I was just diagnosed with hyperkinetic gallbladder, and I have experienced diarhea at times, though better now, and stomach pain, nausea and bloating after eating even a small meal that continues for hours. I was offered surgery to remove the gallbladder, but also told that I could first try to manage it conservatively with referral to a GI doctor. My mom had her gallbladder out at about my age, so I went directly to a general surgeon who ordered an ultrasound (normal) and then the HIDA scan, which revealed the condition. It really destroys quality of life and can eventually lead to additional serious problems in the digestive system if not addressed. I'm still hoping to avoid the surgery, but after searching the internet and reading too much, the likelihood of avoiding surgery is not clear. I may elect to see a Functional medicine doctor first. Good luck to you.
