There is a constant balancing act that takes place within your body. When it comes to the levels of salt maintained in the body, the kidneys along with a number of hormonal and physical factors regulate the amount of salt retained and removed from the body. Your diet will determine the amount of salt you take in and the kidneys then control the amount of salt excreted via the urine. In case you suffer from medical conditions such as heart disease, diabetes or any type of kidney problems, there is a decrease in the blood flow to the kidneys. In response to this decrease, the kidneys start retaining more salt to maintain the fluid balance in the body. This results in water retention and edema. There are two main types of edema that can affect a person – pitting and non-pitting. When you press down on a swollen area and the indentation is left behind on the skin, it is known as pitting edema. Non-pitting edema does not cause any such indentations.
Q. what is "pulmonary edema" and what are the risks? my Dr. told me I'm in a risk group for pulmonary edema, he tried to explain what it is but i didn't understand fully...if someone may give me a brief explanation- I'll appreciate it! A. pulmonary edema occurs when, lets say, your heart left ventricle stops working properly and your right ventricle works fine. that means your lungs getting lets presume- 1 liter of blood -but your left ventricle can pump out of it only 990 ml. that means you have high blood pressure in your lungs and fluid comes out of blood vessels and fills your lungs, making it harder and harder breathing.
Edema is a form of swelling caused by excess fluids trapped in the tissues of your body. It is most commonly found at the ankles, feet, legs, arms and hands. Edema can be a result of a temporary condition such as during pregnancy or after an injury. Edema can also result from heart, kidney or liver disease, or it can be a side effect of a medication. Edema can also be peripheral, which means it is found in the ankles, feet, legs, arms, and hands, or it can be central, which means it is found around internal organs such as the lungs.
