However, ever since my surgery I've been having lots of intestinal problems. Almost like mega IBS flare-ups. I knew I would need to stay on a very low-fat diet after my surgery, but I've practically needed to be on a no fat diet since even small amounts of fat seems to cause me problems. And if I ignore my body's warning signs of too much fat intake (gas, gloating, intestinal cramping, and increasing heartburn), the consequences are not pleasant. I become constipated and then I start throwing up. I do this until I seem to be "cleaned out" and then I'm fine. The first time this happened, I thought I had a bad case of the stomach flu. The second time it happened, I thought the same thing, but thought that something else may be going on. The third time it happened, I really thought about what happened to me in the days before the "flu" hit me this time. I knew I had ignored the pain and gloating from eating to much fat in the couple of weeks before this (and the other times) and when I got to the spot when my digestive tract felt like it was "stuffed" like food is just stuck, and when it felt like a rock was in my stomach, I began vomiting. Once I felt empty, the vomiting stopped and the constipation was gone. I swear it's like my digestive tract is rebelling and shutting down briefly and I vomit because it's the only way my stomach has to get rid of the food that won't digest. After a couple of days of that, I recover slowly and can eat and everything seems to work fine.
