How long does it take to recover from urinary protein 2+ is generally determined by the patient’s condition. If it is due to physiological factors, it can generally return to normal soon; if it is due to urinary tract infection, it is generally about two weeks; if it is due to kidney disease, the recovery time is relatively long and cannot be generalized. 1. Physiological factors: after strenuous exercise and consumption of high protein food, the urine protein may be elevated, and it will return to normal soon after removing the relevant factors. 2. Urinary tract infection: patients with pyelonephritis may have tubular proteinuria, most of the pyelonephritis is caused by gram-negative bacillus infection, treatment drugs include levofloxacin, amoxicillin, etc., usually about two weeks will return to normal. 3. Nephropathy: the recovery time is relatively long and varies with different pathologic types. For example, tiny lesion nephropathy, after using sufficient amount of hormone treatment, usually can return to normal soon, but easy to relapse. Membranous nephropathy patients have relatively long recovery time, as little as 3-6 months, more than a few years, and some patients can not even turn negative for life. Patients with urinary protein 2+ should go to the hospital in time and get timely treatment under the guidance of professional physicians.
