What is the reason for low blood crystal permeability

Low blood crystal osmotic pressure may be caused by factors such as excessive water intake, malnutrition, chronic kidney disease, syndrome of abnormal secretion of antidiuretic hormone, and adrenal cortex dysfunction.

1. Excessive water intake:

Drinking a large amount of water or intravenous infusion in a short period of time can lead to blood dilution, a decrease in electrolyte concentration in plasma, and a decrease in crystal osmotic pressure. This situation is common in patients with psychogenic restlessness or improper fluid replacement therapy, and can usually be corrected by limiting fluid intake.

2. Malnutrition:

When long-term protein and electrolyte intake is insufficient, plasma albumin and crystalline substances such as sodium and chloride decrease. Severe malnutrition patients may develop hypoalbuminemia combined with hyponatremia, which needs to be improved through progressive nutritional supplementation while monitoring electrolyte balance.

3. Chronic kidney disease:

When renal dysfunction occurs, urinary concentration is impaired, sodium ion reabsorption is reduced, and protein is lost from urine. Patients often present with persistent hyponatremia accompanied by edema, requiring restriction of water intake and use of diuretics. In severe cases, dialysis treatment is necessary.

4. Abnormality of antidiuretic hormone:

Syndrome of abnormal antidiuretic hormone secretion SIADH will lead to kidney drainage disorder, water retention and dilution of blood sodium. Commonly seen in lung diseases, central nervous system disorders, or certain drug effects, treatment requires fluid restriction and the use of diuretics as appropriate.

5. Adrenal dysfunction:

When there is a deficiency of adrenal cortex hormones, there may be a decrease in tubular sodium reabsorption, which may be accompanied by insufficient aldosterone secretion. Patients may experience symptoms such as fatigue and hypotension, requiring hormone replacement therapy and strict monitoring of blood sodium levels.

It is necessary to maintain a balanced diet in daily life, ensure that the daily protein intake is not less than 1 gram per kilogram of body weight, and control the daily water intake within the range of 1500-2000 milliliters. Patients with hypertension or kidney disease should regularly check blood sodium, blood urea nitrogen and other indicators to avoid excessive drinking after vigorous exercise. When experiencing persistent symptoms of low sodium such as nausea and drowsiness, it is necessary to seek medical attention in a timely manner. Do not take salt tablets on your own to correct it, in order to prevent the induction of central nervous system damage.
