Low Stomach Acid – Why Your Digestion Might Be Struggling

Ever had the strange experience of burping up spaghetti… two days after you ate it? That’s a sign your food hasn’t been properly digested and has been sitting in your stomach fermenting. Spaghetti, like bread and pasta, is an alkaline food, which means your stomach needs to produce a lot of acid to break it down.

Food doesn’t leave the stomach until its pH drops to around 2 or 3. Normally, your stomach’s resting pH is closer to 4. So, when you eat alkaline foods with a pH around 8 or 9, your stomach must work harder to create the acid needed for digestion. If this process takes longer than about two hours, the warm environment (98.6–99.2°F) causes the food to start fermenting — much like food going stale when left out for too long.

If your stomach acid is too low, this breakdown process is delayed, and food remains in the stomach far too long. When it eventually passes into the rest of your digestive system, it’s in a toxic, fermented state — irritating your gut lining and, if absorbed, causing issues throughout the body.

What Happens When Poorly Digested Food Moves On

Once putrefied food leaves the stomach, it enters the small intestine. Here, the pancreas steps in, working overtime to release extra digestive enzymes to try to salvage the process. This constant strain can leave the pancreas fatigued, and it may even start borrowing enzymes from other systems in the body — ultimately slowing your overall metabolism.

Common Causes of Low Stomach Acid

Several factors can interfere with proper stomach acid production:

• Ongoing stress
• Diets high in processed foods or low in essential minerals
• Smoking
• Certain medications
• Helicobacter pylori infection (which neutralises stomach acid to survive)
• Excess alcohol or caffeine
• Low-protein, high-carbohydrate diets
• Ageing (HCL production tends to decline over time)
• Underactive thyroid
• Zinc deficiency (a cycle where low zinc reduces stomach acid, and low stomach acid limits zinc absorption)
• History of eating disorders

How to Support Healthy Stomach Acid Levels

Foods rich in natural acids — such as leafy greens and citrus fruits — can help restore a healthier pH in your stomach. If you’re eating alkaline foods like bread, pasta, or certain animal proteins, be sure to balance them with these acidic foods. This not only improves digestion but can also encourage your stomach to produce more acid naturally.
