Hi welcome to HCM I have gone thru your query regarding elevated BSL , It is a matter of concern and is very common problem these days . Do you know why ? Because of our faulty food habits and derailed life style and obesity is outcome and so is diabetes , hyper tension and other diseases . You have not mentioned your age and how old is your problem ?What alll you are taking in your diet ? You have told you are not taking extra sugar means still you are taking sugar ? with so high BSl ? You must keep in mind not to include sugar or sugary products , carbs in your diet . Constipation is mother of all ills . so be careful . Our health depends on what we eat ,when we eat and how we eat . and our activity level .
