Increasing Flatulence
Q: This is really embarrassing. As I've gotten older, I've developed
an increasing problem with passing gas. It happens all the time without warning,
like when I sit down or pick up something heavy. It's getting to the point
where I feel too anxious to go out to a restaurant or party. I've already
tried cutting out problem foods like dairy and beans, but it hasn't helped!
Is there anything else I can try?
Dr. Donnica: Age-related changes in the large intestine, along with increased
use of medications and reduced physical activity, tend to slow the transit of
stool through the large intestine causing an increased incidence of flatulence
(gassiness) as well as constipation. Flatulence occurs when a food does not break
down completely in the stomach and small intestine. As a result, it gets into
the large intestine in an undigested state.
There are certain foods known to produce more flatulence than others, either
because they contain more indigestible carbohydrates than others (beans) or
because the individual lacks the enzymes necessary to digest them. This is the
case with people who have developed lactose intolerance and have trouble digesting
milk and dairy products. If you are lactose intolerant, products such as Lactaid™
would be helpful.
There are several non-prescription products marketed to help reduce flatulence
in general, such as Gas-Ex™ and Beano™. I also recommend that you
try a gas-reducing diet. There are many approaches (visit www.gicare.com/pated/edtgs12.htm
for some examples) but the object of all of them is to identify which particular
foods cause you the most problems with gas and to either eliminate them from
your diet or limit the consumption of that particular kind of food. There are
two general approaches. The first is to continue to eat as you normally do,
but eliminate one category of gas producing foods for at least a week. If there
is no lessening of gas, put those foods back in your diet and then eliminate
another category for a week. Follow this procedure until you reach a level of
flatulence that is tolerable.
Since your situation is so bothersome that it's interfering with your
social life, I recommend the second approach. Severely restrict all categories
of gas producing foods for four days. Then reintroduce one food at a time. If
this addition causes no increased flatulence, continue to enjoy it. If you notice
an increase in gas, eliminate the food item permanently and go on to try the
next food. Continue this process until you've identified all of the foods
that cause gas. The foods that are the worst offenders in flatulence production
vary greatly among individuals, but they generally include: all kinds of beans;
all kinds of milk and dairy products; onions; celery; carrots; raisins; apricots;
prunes; wheat products; and Brussels sprouts.
