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.
I have always been regular, having bowel movements once per day that were well formed, and left me feeling fully evacuated. About 18 months ago, my stools began getting very soft and greasy. I also became a producer of very foul-smelling gas (quite unpopular with the family, though a source of some amusement for the kids). After about 8 months, I talked to my physician about it.
