Which symptom is NOT associated with Diabetes Mellitus (DM)?

Lethargy is a symptom that can be associated with various conditions, including infections, hypothyroidism, and even psychological disorders, but it is not a direct hallmark of Diabetes Mellitus. Individuals with DM typically present with symptoms related to high blood glucose levels, which include increased thirst, frequent urination, and increased hunger, among others.

Increased urination, also known as polyuria, occurs because the kidneys attempt to eliminate excess glucose from the blood by excreting it in urine, which leads to increased urine production. Flushed skin can sometimes occur due to various factors, including infection or dehydration, and is not a standard symptom of diabetes. Tachycardia, or rapid heartbeat, might be observed in certain instances, especially in the context of dehydration or as a response to other metabolic disturbances related to diabetes.

Understanding these symptoms' contextual relevance helps differentiate which are directly associated with Diabetes Mellitus and which may arise from other medical issues.
