I'd say there's lots of variables depending on your Dr's, your health, etc. I'm 44yrs but when I was 21yr I had an emergency total colectomy (removal of LG intestine)in OC, CA, USA dropped to 113lbs from 180lbs. I had complications due to negligence they ordered a CT scan with barium sulfate (they should've used gastro-graffin?) So it leaked through my ulcer perforations causing another 10+ surgeries over a 3.5yr period at Stanford hospital, CA (most surgeries were emergency as the J-pouch leaked causing me to go septic, patched it & repeated that 2x more, then it burst. my midline incision split open in 2 spots while I still had staples in me so after 2yrs of packing guaze, saline, etc my ins FINNALY paid for plastic surgery oh & nearly every single surgery in 4 different hospitals the Dr's said I'd die & yet here I am.
i Tried the j-pouch but it was either poorly made or my body rejected it, or? But it was miserable while I had it but again I don't think I was your normal case, whatever normal is but I really wanted it to work, as I did struggle with depression, from the stoma, however I learned to change my perspective & count my blessings & tried to enjoy life to the full. I never hit the gym but during CV-19 I got a perastoma hernia from sit ups but again everyone's different & we all have our struggles but do your research so you're not going in blind expecting the Dr's to do everything perfectly. Ppl make mistakes & everyones disease varies in severity but if your young & healthy, Dr's are experienced & your willing to weigh the risks that's all u can do. Much success to u 🙏
