My 3 month year old son had his blood work done because he was losing weight and having trouble pooping. He was pooping every 2 to 3 days; once a day. Well, he was loosing weight because he had reflux. He had an X ray and he does not have pyloric disease. The doctor put him on Zantec and he is not throwing up. But, he had high liver enzymes when his blood was taken along with a high platelet count. Well, he got his blood work repeated and it went down and he s gaining weight now. But his platelet is still high. But, the doctor said since it s by it self not to worry, buy I am worried. What could be wrong with my 3 month old son? He passed his newborn screening and has no medical issues except reflux.
