I had gastric sleeve surgery and am experiencing low blood sugars in the 50's & 60's. I feel I am eating properly high protein/complex carbs?

Recovery support. It is possible you will auto regulate and these episodes will become less dramatic and less frequent. The surgery you had is a sudden change, ie decrease in the size of your stomach. The endocrine response to food may change more slowly. In the meantime, discuss with your doctors, monitor your blood sugars and eat a small amount of food more frequently. Be well.
