Low blood potassium may be caused by conditions such as decreased potassium intake, excessive potassium excretion, and transfer of extracellular potassium to intracellular.
1. Decreased potassium intake: Patients who suffer from gastrointestinal obstruction or need to fast for a long period of time after surgery may have low blood potassium, as these patients are unable to take in enough potassium from food, which will lead to the emergence of this symptom.
2. Excessive potassium excretion: patients with severe diarrhea and vomiting may lead to excessive potassium excretion from the body, which may cause low blood potassium.
3. Transfer of extracellular potassium to intracellular: for example, alkalosis, barium poisoning, etc. will lead to the transfer of extracellular potassium to intracellular, which will also lead to the emergence of hypokalemia.
If the above situation occurs, patients should seek medical treatment in time to avoid the aggravation of low potassium, which may affect the normal work of urinary system and cardiovascular system.
