Whether nephritis occult blood 3+ is serious or not cannot be generalized, it needs to be judged according to the specific condition. Occult blood 3+ means that the red blood cells in urine have increased. If there is no abnormality in blood pressure and urine protein, it is generally not serious; if there is abnormality in blood pressure and urine protein, it is more serious.
If patients with nephritis only have occult blood 3+ and no abnormality in blood pressure and urine protein, it suggests that the condition of renal function is more stable, and through active treatment, the hematuria will usually disappear, and the damage of renal function can be prevented, which is generally not serious.
However, if blood pressure rises and urine protein increases, when treatment is not appropriate, the condition will further develop into a chronic disease, and may even eventually develop into renal failure, which is a serious condition.
Nephritis patients should pay attention to the principle of low-salt, low-fat and high-quality protein diet in their daily life to avoid increasing the burden on kidneys. Meanwhile, they should actively cooperate with doctors to control the disease development.
