In medical parlance,<unk> is the enlargement of organs caused by accumulation of excess fluid in tissues, called edema.
It can occur throughout the body (generalized), or a specific part or organ can be affected (localized).<unk> is considered one of the five characteristics of inflammation; along with pain, heat, redness, and loss of function.
In a general sense, the suffix "-megaly" is used to indicate a growth, as in hepatomegaly, acromegaly, and splenomegaly.
A body part may swell in response to injury, infection, or disease, as well as because of an underlying lump.<unk> — especially<unk> of the ankle can also occur if the body is not circulating fluid well.
Generalized<unk>  or massive edema (also called anasarca), is a common sign in severely ill people. Although slight edema may be difficult to detect to the untrained eye, especially in an overweight person, massive edema is very obvious.
