Watermelon is a food that is very rich in potassium. Fresh vegetables and fruits contain more potassium, you can eat more bananas, oranges, apricots, strawberries, grapefruit, grapes and other fruits as appropriate; vegetables such as bok choy, celery, onions, potatoes, beans, garlic, etc. are also rich in potassium; mung beans, adzuki beans, fava beans, black beans, lentils and kelp, nori, yellow fish, chicken, milk, cornmeal, buckwheat noodles, sunflower seeds also contain a certain amount of potassium. Drinking more tea in summer is also very beneficial, because tea is rich in potassium. Drinking more tea can not only kill the heat, but also replenish potassium.
What is hypokalemia
A serum potassium concentration below 3.5 mmol/L is called hypokalemia.
What causes hypokalemia
Hypokalemia is most often caused by long-term fasting or less food, insufficient intake of potassium salts; massive vomiting, diarrhea and long-term application of diuretics such as tachyphylaxis that cause excessive excretion of potassium. The clinical manifestations are mainly neurological and muscular dysfunction, and the more potassium is lost, the faster it is or the higher the concentration of Na+ and Ca+, the more obvious the symptoms are. When replenishing potassium intravenously, the urine volume must be above 30ml/hour, do not give too fast or too much, and intravenous pushing is strictly prohibited.
What are the symptoms of hypokalemia?
1. Weakness of the limbs, flaccid paralysis, sluggish or absent tendon reflexes, or respiratory difficulties in severe cases.
2, apathy, dull gaze, drowsiness, confusion.
3.Nausea, vomiting, abdominal distension, intestinal paralysis.
4, Palpitations, arrhythmia.
What tests are needed for hypokalemia
1.Serum potassium is lower than 3.5mmol/L.
2.Electrocardiogram shows low T wave, bidirectional or inverted and the presence of U wave.
How to treat
1.Actively treat the primary disease causing K+ deficiency and resume normal diet.
2.Replenish potassium salt.
(1) When replenishing potassium, try to take it orally if you can, or intravenously if you cannot.
(2) Intravenous potassium chloride supplementation is strictly forbidden to be pushed. Generally, it should be added to glucose solution for drip injection, and the concentration should not exceed 3%, and the drip rate should not exceed 80 drops per minute; the total amount of drip should not exceed 6g-8g per 24 hours.
(3) When accompanied by acidosis, potassium bicarbonate can be used instead.
(4) For those with hepatic impairment, potassium glutamate may be used instead.
(5) When heart involvement is obvious or accompanied by Mg deficiency, potassium magnesium L-menthate can be used.
