What causes dependent edema?
Edema is a normal response of the body to inflammation or injury. For example, a twisted ankle, a bee sting, or a skin infection will all result in edema in the involved area. In some cases, such as in an infection, this may be beneficial. Increased fluid from the blood vessels allows more infection-fighting white blood cells to enter the affected area.
Edema can also result from medical conditions or problems in the balance of substances normally present in blood. Some of the causes of edema include:
Low albumin (hypoalbuminemia): Albumin and other proteins in the blood act like sponges to keep fluid in the blood vessels. Low albumin may contribute to edema, but isn’t usually the sole cause.
Allergic reactions: Edema is a usual component of most allergic reactions. In response to the allergic exposure, the body allows nearby blood vessels to leak fluid into the affected area.
Obstruction of flow: If the drainage of fluid from a body part is blocked, fluid can back up. A blood clot in the deep veins of the leg can result in leg edema. A tumor blocking lymph or blood flow will cause edema in the affected area.
Critical illness: Burns, life-threatening infections, or other critical illnesses can cause a whole-body reaction that allows fluid to leak into tissues almost everywhere. Widespread edema throughout the body can result. Visit at expelis reviews.
Dependent edema results from a build-up of fluids within the skin. During the day, gravity normally pulls fluids to the lower parts of the body, especially the feet and ankles, causing some swelling. What should be done about dependent edema? If swelling is constant throughout the day, getting worse, accompanied by shortness of breath, or general weight gain, it could signal other medical problems. See your doctor for an evaluation. However, if swelling is better in the morning, and there are no other problems, try these suggestions: • Keep your feet up as much as possible. At least 3 times a day, rest with your feet about 1 foot above the level of your heart for 10 to 15 minutes. • Make sure you get some regular exercise. This will improve the circulation in your legs and feet. Simply taking a walk each day is a good way to start. • Maintain your proper weight. Excess weight slows the circulation of body fluids and puts extra pressure on your veins, causing fluids to build up under yo
