Hello, Thanks for the query. Sometimes when blood glucose levels are controlled strictly, or if a person is on Insulin injections or on certain sulfonyl ureas, there's a possibility of developing hypoglycemia. In such situations it is necessary to make the person aware of hypoglycemia symptoms like sweating
on forehead, face, blurring of vision, weakness, cloudy feeling, unable to think clearly, giddiness, shivering feeling etc. On the appearance of any of these symptoms, he or she should take some candy or gluco tabs, which replace glucose. Severe hypoglycemia is very detrimental to heaith. If need be drug dosage and eating pattern should also be looked at. Thanks.
