AHA News: Quitting Smoking Could Lead to Major Changes in Gut Bacteria

FRIDAY, Nov. 15, 2019 (American Heart Association News) -- Quitting smoking leads to major changes in intestinal bacteria, according to new research. But just what the changes mean will need further investigation.

The small pilot study, to be presented Monday during the American Heart Association's Scientific Sessions in Philadelphia, comes in the wake of past research showing a link between bacteria in the gut and cardiovascular health. That past work has shown smoking is associated with a decrease in diversity in the types of beneficial bacteria living in the gut.

Popular Heartburn Drugs May Up Odds of Stomach Bug

WEDNESDAY, Nov. 27, 2019 -- If you're one of the millions who rely on medications known as proton pump inhibitors for relief from heartburn, you may be at higher risk of illness from a stomach bug, new research suggests.

Sooner Is Usually Better for Gallbladder Surgery

THURSDAY, Oct. 31, 2019 -- If someone is hospitalized for a painful gallbladder attack, new research suggests that surgery probably shouldn't wait.

Doctors may typically hold off on operating until gallbladder inflammation has gone down and antibiotics have started working on an infection. But the study found that waiting more than 72 hours for surgery led to a higher rate of complications and longer hospital stays.

Many Common Meds Could Alter Your Microbiome

WEDNESDAY, Oct. 23, 2019 -- Some widely used drugs alter the population of microbes in the gut, and a number raise the risk of antibiotic resistance, a new Dutch study shows.

The gut microbiome includes at least 1,000 species of bacteria and is influenced by a number of different factors, including medication. Research suggests that changes in the gut microbiome are associated with obesity, diabetes, liver diseases, cancer and neurodegenerative diseases.
