Edema is not necessarily nephritis

2017-09-26 18:03
Chronic nephritis patients were found only in physical examination. More manifestations of mild to moderate edema, hypertension and renal impairment. Then the edema must be nephritis? In fact, there are many causes of edema, not necessarily nephritis. The following is a detailed description of the causes of edema.
The hydrostatic pressure in the capillaries increases
Increased hydrostatic pressure in the capillaries is also a major contributor to edema, leading to venous obstruction or venous return disorder. Hepatic hardening caused by gastrointestinal wall edema is one of them. In addition, in the human heart failure, the resulting vena cava reflux disorder may also cause edema, and also systemic.
Plasma colloid osmotic pressure decreased
This is due to malnutrition, the absorption of the intake of protein is not sufficient, can not provide adequate physical activity of the body enough energy. When the amount of protein in the plasma drops to a certain extent, the plasma colloid osmotic pressure is reduced, the probability of edema is very large, and often is systemic edema.
Capillary wall permeability increased
Increased permeability of the capillary wall, so that the body fluid circulation process is hampered. Vessels in the active substances such as histamine, kinin, bacterial toxins will increase the permeability of the capillary wall. Inflammatory lesions of edema is due to this cause, the site of vascular wall damage is the high incidence of edema, vascular edema is the case, common in the vascular wall of the site.
