Those symptoms are not inconsistent with a GB, although most people present with worse problems before they'll take it out (especially without a positive test result). Worse problems including diarrhea (although sometimes constipation), vomiting, extreme nausea, a sense of being stuffed, even though you have barely eaten, indigestion or heartburn, pain in the right arm, severe cramping (some have likened it to labor pains), distinct pain or a lumpy feeling under the right ribcage.
Mind you, if your GB is bad, over time, you will get worse and have most or all of those lovely symptoms. I'm also of the thought--although I haven't any proof--that the longer you live with a bad gall bladder, the less likely you are to recover well after it. Some people seem to be perfectly normal after having it removed, although they seem to be mostly people who got theirs taken out very soon after developing symptoms. Then there are people like me, who have one bad for years, and who are never normal afterwards.
You do need to know that you may not be 100% normal ever again after having it removed. There are certain foods that I can't eat because of it (caffeine being #1), and I have to take medicine to keep from having diarrhea all the time. My MIL and a great aunt also have to take medicine to keep from having D all the time. A few people (10%?) have constipation all the time. And then some, like my mother, develop heartburn as a result. Even if you appear normal afterwards, you may still have a random period of sickness. A lady I worked with said about once a year she had a phantom gall bladder attack that laid her up in bed for a couple of days. But other than that, she was fine all the rest of the time; no dietary restrictions, no gut problems.
