stomach pain after surgery

I had my surgery 5 years ago and i lost about 150 pounds but I also have been having stomach pains during meal times ever since.. I have told my doctor and they did the scopes but they say nothing is wrong... I was wondering i saw a article about the opening from the throat and the stomach being to small and that can cause the pain i have.. Has anyone else heard of this?  I have a hard time eating protein, but the soft junk goes down fine so alot of the time i pick those because i am tired of the pain..... any advice or comments are welcome..

Having pain every time after eating is not normal. 

But ..I do have pain after eating when I eat too fast, I don't chew enough..or simply eat too much for that meal or that day. I have large pouch days and small pouch days. 

On a small pouch day I can eat about 1/2 of what I can eat on a large pouch days. 

And there is also different type of pain. If I eat food I have allergy or intolerance to - my pouch hurts. 

If the food is too cold - it hurts. If it is too hot... It hurts..  Just because I really like drinking hot tea or coffee - it does not mean my pouch does. 

There was also different pain AFTER I ate when I had hernia, or just twisted intestine, or even pain due to gas, constipation or IBS.  Or gallbladder- liver pain... 

You need to write down what type of pain you have, when do you have it... How long it lasts..etc... And you need to find a good doc - baritric surgery doc or a very good gastro who can help you figure out why you are hurting.... 

Post op RNY I got SIBO that is causing IBS-C... Now if I eat food that agrevates the condition - I pay for it. 

Google SIBO..if you need to know more. Having RNY makes us prone to have that. And Candida.
