Inflammatory bowel disease (IBD) Archive

Virtually everyone carries the bacteria Clostridioides difficile, or C. diff. But half a million Americans a year develop a serious C. diff infection due to a gut microbiome imbalance. It disproportionately strikes people in hospitals and nursing homes, and can recur repeatedly.

"Regular" bowel movements can mean something different for each person. Some people have a bowel movement once or twice daily; for others, it's once or twice weekly. People should see a doctor if they notice a dramatic change in bowel habits or other symptoms, including fatigue, pain, unintended weight loss, bloody stool, or a change in stool consistency. People can promote digestion by maintaining a toileting schedule, heeding their body's signals, and using a toilet stool.

Following a plant-based eating pattern and cutting back on highly processed foods can help promote a more diverse, healthier microbiome. A healthy gut microbiome may decrease inflammation that promotes heart disease. Most fruits, vegetables, beans, and whole grains are good sources of prebiotic fiber, which is broken down by gut bacteria to create short-chain fatty acids. These fatty acids are linked to lower inflammation and reductions in other heart disease risk factors.

The human body has hundreds of lymph nodes, one part of the immune system that helps defend the body against health threats. They aren't usually noticeable, but they are always working to deal with potential health problems.

Eating two peeled kiwifruits per day may help ease constipation, according to a small randomized trial published in 2023. The effectiveness of eating kiwifruits was slightly greater than that of using a daily fiber supplement such as Metamucil or Fiberall.

A 2023 study suggests that women who have used menopausal hormone therapy are significantly more likely to develop gastroesophageal reflux disease (GERD).

Who should get COVID vaccine boosters and when will remain in flux for at least another year. This summer, the FDA instructed the vaccine makers to have the next COVID vaccine target the XBB.1.5 Omicron subvariant. The CDC will be issuing specific recommendations by October, but infectious disease experts expect the newer vaccine to provide the most benefit for people over 65 and those younger with chronic conditions.

The thymus gland is very important in the development of the immune system during fetal growth, infancy, and early childhood. As we grow into adulthood the thymus shrinks, but growing evidence suggests the gland may play a role in adult health for much longer than previously thought.

In the US population as a whole, deaths from colon cancer have been declining, but in people under 50 that rate has increased. Most major medical organizations recommend screening beginning at age 45 for people at average risk.

Removing tonsils in childhood was once routine care for healthy children, but is no longer recommended. Why are some organs and glands — appendix, tonsils, adenoids and more — considered expendable and why do we have them if they're not needed?
