Why is flatulence more common among
elderly? Or is it?
You
probably haven’t met an 8-year-old boy who doesn’t fall about laughing when
someone farts. Whoopee cushions have long been the source of belly laughs for
older folk. But there’s no doubt, when
you suffer flatulence in a social situation, it’s embarrassing. And it appears the problem does worsen as you
grow older.
While
flatulence is an important signal of normal bowel activity, and people on
average fart 14 times a day, as we age typically our digestion slows. That gives our intestinal bacteria more time
to produce turn dinner into gases like methane and hydrogen.
So
we have more gas as we get older, and also it doesn’t behave as discreetly as
it did when we were younger.
As
we age gas tends to build up in the lower colon before making a sometimes rapid
and noisy escape, says Karen Hall, MD, PhD, an associate professor of medicine
at the University of Michigan who specializes in geriatrics and
gastroenterology. “There isn’t necessarily more gas,” she says, “but there’s a
higher potential for embarrassment.”
The
noises commonly associated with flatulence are caused by the vibration of the
anal sphincter, and occasionally by the closed buttocks as the gas formed as a
by-product of the digestive process is expelled from the rectum..
Diet
plays a major role in what causes flatulence. Gas-producing foods such as
beans, cabbage, and broccoli are some of the major culprits, but they are
healthful, so don’t cut back on them. Instead try chewing your food slowly and
thoroughly. Chewing food for longer allows the enzymes in saliva to break the
food down before it enters the stomach and digestive tract.
The
more that food is chewed, the more it is broken down for the digestive system.
What’s more, swallowed air is a prime cause of flatulence, and careful chewing
avoids the swallowing of air that occurs when food is eaten too quickly.
Also
try probiotics, gut-friendly bacteria available in supplements and foods like
yogurt, kefir, and tempeh. A 2005 Mayo Clinic study of 48 patients found that
taking probiotics containing acidophilus and bifidobacterium bacteria for 4
weeks decreased flatulence and bloating.
You
can also keep excess air out of your system by going easy on carbonated
beverages. And get regular exercise, which keeps things moving in your
digestive system, giving bacteria in your intestines less time to make gas.
That
way you’ll give those 8- year-olds less cause for mirth.
