Fiber-Rich Foods and Simple Diet Changes Can Help Relieve Constipation, Experts Say

Health experts say constipation can often be managed through simple dietary changes, with fiber-rich foods, adequate hydration and healthy lifestyle habits playing a key role in improving digestion before medication becomes necessary.

Constipation is generally defined as having fewer than three bowel movements a week, often accompanied by hard, dry stools that are difficult to pass. While occasional constipation is common, doctors say persistent symptoms should not be ignored.

One of the most effective ways to improve bowel health is to increase daily fiber intake. Adults are advised to consume between 25 and 34 grams of fiber each day, although many people fall short of that target.

Dr. Trisha Pasricha, a physician-scientist at Beth Israel Deaconess Medical Center and assistant professor at Harvard Medical School, said vegetables are among the easiest ways to increase fiber intake. She recommends peas, which provide about 9.4 grams of fiber per cup, along with Brussels sprouts and artichoke hearts, which are also rich sources of dietary fiber.

According to gastroenterologist Dr. Nicé Bertha Toriz, fiber works by increasing both the weight and water content of stool, making it softer and easier to pass while helping it move more quickly through the colon.

Beans and lentils are also among the top foods recommended for digestive health. Black beans, pinto beans, lentils, chickpeas and edamame all provide significant amounts of fiber while also serving as nutritious plant-based protein sources.

Fruit can also make a difference. Studies have shown that eating two kiwis a day may improve bowel movement frequency in people with constipation, producing results comparable to some fiber supplements. Researchers believe the fruit’s benefits may extend beyond its fiber content, although the exact reason remains under investigation.

Dried plums, commonly known as prunes, continue to be one of the most widely studied natural remedies for constipation. Research suggests eating several prunes daily can improve stool consistency and increase bowel movement frequency. Experts note, however, that prunes may cause bloating in some people.

Doctors recommend increasing fiber intake gradually rather than all at once, as a sudden increase can lead to gas, bloating and abdominal discomfort. Adding about five grams of fiber each week allows the digestive system to adjust more comfortably.

Warm beverages may also provide relief. Coffee is known to stimulate bowel activity in many people, while warm water and decaffeinated coffee may also encourage movement in the digestive tract, though generally to a lesser extent.

If dietary adjustments fail to improve symptoms, medical advice should be sought. Healthcare providers can recommend appropriate laxatives or investigate whether an underlying digestive disorder is responsible. They may also suggest lifestyle measures such as improving sleep, reducing stress or pelvic floor therapy.

Doctors advise seeking prompt medical attention if constipation is accompanied by warning signs including blood in the stool, black stools, unexplained weight loss or persistent abdominal pain, as these symptoms may require further investigation, including a colonoscopy, to rule out more serious conditions.
