The low diabetic range is any amount below 70 milligrams of glucose per deciliter of blood, according to MedlinePlus. A blood sugar level in this range can cause health issues.
The risks associated with having a low diabetic range increase with the overdose of insulin or diabetic medicine, taking diabetes medications at the wrong time, excessive exercise and drinking alcohol, explains MedlinePlus. Patients with low blood sugar should check their blood sugar regularly.
The symptoms of having a blood sugar level in the low diabetic range include sweating, tiredness, headache and a feeling of nervousness, according to MedlinePlus. To prevent low blood sugar level, a patient should exercise when it is appropriate, avoid taking alcohol before eating and consult a doctor about reducing insulin on the days of exercise.
