Strict Blood Sugar Control After Heart Surgery May Not Be Necessary

Study results may encourage hospitals to consider more liberal blood sugar control policies Patients undergoing coronary artery bypass grafting (CABG) surgery may not have to follow a strict blood sugar management strategy after surgery, according to a study in the October 2014 issue of The Annals of Thoracic Surgery. Key points Liberal management of a patient's blood sugar levels following CABG surgery leads to similar survival and long-term quality of life as achieved through stricter blood sugar management. The findings applied to all patients, regardless of diabetes status. The results may encourage hospitals to consider more lenient blood sugar control in all patients after heart bypass surgery. Previous research has shown that hyperglycemia (high blood sugar) after CABG and other cardiac surgery is associated with increased morbidity and mortality; however, more recent studies have shown that liberal maintenance of blood glucose levels (<180 mg/dL) after CABG surgery can be safer and more advantageous in both diabetic and non-diabetic patients.

    I had outpatient (day) surgery yesterday. No food/drink from midnight until I was home around 5pm (no metformin in the morning either).
    Ate a typical for me dinner (with metformin) and headed to bed early (no evening snack)
    FBG this morning was 184 - YIKES
    had my metformin and a babybell cheese (0 carbs 5 protein) around 645
    retested and it's only down to 179
    I'm hungry but I'm afraid to eat because I don't want those numbers going any higher.
    I'm assuming that fasting yesterday and the surgery stress is why the numbers are so high? Is that logical?

    Most likely the high fbg was due to the stress of the surgery. See how your blood wugar is after a few days.

    The last time I had surgery, also after fasting, my BS was about 300. They gave me insulin and tested 15 minutes later, still high; repeat. I think they did this 3 or 4 times before deciding it was the stress and sent me home. Within a couple days my BS was back to acceptable levels.
