Chronic heartburn is sometimes characterized by symptoms that are similar to those of other conditions. This can cause heartburn to go undiagnosed. Examples of nonspecific heartburn symptoms include chest pain or pressure that mimics a heart attack; a dry cough, sore throat, or hoarse voice that seems like it's related to a cold; or mouth sores, ulcers, erosion or wear on the teeth, or cavities. When any of these symptoms occurs regularly, heartburn should be considered as a potential cause.

A healthy diet is key to a healthy gut microbiome, which helps the immune system function well and reduces chronic inflammation among other important tasks. And increasing evidence suggests that fiber and fermented foods can play important roles in gut health.

Proton-pump inhibitors are the strongest type of medicine available for treating stomach acid. There is some concern about their potential side effects and interactions with other medications.

Food-borne illnesses are common, sickening 48 million Americans each year, hospitalizing 128,000, and killing 3,000. One way to keep food safe is to clean the refrigerator and pantry regularly to cleanse surfaces and purge dated and possibly contaminated products. The process should include taking all items out of food storage areas, washing all surfaces, checking expiration dates, assessing products' smell and appearance, marking dates packages are opened, and avoiding cross-contamination between raw and ready-made foods.

A 2023 study suggests that taking low doses of amitriptyline, a tricyclic antidepressant also used to treat nerve pain, may be one of the best pharmacologic choices to help improve symptoms of irritable bowel syndrome.

A 2023 study of lab animals suggests that the population of microbes in an individual's gut may influence the risk of developing Alzheimer's disease. Researchers found that healthy lab rats developed signs characteristic of Alzheimer's disease when they were injected with gut microbe samples from people with Alzheimer's. Rats that received samples from the most severely affected Alzheimer's patients developed the greatest brain abnormalities and memory problems. Rats did not develop these problems when they were injected with samples from people who had no signs of the disease.

For some people, drinking coffee has a laxative effect. Coffee triggers colon contractions and stool movement, a process heightened by its caffeine content. Women prone to constipation might find a morning cup of coffee helpful, but drinking excessive amounts may worsen the symptoms of certain health conditions.

A 2023 study suggests eating more prebiotics—compounds found in plant fiber that nourish healthy bacteria in the gut—may affect the brain's reward network in a way that helps people make healthier food choices.
