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.
Pale or clay colored bowel movements can mean that your gallbladder or liver is not working correctly. Pencil thin or ribbon-like look to the bowel movements can mean you have a polyp or growth on the inside of the colon or rectum. Presence of food: If the stool breaks up easily and you can see bits and pieces of the food you ate, maybe you are not chewing your food thoroughly enough.
