Geez, Louise! Where is the doctor in this situation? Honey is SUGAR! Sugar raises blood glucose levels. Raised blood glucose levels damage EVERY cell in the body.
Honey is to be avoided at all costs. If you father has a low blood sugar reading and needs to bring it up quickly, he should resort to either a glucose tablet or 4 oz of orange juice. Check his blood sugar 15 minutes after taking either of those 2 things, if it's still not coming up, take 4 more oz of orange juice or another glucose tablet. Wait 15 more minutes and check his blood sugar again. If it's still low, call the doctor.
Low blood sugar is a dangerous condition. It can easily translate into a coma and/or death. If his blood sugar is dangerously low, he should call 911 before he passes out - after would be just a tad to late. I am not being funny - diabetes is a serious illness and it is amazing to me how many people treat it like it was a headache or something.
Read about it, there are things you can do to control this illness. One of the best books I ever read was, "Diabetes Solutions Updated and Revised" by Richard Bernstein, M.D. It changed our lives!
