Question

Diabetes mellitus is characterized by

• A. Increase of sugar in blood
• B. Increase of sugar in urine
• C. Decrease of sugar in blood
• D. Both A and B

Answer 1

The correct option is D Both A and B

Diabetes mellitus occurs when there is increased levels of sugar in blood and this condition is called hyperglycaemia. This disorder is caused due to deficiency or low secretion of insulin hormone. Insulin is secreted from the β cells of islets of Langerhans of pancreas. Insulin acts on hepatocytes and adipocytes and increases the uptake of cellular glucose and its utilisation. This leads to movement of glucose to hepatocytes and adipocytes from the blood, thereby resulting in the decreased blood glucose levels.

Hence, due to low insulin levels in diabetes mellitus, there is increased sugar in blood and urine.

Thus, both options A and B are correct.

So, the correct answer is 'Both A and B'.
