Are Thin Stools Indicative Of An Underlying Medical Condition?

Had an appendectomy a year ago. My appendix ruptured and spent 5 days in hospital. 3 months after i developed an abcess and was placed in hospital with drain tube for 5 days with iv antibiotics. Shortly after recovery I experienced extreme constipation, so bad it required gloves and some digging out because enemas was not working alone. Now my stool over 1 yr later is thin. The stool appears more elongated than bulky. My constipation has subsided with more fiber intake but my concern is the narrowing is that normal?
