The body goes through metabolic and hormonal changes during pregnancy, with cortisol levels rising and insulin resistance increasing. Cortisol helps with fluid retention and regulating blood pressure, but this can make managing these factors more complicated during anesthesia. Higher cortisol levels can also affect how the body handles glucose, raising the risk of high blood sugar. Insulin resistance, mainly caused by human placental lactogen, leads to elevated blood sugar levels after meals and increases the chances of developing gestational diabetes. Because of this, anesthesia providers need to closely monitor glucose levels, especially during labor or surgery, to prevent complications.
For patients with insulin resistance or gestational diabetes, the stress of anesthesia can lead to stronger blood sugar fluctuations, either too high (hyperglycemia) or too low (hypoglycemia). Since general anesthesia can mask the symptoms of low blood sugar, it’s critical to monitor glucose levels carefully throughout the procedure. Maintaining stable glucose levels is crucial for the health of both the mother and baby. In some cases, neuraxial anesthesia (like epidurals) may cause blood pressure instability in diabetic patients due to changes in the body’s nervous system. By carefully managing glucose and monitoring it closely, anesthesia providers can help ensure a safe delivery and anesthesia experience.
