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.
Bottle-fed babies often need to open their bowels daily, as the stools are bulkier. Bottle-fed baby stools smell worse (more like an adult's). It is not uncommon for your baby's stools to vary in colour and consistency from day to day. Any prolonged change to harder, less frequent stools might mean constipation.
