Explanation:
The normal fasting blood sugar range is 70 to 1 00 mg/dl. Any individual with a blood sugar level less than 60 mg/dL is suspected to be hypoglycemic. The most important cause of hypoglycemia in type 1 diabetes mellitus is mismatch between insulin dose and insulin requirement.
The patient in this case had hypoglycemic episodes during exercise due to a decreased requirement of insulin during exercise. The patient needs to adjust his insulin dosage or consume more carbohydrate. The target pre-meal blood sugar level in patients with diabetes is between 80 and 120 mg/dl. The action is generally necessary if the pre-meal blood sugar is consistently less than 80 or more than 140 mg/dl.
