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.
A bowel movement is the last stop in the movement of food through your digestive tract. Your stool passes out of your body through the rectum and anus. Another name for stool is feces. It is made of what is left after your digestive system (stomach, small intestine, and colon) absorbs nutrients and fluids from what you eat and drink. Sometimes a bowel movement isn't normal. Diarrhea happens when stool passes through the large intestine too quickly.
