Depending on the types of food eaten, food may begin to enter the bloodstream within moments. Proteins and fates take even longer to impact blood sugar. Meals that have appropriate portions of these various food components are usually the best for assuring blood glucose rises soon enough in relation to the medication taken, but yet does not rise to the extreme. When you use Humalog, it is important to begin eating soon so that insulin does not abnormally lower blood sugar before the food arrives in the form of glucose. For this reason, I recommend that the meal be started within five to ten minutes following an injection of Humalog.
Some people choose to begin eating even sooner than that.
Please check with your doctor before making any adjustments to your diabetes management program. I have Type 2 diabetes under tight control. About a year ago I fell and developed arthritis on my knee. This added condition leaves me in serious pain most of the time. My doctor is reluctant to prescribe medication for the arthritis because of the diabetes and advises me to take Tylenol.
