As your ferritin, vitamin d and iron levels are low without any reason it strongly suggests celiac disease but for proper disgnosis gene test,biopsy is required. You should consult competent gastroentrologist with good repute.
I am in search of competent gastroentrologist since 6 years and still searching.
Be sure to be on gluten free diet till biopsy but remember that gene test does not require to be on gluten free diet.
Welcome,I am always here for any suggestion or guidance. I am doing research on gluten free, celiac disease since 2015 but I am not diagnosed up till now. My nephew is diagnosed with celiac disease and I am also hopeful that I will be diagnosed soon.
If celiac disease is the cause of your reflux, it can take weeks, to months or a year for healing on a gluten free diet. I have celiac disease but only was anemic when diagnosed. Last year, I developed reflux for the first time. Another endoscopy determined that I had healed from celiac disease, but stomach biopsies revealed chronic autoimmune gastritis which slowly went into remission on its own after a many months. I assume my Gastritis will flare up again in the future. Unlike celiac disease where gluten is the trigger, the trigger for AI Gastritis is unknown.
To cope, I would sleep elevated and avoided eating late meals giving my stomach time to empty long before bedtime. I also reduced coffee and ate a bland diet.
Reflux is awful. I am so sorry that you are ill.
how fast after starting with gluten free diet did you notice any improvement with heartburn or reflux?
I am 4th day of diet and reflux seams to be worse than earlier. So I am a bit concerned.
