Question

why sometime sugar level in blood goes down drastically in diabetic petient

Answer 1

Hypoglycemia (low blood sugar) is uncommon in persons without diabetes. In otherwise healthy adults, fasting (lack of food) is the most common cause of low blood sugars. Medications such as insulin and drugs like alcohol are other primary culprits. Adults who are critically ill can also develop low blood sugars. In rare instances, hormonal disorders or tumors can be the problem. If for any reason you believe you are having symptoms related to low blood sugar that do not improve after eating, see a doctor for help.
