Baking Soda for Acid Reflux

Author: Staff Writer

Using baking soda for acid reflux is an old folk remedy, but its value in treating heartburn has been verified by scientific fact. Baking soda, or sodium bicarbonate, is alkaline. When a small amount is mixed with water, it neutralizes refluxed stomach acid. [1] In fact, one popular effervescent antacid tablet has sodium bicarbonate as its main active ingredient. [2]

How to Use Baking Soda for Acid Reflux

According to the US National Library of Medicine, you should only use a half teaspoon of baking soda dissolved in a four-ounce glass of water when acid reflux occurs. The solution should be completely dissolved before ingesting.  You should not ingest baking soda when overly full.  It should never be administered to children.  It is important that you do not ingest more than seven ½ teaspoons in a 24-hour period-no more than three ½ teaspoons if you are older than 60.  Don't use for more than two weeks.  [3]

Baking Soda Carries Potential Side Effects

Just because something is natural does always mean it is safe for everyone.  The use of sodium bicarbonate should be supervised by a physician since it carries with it potential side effects.  This is especially true for chronic ingestion.

Drug Interaction. Sodium bicarbonate may have interactions with other drugs.

Medical Condition Considerations.  The use of sodium bicarbonate can cause problems when other health conditions exist such as appendicitis, intestinal bleeding, edema, heart disease, kidney disease, liver disease, problems with urination, or toxemia of pregnancy. [4]

Gastric Rupture. Though rare, gastric rupture has been reported as a side effect of sodium bicarbonate.  When combined with gastric acid, it can cause excess gas release, which may cause a serious problem combined with excess food or liquid intake. [5]

High Blood Pressure Precaution

Each ½ teaspoon of baking soda contains 616mg of sodium. [6] Those with high blood pressure on sodium-restricted diets should not use sodium bicarbonate as an antacid unless prescribed by a physician. [7]

Quote:  "Even if sodium is not a problem for you, using sodium bicarbonate as your regular antacid might be troublesome. Your body absorbs all the sodium bicarbonate you swallow. Take in too much and you may end up with "clinically significant metabolic alkalosis". Translation: A potentially serious imbalance in pH."

Quote:  "In general, oral and intravenous treatment with sodium bicarbonate that is given for the right reasons and in proper doses is considered safe. Concern has been raised that the same substance can be dangerous in other medical situations."
