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.

Burping is often seen (and heard) as something rude and crude, but it serves an essential purpose by preventing the stomach from overinflating with air from eating.

The first-ever guidelines to diagnose chest pain document the range of possible heart attack symptoms. They include a sense of pressure, tightness, squeezing, or heaviness in the chest but also in the shoulders, arms, neck, back, upper abdomen, or jaw. The report also provides a road map to help doctors assess chest pain with selective use of the latest available tests. Chest discomfort can also result from other conditions that affect the heart (such as pericarditis) and nearby organs. These include acid reflux, muscle or joint issues, and lung problems.
