Serious Medical procedure needed

Hi, my name is Brittany and I am the daughter of Rhonda Jackson. She has been a cancer survivor since 2014. For the last year and a half our mother has been fighting an iron deficiency. The doctors couldn’t figure out why her iron was 0. She has already had a minimal invasive procedure which was iron being injected into her through IV to increase her levels. Now 6 months later her iron is back down, her body isn’t creating the iron she needs. With various options of medication and diet change to increase it there is no improvement. She now needs a procedure an Upper Endoscopy for them to look internally to diagnosis the problem. Medical insurance will not cover the cost of the procedure. We are hoping anyone can donate anything, no matter the amount to help pay for this procedure she is desperately in need of. We appreciate any and all donations.
