Common Causes of Low Stomach Acid

Stomach acid, also known as gastric acid, plays a vital role in the digestive process, breaking down food and aiding in nutrient absorption.

However, some individuals may experience low stomach acid levels, a condition known as hypochlorhydria.

In this blog post, we will explore the common causes of low stomach acid and the potential implications for digestion and overall health.

• Age: As individuals age, the production of stomach acid naturally declines. This age-related decrease in acid secretion can lead to lower stomach acid levels, impairing the digestion of food and nutrient absorption.

• Chronic Stress: Prolonged stress can negatively impact digestive function, including stomach acid production. Stress activates the sympathetic nervous system, which can inhibit the release of gastric acid. Chronic stress may contribute to hypochlorhydria over time.

• Medications: Certain medications, such as proton pump inhibitors (PPIs), histamine-2 receptor blockers, and antacids, are designed to reduce stomach acid production. Prolonged or excessive use of these medications can contribute to low stomach acid levels.

• H. pylori Infection: Helicobacter pylori (H. pylori) is a bacterium that can infect the stomach lining and cause various gastrointestinal issues, including gastritis and ulcers. While H. pylori infection is associated with increased stomach acid production in the early stages, it can lead to hypochlorhydria over time as the infection progresses.

• Gastric Surgery: Individuals who have undergone gastric surgeries, such as gastric bypass or gastrectomy, may experience reduced stomach acid production. These procedures alter the anatomy and function of the stomach, potentially leading to hypochlorhydria.

• Autoimmune Conditions: Certain autoimmune conditions, such as autoimmune gastritis, can damage the cells in the stomach lining responsible for producing stomach acid. Over time, this immune-mediated damage can result in decreased acid production.

• Chronic Gastritis: Chronic gastritis, characterised by inflammation of the stomach lining, can disrupt the normal functioning of acid-producing cells. Prolonged inflammation can lead to reduced stomach acid levels.

• Genetic Factors: In some cases, genetic factors may contribute to low stomach acid production. Certain genetic variations can affect the function of cells responsible for acid secretion, leading to hypochlorhydria.

Understanding the Implications and Seeking Support: Low stomach acid can have various implications for digestion and overall health. It can hinder the breakdown and absorption of nutrients, increase the risk of gastrointestinal infections, and disrupt the balance of gut microbiota.

Individuals with low stomach acid may experience symptoms such as bloating, gas, indigestion, and nutrient deficiencies.

If you suspect you have low stomach acid, it is crucial to seek guidance from a healthcare professional experienced in digestive health. They can evaluate your symptoms, medical history, and perform appropriate tests to determine if low stomach acid is the underlying cause.

Treatment options may include dietary modifications, supplementation with digestive enzymes or betaine HCl, addressing underlying causes (such as H. pylori infection or autoimmune conditions), and stress management techniques.

Low stomach acid, or hypochlorhydria, can be caused by factors such as age, chronic stress, medications, H. pylori infection, gastric surgery, autoimmune conditions, chronic gastritis, and genetic factors.

Understanding the common causes of low stomach acid is crucial for addressing digestive issues and promoting overall health.

If you suspect low stomach acid, consult with a healthcare professional to determine the underlying cause and develop a personalised treatment plan to optimize digestion and support your well-being.
