The accumulation of an excess volume of fluid, including blood, in an organ or tissue. I use it in the subclinical definition, with fluid buildup as a consequence of unremitting inflammation, with edema of the parts, and resultant venous and lymphatic drainage, impairment, causing a distinctly less organic and more functional problem: thick and boggy tissues from excess inflammation.
Abnormal collection of blood or other fluid (e.g., mucus, bile), as in the lungs (pulmonary congestion).
An accumulation of blood within an organ, which is the result of back pressure within its veins (for example congestion of the lungs and liver occurs in heart failure). Congestion may be associated with edema (accumulation of fluid in the tissues). It is relieved on treatment of the cause.
The accumulation of blood or other body fluid in a particular part of the body. The condition may be due to some failure in the circulation, but as a rule is one of the early signs of inflammation.
An excessive amount of blood or tissue fluid in an organ or in tissue.
The term “edema” typically describes the buildup of excessive blood, tissue fluid, or lymph in a specific area of the body.
An elevated blood flow to a particular region as a result of inflammation is a primary contributor to congestion. Additionally, reduced blood drainage from an affected area can also lead to congestion. This can occur in conditions such as heart failure, venous disorders including varicose veins, and lymphatic disorders.
