This is because the heart is too weak to pump blood around the body properly, so the blood gathers in front of the heart. Because of this, and due to the increased blood pressure in the veins, fluid seeps out into the surrounding tissue. This may cause swelling in the legs or a build-up of fluid in the abdomen.

If the person spends a lot of time lying down, the edema might show up on his or her back called sacral edema. Congestive heart failure can also cause edema in the lungs pulmonary edema.

This is not common, but the condition is life-threatening.

Edema: Part 1

It means the lungs are filling with fluid because the left side of the heart is not strong enough to pump the blood returning from the lungs. The blood gathers in the blood vessels of the lung, and fluid seeps out into the lung tissue.

Why Does High Blood Pressure Cause Edema in the Legs and Feet? |

The signs are shortness of breath and rapid, shallow breathing or coughing. Kidney disease could cause edema in the legs and around the eyes, because when the kidneys do not remove enough sodium and water from the body, the pressure in the blood vessels starts building up, which can lead to edema.

Low protein levels in the blood: If there is a lack of the protein albumin in the blood, fluid can leak out of blood vessels more easily.

Low protein in the blood can be caused by extreme malnutrition, as well as kidney and liver diseases which mean that the body loses too much or produces too little protein. Scarring of liver tissue liver cirrhosis due to, for instance, long-term alcohol abuse or a liver inflammation, can cause edema in the abdomen called ascites. This is because cirrhosis causes a lack of proteins and congestion in the liver, which can lead to increased pressure in the blood vessels.

As a result, fluid seeps out into the abdomen. Chronically high blood pressure places excess strain on your heart, which may cause it to wear out and fail. Heart failure diminishes blood flow and in response, your body tends to retain fluid in an effort to maintain adequate blood volume. But a failing heart is unable to accommodate this extra fluid, so it is transferred out of your blood vessels and into your tissues -- usually in those body parts that are lower than others.

So, edema in your legs and feet could be the result of heart failure caused by uncontrolled high blood pressure. Kidney Failure Your kidneys help control your blood pressure by altering sodium and water absorption in response to changes in blood pressure. If your blood pressure falls, your kidneys absorb more salt and water to bring your pressure back up. Damage to the tiny, filtering blood vessels in your kidneys can result in nephrotic syndrome. 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. If you have chronic venous insufficiency, the one-way valves in your leg veins are weakened or damaged, which allows blood to pool in your leg veins and causes swelling. 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. Your body's lymphatic system helps clear excess fluid from tissues.
