What Causes Edema?

It has a wide variety of reasons. Simple reasons might include sitting or standing for longer periods of time and more complex reasons include some serious underlying diseases.

Varicose Veins

Heart Failure

It is one of the most common reasons of Edema in legs. This condition is caused by the inefficiency of heart to pump sufficient blood your body needs leading to fluid buildup especially in your legs.

Kidney Failure

One of the main symptoms of kidney failure is Edema. It occurs because the damaged kidneys do not work properly and are unable to remove the waste products and fluids from blood causing the buildup of excess fluids in your body.

Injury 

Swelling often results in response to a broken bone, sprain, strain or severe bruising causing excruciating pain.

Inflammation in legs is also caused by teared ligament or tendon leading to the swelling of the tissues in your legs. 

Malnutrition

It results in response to a protein deficient diet. It causes fluid accumulation leading to Edema in both the legs.

Cellulitis

Excess Intake of Salt

Pregnancy

It can occur in different parts of the body but in 50% cases it occurs in legs.

Long periods of inactivity

As cliché as it may sound “obesity is the mother of all problems” and so is in this case of Edema. No wonder if you are overweight your excess body weight  kickstarts Edema by causing extra pressure on veins.
