Anasarca
Anasarca is a severe and generalized form of edema, with subcutaneous tissue swelling throughout the body.[1] Unlike edema, which almost everyone will experience at some time and can be relatively benign, Anasarca is a pathological process reflecting a severe disease state and can involve the cavities of the body in addition to the tissues.

Signs and symptoms
Physical appearance
Can include:
- periorbital edema "eye puffiness"
- perioral edema
- upper extremity edema
- ascites
- lower extremity edema
- pre-tibial edema
- pedal edema
Cause
Anasarca is often caused by a decreased oncotic pressure.
Organ Failure
- Liver failure,[2]
- Kidney failure,[3]
- Right-sided heart failure
Diet
- Severe protein deficiency,[4]
Systemic Manifestations of
- Nephrotic syndrome,[5]
- protein-losing enteropathies,[6]
- Capillary leak syndrome.[7]
In Utero
In Hb Barts, the high oxygen affinity results in poor oxygen delivery to peripheral tissues, resulting in anasarca.
Iatrogenic
It can also be caused by the administration of exogenous intravenous fluid.
Diagnosis
Anasarca is a diagnosis made clinically and differentiated from edema by extent of body involvement and severity. While edema is usually graded on mild/moderate/severe scale and usually affects 1-2 regions of the body, Anasarca affects the whole body and is the most severe form of edema with subcutaneous tissue swelling from head to feet.
Testing
While there is no definitive test to prove anasarca, many tests can be useful to aid in the diagnosis. Anasarca is most often seen in conjunction with a low level of albumin
Recent studies have demonstrated a linkage between low-voltage electrocardiogram (ECG) (LVE) (QRS complexes of <5 mm in the limb and <10 mm in the precordial leads) and Anasarca.[8]
Treatment
Anasarca is a severe symptom, not a pathological process in and of itself; as such, the best treatment is to treat the underlying cause. However, there are a number of things that can be done to help get the fluid off as well as prevent further accumulation of fluid.
Diuretics
One of the mainstays of any edema treatment, diuretics are a category of medications that help the body pee out fluid by altering the way in which the kidney processes urine.
Diet
The body more efficiently absorbs fluid from the gut and retains that fluid with the help of sodium and sugar. As such, decreasing salt and simple sugar intake will help prevent accumulation of fluid and potentiate the effect of any diuretics. Following a high protein diet will help provide your body with the substrates necessary to produce albumin, the major protein in human plasma and the single most important molecule in maintaining the serum oncotic pressure.
Fiber
Bulking fiber, both soluble and insoluble dietary fiber, absorb water throughout your GI tract. Viscous fiber can thicken the contents of the GI track and slow the absorption of other compounds (like simple sugars).
