These symptoms tell you that you your blood glucose is low and you need to take action to bring it back into a safe range. But, many people have blood glucose readings below this level and feel no symptoms. This is called hypoglycemia unawareness. Hypoglycemia unawareness puts the person at increased risk for severe low blood glucose reactions when they need someone to help them recover. People with hypoglycemia unawareness are also less likely to be awakened from sleep when hypoglycemia occurs at night. People with hypoglycemia unawareness need to take extra care to check blood glucose frequently.
This is especially important prior to and during critical tasks such as driving. A continuous glucose monitor can sound an alarm when blood glucose levels are low or start to fall. This can be a big help for people with hypoglycemia unawareness. If you think you have hypoglycemia unawareness, speak with your health care provider. This helps your body re-learn how to react to low blood glucose levels. This may mean increasing your target blood glucose level a new target that needs to be worked out with your diabetes care team. It may even result in a higher A1C level, but regaining the ability to feel symptoms of lows is worth the temporary rise in blood glucose levels.
This can happen when your blood glucose levels are very high and start to go down quickly. If this is happening, discuss treatment with your diabetes care team. Your best bet is to practice good diabetes management and learn to detect hypoglycemia so you can treat it early—before it gets worse.
Monitoring blood glucose, with either a meter or a continuous glucose monitor CGM , is the tried and true method for preventing hypoglycemia. Studies consistently show that the more a person checks blood glucose, the lower his or her risk of hypoglycemia. This is because you can see when blood glucose levels are dropping and can treat it before it gets too low. Together, you can review all your data to figure out the cause of the lows. The more information you can give your health care provider, the better they can work with you to understand what's causing the lows.
Your provider may be able to help prevent low blood glucose by adjusting the timing of insulin dosing, exercise, and meals or snacks. Changing insulin doses or the types of food you eat may also do the trick.

There are the slow lows, where blood sugars drop ever so slightly over time until you are symptomatic. These are the ones that make me feel weak, shaky, nervous, not want to talk to anyone, and give me a ravenous need to eat everything around me until I feel better. I hate this feeling. I do like that he will bring me a juice box or something to treat at night. It helps to have a little bit of the burden shared by someone else.

Additionally, when a glucose value is in the hypoglycemic range, the accuracy is further decreased [ 47 — 49 ].
Caregivers using these devices need to be educated about their limitations and a value that is not consistent with the clinical picture needs to be verified by a central laboratory method. Currently no evidence-based guidelines exist regarding when to cancel a surgical procedure due to hyperglycemia. Given the multitude of patient factors involved as well as the variety of surgical procedures and procedure urgency, it is unlikely that recommendations based on outcomes will be forthcoming.

Providers need to weigh several issues when considering this question. First of all, the urgency of surgery should be considered. Secondly, hyperglycemia could represent an unstable metabolic state, such as diabetic ketoacidosis, which should be rapidly assessed in the preoperative area.

Elective surgery in unstable metabolic state is not recommended. Furthermore, the chronic glycemic state of the patient should be considered. In this situation, there are opportunities for providers to identify and address the problem prior to the patient arriving in the preoperative area. Another consideration is that the hyperglycemia may be caused by the illness for which the patient presented for surgery for example, osteomyelitis , which would not be expected to improve until the patient undergoes surgery.
Providers need, therefore, to assess the patient for stability, the need for the procedure, the risks of the procedure, and the ability of the patient to achieve glucose control if the surgery is postponed. At Yale New-Haven Hospital, no cutoff value to trigger evaluation for ketoacidosis has been set.
It has been left to the discretion of the physician. The multidisciplinary nature of a perioperative protocol necessitates education over the course of time and in different formats. At Boston Medical Center, this included surgical and anesthesiology grand rounds to review data and recommendations and later a joint conference regarding the practical implementation of the protocol.
There were nursing in-services as well as training in the use of glucose meters and point-of-care testing with ketostix. Nurses without prior ICU experience also needed training in insulin infusion administration.

At all steps, the physician groups were given updates at conferences and via emails. We also developed an educational video that was available for viewing on the hospital intranet. The endocrinology team was trained in the protocol to provide support when issues arose. In order to assess the safety of our protocol and to identify unforeseen issues, a three-month pilot of the protocol was performed in one OR area prior to it being used hospital wide. The leadership group focused on the efficacy at achieving glycemic control and the incidence of hypoglycemia, as well as any needed adjustments to nursing orders before deciding to expand the program.
Pilot results have been previously published [ 50 ]. At Yale New Haven hospital, similar education was employed, and an initial protocol was tried in the cardiothoracic ICU and then introduced to the perioperative services. We are in the process of analyzing the data for our in-hospital population. Table 2 summarizes the main challenges that arose during the creation and implementation of these protocols and how they were addressed.
There is currently a lack of evidence to guide providers regarding the details of perioperative glycemic management. We provide this information to report our experience and inform the literature, not as a formula we wish to recommend as the ideal or only way to approach the issue. Below, we describe the patient flow that occurs at each of our institutions for an example patient.
A comparison of the two programs is provided in Table 3. The endocrinology and preoperative clinic have created a standard guideline to adjust medications prior to surgery Figures 1 and 2. All patients undergoing surgery automatically have an order for perioperative glycemic control in our computerized system cuing the nurse to start the protocol. Upon arrival, the nurse in the preoperative area will check a glucose level on all patients with diabetes.
The anesthesiologist is made aware of the treatment in the preoperative area. The infusion is included as part of the presurgical WHO checklist to assure all staff are aware of the therapy, and the anesthesiologist continues insulin titration according to the protocol in the operating room.
On arrival in the postanesthesia care unit, the endocrine fellow is paged. The fellow provides recommendations for a subcutaneous insulin program while in the hospital. For patients with type 1 diabetes or patients on an insulin pump, the endocrinology fellow is paged prior to surgery. It should be noted that it took one year for our multidisciplinary team to create the protocol, ensure the necessary equipment, and perform the needed education prior to the three-month trial pilot.
After this, adjustments were made to the protocol, the education was expanded, and it took nine months before the protocol was used hospital wide.
