Which symptom is commonly associated with hypoglycaemia?

Confusion is a common symptom associated with hypoglycaemia because low blood sugar levels can lead to inadequate glucose supply to the brain. Glucose is a primary energy source for the brain, and when levels drop significantly, cognitive functions can be impaired, leading to confusion, mood changes, or altered mental status. This neuroglycopenic effect can manifest as difficulty concentrating, disorientation, or even changes in behavior.

In contrast, the other symptoms listed are not typically associated with hypoglycaemia. Dry skin is often linked to dehydration or certain medical conditions, high blood pressure can result from stress or other systemic issues, and frequent urination is commonly related to conditions like diabetes or urinary tract problems, but not directly to low blood sugar levels. Understanding the specific symptoms of hypoglycaemia can help in recognizing and managing this condition effectively.
