Hello and welcome to HCM,
Natural fruit juices especially citrus fruit juices contain ascorbic acid
It may be causing the hemolysis
of RBCs in your son.
So, stop all these foods which contain the items contraindicated in G-6-PD deficiency.
The list of food items contraindicated in G-6-PD deficiency can be procured from the internet.
Stay in touch with your hematologist
Thanks and take care
Dr Shailja P Wahal
