What is physiological edema?
It is called physiologic edema. Fluid accumulates during pregnancy because the adrenal glands produce more of the hormones that make the body retain fluids (aldosterone and cortisol). Fluid also accumulates because the enlarging uterus interferes with blood flow from the legs to the heart.
What is the mechanism of edema?
Pathophysiology of Edema Edema results from increased movement of fluid from the intravascular to the interstitial space or decreased movement of water from the interstitium into the capillaries or lymphatic vessels. The mechanism involves one or more of the following: Increased capillary hydrostatic pressure.
What is the mechanism of edema in inflammation?
The swelling process, also known as edema, is the result of acute inflammation, a response triggered by damage to living tissues. In the case of injury, the purpose of the inflammatory response is to remove components of damaged tissue in order to allow the body to begin to heal.
What does pitting edema mean?
Pitting edema is when a swollen part of your body has a dimple (or pit) after you press it for a few seconds. It can be a sign of a serious health issue.
What causes edema physiology?
Edema results from increased movement of fluid from the intravascular to the interstitial space or decreased movement of water from the interstitium into the capillaries or lymphatic vessels. The mechanism involves one or more of the following: Increased capillary hydrostatic pressure. Decreased plasma oncotic pressure.
What is the difference between edema and pitting edema?
Edema is swelling in the body caused by excess fluid. It often affects the lower body, such as the legs, feet, and ankles, but it can occur anywhere. If you press on a swollen area and an indentation or pit remains, it’s called pitting edema.
Is some pitting edema normal?
Pitting edema is a common symptom. It is usually not a cause for concern in itself, but many underlying conditions require treatment, sometimes urgently. Edema should not cause any long-term complications. After working with a doctor, many people find lasting relief from the symptom.
Where do you check for pitting edema?
Tests that can aid in a diagnosis of pitting edema include:
- a physical exam.
- imaging tests, such as X-rays, which can show fluid retention and problems in the lungs.
- blood tests.
- urine tests.
- an echocardiogram, which is an ultrasound scan of the heart.
What is the difference between pitting and non-pitting edema?
Pitting edema responds to pressure, be it from a finger or a hand, while pitting edema does not. If you press on your skin with your finger and it leaves an indentation, you could be suffering from pitting edema. Non-pitting edema, on the other hand, does not respond to pressure or cause any sort of indentation.
