I guess I don't mean, it "wrecks" your stomach muscles. They will heal. You'll probably be able to do everything you once did-but healthier and with more energy
BUT
They make your stoma hole by cutting a hole THROUGH your abdominal muscles. No way around it.
And even if it is an
open surgery, they don't cut your abdominal muscles all the way down. (ideally) They cut along a line called the linea alba. It's your midline area BETWEEN your muscles. So it doesn't matter if it's done laproscopically or not. That incision will heal and shouldn't cause any problems. (Laproscopic is less painful though, and less invasive.) The damage is done when they make your stoma. You will always be at risk for a hernia. Because you have a pathway through your muscles.
Now having said that (again), I recently tried to do some crunches. I know my surgeon said not to, but lots of people on here have tried and do fine. So, I thought what the heck! I won't be doing any olympic weight lifting, so it what could it hurt? It seemed ok. So, I'll probably try again.
Talk to your surgeon. He/She will have the most educated information on what you "should" and "shouldn't" do. (I put those in quotes, b/c do we all listen to exactly what our Dr.'s tell us.....probably not
)
