To answer your questions:
1) Some considerations would be gastroparesis (which would be tested with a gastric emptying study), peptic ulcers, GERD, inflammation of the upper digestive tract and malabsoprtion syndromes (such as celiac disease). I would suggest an upper endoscopy or gastric emptying study to evaluate for these diseases. You can also consider an abdominal ultrasound or HIDA scan with CCK stimulation to evaluate the gallbaldder and evaluate its function.
2) In addition to Levbid, you may want to consider whether Reglan, Phenergan, Compazine, or Bentyl may help your nausea. These medications can be discussed with your personal physician.
Followup with your personal physician is essential.
