Lingering gas and bloating can be set off by a recent long-haul flight.But similar symptoms could also represent something far more serious. It can be tricky to tell with the gastrointestinal tract, the long tube that runs from the mouth to the end of the large intestine. We asked gut health experts to share some of the warning signs they\u2019d never want their patients to ignore.1. Blood in the toilet.When people see blood in or on their stool, they often ignore it because they assume it\u2019s from hemorrhoids, said Dr. Cathy Eng, a professor of medicine at the Vanderbilt-Ingram Cancer Center.When hemorrhoids, which are swollen, inflamed veins, are irritated or pressure is applied, they can cause bright red blood to appear on toilet paper, or as drops in the toilet bowl or on the surface of your stool. But it\u2019s often not possible to tell by appearance whether the blood is from hemorrhoids or something more serious, Dr. Eng said.AdvertisementSKIP ADVERTISEMENTHealth issues like colorectal cancer, Crohn\u2019s disease, diverticulitis and even certain stomach bugs can also cause blood to appear in or on the stool, said Dr. Baha Moshiree, a gastroenterologist and professor of medicine at Wake Forest University School of Medicine in North Carolina.Stool that appears black, tarry or dark maroon can be a sign of bleeding in the stomach or upper digestive tract from a stomach ulcer, a cancer in the stomach or esophagus or other conditions, Dr. Moshiree said.Any blood in or around the stool is worth mentioning to a doctor, Dr. Eng said.2. An unusual change in bowel movements.It\u2019s a good idea to tell a doctor about unexpected changes to the shape, frequency or consistency of your bowel movements, like newly appearing constipation, diarrhea or thin stools, said Dr. Andrew Chan, a gastroenterologist at Mass General Brigham in Boston.When such changes occur without a clear reason, like shifts in your diet, medications, stress levels or work schedule, it could signal that something is off, Dr. Chan said. A growing tumor in the colon, for instance, can cause constipation or thin stools, Dr. Eng said. And intestinal inflammation can cause both constipation and diarrhea, often with pain, gas and bloating.3. Diarrhea that won\u2019t go away.If your bowel movements have been loose or watery for more than five to seven days, especially if you also have abdominal pain, cramping or changes to your appetite, it\u2019s worth looping in a health professional, Dr. Eng said.AdvertisementSKIP ADVERTISEMENTIntestinal infections caused by certain pathogens, like the parasites cyclospora or giardia or the bacterium Clostridioides difficile, can cause diarrhea, cramping, pain or appetite changes that may benefit from antibiotics or other treatments, Dr. Moshiree said.Inflammatory bowel diseases like Crohn\u2019s or ulcerative colitis can also cause chronic diarrhea, pain, cramping, gas and bloating, as can celiac disease, an autoimmune condition in which eating gluten causes the immune system to attack the colon. In some cases, colorectal cancer can also cause persistent diarrhea, Dr. Eng said.4. Difficulty swallowing.Any recurring pain, discomfort or trouble with swallowing can be worrisome, Dr. Moshiree said. This includes feeling like you can\u2019t move food from your mouth to your throat or a sensation that food is getting stuck in your throat.If you\u2019re noticing any of these symptoms frequently \u2014 even if they only last for a moment \u2014 see a doctor, Dr. Moshiree said. Nerve or muscle conditions, like Parkinson\u2019s disease or multiple sclerosis, can cause discomfort or trouble swallowing, she said. And conditions that cause a blockage near the throat, such as throat or esophageal cancers, can make it difficult for food to pass through.In severe cases, food that becomes stuck can lead to choking, but \u201cit doesn\u2019t have to be that extreme\u201d to be worth mentioning to a doctor, Dr. Chan said.AdvertisementSKIP ADVERTISEMENT5. Symptoms that wake you in the middle of the night.Diarrhea, abdominal pain, cramping, nausea or other gut symptoms that wake you up should raise an alarm, Dr. Moshiree said. Serious conditions like Crohn\u2019s disease or colorectal cancer can cause these unpleasant nighttime awakenings. Stomach viruses or food poisoning can also jolt you awake, she said. Less urgent gut conditions, like irritable bowel syndrome or run-of-the-mill indigestion, are less likely to disrupt your sleep, Dr. Moshiree said, since their symptoms are more likely to occur when you\u2019re awake.Also be sure to tell a doctor if you\u2019re frequently having night sweats that aren\u2019t menopause-related, Dr. Eng said. Night sweats can be a symptom of many types of cancer, including those related to the gastrointestinal tract, such as colorectal cancer and pancreatic cancers.As a general rule, an unexplained loss of more than 10 percent of your body weight, across any time frame, is worth telling a doctor about, Dr. Moshiree said. Worrisome conditions that can cause unexpected weight loss include gastrointestinal cancers, inflammatory bowel diseases, intestinal blockages and gastroparesis, a disorder that causes your stomach to empty too slowly.The Bottom LineIf you\u2019re unsure whether a digestive symptom is worrisome, especially if it doesn\u2019t resolve within a few days to a few weeks, it\u2019s a good idea to run it by a doctor, the experts said.A primary care doctor at a local clinic, or even a gynecologist, can be a good first stop, Dr. Eng said. That doctor can then refer you to a specialist, like a gastroenterologist, if you need one.AdvertisementSKIP ADVERTISEMENT",
