By edema excessive fluid gather in body parts or greater areas of the body, making the areas swollen. Edema is most often a problem in the legs, but can occur anywhere in the body.

There are several types of edema, and many cases are also a mixture of more than one type. By lymphedema the drainage from the tissues through the lymph vessels are impaired or excessive fluid goes through the blood capillary walls into the spaces between the cells in a tissue. Edema can also occur because of poor drainage of blood through the veins towards the heart. Edema can further be caused by general accumulation of excessive fluid in the body.

The causes of edema are many. Edema is a symptom by most inflammations. Insufficient heart action by congestive heart failure can cause edema. A too high intake of salt can cause general water retention in the body. Sitting and standing long in the same position can cause edema in the lower limbs. A still sitting life without exercise can cause or aggravate edema. Insufficiencies of the liver or kidneys can cause fluid retention and thereby edema. Edema can be a side effect of antihypertensive drugs, steroids surgery and radiation therapy. Further causes of different types of edema are varicose veins, cancer, hypothyroidism, blood clots, constipation and physical injuries.

To treat edema, it is important to treat the underlying disease or injury. However, medical treatment does not always cure the underlying condition or the cause is wholly or partially lifestyle aspects. Therefore various measures targeted directly against the edema are useful. These are presented here:

Pharmacological treatments: The physician will sometimes prescribe diuretics to reduce fluid retention in the body and thereby reduce edema. This treatment should however be used for serious edema or edema persistent when other measures do not work.

Salt intake restriction: Restriction of salt intake is an important measure by edema. People suffering from edema should avoid adding great amount of salt into their food or consume preprocessed food with a salty taste.

Diet: A good general diet that alleviates chronic inflammation is useful. The diet should especially contain enough sources of omega-3-fatty acids and monounsaturated fatty acids, like: Fat fish, seafood, flax oil, olive oil, almonds, rape oil and canola oil. Also vegetables and fruit in a natural shape are useful.

Avoiding constipation: Constipation should be treated, since a stomach engorged by excessive content can cause impairment of fluid circulation.

Variation of corporeal position: You should avoid sitting or standing still a long time during the day. When sitting during work or rest, you should change position with regular intervals.

Exercise: Every day you should have some exercise adjusted to your health condition. This could be walking, cycling, swimming, running or any other sport activity where you use greater parts of your body. Doing regular stretching exercises or yoga is useful. By severe edema special therapeutic exercises should be prescribed by a professional. High position of limb: When you are sleeping or resting the swollen body parts can be placed in an elevated position by means of pillows, pads or by resting in an adjustable bed or chair.
