Weefseloedeem

Weefseloedeem is a medical term used to describe tissue edema, the accumulation of excess fluid in the interstitial spaces of the body's tissues, which leads to swelling. It can be localized to a single area or generalized, and may affect skin, subcutaneous tissue, or mucous membranes.

The condition arises from imbalances between fluid filtration and reabsorption in capillaries or from impaired drainage of lymphatic fluid. Contributing factors include increased capillary hydrostatic pressure (such as from heart failure or venous insufficiency), decreased plasma oncotic pressure (such as from hypoalbuminemia), and increased capillary permeability due to inflammation or infection. Obstruction or malfunction of the lymphatic system can cause localized lymphedema. Medications, pregnancy, and prolonged immobility can also contribute to edema.

Common etiologies encompass cardiovascular disease, kidney disease, liver disease, pregnancy, obesity, and prolonged standing or sitting. Localized edema can follow trauma, surgery, or infection. The presentation typically includes swelling that may be pitting on examination, a sense of heaviness or tightness, and skin changes; in severe cases, pain, limited range of motion, or skin ulcers can occur.

Diagnosis relies on clinical assessment and targeted tests to identify the underlying cause. This may include measurement of limb circumference, blood tests, imaging to evaluate heart or kidney function, and ultrasound to exclude venous thrombosis. In suspected lymphatic disease, specialized assessments may be used.

Treatment focuses on addressing the underlying cause and reducing fluid buildup. Management options include compression therapy, limb elevation, salt restriction, and, when appropriate, diuretics. Physical therapy and skin care are important to prevent complications, and lymphedema-specific therapies such as manual lymph drainage and compression garments may be recommended.

Etymology: the term derives from Dutch weefsel (tissue) and oedeem (edema). It is used primarily in Dutch-speaking medical contexts and in cross-linguistic medical literature.
