Edema not all is nephritis how to diagnose nephritis?

Early symptoms of nephritis
Acute nephritis 1 to 3 weeks before the onset of acute respiratory tract or streptococcal infection history, such as pharyngitis, tonsillitis, scarlet fever, suppurative skin diseases. Chronic are mostly found in physical examination. More manifestations of mild to moderate edema, hypertension and renal impairment. There may be mild nausea and vomiting, difficulty breathing, skin itching and fatigue and other symptoms. Early symptoms are not obvious, if found suddenly found persistent morning facial and lower extremity edema, as soon as possible to the hospital for examination.

Therefore, many people have edema, are considered associated with nephritis. In fact, in the outpatient encounter "edema" who are not all nephritis. What is the cause of edema?

What is the reason for edema?
First, the 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. Accompanied by a large number of proteinuria produce more people need attention, this is due to kidney problems. 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.

Second, the capillary hydrostatic pressure increased
Increased hydrostatic pressure in the capillaries is also a major contributor to edema, leading to venous obstruction or venous return disorder. As the venous return in the body fluid circulation is blocked, the capillary fluid pressure increases, in the corresponding parts of the obstruction will produce water or edema. 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. This is the second largest aspect of induced edema.

Third, the capillary wall permeability increased
In the third aspect, the same is due to the cause of capillaries, the permeability of the capillary wall increases, making the body fluid circulation process hindered. 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.

Fourth, lymphatic reflux blocked
Lymph flow is a major part of the body fluid circulation, when the lymph circulation is damaged, the incidence of edema is very large. For example, when the radical mastectomy, due to part of the lymph nodes removed, the body's local lymph circulation has been damaged, may cause side of the upper part of the edema. Some other diseases, if the lymphatic obstruction or produce other problems, leading to lymphatic drainage blocked, then often cause local edema, so the lymphatic reflux is also a major cause of edema.

What should I do before diagnosing nephritis?
1, want to diagnose whether the nephritis, need to do routine urine can be ruled out, if the urine protein negative, microscopic examination is also OK on the normal. If the urine protein is positive, there are red blood cells, white blood cells, the best in the test of renal function, for color ultrasound. Nephritis check urine routine can be found, simply for B-diagnosis of nephritis is not valuable.

2, common symptoms of nephritis, such as "edema, low back pain" and so on. Do not want to guess their own at home, must go to the regular hospital, the doctor will give you to do the relevant checks, symptomatic treatment. Check urine can be found out. Winter to keep warm, in the winter, the patient's condition easily deteriorated, because the blood vessels easily shrink at low temperatures, the kidney vulnerable to damage.

3, not to take medicine, many pharmacies painkillers, cold medicine and herbs have a side effect on the kidneys, do not eat, especially those who are not regular remedies. The antibiotics and painkillers of the doctor should also know what side effects. Not overeating, diet contains protein and salt more, will increase the burden on the kidneys.
