Low specific gravity of urine can be divided into physiological and pathological cases, physiological cases include drinking a lot of water, after controlling the amount of drinking water, usually can return to normal. Pathological include uremia, interstitial nephritis, renal failure and other diseases that affect the urine concentration function, the treatment includes drug therapy, dialysis treatment, etc..
1. Physiological: patients drink too much water, urine volume increases, urine specific gravity decreases, control water consumption, review will usually return to normal.
2. Pathologic: including uremia, interstitial nephritis, renal failure and so on. Uremia refers to insufficient secretion of antidiuretic hormone (also known as central, clinical manifestations of a group of thirst and drinking, discharge of a large amount of hypotonic urine as the characteristics of the syndrome, therapeutic drugs are hydromorphone, lysine hydromorphone, ellagic acid hydromorphone, etc.).
Interstitial nephritis includes avoiding further damage to renal function, symptomatic supportive therapy and immunosuppressive therapy. Renal failure treatment is mainly aimed at delaying the progression of renal function and preventing the deterioration of renal function, etc. Progression to uremic stage should be timely renal replacement therapy.
Patients with low specific gravity of urine should go to the hospital in time, under the guidance of professional physicians to clarify the cause and timely treatment.
