Generally speaking, when hypoglycemia occurs, one should first correct the low blood sugar levels and identify the cause of the hypoglycemia before engaging in exercise. This is because hypoglycemia can manifest in various ways depending on the cause, the degree and speed of the blood sugar drop, and the individual's response. For instance, some patients may exhibit symptoms of excessive sympathetic nervous system activation, such as sweating, trembling, palpitations, hunger, anxiety, tension, and a slight increase in blood pressure.

If hypoglycemia is not corrected, it can lead to a further decline in blood sugar levels, resulting in symptoms of neuroglycopenia. These may include lack of mental focus, dizziness, sluggishness, blurred vision, unsteady gait, and even hallucinations, restlessness, abnormal behavior, and other psychotic manifestations. Some may also exhibit confusion, infantile movements, choreiform movements, and even some spasms, coma, and a drop in blood pressure. Therefore, hypoglycemia is a serious condition and exercise should only be undertaken after it has been corrected.
