It is likely impaction if it is a boar, or bloat. This is serious. Take your pig to an exotics vet for an exam. You'll likely have to change the diet (they should be getting mostly hay, a small amount of timothy-based pellets and about 1 cup veg - leaf/romaine lettuce, endive, some parsley, bell peppers, the occasional blueberry/tomato/carrot/apple/orange slice).
