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.
That buildup in turn may produce a change in body odor, according to the Mayo Clinic, and may be a sign it's time to see a doctor. Some people also report a similar change in body odor when switching to a diet heavy in meat and low in carbs. A low-carb diet is known to impact the smell of breath.
