Hypertension and IgA nephropathy can occur at the same time, and having IgA nephropathy also tends to lead to hypertension, there is no conflict for treatment, mainly for the treatment of IgA nephropathy. For the treatment of IgA nephropathy, first of all, you need to decide the treatment plan according to the amount of urine protein quantification and renal pathology, you can first apply ACEI or ARB drugs, such as Irbesartan, Valsartan, Benazepril and so on. These drugs have the effects of protecting kidney, controlling blood pressure and reducing urine protein at the same time, so they are very suitable treatment goals to make blood pressure less than 130/80mmHg and 24-hour urine protein quantification less than 0.5g. If after 3-6 months of these treatments, urine protein quantification is still greater than 1g, then it is necessary to add hormone therapy. The more common treatment plan is to take 40mg of hormone once a day, then reduce the dosage regularly and observe the change of urine protein quantification. Diet is low in salt, low in fat and high in protein, which is also very helpful to control blood pressure and reduce the burden on the kidneys.
