[Answer] How does an Edema occur?

Answer: it occurs when there is an excess of fluid in the ISF and the ICF compartments-can occur because of elevated hydrostatic pressure that is created by diminished osmotic force**excess fluid in the blood->high water pressure->high hydrostatic pressure*in protein starvation hypoalbuminemia(level of albumin in the blood is low) occurs causing more hydrostatic pressure.

Most commonly the legs or arms are affected. Symptoms may include skin which feels tight the area may feel heavy and affected joints may be hard to move. Other symptoms depend on the underlying cause. Causes may include venous insufficiency heart failure kidney problems low protein levels liver problems deep vein thrombosis infections angioedema certain medications and lymphedema. It may also occur due to prolonged sitting or standing and during menstruation or pregnancy. The condition is more concerning if it starts suddenly or pain or shortness of breath is present. Treatment depends on the underlying cause. If the underlying mechanism involves sodium retention decreased salt intake and a diuretic may be used. Elevating the legs and support stockings may be useful for edema of the legs. Older people are more commonly affected. The word is from the Greek οἴδημα oídēma meaning 'swelling'. Specific area An edema will occur in specific organs as part of inflammations tendonitis or pancreatitis for instance. Certain organs develop edema through tissue specific mechanisms. Examples of edema in specific organs: Specific area An edema will occur in specific organs as part of inflammations tendonitis or pancreatitis for instance. Certain organs develop edema through tissue specific mechanisms. Examples of edema in specific organs: • Peripheral edema (dependent edema of legs) is extracellular fluid accumulation in the legs. This can occur in otherwise healthy people due to hypervolemia or maintaining a standing or seated posture for an extended period of time. It can occur due to diminished venous return of blood to the heart due to congestive heart failure or pulmonary hypertension. It can also occur in patients with increased hydrostatic venous pressure or decreased oncotic venous pressure due to obstruction of lymphatic or venous vessels draining the lower extremity. Certain drugs (for example amlodipine) can cause pedal edema. • Cerebral edema is extracellular fluid accumulation in the brain. It can occur in toxic or abnormal metabolic states and conditions such as systemic lupus or reduced oxygen at high altitudes. It causes drowsiness or loss of consciousness leading to brain herniation and death. • Pulmonary edema occurs when the pressure in bl...
