Acute glomerulonephritis (acute nephritis) is more common in children, more males than females, and usually develops 1 to 3 weeks after a prodromal infection. Acute glomerulonephritis has an acute onset and varies in severity, but most of the disease has a good prognosis and can often heal itself within a few months. So, what are the symptoms of acute glomerulonephritis? The typical symptoms of acute glomerulonephritis 1, prodromal symptoms Acute glomerulonephritis has a history of whistling or skin infections such as acute pharyngitis, tonsillitis, chicken pox, measles, skin pustules, etc. 1 to 3 weeks before the onset of acute glomerulonephritis, some patients may have no obvious prodromal symptoms. 2, urine abnormalities (1) carnal hematuria: often one of the first symptoms of acute glomerulonephritis, the urine color deepens to cloudy brown-red or wash water-like, generally hematuria will last for a few days and then disappear, but can last for several weeks before disappearing, but it takes about 6 months for urinalysis to be normal, or can last 1 to 3 years before returning to normal. (2) Proteinuria: Some patients may also develop proteinuria, which is characterized by increased foam in the urine and increases or decreases with the severity of the lesion. Proteinuria disappears more slowly than other symptoms, and after the edema disappears, proteinuria can continue for some time before gradually subsiding. Most patients with acute glomerulonephritis have edema as the first symptom. The edema is mostly seen in the face, eyelids, facial swelling and pallor, presenting the so-called nephritis face. Edema can also spread to the lower extremities, and in severe cases, pleural fluid and ascites can occur. Oedema often appears together with a decrease in urine output, which is less than usual at the beginning of the disease and can be less than 400ml per day. The edema of most patients will subside as the disease improves. 4. Elevated blood pressure Blood pressure may be mildly or moderately elevated, usually lasting 2 to 4 weeks, and will gradually normalize with increased urine output. Elevated blood pressure often occurs at the same time as edema, and can also occur after edema. When blood pressure rises suddenly, patients may also experience dizziness and headache. If the blood pressure continues to rise and does not subside, it is a precursor to chronic nephritis, indicating a more serious kidney disease. In addition to the above clinical manifestations, patients often have general discomfort, fatigue, lumbar acidity, loss of appetite, nausea and vomiting, poor spirit, some patients with uncontrolled prodromal infection, then fever can appear, the body temperature is generally around 38 ℃. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. 2, more into the high calorie, vitamin diet: acute nephritis patients should ensure an adequate daily supply of calories, and appropriate to increase the intake of vitamins. Generally, you can eat more carbohydrate food and fresh vegetables, etc. 3, the diet should be light, should not be too salty: acute nephritis with severe edema, must be strictly limited salt. In the elderly and children more can induce heart failure in the elderly and children hypertensive encephalopathy, cerebral edema. Foods with high sodium content, such as sausage, ham, pickles, squash and curd, should be prohibited. However, for patients with oliguria and edema is not obvious, it is not necessary to absolutely ban salt, just put less when cooking.
