What are some common symptoms of diabetes?

Increased thirst and frequent urination are hallmark symptoms of diabetes. This occurs primarily because, in diabetes, levels of glucose in the blood become elevated. The kidneys work to filter out the excess glucose, leading to increased urine production. This, in turn, causes the body to lose fluids, prompting an increase in thirst as the body attempts to replenish lost fluids.

These symptoms help in identifying diabetes, particularly the more prevalent forms such as type 1 and type 2 diabetes. Recognizing these signs is crucial because they can lead to prompt diagnosis and management of the condition, preventing more severe complications in the future.

While other symptoms listed in the options may occur under different medical conditions, they are not specific to diabetes. For instance, chest pain and difficulty breathing could indicate heart problems and dizziness or excessive sweating may relate to various issues, including low blood sugar or anxiety, but they do not specifically point to diabetes. Increased appetite and weight loss can also occur in diabetes, particularly type 1, but they are less prominent than increased thirst and frequent urination. Thus, option B distinctly captures essential and direct symptoms commonly associated with diabetes.
