What Causes Tiredness And Sleepiness After Eating?
Diabetes mellitus should be ruled
Hello and welcome
I appreciate your concern
Eating processed foods which contain refined carbohydrates, causes an initial rise and subsequent fall in blood sugar levels, which results in the picture which you described.
If these symptoms are bothersome and lead to affecting basic functioning then Fasting blood sugar and HBA1C levels should be done to rule out diabetes or glucose intolerance.
Wishing you best of health
