I have hypertension and am on medication since two years and taking Tenolol 25 MG and telmed AH once a day. I check BP regularly and it is always normal. I am physically active and do one hour of swimming or walking a day regularly and also do trekking occasionally. All other reports i.e lipid profile, ECG, Stress Test are normal. Creatinine is 1.34. I was earlier diagnosed as pre diabetic and HBA1C in may 2017 was 6.3. Not taking any medicines for sugar. Since 3 months my FBS is around 150 and post prandial sugar is around 210. However I do not experience fatigue or weakness. Do I need to start taking medicines for diabetes?
