The science of gerontology has evolved as longevity has improved. Researchers in this field are diverse and are trained in areas such as physiology, social science, psychology, public health, and policy. A more complete definition of gerontology includes all of the following:
Smelly bowel movements are caused by the release of gas. when bacteria, bile or acid mixes with food. Depending on the. food you eat, and where in your digestive tract the mixing. occurs, the combinations can produce various types of gas, all. with different smells.
Some people, for instance, have only three bowel movements per week, while others have three every day. Either pattern may be healthy, depending on the person. Sometimes frequency of bowel movements change, but if the stool looks the same and thereâs no pain, this is most likely not a sign of illness. However, if you begin to experience pain, see blood, or repeatedly pass narrow, ribbon-like stools or loose, watery stools, itâs no laughing matter: time to see a doctor.
