What Happens After You Take Baking Soda?
Baking Soda and the Body: What to Expect
People have reached for baking soda for decades to ease heartburn, soothe an upset stomach, or even help athletic performance. As an antacid, it neutralizes stomach acid pretty well. Still, questions linger about how long it sticks around in the system—and how safe it actually is.
How Baking Soda Moves Through You
Baking soda, or sodium bicarbonate, works fast. Swallow a teaspoon mixed in water and within minutes, it enters your stomach and neutralizes acid. Your body doesn’t store sodium bicarbonate. Kidneys and lungs get busy clearing it out. This entire process takes about 6 hours in most healthy adults. If you take a normal antacid dose, baking soda leaves your bloodstream in less than 24 hours.
Folks with slower kidney function, elderly people, or those taking certain medications might not get rid of it as quickly. If your kidneys can’t filter things out well, sodium and bicarbonate stick around. That builds up pressure on the heart and causes other trouble, especially for those with heart or kidney problems.
What Are the Risks?
Baking soda’s not all gentle. Taking too much raises blood sodium, possibly leading to swelling, high blood pressure, and even seizures. It also releases carbon dioxide, which can leave you feeling bloated or gassy. Cases exist where people landed in the hospital after chugging large amounts trying to pass drug tests or relieve chronic heartburn.
The danger isn’t just in regular use. Even a single heavy-handed dose can cause muscle cramps, confusion, and an irregular heartbeat. In one case reported by the American Journal of Emergency Medicine, a man suffered serious health issues after drinking baking soda water after alcohol. Luckily, medical care saved him, but this isn’t some harmless home remedy for everyone.
The FDA recommends adults stick to no more than 3.5 teaspoons spread over a whole day. That includes time between doses, not all at once. Children get lower limits. Your doctor should know if you regularly rely on baking soda to soothe your stomach.
Who Shouldn’t Use Baking Soda?
People with heart problems, high blood pressure, or kidney disease just shouldn’t take baking soda as a remedy. High sodium can tip these conditions into a crisis fast. Certain prescription medications—including diuretics and some antibiotics—clash with sodium bicarbonate, throwing off mineral levels or making medicine less effective.
Pregnant folks and children need special caution. Their bodies process sodium differently, and even a safe dose for an adult might be a problem in smaller or developing bodies.
Safer Solutions for Heartburn
Living with heartburn or acid reflux doesn’t mean you’re stuck with baking soda forever. Dietary adjustments—cutting spicy or fatty food, caffeine, and alcohol—deliver better results without the side effects. Chewing gum, staying upright after meals, and eating smaller portions help, too. If symptoms stick around for weeks or months, consult a doctor. Over-the-counter antacids are designed for safety and don’t bring the same risk of sodium overload.
What This Means for Real Life
Most people clear out baking soda in a day, but the effects—both good and bad—show up quickly. I’ve watched family members chase quick fixes, only to deal with bloating, headaches, or worse. Baking soda can help in rare moments but won’t cure chronic issues. Speak openly with your doctor, especially if you’re trying to solve ongoing stomach problems. Trust your body’s signals and remember: home remedies aren’t always harmless.
