Sorry need a lot more info to help. If her BG is low she needs to talk to the MD that gives her her diabetes medication. she be on too much meds.
things that efect BG (the big thing)
carbohydrates (ALL carbs raise BG)
medication
exercise
illness
infection
pain
stress
weight
plus much more
chainge any one of them and BG chainges
IE if she looses weight she will need to reduce here meds
what meds are she on? how old is she? it does not sound like she tests her BG. If she is on a med that will lower BG SHE needs to check her BG regularly.
Thanks for using the forum.
A blood sugar of 50 as you know is too low. Your mom's friend may need to have changes made in her medication. She may be able to decrease some of the meds and still maintain a stable blood sugar. This should only be done with the advise and supervision of her doctor.
