Patient's question:
Doctor, I couldn't sleep last night, so I started playing on my phone and scrolling through WeChat Moments. I noticed that a friend of mine has nephritis. I want to know what nephritis is, how serious it is, and at what age group it is more likely to recur. What symptoms might nephritis cause if it reappears?Doctor's answer:
Nephritis refers to the decline in kidney function, most commonly caused by autoimmune factors, leading to the deterioration of physiological kidney function, impaired excretion of metabolites, and disruption of water, electrolyte, and acid-base balance. The main symptoms include edema, high blood pressure, hematuria, or urinary issues. Nephritis can be classified into several types, with some more prevalent in children, others in young adults, and some more common in the elderly. Based on the location of inflammation, it is further divided into glomerulonephritis and interstitial nephritis. Glomerulonephritis typically presents with more severe symptoms.
