It should have, although may be not by much
Hello ma'am and welcome.
Thank you for writing in.
Well the potassium syrup and high potassium diet should have contributed in raising your serum potassium levels. Your level (i.e. 2.7-3.1) is not far from the lower limit of normal, and should be attainable soon.
I am sure your potassium levels would have gone up by now, but the levels do not increase rapidly, so being optimistic would be expecting a level of 3.5, hoping this is the case.
Wishing you all the luck you need and more. Please feel free to write back to me for any further clarifications, I would be more than happy to help you.
