Drink water often but seldom urinate. What's going on here?

The causes of excessive water and less urine can be divided into physiological and pathological. Physiological factors are more common in sweating, resulting in less water and less urination; Physiological factors can be seen in digestive tract dehydration (frequent retching or diarrhea), renal failure, urinary tract obstruction, early shock, recessive gene dehydration (burning or tracheal intubation) or moderate and severe hypoproteinemia. All these will lead to drinking more water and urinating less.

1. Digestive tract dehydration: when nausea, vomiting and diarrhea occur, a large amount of blood is lost from the digestive system, and the amount of liquid absorbed by the human body is not enough. In this case, even drinking water will lead to less urination, which can be recovered after being completely filled with liquid;

2. Chronic renal failure: When chronic renal failure occurs in patients with severe chronic kidney disease, renal function loses the function of drainage pipe and hypokalemia occurs. After drinking water, patients may have less urination, that is, oliguria and anuria, often accompanied by edema.

3. Urinary tract obstruction: In the case of urinary tract obstruction, even if the amount of drinking water is increased, urine may not flow out of the body due to infarction, such as bilateral urinary calculi and moderate and severe prostate enlargement.

4. Early cardiac arrest: In the early stage of cardiac arrest, the blood perfusion of renal function suddenly decreases, which can cause oliguria and anuria. At this time, there is no organic disease in renal function, and drinking water but urinating less can occur.

5. Non-dominant gene dehydration: patients with fever or tracheal intubation will lose water in the respiratory system. , there will be oliguria.

6. Moderate and severe hypoproteinemia: At this time, due to the low plasma protein and low osmotic pressure, the liquid medicine drunk into the digestive tract enters the blood, and then quickly enters the serosal cavity and its subcutaneous tissue (i.e. the third space) due to the osmotic pressure. At this time, there will also be more drinking and less urine, but the systemic edema and serosal effusion will become heavier. This kind of moderate and severe hypoproteinemia is more common in three situations: nephrotic syndrome (excessive loss); Decompensated ascites due to cirrhosis (insufficient yield); Chronic active hepatitis in the middle and late stages (nutritional deficiency is more serious).
