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 dietary contraindications for patients with excessive potassium excretion from the kidneys? A, excessive potassium discharge patients should eat food: 1, eat more food containing more potassium to buckwheat, corn, sweet potatoes, soybeans and other high potassium elements. 2, eat more vegetables containing more potassium, spinach, amaranth, parsley, rape, kale, celery, onion, green garlic, lettuce, potatoes, yams, fresh peas, beans, etc. contain high potassium elements. 3, eat more seafood containing more potassium. Seaweed is rich in potassium, such as nori per 100 grams of potassium 1640 mg, is 175 times the sodium; kelp contains potassium is 22 times the sodium; lamb’s quarters contains potassium is 3.1 times the sodium. Therefore, nori soup, nori steamed fish, nori meatballs, cold kelp shreds, kelp stew, etc. are the best summer potassium dishes. 4.Eat more fruits with high potassium content, such as: banana, guava, tomato, willow, peach, etc. Second, the best food not to eat for patients with excessive potassium discharge: 1, try to eat less spicy, stimulating food. For example: onion, pepper, chili, pepper, mustard, fennel. 2, avoid eating fried, greasy food. Such as doughnuts, cream, butter, chocolate, etc. These foods help dampness and increase the heat, which will increase the secretion of leucorrhea, which is not conducive to the treatment of the disease. 3, quit smoking and alcohol, coffee and other excitatory drinks.
