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.
What's most important is to monitor how you feel and how easily your bowel movements occur. If you're not moving your bowels often enough, you may need to push or strain, and you may feel uncomfortably bloated or gassy. When you do go, the stool may be dry and hard or pellet-like, which are signs of constipation.
