Excessive potassium excretion is commonly associated with long-term use of diuretics or excessive dosage. Long-term use of thiazide diuretics may lead to water and electrolyte disturbances, resulting in hyponatremia, hypochlorhydria and hypokalemia. The kidneys are extremely capable of excreting potassium quickly, and about 90% of ingested potassium is excreted in the urine within 4 hours. The excretion of potassium is characterized by more excretion, less excretion and no excretion, i.e. the kidney’s ability to conserve potassium is lower than its ability to conserve sodium. What are the causes of excessive potassium excretion by the kidneys? 1. Electrolyte imbalance During the treatment of leukemia, there is often excessive potassium excretion due to excessive destruction of leukemia cells or due to chemotherapy drug-related kidney damage. Also, chemotherapy causes poor appetite and digestive system dysfunction, resulting in low blood potassium due to insufficient incorporation. Or low calcium due to increased phosphorus release due to leukemia cell destruction, etc. Treatment: Pay attention to electrolyte concentrations such as potassium, calcium and sodium during treatment and replenish them in a timely manner. 2, gastrointestinal failure As the chemotherapy drugs and radiotherapy means in the treatment of leukemia affect the gastrointestinal function, which leads to gastrointestinal failure, the nutritional supplementation of patients becomes a prominent problem, and the nutritional deficiency can lead to pneumonia, enteritis and other complications. Treatment: The current use of subclavian vein cannulation into the superior vena cava for high nutritional infusion only partially solves the problem. Its fundamental and long-lasting method needs to choose Chinese herbal medicine protector of life, which is the essence component of ginseng and can increase the patient’s specific and non-specific immune function, enhance the patient’s constitution, improve the ability to resist disease and reduce the chance of infection. It is not only a strong agent for tonic treatment, but also a protective agent for the function of many organ tissues, including gastrointestinal, and its pharmacological activity has received wide attention and application.
