What kind of hernia or condition...Can cause distended stomach, balls lower than usual?

Inguinal hernia. Depending on where your stomach is distended, it sounds as if you may have an inguinal (groin) hernia -- a weakness in the abdominal wall muscles that can allow the guts to push out with upright position, coughing, lifting, or straining. Since an inguinal hernia is closely associated with the cord that goes to the testicle, it can push the testicle lower in the scrotum or enlarge the scrotum.
