Acute nephritis is commonly seen in children. Most cases of acute nephritis are preceded by a history of streptococcal infection one to three weeks before the onset. Once acute nephritis occurs, the main symptoms include the development of edema, especially swelling of the eyelids and face after waking up in the morning. Additionally, patients with acute nephritis will also experience hematuria, which can be visible or microscopic, with increased foam in the urine and a change in color, and even a decrease in urine output. Of course, patients with severe acute nephritis will also experience a significant increase in blood pressure, leading to nausea, vomiting, headaches, palpitations, chest tightness, shortness of breath, and an inability to lie flat, resulting in heart failure. Therefore, patients with acute nephritis need to undergo reasonable and standardized treatment to avoid complications.
