KEY MESSAGE Diabetes and high blood pressure are often clustered together Many people with undiagnosed type 2 diabetes have high blood pressure Good control of blood pressure can substantially reduce your risk of developing cardiovascular complications such as heart attack and stroke You can help lower your blood pressure by reducing the amount of salt in your diet by choosing to eat fewer processed foods and foods high in salt such as processed meat cheese and salty snacks CANRISK USER GUIDE FOR PHARMACISTS 9 10 QUESTION 8 High Blood Sugar Have you ever been found to have a high blood sugar either from a blood test during an illness or during pregnancy O Yes 14 points O No or don t know 0 points AX Tips This question measures if patients were ever told their blood glucose was high or abnormal even once regardless of whether they have been given medications If your patient had their blood glucose tested but did not have an abnormal result then they should answer no e This question presumes that the person being assessed has never been diagnosed with diabetes but may have had gestational diabetes or a one time abnormal result during an illness etc Your patient should answer yes if they have ever had one or more high blood glucose readings Oe KEY MESSAGE Previous test results indicating abnormally high blood sugar are an indication of temporary metabolic problems or poss
