4 Weeks Post Surgery - Eating Question

hi everyone,

I had part of my colon removed 4 weeks ago and a temporary colostomy bag put in. I am on a low residue diet, and slowly introduce new foods back in. I'm mainly eating whole wheat bread, cereal, soy milk, chicken, turkey, fruit, some vegetables and eggs. I still am not eating a regular size portion. I fill up quickly. The most I can eat is a half sandwich at a time and I'm done.

But the problem is, is that every time after I eat, probably 10-15 minutes later when I stand up, I feel really sore in my abdomen when walking around. Other times when I haven't eaten, I don't feel this sore.

Is this normal?

It feels achey and sore. Not necessarily painful. I didn't have laproscopic - I wish! :) I have an incision from my belly button down pretty low :/

I was figuring it was because my stomach was expanding, and pushing on the muscles.

I have an appointment with my surgeon next week and will ask just to be sure.

Thank you!
