What is one of the symptoms of hyperglycaemia?

One of the symptoms of hyperglycaemia, which is a condition characterized by elevated blood glucose levels, is often increased hunger. This occurs due to the body’s inability to transport glucose into the cells, leading to a feeling of starvation despite the presence of glucose in the bloodstream. When glucose cannot be utilized by the body's cells for energy, the body's response includes signaling hunger in order to prompt further food intake, hoping to meet energy needs.

The other options can be related to various conditions but may not specifically indicate hyperglycaemia. For instance, leg cramps might result from different issues, such as dehydration or electrolyte imbalances, while cold sweats and dizziness can be symptoms of a rapid drop in blood sugar levels, known as hypoglycaemia, or other medical conditions. Thus, the correct understanding of hunger as a symptom of hyperglycaemia helps reinforce the associations between glucose metabolism and physiological signals in the body.
