In summer, many friends will have dizziness, nausea, fatigue, loss of appetite and other symptoms, and most people will treat it as heatstroke. However, this may be "fake heatstroke" and the real reason is lack of potassium!

potassium is an indispensable trace element to maintain life. Serum potassium < 3.5 mmol/L is called hypokalemia, which can be divided into three categories: mild hypokalemia of 3. ~ 3.5 mmol/L; Moderately low potassium 2.5 ~ 3. mmol/L; Severe hypokalemia < 2.5 mmol/L. The role of potassium in human body

Potassium plays an important role in regulating the water balance of human body, protecting myocardial function, stabilizing blood pressure, maintaining acid-base balance, participating in metabolism, maintaining the normal function of neuromuscular, etc. Once the human body lacks potassium, the normal function of human body will be affected, and even lead to death in severe cases. Five symptoms suggest potassium deficiency

1. Dizziness and fatigue < P > Potassium deficiency often causes some nervous system symptoms, such as dizziness, fatigue, drowsiness, unconsciousness and abnormal sensation.

2. Arrhythmia

After potassium deficiency, the myocardium is affected, and the normal regular beating of the myocardium is not guaranteed, and in severe cases, cardiac arrest occurs.

3. Anorexia and nausea

Long-term potassium deficiency can slow down the intestinal peristalsis of patients, leading to problems such as loss of appetite, nausea, abdominal distension, vomiting and constipation.

4. polyuria and thirst

potassium deficiency will affect the urinary system, and patients often have symptoms such as urine dilution, polyuria and thirst.

5. Limb weakness and numbness

Potassium can maintain the normal function of muscles. If potassium is lacking, it will affect the muscle system. The common symptoms are limb muscle weakness and numbness, dyspnea, breathlessness, and weak breathing. What are the reasons for potassium deficiency in summer?

In summer, people often have poor appetite and eat less, resulting in insufficient nutrition, which in turn leads to insufficient intake of electrolytes such as potassium, sodium, calcium and chlorine.

Secondly, it is easy to sweat in summer, which is easy to cause potassium loss.

In addition, gastrointestinal diseases, such as gastrointestinal dysfunction, diarrhea and vomiting, are prone to occur in summer, which will make the body lose potassium ions.

Finally, some diseases and drugs themselves may cause low potassium. How to supplement potassium?

Potassium deficiency naturally requires potassium supplementation. The recommended standard in China is 2 grams per day for healthy adults, and the standard for preventing chronic diseases is 3.6 grams. Who recommends 3.5 grams per day, and the United States recommends a higher amount, 4.7 grams per day. Investigation shows that the potassium intake of China residents is insufficient, and the safest way to supplement potassium is to eat.

1. Vegetables

Spinach, water spinach, amaranth, laver, etc. Among them, every 1g of laver contains 1,796 mg of potassium, and every 1g of amaranth contains 27 mg of potassium. Eating a catty of fresh green leafy vegetables every day can meet half of the potassium requirement. Moreover, these dark green vegetables are also rich in carotene, riboflavin, vitamin C and various phytochemicals, and their nutritional value is also high.

2. Potatoes and beans

Soybeans, black beans, kidney beans and other beans, as well as taro and potatoes, all have high potassium content, all exceeding 1 mg /1 g, 1 g of taro containing 378 mg and 1 g of potato containing 342 mg of potassium. In addition, some bean products, such as bean skin and dried tofu, are rich in potassium.

3. Fruits

An apple contains about 238 mg, an orange contains about 38 mg, and a banana contains about 256 mg. In addition, dates, strawberries, cherries, kiwis, peaches, coconuts, etc. all have good potassium supplementation effects.

4. Staple food

There are also foods rich in potassium in staple food, and millet is one of them, with 3 mg of potassium per 1 grams.

In addition, Agrocybe aegerita, Lentinus edodes, Coprinus comatus and other mushrooms, longan, pine nuts and other nuts, most fish and meat are rich in potassium, which can be eaten in moderation.

However, if dietary potassium supplementation doesn't work, it depends on whether you are taking drugs that cause low potassium, and consult your doctor whether you can choose other drugs instead. If you can't, you can take potassium supplementation orally or infusion. When repeated potassium supplementation is ineffective, it is necessary to check the causes of potassium deficiency and eliminate disease factors.
