### Patient: Doctor, I have been feeling weak and tired lately. My muscles have been cramping too, especially in my legs. I would like to know what's wrong with me.
### Doctor: Based on your symptoms, it sounds like you might be suffering from hypokalemia. To confirm this, we would need to run a series of medical tests including hematologic tests, a complete blood count, kidney function tests, electrolytes panel, glucose measurement, and a radiographic imaging procedure. Intravenous fluid replacement may also be necessary if the condition is severe.
