Indicate the causes and effects of constipation
What will be an ideal response?
Constipation occurs when feces remain in the colon for longer than normal periods, which causes more H2O to be absorbed, making the feces hard and dry. Factors that could lead to constipation include: (1) ignoring the urge to defecate; (2) decreased colon motility resulting from aging, emotion, or a low-fiber diet; (3) obstruction of fecal movement caused by a local tumor or spasm; and (4) impairment of the defecation reflex, such as through injury of the nerve pathways involved. In some cases, constipation can allow hardened fecal material to become lodged in the appendix, causing it to become inflamed (appendicitis). This can lead to circulatory interference and if the appendix ruptures, the result is the spread of bacteria into the abdominal cavity.
