Children and adults need at least 20 to 30 grams of fiber per day for good health, but most Americans get only about 15 grams a day. Great sources are whole fruits and vegetables, whole grains, and beans. Soluble fiber, which dissolves in water, can help lower glucose levels as well as help lower blood cholesterol.
(Air travelers are generally not at risk for this disorder because commercial airplane cabins are pressurized.) Congestive heart failure due to high blood pressure, aortic or mitral valve disease, or cardiomyopathy is a common cause of pulmonary edema.
Our Edema Main Article provides a comprehensive look at the who, what, when and how of Edema Pitting edema: Observable swelling of body tissues due to fluid accumulation that may be demonstrated by applying pressure to the swollen area (such as by depressing the skin with a finger). If the pressing causes an indentation that persists for some time after the release of the pressure, the edema is referred to as pitting edema. Any form of pressure, such as from the elastic in socks, can induce pitting with this type of edema.
