Hemorrhoids affect many people, and by the age of 50, more than half of American adults have experienced issues dealing with them at some point in their life. Even with its prevalence, most people avoid the topic and don’t discuss the condition.

To raise awareness, Rahul Narang, MD, a colorectal surgeon at NYU Langone Colon and Rectal Surgery and clinical assistant professor of surgery at NYU Grossman School of Medicine, speaks with The New York Times about common causes of hemorrhoids and the best course of treatment.

First and foremost, everyone is born with hemorrhoids, which serve an important role in normal bowel function. Only when they become inflamed and enlarged do they present a problem. “Hemorrhoids get inflamed typically because of straining during bowel movements, which puts pressure on them,” says Dr. Narang. To avoid developing hemorrhoids, eat a diet high in fiber, drink lots of water, and don’t spend too much time on the toilet. “Staying hydrated can make a big difference too.” Dr. Narang says. “The fiber and water make it easier to pass bowel movements, which then reduces the chances hemorrhoids will become inflamed.”

If symptoms from hemorrhoids persist, there are simple, at-home treatments available to offer some relief. When symptoms do not improve, Dr. Narang encourages people to seek out a colorectal surgeon for care. Based on the grade of your hemorrhoid, surgeons can offer a variety of nonsurgical and surgical procedures to remove hemorrhoids.
