Digestive troubles? Don’t suffer! Here are some smart solutions.

By Consumer Reports

Just about everyone experiences digestive problems on occasion. They’re some of the most common complaints in doctors’ offices. But for more than 10 million people, gas, bloating, constipation, diarrhea or heartburn are a regular occurrence.

When your doctor can’t find an underlying reason for the problem, it’s dubbed a “functional” gastrointestinal disorder, meaning there’s no specific cause, which makes it even more frustrating to deal with.

In many cases, though, there’s a way to get some relief. “There can be many causes of these problems, but often, if we can’t point to one thing, altering the diet might help,” says Robert Hirten, an assistant professor of medicine and gastroenterology at the Icahn School of Medicine at Mount Sinai in New York.

Although chronic digestive disruptions warrant a doctor’s attention, “generally about 80 percent of patients will benefit from doing some sort of diet intervention,” says Melissa Phillips, a clinical nutritionist at the University of Wisconsin Health System’s Digestive Health Center.

Here are eating strategies that can help keep your gastrointestinal tract in good working order.

The Mediterranean-type diet nourishes your gut microbiome.

Go Mediterranean

Your digestive system is teeming with healthy bacteria (think probiotics) and other microorganisms that aid in digestion, bolster your immunity and provide overall health benefits.

A Mediterranean-style diet ­— rich in fruits, vegetables, whole grains, legumes, olive oil and nuts, with some fish, dairy and lean meat — supplies fiber to feed beneficial bacteria. And olive oil contains antioxidant polyphenols that may help control inflammation.

A Mediterranean-style diet is also low in added sugars and processed foods, two factors that are important for a healthy gut, Hirten says.

Increase your fiber

Even if you don’t switch to a Mediterranean diet, you should get plenty of fiber-rich foods — fruits, vegetables, whole grains and legumes. Eating 25 to 30 grams of fiber a day can help normalize diarrhea and constipation, Hirten says.

There are two forms of fiber. Soluble fiber helps lower cholesterol and possibly blood sugar; sources include apples, oats and legumes. Insoluble fiber helps bulk up stool and promotes the contractions in the intestines that propel it through your system; sources include whole wheat, popcorn and green vegetables.

“If you’re constipated, add more insoluble fiber,” Phillips says. “If you have diarrhea, opt for more soluble fiber.” But incorporate fiber gradually into your diet. If you try to do it all at once, you might exacerbate your symptoms.

Drink enough water

Fiber absorbs water, making stools softer and easier to pass. If you’re dehydrated, fiber will be less effective and may cause more digestive symptoms.

There’s no set guide­line for how much fluid to drink, but eight cups a day is a safe goal for most people. Water, sparkling water, milk, juice and noncaffeinated beverages count toward your daily intake amount, Phillips says, but water is the best. Sparkling water, milk and juice can sometimes trigger bloating.

Add natural probiotics

Yogurt and other fermented foods such as sauerkraut, kefir and miso may help populate your gut with healthy bacteria. There are no guidelines for how often to eat probiotic foods, but trying to incorporate them as part of an overall healthy diet could help.

Supplements that contain “live cultures” and strains of bacteria haven’t been shown to benefit digestion. “I rarely recommend people start taking probiotic supplements, simply because we just don’t have enough evidence to suggest it helps or hurts,” says Meagan Bridges, a clinical dietitian and nutrition support specialist at the Uni­versity of Virginia Health System.

Eat on a schedule

Your digestive system prefers a routine. “It likes to know when you’re going to be eating and how much, so it knows when to work and when to rest,” Bridges says. “I tell my patients to try to eat at about the same time each day and the same amount of food.” Constant grazing or an erratic schedule can result in constipation.

In addition, avoid eating right before bed, which can lead to heartburn or indigestion. “Digestion slows down at night, and it takes longer for food to be absorbed,” Bridges says.

Slow down at meals

Digestion begins in the mouth, so thorough chewing sets the stage for the rest of the process. In addition, eating quickly or gulping down your food can make it easy to swallow air and lead to belching.

Eating too quickly is bad for your digestive health.

Check your supplements

Iron can cause constipation and magnesium can lead to diarrhea, Phillips says. In addition, some supplements as well as over-the-counter and prescription drugs can contain sorbitol or mannitol, sugar alcohols that may have a laxative effect or cause gas and bloating.

An eating plan for tummy troubles

For some people, even healthy foods — such as cauliflower, cashews, lentils, onions, peaches and wheat — can cause gas, bloating and discomfort. That’s because foods like these contain hard-to-digest carbohydrates called fermentable oligo-, di-, monosaccharides and polyols. (FODMAPs). A 2016 study published in Clinical and Experimental Gas­tro­enterology found that a low-FODMAP diet may help irritable bowel syndrome and may be particularly beneficial for people who have abdominal pain along with constipation or diarrhea.

Following a low-FODMAP diet, which involves eliminating these foods for two to six weeks, then slowly adding them back in small amounts, may help but should be done in consultation with a dietitian, Phillips says. “It’s meant to be a learning diet, not a permanent one.”

But before you start cutting out things, Hirten recommends tracking what you eat and drink and your symptoms for a week. “It can give your doctor clues about potential triggers and make the connection between foods and symptoms much clearer for the patient, too,” he says.

Is it time to call the doctor?

Occasional digestive upset is normal, but anytime you have symptoms that won’t go away, check with your doctors. And alert them immediately if you notice the following:

• Bloody stools.
• Severe abdominal pain.
• Tender or swollen abdomen.
• Persistent nausea or ­vomiting.
• Fever.
• Diarrhea that lasts more than two days.
