Everyone feels bloated at times after eating. Bloating is a feeling of tightness, fullness, or pressure in the belly that comes along with abdominal swelling and mild to intense pain. Excessive gas buildup from a sluggish digestive system and problems digesting certain foods are the leading causes. While most bloating goes away after a while, for regular occurrences, people should examine their diet for trigger foods and use over-the-counter anti-gas remedies as needed. In cases of frequent or extended bloating, a doctor should see if other problems are present.

There is a lot of anecdotal information about people using apple cider vinegar to treat heartburn, but no published research examining the validity of it.

There are several at-home screening tests for colorectal cancer. The most accurate are a fecal immunochemical test (FIT) and a multitarget stool DNA (mt-sDNA) test (Cologuard), also known as a FIT-DNA test. The FIT test uses antibodies to detect blood in stool, and must be done once a year. The FIT-DNA test can identify DNA from cancer cells in the stool and also has a FIT component to look for blood. This test may be repeated once every three years.

Emotional stress can aggravate gastroesophageal reflux disease (GERD), a condition in which gastric acid washes backward into the esophagus from the stomach. Managing stress through meditation or exercise can help.

Gut bacteria may influence our emotions and cognitive capabilities. For example, some bacteria make oxytocin, a hormone the body produces that encourages increased social behavior. Other bacteria make substances that cause symptoms of depression and anxiety. Still others make substances that help people to be calmer under stress. Gut bacteria also have been shown to influence people's vulnerability to certain brain diseases, including Alzheimer's disease, Parkinson's disease, and autism. For example, a substance found in the brains of people with Parkinson's disease (synuclein) is made by gut bacteria and can travel via nerves from the gut to the brain.

Many conditions of the gastrointestinal tract are easy to diagnose using standard testing. But some such diseases can impact the GI tract without a clear test finding. Disorders of gut-brain interaction are so called because they involve impaired communication between the gut and brain via the nervous system.

Heartburn and gastroesophageal reflux disease are two of the most common digestive-related problems, but they often get confused with each other because they share many of the same traits. While the two conditions are connected, they are quite different. Recognizing the difference can help a person adopt lifestyle changes to manage symptoms and know when to seek other options, like medication and surgery.
