Answer 1

Individuals with diabetes mellitus drink more water due to dehydration caused by high blood sugar levels. The excessive glucose acts as an osmotic diuretic, which leads to frequent urination and subsequent dehydration, triggering the body's thirst response.

Step-by-step explanation:

People with diabetes mellitus often drink a lot of water due to increased blood sugar levels leading to dehydration. When blood glucose levels are high, the kidneys filter more glucose into the urine. This excess glucose in urine acts as an osmotic diuretic, pulling water with it and causing frequent urination, a condition known as polyuria. Consequently, the body becomes dehydrated, triggering the thirst response and resulting in polydipsia, which is an excessive intake of water. This process is part of the body's attempt to regulate high blood glucose levels and prevent further dehydration.

Option A, "Due to increased blood sugar levels leading to dehydration," is the correct answer. The body's physiological response to elevated glucose levels, described by the three 'Ps' - polyuria, polydipsia, and polyphagia, explains the excessive thirst experienced by individuals with diabetes mellitus.
