Can an anatomical abnormality in the large intestine cause a delay in transit of food , and can this delay over time cause kidney disease?

If you have not yet had your colonoscopy, get it right away. Good luck. ...Read more

Can biliary reflux from the small intestine into the stomach cause slightly elevated liver enzymes?

No, get checked: Your transaminitis (elevated liver enzymes) indicates, albeit non-specifically, a sick liver.
