Hello Catherine
I will be brief - although my answers could be extensive.
My advice - return to your original surgeon ASAP - he/she may be able to go in simply - on the principle of a stitch in time - depends on your situation.
Best advice: ring your hospital team directly - rather than wait for a re-referral - dependent upon your original presenting symptoms, you may get a faster solution in this manner.
Edit:
I agree with the two next replies... The bottom line is DO NOT LIFT ANY WEIGHT - including grocery shopping, etc. It does not have to be a mega heavy weight to cause a push through - because once a stoma is formed, in effect that is the first 'weakness' where the muscle is cut and thus subsequent pressure on the abdominal wall can so very easily cause a/further hernia/s.
Even when a series are repaired surgically, using reinforcing mesh, a section of our remaining gut can push through where the stoma exits... and so the KEY IS CONSERVATIVE MANAGEMENT - if you can feel a resistance upon an attempted lift of anything - DON'T LIFT IT!
... And yes, we all think, it will be OK just this once if I am careful... BUT it's easy to think I told you so / I knew I shouldn't have lifted that! ... By then the damage is done and so it is, that a high percentage of us have a hernia - so be warned and be very very kind to yourself - only lift a kettle!
Hope this helps.
Good luck
Best wishes
