Low stomach acid (hypochlorhydria) is more common than many people realize and can contribute to symptoms such as bloating, excess gas, belching, acid reflux, and feeling overly full after meals. It may also reduce the absorption of important nutrients, including iron, vitamin B12, calcium, magnesium, and zinc, increasing the risk of nutrient deficiencies over time.Several factors can contribute to low stomach acid production, including aging, long-term use of acid-suppressing medications, chronic stress, nutrient deficiencies (particularly zinc), chronic inflammation of the stomach lining, and infection with Helicobacter pylori.Personalized care involves assessing digestive symptoms through a comprehensive history, medication review, laboratory testing, and functional testing when appropriate. Treatment focuses on identifying and addressing the underlying cause, supporting healthy stomach acid production, optimizing digestion, correcting nutrient deficiencies, and restoring overall digestive health with individualized nutrition, lifestyle, and supplement recommendations.
