There are two main types of urine redness, one is caused by too many red blood cells in the urine and the other is caused by elevated pigment in the urine. The elevated pigment is often caused by two conditions, one is caused by the consumption of certain drugs and the other is caused by the consumption of certain foods. High protein in urine is mainly seen in three conditions: 1. caused by tumors. 2. inflammation of the urinary tract can also cause elevated protein. 3. nephritis can also cause elevated protein. Differentiation: 1, urinary tract tumors, often urine routine examination will find significantly elevated red blood cells in the urine, along with elevated protein. Often the patient has no obvious symptoms, i.e. painless hematuria, mostly in elderly patients. 2. nephritis, mostly in young people and even children. Patients often have red urine, and proteinuria and hematuria are seen in routine urine tests. Patients do not have obvious lower urinary tract irritation symptoms, such as urinary frequency and urgency, painful urination, lower abdominal cramping and discomfort, etc. Patients may have a history of acute fever and upper respiratory tract infection before the onset of the disease. 3, urinary tract infection, urinary tract infection patients will be found in the urine routine examination of urine red, elevated protein in the urine. At the same time, patients are accompanied by urinary frequency, urinary urgency, lumbar pain or lower abdominal cramping discomfort, etc. This situation requires anti-infection and other treatments.
