has to be surgically corrected
Thanks for writing to health care magic. Can you please share any information you already have about what kind of Heart defects and intestinal defects he is suffering from? Did the physician you took him to identify the syndrome for you?
To address these issues separately:
Hypospadias needs and will definitely improve with surgical correction. You will see the difference only after surgery. There is no other way of correcting it with medicines.
There are a number of syndromes affecting the heart and intestines along with hypospadias. Only a complete heart check and abdominal exam will evaluate and identify the syndrome. If you have that information, send it across to me and we can discuss in further detail.
Wishing him.speedy recovery
