What is a common physical sign that someone may have diabetes?

Unexplained weight loss is a significant physical sign that someone may have diabetes, particularly type 1 diabetes. This weight loss often occurs because the body is unable to utilize glucose properly for energy due to a lack of insulin or insulin resistance. Consequently, the body begins to break down fat and muscle for fuel, leading to weight loss that is not attributed to changes in diet or exercise.

In the context of diabetes, this symptom serves as a critical indicator; it is essential for individuals experiencing such weight changes, alongside other symptoms, to seek medical evaluation for possible diabetes. This understanding is crucial in promoting awareness of diabetes signs, enabling timely intervention, and managing the condition effectively.
