Those sound like the symptoms I had with my gallstones. I vomited every morning for 6 months as my main symptom for a long time. I lost a lot of weight. After I got diagnosed I had to wait a week for surgery. At work we had a party, which unfortunately had pizza and the highest fat food on the planet - cheese cake. I had veggie pizza and two bites of cheesecake to be polite (I had no appetite and never ate cheesecake EVER), and that's when I had my first gallstone attack. It lasted 36 hours, and I had severe BACK pain which I think was on the left, and that's not even the correct side. Didn't matter if the pain was "right," some people's pain is atypical and I already knew it was gallstones.
Hi, an ultrasonography can help pick up gallstones. In the meantime avoid all food high in fat and cholesterol. Also avoid all food high in calories and include plenty of high fiber diet. Avoid all fried food, fatty red meat, whole milk dairy products and highly processed food. Include plenty of fresh fruits, high fiber vegetables, whole grains, lean meat and low fat dairy products. This could reduce your symptoms of pain and gallstone formation. Regards.
