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.
Constipation can cause bad body odor, and almost always does. This is because when one has constipation, food takes too long to pass through the intestines. When food sits in the intestines for a day or even longer in some cases, certain toxins are reabsorbed, and these cause various odors, none of which are pleasant.
