Which of the following symptoms is NOT included in the mnemonic for diabetes mellitus symptoms?

• A. Polyuria
• B. Polydipsia
• C. Palpitations
• D. Polyphagia

Answer: (C)

The correct answer is based on an understanding of the classic symptoms associated with diabetes mellitus, often summarized through the mnemonic "3 P's," which stands for polyuria, polydipsia, and polyphagia.

Polyuria refers to increased urination, a common symptom due to the kidneys' attempt to excrete excess glucose. Polydipsia denotes increased thirst, which results from the body's response to dehydration caused by the loss of fluids through frequent urination. Polyphagia indicates increased hunger, often stemming from the body’s inability to utilize glucose for energy, prompting an increased appetite.

Palpitations, while they may occur in individuals with diabetes due to various complications or issues such as hypoglycemia, are not one of the hallmark symptoms used to identify diabetes mellitus. Thus, this symptom falls outside the well-established triad recognized in the diagnosis of the condition. Understanding these symptoms is crucial for recognizing and managing diabetes effectively.
