QUESTION: Now that I have finally put together an exercise program, including some running, that will do all those health promoting things you write about, I now have to deal with a bad stomach after my running.
Is this usual, and what can I do about it? Getting this thing started wasn't easy and I don't want to quit now.
ANSWER: Stomach problems and other gastrointestinal distress are pretty common in runners and other athletes.
One study has shown that 12 percent of runners experience belching or heartburn and another 37 percent feel a severe need to move their bowels while running.
It's been found that women runners are more likely to have lower intestinal discomfort than men runners.
There is some evidence that up to 30 percent of runners show blood in their stool, but no one is certain what is causing this.
On the up side, two large studies have shown that exercise decreases the risk of colon cancer. Many of these problems may be due to the intestinal motion that running causes.
Runners have more frequent bowel movements and food passes through their intestinal system slightly more quickly.
However, runners also usually eat a diet higher in fiber, which also speeds up the intestinal system. There are several things you can do to relieve your own distress.
To reduce nausea, cramping and vomiting, don't eat for three or four hours before you run.
This way your stomach will be empty while you exercise.
If you suffer from diarrhea during long training runs or races, try eating a low-residue, low-fiber diet for one or two days before the event.
You might also try emptying your bowel before competition by drinking coffee or tea or by having a light workout.
If these steps don't work, see your physician to rule out other problems, such as lactose intolerance.
