[|Human|] Can a soybean allergy cause blood in urine in a small child, he was diagnosed with a soybean allergy while he was on prosobee for a short time and it caused bloody stools, but we have never really paid much attention to what he eats with soy in it until lately when he complained of pain in groin area like a hernia pain but there is no hernia and no infection (UTI) culture was negative but he continues to have blood in his urine x 3 weeks now
[|AI|]  Hello. Thank you for asking at Chat Doctor. My first and practical answer to your query will be - No, food allergy can't cause blood in urine. As a doctor, I must let you know that there have been rare cases of food allergy causing hematuria (blood in urine) recorded in medical literature. But they are very, very rare. So practically, I would not consider soybean allergy causing blood in urine in your child. There are many causes commonly causing blood in urine in child Chat Doctor.  It is very important to diagnose and treat the cause. So personally I would suggest you to consult a Pediatrician who may suggest you some blood and urine investigations as well as ultrasonogram of genitourinary system which may help in diagnosis of the cause. Hope above answer solves your query. Wish your child a quick recovery and best of the health. Regards.
