Most doctors now do gastric sleeves through keyholes - it is far less invasive and quicker to heal (and hurts a hell of a lot less!)
I was lucky - I had four keyholes, one of which was tiny, the other three have 4-5 staples sealing each, together with surgical glue.
Most people have between three and five keyholes, some a few more if they are also having their gall bladder removed or hernias fixed.
Fixings vary - from staples, dissolvable stitches, glue and steri-strips - you could have just one, or a combination deal, all depending on the tastes of your surgeon.
I was lucky - I had four keyholes, one of which was tiny, the other three have 4-5 staples sealing each, together with surgical glue. I have hardly any bruising, which makes me very grateful to my surgeon.
Yesterday I had the staples removed - it was quick and except for a few bits where the healing skin had caught, painless, and the little bit of pain was just a pinch. So don't worry.
Now I pushed myself yesterday, I went to a meeting with a client at 8am in town. That meant taking the Tube. In peak hour. My worst nightmare. Walked about a mile to get between stations office and home. Then I walked to the doctors - about another mile round trip. By the time I got home, I was knackered and had a little nap.
When I woke up I checked my stationery-less stomach and noticed that two of the keyholes the skin had split from each other again - well, not so much because the skin split, but the surgical glue did. I am now repatched with steri-strips and waterproof patches for another few days (all these years of having a Senior First Aid certificate have come in handy!)
Spoke to my GP, it is totally normal and I don't need to freak out. Just need to take it easy for a few more days.
On the plus side....being on a moving jolting train was like being burped - I let out a ton of gas yesterday!
