The causes of drinking water without urination are complex and mainly include pre-renal, renal and post-renal factors.
Pre-renal factors mainly include reduction of effective blood volume, such as shock, hemorrhage, hepatorenal syndrome and nephrotic syndrome, etc.; decline in cardiac excretory function, cardiac insufficiency caused by various reasons, such as severe arrhythmia; renal vascular lesions, such as renal vascular stenosis or inflammation, such as nephrotic syndrome, lupus nephritis.
Renal factors mainly include glomerular lesions such as nephritis, drug-induced decline in renal function; tubular lesions such as interstitial nephritis.
Post-renal factors include mechanical urinary tract obstruction caused by various reasons such as stones, blood clots, necrotic tissues, as well as external urethral pressure such as tumors, lymphomas, prostate hypertrophy; scar contracture after ureteral surgery can also lead to drinking but not urinating.
When oliguria or anuria occurs, you should consult a doctor in time, under the guidance of the doctor for treatment, and pay attention to good daily habits and eat a light diet.
