Thought I would update where we are with my son. We had his follow-up vist with the PA this past week. He has been on the iron supplement for 8 weeks now (we switched from the Floravital to Natural Factors Chewable tablets cheaper and easier to bring with us if we aren't home). He has since had 2 recurrences of the rash pictured above, including a flare now that the PA was able to see. She suggested it might be a dairy allergy and said we could try switching to soy products if we wanted (I don't at this time...I'm not comfortable with large amounts of soy, especially in children). He does not drink (cow's) milk, but does eat yogurt and cheese.
The suggestions at the end of the visit were to continue the iron supplement for 3 more months, consider adding zinc (she said the rash could also be a zinc deficiency?), and not to worry. She also said we really probably didn't need to return again, but could if we wanted to check the iron levels at the end of 2-3 months. I asked again why he would not be growing/why the vitamin deficiencies when he is not a picky eater, eats plenty of food for a toddler (including meat, which she had suggested could be why he was iron deficient since kids often don't like to eat meat...my son actually loves it and will eat entire chicken enchiladas, salmon filets, half an adult size burger, entire black bean burger, etc.). She said he may just be a small kid, but that we could check his stool for fat malabsorption if I would like. I am supposed to send in a sample sometime next week.
Since she is so unconcerned, I am honestly starting to feel a bit like a paranoid mama. To top it off, I also saw a GI doctor this past month (my symptoms: constipation since childhood, constant dull stomach ache...not painful, but achy if that makes sense, canker sores, white spots on my teeth and weak enamel, insomnia, tendonitis of the wrist, dizziness upon standing, pain under right ribcage that comes and goes, but takes my breath away when it comes--from my mom's experience, I am guessing it is gall bladder pain). Anyway, I was given a dx of IBS. The only symptoms that the GI was concerned with were the constipation and stomach ache. She did run a ttg IGA and serum IGA test (ttg IGA was negative, not deficient in IGA). After those tests were returned, I asked for the deamidated gliadin to be run, but she had never heard of it. She said she would look it up, but only ended up calling Labcorp for the code, which ended up being the code for the old gliadin test. I found the code myself on the Labcorp website, called it in to the GI, and she was kind enough to indulge me by resubmitting the lab order. All that, and they were negative (had both IGG and IGA done). Hence, my paranoia
