What signs may indicate poorly controlled diabetes?

The signs of increased thirst and frequent urination are commonly associated with poorly controlled diabetes, primarily due to the body’s attempt to manage elevated blood glucose levels. When blood sugar levels rise significantly, the kidneys work to filter out the excess glucose, leading to an increased volume of urine. This process can cause dehydration, triggering not only frequent urination but also increased thirst as the body tries to replenish lost fluids.

In poorly controlled diabetes, hyperglycemia is a significant concern. The body's inability to properly utilize insulin results in elevated blood sugar levels, contributing to these symptoms. The increased thirst and urination are classic signs of diabetes that should prompt further assessment and management strategies to improve glycemic control.

While the other options present symptoms that could be related to diabetes, they do not draw the direct connection to poor blood sugar control in the way that increased thirst and frequent urination do. For instance, increased appetite and weight gain may occur in certain scenarios but are not definitive indicators of poor diabetes management. High energy levels and clear vision typically reflect well-controlled diabetes, while frequent headaches and dizziness could stem from various other causes, making them less specific indicators for diabetes management issues.
