[|Human|] Hi. I m a 50yr old healthy male and I have suffered with upper central abdominal pain for about 7 months nows that radiates to my back at times. The pain is constant, but is made worse when I don t eat and when I do. When I eat I feel full very quickly, my stomach bloats, and becomes really tight. I find it difficult to swallow when I eat. After eating I produce a lot of gas and feel nauseous. I go to the toilet and defecate numerous times a day and what comes out is soft, greasy and floats. My urine is a lot darker and I ve noticed my the whites of my eyes are yellow. I ve been to the GP a number of times but they haven t been much help, they give me medication which makes me worse and they don t know what is wrong. I ve been tested for the food intolerances but I have none, had an endoscopy which showed my oesophagus and stomach are fine and had an ultrasound which shows no gallstones. I ve lost a bit of weight but I m not sure as to whether this because I can t eat as much? Any ideas on what it might be or what I should do?
[|AI|]  Dear Nicky, The duration of the pain that you mention is of concern. Even though you have had normal endoscopy and normal ultrasound, the symptoms do suggest that you do have some upper intestinal problems. The mention of greasy foamy stool suggests that you have problem digesting fat. This might happen when your pancreas is not functioning properly. Repeated attacks of inflammation of the pancreas can cause this type of damage and the condition is called "Pancreatitis ". Even though the most common cause is gallstones, other conditions can also cause this. This could be alcohol related or viral infections. I would recommend that you see a digestive disease specialist who can perform aditionaltesting to look for problems with pancreas. Good luck,
