Why can't people with hypertension drink soda?

Hypertensive patients should avoid drinking soda water, generally to prevent abnormal effects on blood pressure.

Soda water typically contains 0.4–0.6g of sodium bicarbonate, or it may be plain water or beverages saturated with carbon dioxide. It often contains mineral ions and trace elements such as boron, zinc, selenium, and chromium. Drinking moderate amounts can help supplement essential minerals, neutralize the body's acidic environment, and alkalize urine to achieve acid-base balance. However, because soda water contains relatively high levels of sodium ions, habitual consumption by hypertensive patients increases sodium intake, leading to elevated blood sodium concentration. This makes blood pressure control more difficult and increases the risk of cardiovascular events. Therefore, hypertensive patients are generally advised not to drink soda water.

In daily life, hypertensive patients need to actively quit smoking and alcohol consumption, maintain an optimistic and calm mindset, engage in appropriate physical exercise, follow regular dietary habits, and avoid foods high in salt, fat, and sugar, all of which contribute to stable blood pressure.
