Your son may have got your disorder through his genes. We have heard of it running through generations in the same family. It use to be before the medical community noticed our disorder we all hid it from most everyone we know including our doctors. Not anymore it has a name and it's official ARFID Avoidant/Restrictive food intake disorder. It might be a good idea to get some tests to see if you are deficient in anything. If you are then you need to find some supplements or identify foods you can eat that will help fix the deficiency. Your doctor is there to listen and help you be the best you can be. If you do not get any real help from your current doctor than I would look for a doctor who is interested in helping you. It could even be a teaching moment for your doctor when you educate him about ARFID. He may have had other patients with it and he didn't even know it. Bob K
