My baby is 2 month old. He was suffering from forcefully vomiting. After usg surgery done on 30th september, 19.doctor said surgery successfully done. After surgery everything is normal. But last one week he is suffering from mild vomiting /spit up after eating. Before surgery he was 3.5 kg and now he is 4.8 kg.before 3 days I was consulting with pediatric surgeon. He said no problem. But after eating every time spit up. Now what can I do? Need any further usg for recurrent pyloric stenosis? Is usg effect on tummy area badly after surgery.
