2) Muscle Weakness

The muscle tissue works with action potentials, and they depend on the balance between sodium and potassium on the outside and the inside of cells. The concentration of these electrolytes is fundamental to activating the muscles and triggering a contraction. Reducing the level of potassium in the blood and inside the cells would interfere with muscle signaling and compromise muscle function.
The second most common problem in patients with hypokalemia is muscle weakness, which often manifests as reduced muscle strength. Some patients drop things involuntarily, and others go as far as being unable to walk or stand up.
