Full Answer

Symptoms of low potassium include constipation, fatigue, muscle weakness, tingling and numbness, states MedlinePlus. Low potassium also affects the heart by causing abnormal heart rhythms or palpitations. If the potassium levels continue to drop, the heart may slow or stop completely.

Oral or IV potassium raises the levels in the bloodstream back to a normal range, notes MedlinePlus.

Avocados, bananas, lean beef, baked potatoes and salmon are a few foods that are high in potassium.
