What reason can edema cause obstruction

summary

Edema is due to the accumulation of excessive fluid in the tissue space or body cavity. The causes of edema are mainly due to the imbalance of fluid exchange inside and outside the blood vessels and the imbalance of fluid exchange outside the body. The imbalance of intra - and extra vascular fluid exchange included the increase of capillary hydrostatic pressure, the decrease of plasma colloid osmotic pressure, the increase of capillary wall permeability and the obstruction of lymphatic reflux. The imbalance of fluid exchange inside and outside the body mainly includes the decrease of glomerular filtration rate, the increase of sodium absorption from proximal convoluted tubules, and the increase of sodium absorption from distal tubules and collecting tubules.

What reason can edema cause obstruction

First: in normal life, the most common edema is cardiogenic edema, renal edema and hepatitis edema. The edema of new humanity generally appears in the lower limbs of the body first, and is most obvious in the ankle. In severe cases, it can spread all over the body. Renal edema, generally from the face, to the end can also be all over the body. The main manifestation of hepatic edema was ascites.

Second: according to the causes of edema, it can be divided into cardiogenic edema, hepatic edema, renal edema, inflammatory edema and lymphedema. According to the scope of edema, it can be divided into localized edema and systemic edema. According to the location of the elder, it can be divided into subcutaneous edema, pulmonary edema and brain edema.

Third: if brain edema can occur intracranial hypertension or the formation of brain hernia and death. And pulmonary edema can cause dyspnea, severe respiratory failure can occur. Laryngeal edema can lead to asphyxia. Who find easily lead to circulatory disorders, reduced resistance, prone to infection.

matters needing attention

Can be more bed rest, to carry out appropriate activities. To establish a healthy and good eating habits, eat more foods rich in vitamins, protein, calories and cellulose. You can eat more fresh fruits and vegetables. If the ascites is too much, you can pump water and massage when the lower limbs are edematous.
