Hypoglycaemia refers to low blood sugar levels, which can be potentially dangerous. This condition occurs when the glucose levels in the bloodstream drop below normal, leading to symptoms such as weakness, sweating, confusion, and in severe cases, loss of consciousness or seizures. It is often associated with diabetes, especially when patients take insulin or certain medications that lower blood sugar.

When blood sugar levels are critically low, the body is deprived of the essential energy it needs to function properly, particularly affecting the brain and nervous system. Therefore, recognizing and treating hypoglycaemia promptly is crucial to prevent serious health complications.

The other options describe various conditions that do not align with the definition of hypoglycaemia. For instance, high blood sugar levels refer to hyperglycaemia, while severe dehydration indicates a lack of sufficient fluids in the body. A type of stroke caused by sugar imbalance is also not a recognized medical condition. Understanding hypoglycaemia is essential for providing effective first aid and managing health, especially in individuals with diabetes.
