Which of the following is not a symptom of diabetes?

Weight gain is not a typical symptom of diabetes. Instead, the common symptoms associated with diabetes include frequent urination, excessive thirst, and tingling or numbness in the hands or feet.

Frequent urination occurs due to the body's attempt to eliminate excess glucose in the urine. Excessive thirst accompanies this frequent urination since the body becomes dehydrated. Tingling or numbness in the hands or feet can result from nerve damage related to prolonged high blood sugar levels.

While weight changes can occur with diabetes—some individuals may lose weight, particularly in type 1 diabetes due to insufficient insulin—weight gain is not a classic symptom associated with the condition itself. Rather, it can be influenced by other factors such as lifestyle, diet, or medications, but it does not directly correlate with the fundamental symptoms of diabetes.
