Is it possible to stretch my stomach after a sleeve gastrectomy surgery? How long would it take?

Hi. Its looks that you sleeve is good. Remember that the stomach will spand if you every time try to eat all that you can even if you feel pain. Try to control portions and choose hight quality food. The most important issue is that you must change eating habbits and workout hard at the gym. If you eat the same way like before surgery then even the best surgery with the time will lost. I think that you can do it and is too soon to consider a new surgery.regards

The stomach walls are muscle, and they contract and expand as we eat, so the stretch a bit. Immediately after the surgery, the scaring process and swelling might make your new stomach a bit rigid, so as the healing process continue it will expand a little bit when you eat. That’s why we tell the patient that the portion that you eat approximately 8 months after the surgery it is the potion that you will end up eating for then on.

The healing process of the sleeve gastrectomy makes the stomach  rigid  in the first  6 months after the surgery because of the  scarring  in the staple line ( in other words; it does not allow a lot of distension), between  the 6 to 10 month  period after surgery the stomach regains elasticity, this is why at this time  you can eat more food compared to a couple of months before,  the capacity will increase  a little more, in most patients the capacity of the stomach becomes stable (it won't stretch more) at 12 to 18 months  after surgery  staying at around ⅓ to a half   of the previous capacity to solid food.  
Avoid the habit  of eating until you feel pain , stop when you feel full or satisfied.
