Answer:
Constipation is a condition (not a disease) where a person passes small amounts of hard, dry stool, usually fewer than three times a week. The person may also have a feeling of incomplete elimination of stool. Other symptoms are feeling bloated and sluggish.
The usual causes of constipation are: not enough fiber in the diet, lack of physical activity (especially in the elderly), medications, changes in life or routine such as travel, overuse of laxatives, ignoring the urge to have a bowel movement, and dehydration. Adding in the factor of aging, which includes hormonal changes, an aging liver, slower gut activity, stress, and worrying over menopause, can further contribute to the complicated condition of constipation.
Make sure that you take care of the common culprits first. In addition to high fiber diet (fruits, vegetable, whole grains), physical activity, and adequate fluid intake that you are currently doing, it is also important to avoid overeating and eating processed/fast/"junk" foods. If you are still suffering from constipation, then it is time to look into the less common causes. You need to consult with your doctor regarding side effects of your medicines, as well as potentially serious medical conditions.
