Blood potassium on the test sheet is normal, why did the doctor still prescribe potassium supplements?

Potassium chloride, , potassium mendeanate and magnesium mendynine are commonly used drugs in the department of heart medicine, I believe many patients and friends are familiar with.
at the same time, many patients and their families will be wondering, "The blood potassium on the test sheet clearly did not decrease, why did the doctor still give me potassium supplements?" "To answer this question, let's talk about potassium filling."
blood potassium refers to the amount of potassium in the blood, the normal reference value of blood potassium is 3.5 to 5.3mmol/L (different laboratories may have a little up and down fluctuations).
potassium is an important ion to maintain cell physiological activity and plays an important role in maintaining the body's normal osmosis pressure and acid-base balance, participating in sugar and protein metabolism, and ensuring the normal function of nerve muscles.
potassium ions are particularly important for myocardial cells, and high or low blood potassium can induce arrhythmic disorders, which can worsen the patient's condition.
mainly from food, more than 90% of the potassium in food will be absorbed in the intestines in a short period of time, 90% of the potassium absorbed into the blood will be excreted from the kidneys within 4h.
blood potassium control at 4.0-5.0mmol/l is ideal for patients with heart failure, myocardial infarction, and roomic arrhythmic disorder.
But many cardiovascular patients due to dental diseases, gastrointestinal bruising, bloating and other reasons, eat less, poor intestinal absorption, resulting in insufficient intake of potassium in the blood, at the same time, patients take certain drugs, such as diuretics, will increase the discharge of potassium.
, on the one hand, the amount of potassium entering the body is insufficient, on the other hand, the amount of potassium excreted through urine increased, the two sides of the joint effect, patients are very prone to low potassiumemia.
for this part of the patient, the doctor will prescribe potassium supplements.
if the blood potassium is less than 3.5mmol/l, you will need to take potassium chloride slow release tablets or potassiumhydrate, supplemented by potassium hypothionate magnesium.
for those with blood potassium exceeding 3.5mmol/l but not reaching 4.0mmol/l, the potassium supplement strength can be reduced appropriately, and some patients can use potassium-attain alone.
magnesium ions are a "good partner" for potassium ions in the body.
combined potassium and magnesium ions, which have the effect of co-resisting arrhythmic disorder, and can reduce the occurrence of sudden death and other events.
, magnesium supplementation can help improve the efficacy of potassium supplementation and promote the internal and external balance of potassium ion cells.
The clinically commonly used potassium chloride and potassium ate are drugs to supplement potassium ions, while potassium mentaminate magnesium is currently the only oral drug that can supplement potassium and magnesium at the same time, with less gastrointestinal irritation and good patient tolerance.
Here, I believe the patient's friends can understand why the blood potassium at about 3.6mmol/l, the test sheet clearly does not have a downward arrow, and the doctor will still give you a prescription potassium supplement.
But finally, but also to remind the vast number of patients friends, blood potassium is not the higher the better, high blood potassium is also harmful, so, should follow the doctor's instructions, regularly to the hospital blood to check blood potassium levels, and according to the results of the examination, adjust the treatment plan.
believe that with the joint efforts of you and your doctor, your blood potassium will be well managed!
