Sodium bicarbonate is used to treat stomach disorders, acidosis and sodium deficiency. Okay, laymen’s terms. Sodium Bicarbonate is what Pepto Bismal is made of, and Tums. When you’ve gotten a terrible stomach ache accompanied by gas, you take Tums or Pepto Bismal, right? Well, yu’re taking Socium bicarbonate. It’s great every once in a while, but it also has a lot of salt in it, so using it too often is going to raise your blood pressure, so only use it when necessary.
