How long you should wait to see a doctor for GI symptoms?

When’s the last time you really stopped to think about your poop habits? It’s not usually top of mind for most people. But that, along with addressing other persistent gastrointestinal issues, can be the difference between catching a dangerous condition early – or too late. It can also mean putting a stop to unnecessary suffering for a treatable symptom.

The American Gastroenterological Association released a survey in 2022 that found 40% of Americans suffer from daily digestive trouble. Some also seem to be just dealing with it, including one in three who would only bring up symptoms if their doctor asked first.

Meanwhile, GI cancers from the esophagus down through the rectum are on the rise, according to the Dana Farber Cancer Institute, especially in young people.

Doctors want patients to take their GI symptoms seriously. “It’s common that patients will have symptoms for a prolonged period or try to treat themselves (pain meds, modifying diet, etc.) before seeking medical attention,” says Dr. Shanel Bhagwandin, medical director of the Gastrointestinal Surgical Oncology Program at Jupiter Medical Center in Jupiter, Florida. “Although most GI symptoms are nonspecific, any persistent or unexplained complaint should prompt imaging, blood work and/or additional diagnostic testing.”

Here’s how to know when to call a doctor.

How long is too long?

Anyone can have an upset stomach or a belly bug for a few days without the need for alarm. But Bhagwandin says if a symptom has lasted two to three weeks, or is worsening, that’s a reason to call your doctor. “Some of the common cancers I see and treat, including colorectal and pancreatic cancers, will often begin with subtle, easily dismissed symptoms,” he says.

You can start with your primary care provider (PCP), or schedule directly with a gastroenterologist. Patients worried about finding something wrong can rest assured that there is often a less complicated explanation for GI symptoms, such as constipation, that's very treatable.

What symptoms should you pay attention to?

Nobody wants to talk about poop or other GI problems, but Bhagwandin says, “It’s important to bring ‘toilet talk’ to the dinner table – not literally, but culturally. We need to normalize conversations about bowel habits, bleeding and changes that affect our GI system the same way we talk about blood pressure or cholesterol. When we remove the stigma, we give people permission to seek care earlier, when it matters most.”

“The more notable red flags include blood in the stool, unexplained weight loss, ongoing abdominal pain, difficulty swallowing, persistent nausea or vomiting or changes in bowel habits – like new-onset constipation or diarrhea that doesn’t resolve,” he adds.

“Chest pain and shortness of breath can also indicate GI issues, but you should speak to your PCP to ensure your heart and lungs are OK before considering a GI diagnosis,” adds Dr. Pratima Dibba, a board-certified gastroenterologist with Medical Offices of Manhattan in New York. 

How can I prevent serious GI conditions?

Cleveland Clinic recommends eating a nutritious diet, exercising several days per week and going to the bathroom right when you have to, to help prevent GI conditions. You can also consider the role of gut health in digestion.

“Screening – particularly for colorectal cancer – remains one of the most powerful tools we have in medicine. When it comes to artificial intelligence and identifying the single-most impactful screening test to prevent cancer after age 45, it’s not a full-body scan or a cutting-edge blood test, or something futuristic – it’s a colonoscopy,” Bhagwandin says. 

He also wants people to know they are their most important advocate, and should listen to their instincts about GI symptoms. “Patients often sense when something isn’t right, even before tests confirm it.”
