Drinking more water and urinating less depends on the season in which you are in, or whether you are exercising strenuously. Drinking more water and urinating more is a normal phenomenon, but in summer or working in high temperature, sweating more, or performing strenuous exercise, or recently experiencing a lot of nausea, vomiting, abdominal pain, diarrhea and other discomfort, should reduce the amount of urine, so it depends on whether the patient’s in and out balance. If the patient drinks a lot of water and urinates little, there is obvious nausea, vomiting, chest tightness, breath-holding, swelling of eyelids and both lower extremities, definitely diseases are considered, such as heart disease, heart failure or kidney disease, nephritis, nephrotic syndrome or renal failure. Further examination of cardiac ultrasound, liver function, ion kidney function, urine routine, blood routine, urinary ultrasound and other tests can be performed to clarify the diagnosis. If it is caused by heart failure, it is recommended to drink less water, and at the same time, cardiac diuretic treatment. If it is caused by kidney disease, it is recommended to actively treat the primary disease.
