Low-grade fever generally does not cause uremia. Uremia is a clinical syndrome characterized by decreased glomerular filtration rate, metabolic acidosis, and water-electrolyte imbalance. Low-grade fever usually refers to a body temperature of 37.3-38°C or above 38°C lasting for more than 3 days. Uremia is commonly seen in chronic glomerulonephritis, diabetic nephropathy, hypertensive nephropathy, and other diseases, and is generally unrelated to infection.
1. Chronic glomerulonephritis: It is mostly developed from primary glomerular diseases with different causes, and the onset patterns vary. Clinical manifestations include proteinuria, hematuria, edema, hypertension, and other symptoms. Chronic glomerulonephritis can gradually develop into uremia, or acute exacerbation of chronic glomerulonephritis, and the development of recurrent acute glomerulonephritis can also lead to uremia.
2. Diabetic nephropathy: It is a kidney disease caused by diabetes. Diabetes generally has a concealed onset with no clinical manifestations in the early stage. As the disease progresses, diabetic nephropathy may occur, causing proteinuria, edema, and other symptoms, but generally does not lead to uremia.
3. Hypertensive nephropathy: It is a kidney disease characterized by progressive hypertension. The onset is slow, and there are no obvious symptoms in the early stage. A few patients may experience fatigue, dizziness, and other symptoms. As the disease progresses, it can lead to fundus hemorrhage, exudation, vision loss, and even uremia.
4. Other diseases: For example, systemic lupus erythematosus, which is an autoimmune disease, can cause glomerular damage when involving the kidneys, leading to lupus nephritis, proteinuria, hematuria, and other conditions, but does not cause uremia.
If you experience low-grade fever, you should promptly visit a hospital for relevant examinations. After a clear diagnosis, targeted treatment should be carried out under the guidance of a professional doctor to avoid delaying the condition. In daily life, you should pay attention to rest, avoid fatigue, and heavy physical labor.
