Introduction
In general, a low hematocrit may be caused by aging, excessive water intake, living at high altitudes, malnutrition, nephritis, or other reasons. Treatment may include general measures and medication under the guidance of a physician. Maintaining a balanced diet and consuming foods rich in iron, folic acid, and other essential nutrients for blood production is beneficial for overall health.
Generally, a low hematocrit level may be caused by factors such as aging, excessive water intake, living at high altitudes, malnutrition, or nephritis. Treatment may include general management and medication under the guidance of a physician. Specific causes are analyzed as follows:
1. Aging
With advancing age, bone marrow's blood-producing function gradually declines, which may lead to a lower hematocrit level. It is important to maintain adequate nutrition and undergo regular complete blood count (CBC) tests.
2. Excessive Water Intake
Drinking too much water can dilute the blood, reducing the volume percentage of red blood cells. Maintaining normal hydration habits and balancing body fluid levels is recommended.
3. Living at High Altitude
In high-altitude environments with lower oxygen levels, the body may increase plasma volume to enhance oxygen delivery as an adaptation to hypoxia, resulting in a lower hematocrit. It is advisable to maintain healthy lifestyle habits and avoid strenuous physical activity.
4. Malnutrition
Long-term picky eating or dieting may lead to malnutrition and deficiencies in essential nutrients required for red blood cell production—such as iron, vitamin B12, and folic acid—resulting in reduced hematocrit. Symptoms such as fatigue and dizziness may occur. Under medical guidance, medications like Lysine Hydrochloride Tablets with Five Vitamins, Oral Zinc Sulfate Solution, and Compound Vitamin B Tablets may be used for treatment.
5. Nephritis
Nephritis is usually caused by insufficient fluid intake, drug abuse, or bacterial infection, and may impair kidney function, leading to decreased erythropoietin production and consequently low hematocrit. Symptoms such as edema and proteinuria may also be present. Under a doctor’s supervision, medications such as Nephritis Recovery Tablets, Prednisone Acetate Tablets, and Jinshuibao Capsules may be prescribed for treatment.
Maintaining a balanced diet and consuming foods rich in iron, folic acid, and other blood-forming nutrients is beneficial for overall health.
