Moderate to high-intensity exercises during the day or before sleeping:. People with tightly controlled blood glucose are more at risk of developing hypoglycemia than those with poorly controlled blood glucose levels. Factors that might lead to hypoglycemia among people who take insulin are: An imbalance in blood glucose levels and insulin levels might cause hypoglycemia.

Generally, hypoglycemia is when a person’s blood glucose levels fall below 70 mg/dl while sleeping. People who have prolonged hyperglycemia may develop symptoms of hypoglycemia even at blood glucose of 100 to 150 mg/dl.
