Thank you very much for your enquiry to the forum which I have read with interest.

First of well done on giving up smoking and as you mention in your letter it is quite common following children to gain excess weight in the tummy area and develop slightly loose muscles  in this region.

From your letter I was not quite clear whether you had had a tummy tuck procedure and if you have not, I think a tummy tuck (Abdominplasty) with repair of the muscles would be the ideal procedure for you.

Before the surgery it would be best to loose the excess weight, the few kilograms you have put on.

On balance I think it would be best to have a consultation with  a surgeon to discuss an Abdominoplasty at which they can show you before and after pictures and explain the pros and cons and possible complications in your case.

Overall, as I mentioned well done on giving up smoking and good luck if you do decide to go ahead with surgery.
