Heartburn is a common condition during pregnancy, but antacids are not always the solution to controlling the acid buildup. Some antacids contain ingredients or chemicals that can cross the placenta and affect the baby, while others may cause issues for the mother. Understand what antacids are safe to take during pregnancy or try natural remedies for preventing heartburn to provide the best protection for baby and mother.
Heartburn Causes
Heartburn is caused when the valve between the esophagus and stomach is unable to stay closed, allowing stomach acids to flow from the stomach back up into the esophagus. The hormone progesterone produced during pregnancy can cause the valve to relax, letting this occur. The stomach acids irritate the lining of the esophagus and cause you to experience the sensation known as heartburn. During the third trimester, there is more pressure on the stomach from the growing uterus, making heartburn more common during this time.
Recommended Antacids
Calcium carbonate chewable antacids are the first type of antacid product recommended when treating pregnancy heartburn. They generally are regarded as safe and are not known to cross the placenta. Also, a liquid or tablet form antacid containing magnesium hydroxide or magnesium oxide is regarded as safe and not thought to cross the placenta. Drink as little water as possible when swallowing antacid tablets since swallowing liquid causes your stomach to produce digestive juices, including acids. Chewable and liquid products work more quickly than tablets.
Antacids to Avoid
Antacids containing any form of aluminum can cause constipation and, if taken in large doses, result in toxicity. Products containing aspirin are not recommended as safe for pregnant women. Other names for aspirin include salicylate and acetylsalicylic acid. Ingesting aspirin during pregnancy can result in miscarriage during early pregnancy; it also may cause placental abruption or other medical issues for the developing baby. Baking soda and antacids that contain baking soda, also called sodium citrate, are not suitable for pregnant women because baking soda is high in sodium and can cause water retention.
Preventing Heartburn
Eat five to six small meals spaced throughout the day to prevent heartburn. Skip eating spicy or greasy foods and don't lie down for at least one hour after eating to prevent experiencing heartburn. If you do feel heartburn coming on, eat some yogurt or drink a glass of milk to neutralize the acids.
