Once the human body is short of potassium, normal exercise will be affected. The main symptoms of potassium deficiency in human body are tachycardia and arrhythmia, muscle weakness, numbness, irritability, nausea, vomiting, diarrhea, hypotension, insanity and psychological indifference. About the causes of potassium deficiency in human body, related knowledge about the causes of potassium deficiency in human body. The reason of potassium deficiency in human body is limb weakness, and the normal potassium level of flaccid paralysis is mainly regulated by renal urination. If the renal function is normal, the potassium intake in the diet is enough to maintain physiological needs, and the excess potassium will be excreted through sweat or urine. In addition, the body can also use some chemicals or hormones to regulate the balance of potassium. For example, eating can stimulate the secretion of insulin, which can promote the absorption of potassium by cells and prevent temporary low potassium caused by insufficient potassium in the diet. Hypokalemia will occur when the above metabolic mechanisms are abnormal, or when urination and perspiration are excessive and dietary supplement is insufficient. There are many foods with high potassium content, and yellow-green fruits have high potassium content. Because potassium plays an important role in cancer prevention, in addition to reducing sodium intake, eating more foods containing potassium will greatly reduce the probability of cancer. Fresh yellow-green vegetables and fruits, such as fresh dates, oranges, persimmons, apricots, kiwis, Rosa roxburghii, Hippophae rhamnoides, blackcurrants, etc. , rich in vitamins and essential trace elements. Citrus and bananas have the highest potassium content, so you might as well eat them often. Foods with high potassium content: corn, leek, soybean sprouts, lettuce, carp, silver carp, eel, lean pig, mutton, beef, pork loin, red dates, bananas, etc. The potassium content in food per100g is between 270 and 500mg. Foods with high potassium content: all kinds of beans, bean curd skin, lotus seeds, peanuts, mushrooms, seaweed, kelp, pickled mustard tuber, etc. The potassium content per100g of food is above1000mg. Followed by sweet potatoes, potatoes, bamboo shoots, spinach, black dates, fungus, ham, pork floss, eel and so on. The potassium content in food per100g is more than 500mg. When the serum potassium concentration is lower than 3.5 mmol/L, it is called hypokalemia, and intravenous injection is strictly prohibited. The clinical manifestation is 1. Limbs are weak and flaccid, tendon reflexes are dull or disappear, and in severe cases, it is difficult to breathe. 2. Indifference, dull eyes, lethargy and unconsciousness. 3. Nausea, vomiting, abdominal distension and intestinal paralysis. 4. Palpitation and arrhythmia. Vomiting, diarrhea, long-term use of diuretics without potassium supplementation. 2. Clinical manifestations such as fatigue, weakened tendon reflex, apathy, lethargy, abdominal distension, intestinal paralysis, palpitation and arrhythmia. 3. Serum potassium is lower than 3.5 mmol/l 4. ECG shows that T wave is low, bidirectional or inverted and U wave appears. The processing principle is 1. Active treatment leads to potassium deficiency. Return to a normal diet. 2. Supplement potassium salt. Principles of medication 1. When supplementing potassium, try to take it orally. If you can't take it orally, give it intravenously. 2. Intravenous potassium chloride, it is forbidden to push. Generally, glucose solution is added for drip.
