While there's no cure, people can manage celiac disease by adopting a gluten-free diet. Within several weeks, inflammation in the small intestine will subside—though accidently eating a product with gluten could cause a flare-up at any time.
The fact that Americans spend $725 million a year on laxatives suggests that trying to unclog the nation's plumbing, so to speak, is almost a national pastime. But overuse of stimulant laxatives, which cause the intestines to contract rhythmically, can make the gut dependent, requiring more of the drug and eventually rendering the aid ineffective.
First, a bit of clarification on the, um, frequency of your flushing: There's no need to obsess about having a daily bowel movement; anywhere between three times a day and three times a week is normal, says Sandler.
But if you're experiencing discomfort and can't make your bowels move, try an over-the-counter remedy like good old milk of magnesia, he says. And whether you've tried laxatives or not, going a week without a bowel movement is good reason to visit the doc, says Sandler. Constipation, hard stools, and straining could lead to hemorrhoids or an anal fissure.
Constipation is best avoided through regular exercise and a diet high in fiber from whole grains, fruits, and vegetables. To older folks, who tend to get constipated more frequently: Be sure you're hydrating properly and aware of any medications that might be causing the holdup.
