I am experiencing dizziness, weakness, fatigue, exercise intolerance since last 15 months when I exercised more with reduction in calories intake (low carb diet). I had stopped this program 10 months ago and have LFT, KFT,SERUM ELECTROLYTES, TOTAL PROTEIN, SERUM CORTISOL (7.95 ug/dl) blood test all of which are in Normal ranges except blood sugar levels. One thing more is that my weakness, fatigue increase in early morning and in late evening. Here are some levels of my blood sugar F:- 74,69,66,71,70 PP:- 84,81,78,76,74 I had my insulin levels checked which again came normal. I remember correctly that just 2 months before the starting dieting program my sugar levels are F:- 89,87,88 PP:-98,99 please help me as this problem is destroying my career.
