Will chronic nephritis cause fainting?

Chronic nephritis is relatively common and people of any age may suffer from the disease. The main patients are middle-aged and young people, especially male patients are more than female patients. Because the disease is chronic, it meets the characteristics of many chronic diseases. The onset is relatively slow and it is less likely to be detected. This disease has many symptoms. So, will you faint if you suffer from chronic nephritis?

Proteinuria, hematuria, hypertension and edema are the basic clinical manifestations of this disease. There may be varying degrees of renal impairment. The condition may be mild or severe, prolonged, and gradually develop into chronic renal failure. Laboratory examinations mostly show mild urine abnormalities, with urine protein usually at 1 to 3 g/d. Microscopic examination of urine sediment may reveal an increase in red blood cells and visible casts. Blood pressure may be normal or slightly elevated. Renal function is normal or slightly impaired (decreased creatinine clearance or mild azotemia). This situation can last for several years or even decades. Renal function gradually deteriorates and corresponding clinical manifestations (such as anemia, increased blood pressure, etc.) appear, and uremia occurs.

If blood pressure is not well controlled, renal function will deteriorate rapidly and the prognosis will be poor. In addition, some patients have acute attacks due to infection or fatigue, or their condition rapidly worsens after taking nephrotoxic drugs. Their condition can be relieved to a certain extent after timely removal of the inducement and appropriate treatment, but they may also enter irreversible chronic renal failure. The renal function of most patients with chronic nephritis is chronically and progressively impaired. The pathological type is an important factor in determining how quickly renal function progresses (e.g. mesangial capillary glomerulonephritis progresses faster, while membranous nephropathy progresses more slowly), but it is also related to whether the treatment is reasonable.

Kidney disease can cause dizziness. When kidney disease develops to the stage of renal failure and uremia, in addition to the damage to the site of the kidney that produces erythropoietin, the affinity of hemoglobin for oxygen decreases, the utilization rate of oxygen per unit of hemoglobin increases, renal ischemia is relatively less serious, and the main stimulus for erythropoietin production decreases, resulting in a significant decrease in erythropoietin production. There are also toxins that inhibit the bone marrow. Certain toxic substances accumulated in the blood during chronic renal failure have a direct inhibitory effect on the bone marrow, leading to hematopoietic dysfunction. In addition, if patients with chronic renal failure have increased red blood cell destruction, it is also one of the causes of anemia. This is because high polyamineemia in uremia shortens the life of red blood cells and causes autolysis. In uremia, red blood cell metabolism is impaired and red blood cell fragility increases, leading to red blood cell autolysis. Microvascular lesions cause mechanical damage and destruction of red blood cells, and hypersplenism. As well as increased red blood cell loss, chronic long-term upper or lower gastrointestinal tract occult bleeding, frequent blood draws for laboratory tests or loss of residual blood in the dialyzer can aggravate the condition of patients with chronic renal failure. It may also be caused by other diseases, such as high blood pressure, diabetes, etc. Some diseases may affect the hematopoietic function and may also affect the body's absorption of nutrients, leading to malnutrition and inducing the occurrence of this phenomenon.

Hello, the kidneys can secrete erythropoietin. Chronic kidney disease causes a decrease in erythropoietin, so patients with chronic kidney disease often suffer from anemia. Common symptoms of anemia include dizziness, fatigue, palpitations, shortness of breath, loss of appetite, pale skin and mucous membranes, and flat nails. It is recommended to take medication after a detailed examination by a physician. It is recommended to go to the hospital for examination, such as routine blood tests can confirm the anemia. After diagnosis, appropriate treatment is given.

Patients with chronic nephritis should pay more attention to rest, not work too hard, keep warm, and try not to catch a cold. Pay attention to personal hygiene, take a bath frequently and prevent skin infection. Eat regularly, don’t be picky eaters, and make sure you get enough nutrition. Go to the hospital for more frequent check-ups. If you have edema and high blood pressure at the same time, don't eat too much salt.
