Hello! Thank you for the query. Your symptoms can be caused by an infection of gastrointestinal tract. However it can be also a symptom of stomach disease (like peptic ulcers, inflammation), stones in the bile ducts, pancreas disease. With stomach disease you should have upper middle abdominal pain after a meal, acid reflux can be present. Bile ducts problem should cause upper right abdominal pain, radiating to the back. Urine can get darker. Pancreas disease gives similar to bile ducts symptoms. I suggest you to visit your doctor and have some basic tests. Abdominal ultrasound, blood work, liver tests, urine analysis should be done. You should also get scheduled for gastroscopy. In a meanwhile avoid fatty foods, spicy foods, alcohol, coffee, chocolate. Hope this will help. Regards.
