Basic causes of chronic constipation in children and adults are similar.
When the constipation continues for more than 3 months, it is considered to be chronic.
The general constipation causes, symptoms
continue to be present for a longer time.
In elders, there may be some added causes due to age. All elders are not likely to suffer from constipation. Their lifestyle, food habits since childhood as well as in adulthood also matter.
Those having healthy food habits since childhood are likely to continue with the healthy lifestyle and they are not likely to suffer from constipation.
Even those who change their not so healthy eating habits as they age, may not be troubled with constipation. And it is never too late to start healthy food habits and healthy lifestyle.
So there is hope for those who suffer from chronic constipation. The results of changes in food habits and healthy lifestyle may take longer to show.
Some medicines that the elders are taking can cause constipation.
Dehydration - some elders avoid drinking water or other fluids as that can make them visit the toilet frequently. They may be reluctant to leave their place because of knee joint pain.
Some elders refuse to change their food habits. They want to continue the similar kind of unhealthy food (low fiber, high fat etc) they have been eating when younger.
The dentures may not be fitting properly and they can not chew the food properly.
They may have some problems of the digestive system, rectum, colon etc.
Having a stroke can cause cronic constipation.
They may get obsessed with not being able to have a daily bowel movement and use (misuse) laxatives too often.
