I am writing on behalf of my best friend so I won't get every detail perfect but here goes a try..
8 year old boy just diagnosed with kidney stones. This child has a history of every food intolerance known. Trouble started in infancy with severe reflux, followed by eating issues facililitating the use of a feeding tube at 20 months. His food allergies are not all classic- some show as gastro symptoms, some as redness, rashes etc. He does not eat dairy, gluten, soy, nuts, seafood, eggs, berries. So his diet is limited but his mom is a allergen-free chef and owns a shop devoted to allergy free food so he is getting mostly homemade, whole foods- although he does eat a lot of sugar (IMO)
He takes probiotics and calcium.
other health issues- hospitalized with pneumonia, eye muscle that gets "stuck"- not really sure what that is but he has been helped with a homeopathic remedy., seasonal allergies,
I don't think she has explored the Sals.histamine idea.
this child has been to a naturopath, homeopath, holistic md, regular md's, specialists, you name it.
Through it all- he is an amazing athlete and a very smart little boy.
