As with any new product you introduce to your body, it is advisable to consult your doctor before switching to alkaline water. This is even more crucial if you have pre-existing medical conditions, are taking any medication, or have any health concerns. As you're probably aware, our bodies react differently to the most natural of products, and more so when there are underlying health issues, so the doctor's input is crucial. The doctor will evaluate your situation and advise you accordingly.
