For about 2 months I've had nausea on and off with achy pain in my lower stomach, very low energy, increased gas. Ultrasound on gallbladder came back normal. Hida Scan said "gallbladder ejection fraction using 17.5 mcg Kinevac is decreased, 16%". "decreased gallbladder ejection fraction which could represent gallbladder dyskinesia in the appropriate clinical setting". Does anyone know what this means? Dr says it not an emergency right now but that I could feel better with surgery.
