Nephritis in Hamsters


Nephritis is a medical condition that causes kidney inflammation. This may occur in one or both kidneys. Typically, the inflammation is brought on by a viral or bacterial infection. Nephritis may also be due to disorders of the immune system or high blood pressure. If left untreated, degeneration of the kidneys sets in, wherein normal kidney tissue is replaced by fibrous tissue. This is called nephrosis.




  • Dull and depressed appearance
  • Elevated body temperature
  • Dry coat
  • Abdominal pain
  • Severe thirst
  • Abnormally high production of urine, which may be cloudy
  • Elevated levels of protein and ammonia in the urine




In addition to bacterial or viral infection, high blood pressure in the kidneys and immune system disorders can lead to nephritis in hamsters.




After asking you several questions about the hamster's medical history and observing its clinical signs, your veterinarian will make a preliminary diagnosis. However, to differentiate from other kidney diseases, a urine sample will be analyzed. A hamster with nephritis will have elevated levels of protein and ammonia in its urine. X-rays may also reveal inflammation of the kidneys.
