I am around 60, a retired airline personnel. I never had high blood sugar but sometime in the border but could be diet controlled as per doctor. But about 3 months back I had lost weight by about 10k and reduced my waist measurement too. When checked, the blood sugar was above 500 and I became scary. But since medication is a must which I wanted to avoid, I started walking and stopped sugar and sweet completely from my diet. Later when checked, I found the sugar level (FBS) higher than 300 and again after a few weeks it was found to be 224. What could be the reason for the abnormal rise and fall in blood sugar. During this period I was going through some tension too.
