Tubulointerstitial Nephritis
Symptoms of Tubulointerstitial Nephritis
Some people have few or no symptoms. When symptoms develop, they are highly variable and may develop suddenly or gradually. When tubulointerstitial nephritis develops suddenly, the amount of urine produced may be normal or less than normal. Sometimes the amount of urine produced is excessive and people urinate more frequently and waken during the night to urinate (nocturia). If the cause is pyelonephritis, symptoms may include fever, painful urination, and pain in the lower back or side (flank). If the cause is an allergic reaction, symptoms may include fever and a rash. When tubulointerstitial nephritis develops gradually and progressively worsens, the first symptoms to appear are those of Overview of Kidney Failure such as itchiness, fatigue, decreased appetite, nausea, vomiting, and difficulty breathing. Blood pressure is normal or only slightly above normal in the early stages of the disease. The amount of urine produced may be greater than normal.
