Sodium bicarbonate is a simple and effective natural remedy that has been used for a long time to combat heartburn, gastric reflux, and indigestion. Easy to obtain, inexpensive, and quick-acting, this alkaline compound neutralizes excess gastric acid, providing rapid relief. However, to benefit from its effects without risks, it must be used correctly.
How Does Sodium Bicarbonate Work in the Stomach?
Sodium bicarbonate has an alkaline pH (approximately 8.3) and, when ingested, chemically reacts with hydrochloric acid in the stomach (HCl), forming sodium chloride (salt), water, and carbon dioxide (gas). This reaction helps reduce acidity and soothes the sensation of burning or gastric discomfort.
How to Use Sodium Bicarbonate for the Stomach
Recommended dosage:
-
Adults: 1-2 teaspoons of food-grade sodium bicarbonate dissolved in a glass (200 ml) of plain water.
-
Drink slowly, on a full stomach, at least 1-2 hours after a meal.
-
It can be repeated a maximum of 2 times a day, but not more than 7 consecutive days.
Important: Bicarbonate should not be consumed in large doses or frequently, as it can lead to metabolic alkalosis and electrolyte imbalance.
Internal Benefits for the Stomach (Explained in Detail)
-
Rapid relief from heartburn: by directly neutralizing gastric acid, it reduces irritation of the esophageal mucosa.
-
Soothes gastroesophageal reflux: temporarily, by reducing acidity, it alleviates the burning sensation in the chest.
-
Aids in difficult digestion and bloating: in cases of an overly acidic stomach, it balances pH and reduces abdominal discomfort.
-
May reduce nausea caused by excessive gastric acid: especially after heavy meals.
Contraindications and Precautions
Bicarbonate is not a suitable remedy for everyone. Here are situations when it should be avoided or used with caution:
-
High blood pressure: contains sodium, which can increase blood pressure.
-
Kidney problems: sodium elimination may be affected.
-
Pregnancy and breastfeeding: only with a doctor’s recommendation.
-
Heart conditions: regular sodium consumption can overstrain the cardiovascular system.
-
Drug interactions: may reduce the absorption of certain medications (antibiotics, antifungals, iron supplements, etc.).
Not recommended for children under 12 years without medical advice.
What Do Studies Say?
A study published in Journal of Clinical Pharmacology (2018) showed that sodium bicarbonate has a rapid effect in neutralizing gastric acid, but is not recommended for regular use due to the risk of hypernatremia and acid-base imbalance.
Research from BMJ Open Gastroenterology (2020) compared the effectiveness of bicarbonate with other commercial antacids and concluded that effectiveness is similar, but the duration of action is shorter, and the risk of adverse effects increases with daily use.
