From past 2/3 months I am getting severe symptoms of hypoglycemia if I skip meals and even after 2/3 hours of eating and it happening daily...Symptoms are coming even when my blood sugar level is above 70 as I checked it on glucometer during symptoms and the reading were 77,82,85,75 after 3 to 4 hours and 105, 107 after 30mnts of eating..Symptoms include excessive hunger and sweating, confusion, blurry vision, anxiety, heart palpitation, cold hand and feet, feeling of fainting or falling down, dizziness etc and the symptoms goes away once i eat something..Its happening from past 3 months on daily basis..Diabeties and thyroid test done twice and its normal..H1bac is 5.5, Lft,Kft,cbc, Lipid,vit b12 are normal..Mild fatty liver and Vit D3 deficiency 6.58...Is there any test to confirm whether I really have hypoglycemia and IS THERE ANY PERMANENT CURE FOR THIS...Please reply
