What is caused by excessive loss of body fluid?
The body may lose too much fluid due to diarrhea, vomiting, severe blood loss, or high fever. Lack of a hormone called antidiuretic hormone (ADH) can cause the kidneys to get rid of too much fluid. This results in extreme thirst and dehydration. Often, a high or low level of sodium or potassium is present as well.
What causes the body to retain fluid?
Fluid retention or edema means that there is excessive water in the tissue of the body which causes the body to swell, especially in the extremities.Fluid retention is often caused by the increase of blood pressure on the veins which adds to the pressure on the capillaries.
Why does my abdomen swell?
Congestive heart failure can also cause swelling in your abdomen. Sometimes, this condition can cause fluid to accumulate in your lungs (pulmonary edema), which can lead to shortness of breath. Cirrhosis. Fluid may accumulate in your abdominal cavity (ascites) and in your legs as a result of liver damage (cirrhosis).
What causes edema in the legs?
Kidney disease. When you have kidney disease, extra fluid and sodium in your circulation may cause edema. The edema associated with kidney disease usually occurs in your legs and around your eyes. Kidney damage. Damage to the tiny, filtering blood vessels in your kidneys can result in nephrotic syndrome.
How do you know if you have edema?
Signs of edema include: Swelling or puffiness of the tissue directly under your skin, especially in your legs or arms. Stretched or shiny skin. Skin that retains a dimple (pits), after being pressed for several seconds. Increased abdominal size.
What is swelling in the hands and feet?
Edema is swelling caused by excess fluid trapped in your body's tissues. Although edema can affect any part of your body, you may notice it more in your hands, arms, feet, ankles and legs.
What happens if you have a nephrotic disease?
In nephrotic syndrome, declining levels of protein (albumin) in your blood can lead to fluid accumulation and edema. Weakness or damage to veins in your legs.
Why does my body retain more water and sodium while pregnant?
If you are pregnant, your body retains more sodium and water than usual due to the fluid needed by the fetus and placenta. This can increase your risk of developing edema. Your risk of edema may be increased if you take certain medications, including: High blood pressure medications.
Why does my calf muscle swell?
Sudden onset of swelling in one leg accompanied by pain in your calf muscle can be due to a blood clot (deep vein thrombosis , or DVT) in one of your leg veins. If this occurs, seek medical help immediately. Inadequate lymphatic system. Your body's lymphatic system helps clear excess fluid from tissues.
What causes fluid accumulation in the interstitial space?
A large number of conditions can cause fluid accumulation in the interstitial spaces by the abnormal leaking of fluid from the capillaries or by preventing the lymphatics from returning fluid from the interstitium back to the circulation. The following is a partial list of conditions that can cause extracellular edema by these two types ...
What causes extracellular fluid edema?
There are two general causes of extracellular edema: (1) abnormal leakage of fluid from the plasma to the interstitial spaces across the capillaries, and (2) failure of the lymphatics to return fluid from the interstitium back into the blood. The most common clinical cause of interstitial fluid accumulation is excessive capillary fluid filtration.
What causes a decrease in plasma concentration of proteins?
A reduction in plasma concentration of proteins because of either failure to produce normal amounts of proteins or leakage of proteins from the plasma causes the plasma colloid osmotic pressure to fall . This leads to increased capillary filtration throughout the body as well as extracellular edema.
Why does edema occur when lymphatic blockage occurs?
When lymphatic blockage occurs, edema can become especially severe because plasma proteins that leak into the interstitium have no other way to be removed. The rise in protein concentration raises the colloid osmotic pressure of the interstitial fluid, which draws even more fluid out of the capillaries.
Why is the safety factor against edema lost?
Thus, in the positive tissue pressure range, this safety factor against edema is lost because of the large increase in compliance of the tissues.
What is edema in the body?
Edema refers to the presence of excess fluid in the body tissues. In most instances, edema occurs mainly in the extracellular fluid compartment, but it can involve intracellular fluid as well.
What causes edema in the heart?
Edema Caused by Heart Failure . One of the most serious and most common causes of edema is heart failure. In heart failure , the heart fails to pump blood normally from the veins into the arteries; this raises venous pressure and capillary pressure, causing increased capillary filtration.
What is the term for an abnormal accumulation of fluid in the body cavity?
Effusion refers to an abnormal accumulation of fluid in a body cavity. This condition is also known as water retention because a major proportion of the accumulated fluid is usually water. Sometimes, however, other components such as blood and pus may also constitute a part of the accumulated fluid. Effusion should not be confused ...
What happens when fluid is in the body cavity?
Accumulation of fluid in the body cavities may lead to compression of nearby tissues. This could lead to constriction of nearby blood vessels, resulting in a reduction or total loss of blood supply to the tissues. A lack of blood supply leads to the death of the tissue, which can compromise the function of the affected organs. For example, breathing may become difficult when lung tissue is affected by effusion.
What is the term for the presence of pus in the accumulated fluid?
The presence of these proteins in body cavities may lead to scar tissue formation. Purulent effusion: Also known as suppurative effusion, purulent effusion refers to the presence of pus in the accumulated fluid. The amount of pus in the accumulated fluid may vary. Hemorrhagic effusion: Hemorrhagic effusion refers to the presence ...
How do you know if you have an effusion?
Signs and Symptoms. In the initial stages, effusion does not elicit any signs and symptoms. Only when excess fluid accumulation causes swelling, signs and symptoms may appear. The following are some of the key signs and symptoms of effusion: Swelling: The main sign of effusion is localized swelling in the affected region.
What causes pleural effusion?
Pleural effusion can be caused by a variety of conditions such as pneumonia, pleuritis, asbestosis, pulmonary tuberculosis, cancer, pulmonary embolism, kidney disease, liver disease, heart failure and trauma to the chest. Read more on fluid in the lungs.
What causes a swollen lining in the body cavity?
The causes of effusion depend on the site of effusion. Inflammation of the membranous linings of the body cavities is one of the main causes of effusion. Infections, trauma, medications, chemotherapy, radiotherapy, hepatic disease, renal failure, and heart failure can all cause effusion.
Which effusion contains a large amount of fibrin and fibrinogen proteins?
Serous effusion: In serous effusion, the accumulated fluid has very little protein, and is similar in composition to the tissue fluids or serum component of the blood. Fibrinous effusion: Fibrinous effusion contains a large amount of fibrin and fibrinogen proteins. These proteins are critical for the formation of blood clots.
What is the disorder of fluid accumulation in the interstitial tissue around the air spaces?
An accumulation of fluid in the interstitial tissue around the air spaces (alveoli) in the lungs occurs in a disorder called pulmonary edema.
What is edema in the body?
Share Your Story. The definition of edema is observable swelling from fluid accumulation in body tissues. When parts of the body are affected with edema, they are considered edematous. Edema most commonly occurs in the feet, ankles, legs, and/or hands where it is referred to as peripheral edema.
Why does edema occur?
In these diseases, edema occurs primarily because of the body's retention of too much salt (sodium chloride). The excess salt causes the body to retain water, which then leaks into the interstitial tissue spaces, where it appears as edema. Medications also can cause pitting edema.
How to tell if you have pitting edema?
Symptoms of pitting edema include swelling, which causes the skin surrounding it to tighten, the position that you are in will affect edema, and the skin over the swollen area appears shiny and light , and, often when a finger is placed on the swollen area and indentation is left on the skin .
Why does my leg swell?
Leg swelling generally occurs because of an abnormal accumulation of fluid in the tissues of the lower extremity. Persisting indentation of a swollen leg after pressure from a finger is known as pitting edema . Common causes of leg swelling include. salt retention, cellulitis, congestive heart failure, and.
What is the swelling of the foot called?
Edema of the foot is sometimes called pedal edema. The swelling is the result of the accumulation of excess fluid under the skin in the spaces within the tissues. All tissues of the body are made up of cells, blood vessels, and connective tissues that hold the cells together called the interstitium.
Why does salt cause edema?
In both conditions, the amount of salt in the body increases, which causes the patient to retain water and develop edema. People with edema experiencing a disturbance in their ability to normally excrete salt may need to either be placed on a diet limited in salt and/or given diuretic medications (water pills).
