Hi,
Welcome to Health Care Magic, Thanks for writing to us,
I am Dr.Ahmad Bilal, I have read your question, I understand your concern and will try to help you in the best possible way.
There are few skeletal abnormalities which can be there if there is lack of some
vitamins minerals Specially calcium in childhood.
This might well be the case with your brother,
If this is just a mild issue, he is functioning well ,breathing well,
then there is nothing to be worried about.
All he has to do is to take regular vitamins and calcium most preferably through good and balanced food.
I will also suggest him to stay involved in good physical activity which will help him get strong and allow his body to function well with that abnormality.
There should not be any problem in future plus it doesn't seem to be a severe issue because he never felt it before he got an X-ray.
So it shouldn't be taken as an alarm and things should go normally.
I Hope this answers your question, if your have more queries feel free to ask,I will be pleased to alleviate your concerns.Wish you the best of health.
Regards,
Dr.Ahmad Bilal
