What are the major symptoms of Diabetes Mellitus?

Correct option is D

The three main symptoms of Diabetes Mellitus are Polyuria (frequent urination), Polydipsia (excessive thirst), and Polyphagia (excessive hunger). These occur due to high blood sugar levels, which cause increased urine output, dehydration, and hunger due to impaired glucose utilization.
Explanation of Each Option:
· Polyuria (excessive urination): Common in diabetes due to increased glucose in the urine, leading to frequent urination.
· Polydipsia (excessive thirst): Occurs due to dehydration, as the body loses more water through urine.
· Polyphagia (excessive hunger): Happens due to insulin dysfunction, preventing glucose from being properly used as energy.
· All of the above: Correct answer; these three symptoms together indicate possible diabetes.
