Dear user,

I really understand your concern.

Normally, blood potassium level is 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life-threatening and requires urgent medical attention.

Based on your blood test, you have had some readings: 3.6, 3.3, 3.4, all these are quite normal, so there' nothing to worry about.

Also I would say that values range varies from one to another lab and also from the use of potassium med and diet that you follow. You may have had low potassium level, for that I think the doctor prescribed potassium pills.

Causes for this in patients with diabetes are chronic kidney disease, diabetic ketoacidosis, frequent urination. Some other common causes are diarrhea, exessive sweating and vomiting.

Hope my answer was helpful for you.
Best wishes!
