Final answer:
The symptom not associated with diabetes mellitus is C) Low blood sugar levels. Instead, diabetes is characterized by high blood sugar levels, leading to increased thirst, frequent urination, and increased hunger, alongside fatigue.
Step-by-step explanation:
All of the following are symptoms of diabetes mellitus, except:
- Increased thirst and hunger
- Frequent urination
- Low blood sugar levels
- Fatigue
The correct answer is C) Low blood sugar levels.
Diabetes mellitus is primarily characterized by high blood glucose levels, which lead to symptoms such as excessive thirst (polydipsia), frequent urination (polyuria), and increased hunger (polyphagia). Patients experience these symptoms due to the kidneys' response to high blood sugar, which involves filtering excess glucose and drawing water into the urine, causing dehydration and increased urination. Consequently, the body's cells do not receive proper glucose uptake, leading to persistent hunger.
Fatigue is another symptom often associated with diabetes due to the body's cells not receiving enough energy from glucose. However, low blood sugar levels, also known as hypoglycemia, are not a symptom of diabetes; rather, they can be a side-effect of diabetes treatment or a condition distinct from diabetes itself.
