Brief answer.....A very common problem in the elderly above 65 years age.
Detailed answer...
Hello,
Thanks for the query.
Constipation and resultant gas feeling is a very common problem above the age of 65 years because intestines tend to become sluggish with age,however it should not be ignored because constipation could be the sign of a serious problem such as a mass lesion or the manifestation of a systemic disorder such as hypothyroidism or a side effect of medications such as narcotic analgesics,diuretics,antacids,pain killers,calcium channel blockers,iron supplements  etc.
As for where the problem originates, your colon is generally the culprit, since that's where the fluid is removed from the stool in the bowel.
If you are eating less or drinking less fluids and are sedentary,then these would result in constipation.
Treatment involves ...
Avoiding laxatives or stool softeners as they cause more rebound constipation.
Take more of Fiber in diet.
Do regular exercises.
Take plenty of water.
Take ISABGol husk 15 gms daily with one glass of water.
This should solve the problem but you must first consult  a doctor and try to rule out diseases like mass lesions of colon,hemorrhoids,hypothyroidism etc.
I hope it helps,however you may revert to me for any further problem.
Best of luck
Thanks
