Is it possible to develop low blood sugar without being diabetic? how is low blood sugar treated?

A person can develop low blood sugar without being diabetic. The plasma glucose level below 40 mg/dL is considered low and would require administration of sugar, preferably glucose. Fruit juice, and sugar are usually adequate. For info: https://www.mayoclinic.org/diseases-conditions/hypoglycemia/symptoms-causes/syc-20373685#:~:text=Hypoglycemia%20is%20a%20condition%20in,who%20don't%20have%20diabet

Find the cause and treat that. Diabetes usually causes high blood sugar not low unless you are taking to much diabetes meds.
