I sometimes feel sudden feeling of getting a 'high' and then it takes some effort to consciously focus on the surroundings. This is accompanied by shortness of breath. Sometimes heavy headedness is also experienced especially after a workout or a jog. I was feeling dizziness symptoms few days ago, have monitored diet and it has helped. My routine blood tests - cbc, lft, kft, thyroid profile, sugar fasting and post food, lipid profile, urine culture, vitamins D and b12, hba1c, and the result was fine! I have pcod, and anxiety. Could this be any serious? I have a hectic lifestyle and I am stressed mostly. I have recently made changes to my diet as well. Do I need to consult in person and undergo more tests?
