Final answer:
All of the options listed (high blood glucose, glucose in urine, excessive thirst, and large excretion of urine) are correct symptoms associated with untreated diabetes mellitus, which is a condition where the body cannot properly regulate blood sugar levels.
Step-by-step explanation:
The question is related to the symptoms experienced by individuals who have untreated diabetes mellitus. In such individuals, blood glucose levels are typically very high due to the body's inability to produce sufficient insulin or because cells do not properly respond to insulin. This condition causes glucose to be present in the urine (glycosuria) because the kidneys cannot reabsorb all the glucose filtered from the blood.
Additionally, the high concentration of glucose in the urine draws water with it, leading to a large volume of urine and frequent urination (polyuria). This diuretic effect results in excessive thirst (polydipsia) because the body becomes dehydrated. The affected person may also experience persistent hunger because the body's cells cannot access the glucose they need from the blood, leading to feelings of fatigue and weakness (polyphagia).
Therefore, the correct answer to the student's question on the manifestations of untreated diabetes mellitus is E- All of the answers are correct.
