The Pathophysiology of Edema

Paper Summary:

This paper explains that there are two causes of edema: a change in the fluid exchange system of the body, and an increased level of sodium bought about by its retention by the kidney. The paper points out that, for treating swollen legs, it is best to begin with simple exercises and postures (leg raise); in most cases of non-systemic peripheral edema, these simple treatment methods will reverse the condition. The paper stresses that, unless it is an emergency, the use of diuretics should be minimized, as it may result in complications resulting from over-diuresis.

From the Paper:

"Pulmonary edema also known as "Lung water" or "Pulmonary congestion" is a condition where fluid accumulates inside the lungs leading to respiratory difficulties. The chief cause for this problem is the decreased activity of the heart resulting in increased pressure on the pulmonary veins. As a result, fluid is forced into the alveoli and this directly interferes with the gaseous exchange mechanism leading to shortness of breath."
