Many of my friends read the weibo and were unaware that low sodium salt is a life-saving salt, and it was widely spread, causing a certain range of panic. So, let’s see, in the end, low sodium salt is not a life-saving salt. As we all know, potassium is a necessary electrolyte for the human body, which is involved in intracellular metabolic activities, and the kidneys are the main detoxification organ for potassium excretion. If your potassium intake is insufficient, the kidneys will reduce the excretion of potassium; if your potassium intake is too much, then the kidneys will also excrete the excess potassium. Suffice it to say that if you are a person with normal kidney function, then hyperkalemia will almost never occur unless you eat low sodium salt as a meal. The causes of hyperkalemia are threefold: 1) simple ingestion or misuse of potassium-containing foods or drugs, such as penicillin potassium salts or transfusion of blood that has been stored for too long; 2) impaired renal excretion or ingestion of potassium in excess of your kidney’s capacity to excrete potassium; 3) importation of incompatible blood products or other causes of severe hemolysis, hypoxia, acidosis, or crush syndrome caused by trauma. extrusion syndrome caused by trauma, etc. Patients with renal failure should have a low sodium diet and should not consume low sodium salt. This is because low-sodium salt contains more potassium, kidney failure patients, especially urinary dysfunction, such as to the uremic stage of these patients, more potassium is not easy to be effectively excreted out of the body. The accumulation of potassium in the body will cause hyperkalemia, leading to arrhythmias and the risk of sudden death. If a patient with kidney failure goes to a specialist, the specialist will tell him that he cannot use low sodium salt. At the same time, we should know that the potassium in the human body mainly comes from food, and the food is mainly milk, bananas, oranges, raisins inside the most content. Therefore, for these foods, patients with kidney failure should be careful to take them. What kind of groups need attention when using low sodium salt? We generally believe that there are three special groups of people who should see a specialist and consume low sodium salt under the guidance of a specialist. 1. people with chronic kidney disease; 2. patients who are using potassium-protecting diuretics, such as those who are using spironolactone; 3. patients who have high potassium levels due to various reasons. In general, we believe that except for the three special groups mentioned above, the majority of the general population can safely use low sodium salt. At the same time, you should know that low sodium salt has very many benefits for patients with high blood pressure.
