Hi, Thanks for asking. Based on your query, my opinion is as follows. 1. The serum potassium levels should be above 3.5 mmol/L to avoid drips. It should be less than 5 mmol/L always. The range is 3.5-5 mmol/L 2. Low potassium is known to myalgia, muscle cramps, abnormal heart rhythms, flaccid paralysis, constipation, etc. It needs to be corrected slowly, as increased potassium is much more dangerous. 3. Potassium blood check up and results should be complete within an hour of you giving your sample to the lab. 4. Take potassium rich food in diet like potato, banana, apricots, fish etc to improve potassium. Diuretics commonly cause hypokalemia. Look into your medications. Hope it helps. Any further queries, happy to help again.
