She was seeking leach therapy for bluish, dilated and twisted varicose vein at the right poplitial fossa. She reported no history of diabetes mellitus on the past but on advice she did basic laboratory investigations prior to leach therapy i.e FBS, BT and CT. The blood report showed FBS of 220 mg/dl dated on 1st of March 2016. This patient was investigated as recently diagnosed case of diabetes mellitus and laboratory test was repeated 03/03/2016 to confirm diagnosis which revealed FBS of 201 mg/dl and PPBS of 240 mg/dl. Patient was advised not to take any allopathic medicine.
