The Dangers of Sodium Bicarbonate for Your Heart
Drinking baking soda, scientifically known as sodium bicarbonate, has gained popularity as a purported health tonic or remedy for indigestion. While it can neutralize stomach acid, its high sodium content and ability to disrupt the body's delicate chemical balance make it a significant risk factor for cardiovascular complications, rather than a benefit.
The Direct Link Between High Sodium and Cardiovascular Risk
Excessive sodium intake is a well-established risk factor for high blood pressure (hypertension) and heart disease. A single teaspoon of baking soda contains approximately 1,260 mg of sodium, far exceeding the 1,500 mg daily limit recommended by the American Heart Association (AHA) for many people, especially those with or at risk for hypertension. Consuming this much sodium at once can cause a sharp, dangerous spike in blood pressure, putting a strain on the heart and blood vessels. For individuals already dealing with heart disease or hypertension, this risk is especially pronounced.
Electrolyte Imbalances and Arrhythmias
In addition to the sodium load, excessive baking soda can cause a dangerous imbalance of electrolytes in the body. When a large amount of bicarbonate is ingested, the body attempts to compensate, which can lead to a state of metabolic alkalosis, where the blood's pH becomes too alkaline. This, in turn, can cause a severe drop in potassium levels, a condition known as hypokalemia.
Electrolytes like potassium are crucial for regulating heart rhythm. A sudden shift can lead to serious cardiac effects, including:
- Ventricular arrhythmias: Irregular heartbeats that can be life-threatening.
- Decreased myocardial contractility: A blunted response of the heart muscle, making it less effective at pumping blood.
- QT interval prolongation: An electrical abnormality that can cause sudden cardiac death.
Acute Overdose Risks
While most risks are associated with regular, improper use, an acute overdose can have immediate and disastrous consequences. Case studies have reported incidents of severe baking soda intoxication leading to cardiac arrest. Beyond heart-specific issues, large doses can also cause stomach rupture due to the rapid release of gas when sodium bicarbonate reacts with stomach acid. This is a rare but extremely serious complication.
Who is Most at Risk?
Certain populations are particularly vulnerable to the dangers of drinking baking soda:
- Individuals with heart conditions: Those with pre-existing heart failure, arrhythmias, or hypertension are at the highest risk.
- People with kidney disease: Impaired kidney function can prevent the body from properly processing the high sodium and bicarbonate load, increasing the risk of metabolic alkalosis.
- Pregnant women: Baking soda can cause the body to retain fluids, which can be harmful during pregnancy.
- Children: Children's smaller bodies are more susceptible to toxic effects from concentrated substances like baking soda.
Safer Alternatives for Heartburn Relief
For those seeking relief from heartburn, it is crucial to use safer, medically approved alternatives instead of relying on a risky home remedy. Over-the-counter (OTC) antacids are specifically formulated to be safe and effective, without the excessive sodium load.
| Feature | Baking Soda (Homemade Remedy) | OTC Antacids (e.g., Tums, Rolaids) |
|---|---|---|
| Sodium Content | Extremely high (approx. 1,260 mg/tsp) | Generally low or sodium-free |
| Safety Profile | Dangerous; can cause metabolic alkalosis and heart issues | Medically formulated for safety; low risk of side effects when used correctly |
| Active Ingredients | Sodium Bicarbonate | Calcium Carbonate, Magnesium Hydroxide, Aluminum Hydroxide, etc. |
| Long-Term Use | Not recommended; carries significant risks | Generally safe for short-term use; follow label instructions |
| Medical Supervision | Crucial; always consult a doctor | Often available over-the-counter for occasional use; consult a doctor for chronic symptoms |
What to Do If You Experience Symptoms
If you have consumed baking soda and experience symptoms like severe chest pain, an irregular heartbeat, confusion, muscle twitching, or difficulty breathing, seek immediate medical attention. In the US, you should call Poison Control at 1-800-222-1222. The risks of self-treating with baking soda far outweigh any perceived benefits.
The Final Verdict on a Dangerous Home Remedy
When it comes to cardiovascular health, drinking baking soda is a dangerous practice that should be avoided. The evidence is clear that its high sodium content can lead to a host of cardiac problems, from elevated blood pressure to life-threatening arrhythmias. The temporary relief it may offer for indigestion is not worth the serious health risks. Always opt for medically endorsed treatments and consult a healthcare provider before trying any new remedy, especially if you have pre-existing health conditions.

Conclusion
In summary, the notion that drinking baking soda is good for your heart is a dangerous myth. It is a source of extremely high sodium that can disrupt the body's electrolyte balance, leading to increased blood pressure and potential cardiac emergencies. Instead of relying on this unproven and risky home remedy, turn to medically approved antacids for short-term relief or consult a healthcare professional for persistent symptoms. Prioritizing proven, safe methods for wellness is always the best approach for protecting your heart and overall health.
