I. Basic Water Intake
For patients without complications, daily water intake is part of basic health management.It is recommended to drink plain water, light tea, or mineral water, with a total daily volume of 1600–2000 ml.Additional fluid replacement may be needed during hot weather or after heavy physical activity.
For patients with cardiac or renal insufficiency, water intake must be strictly controlled, and the specific amount should follow the doctor’s advice.
II. Adjustment in Special Situations
Individual conditions vary, so water intake may need adjustment.Especially when blood glucose is poorly controlled, osmotic diuresis may cause polyuria, requiring more fluid intake — usually 2000–2500 ml or even more.
If you experience severe, unrelieved thirst (water intake over 3000 ml still cannot quench thirst), or are at risk of hyperosmolar state or ketosis, seek medical help immediately, as these may be signs of acute complications.
III. Ways to Drink Water
Proper drinking habits are equally important.Drink small amounts frequently, about 200 ml each time, and avoid large volumes at once.Drinking moderately 1 hour before bedtime helps reduce blood viscosity at night.
Do not wait until you feel thirsty. Develop a habit of drinking water regularly, especially in summer or during exercise, and hydrate in advance.
IV. Precautions
In addition to direct water intake, water from foods such as fruits and vegetables should also be counted toward your total daily fluid intake.
For patients with diabetic kidney disease, urine output and edema should be monitored regularly to adjust water intake accordingly.If you have other conditions such as hypertension or digestive disorders, personalized fluid adjustment under the guidance of a clinician is recommended.
