What symptom is NOT typically associated with type 1 diabetes mellitus?

Severe hypertension is not a typical symptom associated with type 1 diabetes mellitus. In type 1 diabetes, symptoms usually arise from the body's inability to produce insulin, leading to elevated blood glucose levels.

Increased thirst, also known as polydipsia, is a common symptom as high glucose levels can lead to dehydration. Weight loss often occurs despite normal or increased eating because the body starts to break down fat and muscle for energy when it cannot use glucose effectively. Nocturia, or frequent urination at night, frequently happens due to the increased volume of urine produced when blood glucose levels are high, causing the kidneys to attempt to eliminate the excess glucose.

Severe hypertension is not a defining symptom of type 1 diabetes but could be associated with other conditions or later stages of diabetes-related complications.
