.
• Unexplained weight loss, particularly in Type 1 diabetes, as the body begins burning fat and muscle for energy.
• Fatigue and blurred vision, caused by the body's inability to effectively use glucose for energy and the effects of high sugar levels on fluid balance.
