This is a condition of abnormally large fluid volume in the circulatory system or in tissues between the body's cells interstitial spaces . In this condition, either too much fluid moves from the blood vessels into the tissues, or not enough fluid moves from the tissues back into the blood vessels. The management of patients with swelling is directed toward the treatment of the underlying medical condition. This is important because excess water retention as it relates to the feet and ankles may be caused by a number of factors and it is very important to know the cause of this condition before it can be properly treated.
This discussion, of course, will be limited to edema of the feet and ankles but it is also possible to have water retention in other parts of the body.
Water retention in the feet, ankles and lower leg is usually described as swelling where the foot appears "bloated". The skin is therefore stretched and in some cases can be shiny as a result. With this swelling there will also be a loss of visual skin structures like the tendons on the top of the foot.
In lymphedema there are instances where the feet and toes are not swollen and the disease affects primarily the leg. This type of manifestation presents with a loss of calf contour and the leg can be described as stove pipe in appearance.
When the foot is affected the appearance typically takes on what is described as a "buffalo hump" where the top portion of the foot is excessively swollen relative to the rest of the foot.
Stage 0-no clinical appearance of lymphedema, mild pitting edema will usually resolve over-night. Lymphedema is diagnosed through vascular testing.
Stage 1-mild pitting edema which usually resolves over-night.
Stage 2-is divided into early stage and late stage. In early stage there is usually pitting edema while in late stage there is no longer pitting but rather brawny edema along with skin changes. Swelling is no longer relieved with elevation.
Stage 3-Elephantiasis characterized by severe non-pitting edema, fibrosis of skin, formation of papillomas and tumors, excessive fat deposition (which may be mistaken for fluid retention), ulceration of skin, as well as cobblestoning of skin.
Excess water retention is usually classified by its severity. The most severe form of swelling is known as pitting edema, also known as brawny edema. You push your finger into the swollen area and the indentation remains after you remove your finger. This is an indication that the swelling is severe and requires medical attention. It is also a sign that this has become a chronic condition.
The depth of the "crater" that is created when you push your finger into the swollen area determines the grade or severity of the swelling. Grade 1 is the least amount of water retention, while Grade 4 is the severest amount.
Non-pitting edema where there is no indentation is usually seen in acute edema, such as seen in a sprained ankle.
The earlier treatment is initiated for this condition, the better the chances of eliminating it or at least controlling it. As stated previously, the most important thing is to accurately diagnose the cause of excess swelling. The problem with ignoring this problem is that it might be a sign of a more serious problem but even if it is not, once a foot has been swollen for a long period of time you end up with brawny edema which is basically permanent swelling that will never subside.
