For patients with Diabetes, if they have no symptoms of Heart Failure or
Renal Insufficiency, etc chronic complex, they should not restrict water intake.
That is because the condition of hyperglycemia can lead to osmotic diuresis,
which causes excess lose of water. If patients don't supplement enough water, it
can cause dehydration. As a result, it increases blood viscosity, leads to blood
circulation's disturbance and thrombopoiesis. Besides, it increases the risk of
Cardiac Cerebral And Vascular Diseases. Further more, dehydration can also
damage nerve fibre, which promotes diabetic neuropathy or makes diabetic
neuropathy get worse.
However, for patients with Diabetic Nephropathy, they should properly
restrict the water intake. When their renal function are at the compensatory
stage, if urine volume is normal and there are no symptoms of edema on faces or
legs, heart failure performance such as dyspnea, patients should not strictly
restrict water intake. But once patients' renal function is at the
discompensation stage and there are symptoms of edema on faces or legs, heart
failure, they should watch out and control the water intake less than 1000ml
each day. Besides, they should calculate 24 hours' urine volume and control the
intake of water less than urine volume, which is good for detumescence.
Attentions: when it is hot or patients have a fever, they can control the
water intake 700ml more than the quantity of urine volume, which supplements
water loss of breath and sweat, avoid dehydration. In a word, patients should
well control the water intake which should be consistent with the quantities of
urine volume. Moreover, the water intake includes all liquid including porridge
and soup.
