Estimated reading time: 4 min


Low stomach acid, also known as hypochlorhydria, is a condition where the stomach produces an insufficient amount of gastric acid. Stomach acid, primarily composed of hydrochloric acid (HCl), plays a crucial role in the digestive process by breaking down food, particularly proteins, and facilitating the absorption of nutrients. When the production of stomach acid is reduced, it can lead to various digestive problems.


Digestive Symptoms:

1. Indigestion: Individuals with low stomach acid may experience persistent indigestion, bloating, and discomfort after meals.

2. Gas and Bloating: Incomplete digestion of food can lead to the formation of gas in the digestive tract, causing bloating and flatulence.

3. Feeling Full Quickly: People with low stomach acid may feel full shortly after starting a meal, even if they have not eaten much.

4. Nutrient Malabsorption:
Stomach acid is essential for the proper breakdown of proteins and the absorption of nutrients, including minerals (such as iron and calcium) and vitamins (especially B12). Low stomach acid can contribute to deficiencies in these nutrients.

5. Incomplete Protein Digestion:
Proteins require an acidic environment for optimal digestion. Insufficient stomach acid can result in incomplete protein breakdown, leading to the absorption of partially digested proteins. This can contribute to food sensitivities and allergies.

6. Weak Immune Response:
Adequate stomach acid helps protect the body from harmful bacteria and pathogens present in ingested food. Low stomach acid may compromise this protective function, potentially increasing the risk of infections.

7. Heartburn and Acid Reflux:
While it may seem counterintuitive, low stomach acid can sometimes lead to symptoms that resemble acid reflux. This is because undigested food in the stomach can put pressure on the lower esophageal sphincter, allowing stomach contents to flow back into the esophagus.

8. Nausea and Vomiting:
Some individuals with low stomach acid may experience nausea and, in severe cases, vomiting.


The treatment for low stomach acid, or hypochlorhydria, depends on the underlying cause. It’s crucial to consult with a healthcare professional for proper diagnosis and guidance on the most appropriate treatment. Here are some general approaches that may be considered:

1. Dietary Changes:
Bitter Foods: Including bitter foods in the diet, such as arugula, kale, and other leafy greens, may help stimulate the production of stomach acid.
Apple Cider Vinegar: Some people find relief by incorporating diluted apple cider vinegar before meals, as it may promote digestion.
Digestive Bitters: Herbal supplements containing digestive bitters can stimulate the production of digestive juices, including stomach acid.

2. Avoidance of Acid-Suppressing Medications:
If low stomach acid is associated with the long-term use of acid-suppressing medications (such as proton pump inhibitors or antacids), a healthcare professional may gradually taper off or adjust the dosage of these medications.

3. Addressing Underlying Conditions:
If an underlying condition, such as H. pylori infection or autoimmune gastritis, is identified as the cause of low stomach acid, treating that condition may help restore normal acid production.

4. Lifestyle Changes:
Stress Management: Addressing chronic stress through relaxation techniques, mindfulness, or other stress management strategies may positively impact digestive function.

5. Eating Habits: Adopting healthy eating habits, such as eating smaller, more frequent meals and avoiding overeating, can support digestion.

6. Medical Supervision:
Any treatment for low stomach acid should be done under the supervision of a healthcare professional. Self-diagnosis and self-treatment without proper guidance can lead to complications.

Nutrients and supplements:
1. Digestive Enzymes:
Digestive enzyme supplements can aid in the breakdown of proteins, fats, and carbohydrates. Look for a broad-spectrum digestive enzyme supplement that includes protease, lipase, and amylase.

2. Zinc:
Zinc is a mineral that plays a role in the production of stomach acid. A healthcare professional may recommend zinc supplementation if a deficiency is identified.

3. Probiotics:
Probiotics are beneficial bacteria that can support gut health. While they don’t directly increase stomach acid, maintaining a healthy balance of gut bacteria may positively influence overall digestion.

4. Apple Cider Vinegar:
Some individuals find relief by incorporating diluted apple cider vinegar before meals. It is believed to stimulate the production of stomach acid. However, its use should be monitored, and it may not be suitable for everyone.


Low stomach acid, or hypochlorhydria, can result from various factors. Here are some potential causes:

1. Aging:
Stomach acid production tends to decrease with age. Older individuals may produce less stomach acid compared to younger people, which can contribute to digestive issues.

2. Chronic Stress:
Prolonged periods of stress can affect the nervous system and may influence the production of stomach acid. Chronic stress can lead to changes in digestive function, potentially reducing stomach acid levels.

3. H. pylori Infection:
Helicobacter pylori is a bacterium that can infect the stomach lining, leading to inflammation and the production of less stomach acid. In some cases, the body’s response to an H. pylori infection can result in reduced acid secretion.

4. Antacid Use:
The long-term use of antacids or proton pump inhibitors (PPIs), which are medications commonly prescribed for acid reflux and heartburn, can suppress stomach acid production. While these medications can be beneficial for certain conditions, extended use without medical supervision may contribute to low stomach acid.

5. Autoimmune Conditions:
Certain autoimmune conditions, such as autoimmune gastritis, can damage the cells in the stomach lining that produce acid. This autoimmune response can lead to a reduction in stomach acid levels.

6. Nutrient Deficiencies:
Deficiencies in key nutrients, such as zinc, vitamin B1 (thiamine), and chloride, can impact the body’s ability to produce sufficient stomach acid.

7. Inflammatory Bowel Disease (IBD):
Conditions like Crohn’s disease or ulcerative colitis, which are inflammatory bowel diseases, can affect the digestive tract and potentially reduce stomach acid production.

8. Gastric Surgery:
Certain types of gastric surgery, such as partial or complete removal of the stomach (gastrectomy), can result in reduced acid production.

9. Zinc Deficiency:
Zinc is a mineral that plays a role in the production of stomach acid. A deficiency in zinc may contribute to low stomach acid levels.

10. Genetic Factors:
There may be a genetic predisposition to low stomach acid in some individuals.

Underlying Emotions


Drinking sufficient water is important for overall health, including digestion. However, it’s advisable to avoid excessive fluid intake around mealtime, as this may dilute stomach acid.

1. Chew Food Thoroughly:
Chewing food thoroughly promotes the mechanical breakdown of food before it reaches the stomach, supporting the digestive process.

2. Smaller, More Frequent Meals:
Instead of large meals, consider eating smaller, more frequent meals throughout the day. This can help manage the digestive workload and reduce the demand on stomach acid.

3. Limit Highly Processed Foods:
Processed and refined foods may be harder to digest. Focus on whole, nutrient-dense foods that are easier on the digestive system.

4. Avoid Overconsumption of Fluids During Meals:
While staying hydrated is important, excessive fluid intake with meals may dilute stomach acid. Consider consuming fluids between meals instead.

5. Limit Caffeine and Alcohol:
Both caffeine and alcohol can potentially irritate the digestive tract. Limiting their intake may be beneficial for some individuals.

6. Identify and Address Food Sensitivities:
Some individuals with low stomach acid may have food sensitivities. Identifying and eliminating potential trigger foods can be part of a personalized approach.
