Degree understand your concerns went through your details. Hypokalemia also hypopotassemia or hypopotassaemia, refers to the condition in which the concentration of potassium in the blood is low. The most obvious cause is insufficient consumption of potassium (that is, a low-potassium diet) or starvation. In your case, your case is mild Hypokalemia and can be treated with potassium rich diet and supplements. Your doctors will advise you accordingly. For the time being do not worry. You are alright.
