What could be the reason for low potassium levels despite medication?

Question

Hi doctor,

Repeated blood tests have shown low potassium levels in my blood for several months, from 3.1 to 3.3 mmol/L. The doctor prescribed potassium chloride tablets. When that did not help, he increased the dosage. That also did not help, so he increased the dosage again. Still, there was no improvement. Urine tests showed a normal level of potassium in the urine, so that is not draining the potassium. The doctor says something must be draining the potassium from my blood, but he is stumped as to what might be causing it. This started about five months ago when my blood oxygen levels decreased. My medicines include Amlodipine-benazepril, Lovastatin, Atenolol, and Metformin Any ideas on what might be causing my problem?

Thank you.

Hi,

Thank you for stopping by!

I am here to provide expert opinion on your medical issues.

I am very sorry about your medical condition. Regarding your symptom of a persistent low level of potassium despite increasing medications, I propose you have developed a subacute myopathy. Do you have any history of generalized muscle weakness or pains, fatigue, or malaise? I suggest doing an EMG (electromyography) test and reverting with the result. I suggest you take tablet Folic acid 5 mg daily. Consult your doctor and take the medication accordingly. Eat a lot of fruits and vegetables regularly.

I hope this information will help you. Please revert in case of further queries.

Thank you.
