Get checked ...: Non-Diabetic Hypoglycaemia can happen in certain medical conditions, hypothyroidism, or gastrointestinal disease causing malabsoprtion. Most people get a mild degree of low blood sugar a few hours after eating, this may be exacerbated if eating highly refined carbohydrates. https://www.drugs.com/cg/non-diabetic-hypoglycemia.html appears to have a sensible summary. See your Dr to discuss.

Hormones: I see that you take thyroxine. Please see your doc. Perhaps that needs to be adjusted. Please don't do that w/out seeing doc. He/she may also give you an A1C lab test which will give you a better idea about diabetes than a fasting glucose. Peace and good health.
