Final answer:
The statement from the student is false because excessive urination in Diabetes Mellitus is caused by hyperglycemia-induced diuresis, not by inadequate ADH levels which is actually characteristic of Diabetes Insipidus.
Step-by-step explanation:
The statement provided by the student can be confusing as it mixes up the symptoms of two different types of diabetes. In Diabetes Mellitus, excessive urination, also known as polyuria, is primarily caused by high levels of glucose in the blood, which lead to water being pulled into the urine. This results in a large quantity of dilute, glucose-rich urine. The excessive blood glucose overwhelms the kidneys' capacity to reabsorb glucose, leading to osmotic diuresis. On the other hand, Diabetes Insipidus is due to inadequate secretion of Antidiuretic Hormone (ADH) from the posterior pituitary or a mutation in the ADH receptor, not Diabetes Mellitus. In Diabetes Insipidus, ADH's function to retain water in the kidneys is impaired, leading to the excretion of large volumes of dilute urine and the consequent need for increased fluid intake.
Thus, the statement is False because Diabetes Mellitus is not caused by inadequate ADH levels, but Diabetes Insipidus is. The loss of water in Diabetes Mellitus is due to the kidneys filtering out excess glucose, which carries water along with it, while in Diabetes Insipidus, it's a direct result of ADH deficiency affecting the kidney's ability to concentrate urine and retain water.
The statement is false because excessive urination in Diabetes Mellitus is due to osmotic diuresis caused by high glucose levels in blood, not inadequate ADH which is associated with Diabetes Insipidus.
