Jonothon,
Thanks for your posted question. First of all, congratulations on getting your glucose levels down by adjusting your diet. Now, as to your change in blood pressure: there is no connection between your glucose levels returning to the normal range and a rise in your blood pressure readings. But your readings are elevated and need to be evaluated by your physician who will compare your readings to his/her findings in the office. If confirmed, he might initiate treatment now, or follow your pressure to be sure this is not just a temporary situation.
Please review this website for more information on high blood pressure and treatment.
Best wishes.
Martin Cane, M.D.
