How can i quickly increase my potassium level? levels were at 2.9 yesterday with no symptoms. tonight i my heart has an extra beat.

Low potassium: Low potassium can be a life threatening issue! If you are feeling chest pain or extra beats, it may be worth going to the ER or contacting your family doctor. Otherwise, potassium can be elevated through diet and potassium supplements. However its very important to find out why the level is low. Medicines can do it (diuretics) as can other illnesses (vomiting, diarrhea). So get it checked!
