There is no so-called “fastest and most effective” way to treat stomach acid, you can take drugs that inhibit stomach acid, protect the gastric mucosa, and promote gastric motility, such as omeprazole enteric-coated tablets, magnesium alumina carbonate chewable tablets, domperidone and so on.
Gastric acid is related to gastritis, gastric ulcer, bile reflux esophagitis and so on, which will cause acid reflux, heartburn, bloating and other symptoms. Or acid reflux caused by physiological factors, such as consuming too much acidic food, resulting in excessive secretion of gastric acid, which can recover on its own.
Excessive acid secretion can be treated with oral medication or by reducing the intake of acidic foods. For example, if it is caused by the infection of Helicobacter pylori, it is necessary to remove the Helicobacter pylori first, and you can choose two antibiotics, a bismuth agent, and an acid suppressant to treat it, such as amoxicillin capsule, clarithromycin capsule, omeprazole enteric-coated tablets, bismuth potassium citrate, and so on.
Appearance of stomach acid should go to the gastroenterology department to find a doctor for treatment, do not take medication on your own, you must follow the doctor’s instructions.
