STOMACH ACID IS AN ESSENTIAL COMPONENT OF DIGESTION AND OVERALL GUT HEALTH
Occasional indigestion is estimated to impact up to 20% of the US population[1]. While too much stomach acid can cause digestive discomfort for some people, low stomach acid is the more likely culprit[2]. When there is not enough stomach acid to start the digestive process, activate digestive enzymes, and stimulate gut movement, food ends up sticking around in the stomach for too long. This can then cause uncomfortable indigestion and other digestive symptoms.
BIOptimizers HCL Breakthrough is designed to support digestion by improving stomach acidity and adding to the stomach’s digestive capacity with plant-based digestive enzymes that work well in acidic pH. This helps your body better digest food and absorb certain nutrients.
How to Know if You Have Low Stomach Acid
Low stomach acid can be difficult to recognize - signs can be very similar to having too much stomach acid.
Low stomach acid symptoms:
- Occasional discomfort, indigestion, and bloating, especially after high-protein meals
- Prolonged fullness or stomach sensation after eating, especially with high-protein or high-fat meals
- Difficulty digesting meat and meat aversion
- Suboptimal digestion, with partially digested foods in your stool
- Deficiencies of nutrients that require stomach acid to absorb, such as vitamin B12, iron, calcium, zinc, and magnesium.
- Fatigue after meals as the digestive process requires more energy
Certain conditions can cause low stomach acid, including alcohol use, surgeries, autoimmune conditions, infections, and medications. Low stomach acid is also more common in older adults. You should speak to your doctor to rule out serious causes.
LOW STOMACH ACID TEST
There are a few reliable ways to test whether you have low stomach acid or not. A proper evaluation by a healthcare provider is the most reliable way to understand what’s going on. Testing options may include:
Aspiration test uses a tube inserted into the bottom of the stomach, and acid output can be measured over the course of an hour. Another way is by using a probe placed in the stomach that can collect data on gastric pH. These tests are invasive, and not readily available to most people.
Blood tests may identify diagnosable serious causes of low stomach acid that require medical interventions. These include:
- Anti-parietal cell antibodies can detect antibodies against acid-producing cells in your stomach.
- Anti-intrinsic factor detect antibodies against intrinsic factor, which is necessary for vitamin B12 absorption.
- Pepsinogen, a pro-enzyme produced in the stomach. Changes in ratios of pepsinogen can indicate inflammation of the stomach.
- Stomach gastrin levels, a stomach hormone. Abnormal levels can indicate issues with the stomach.
Nutrient status tests may identify nutrient deficiencies that often relate to low stomach acid
- Complete blood count and iron panel, including ferritin, serum iron, transferrin, and total iron binding capacity, can diagnose an iron deficiency or iron deficiency anemia.
- Vitamin B12 levels can diagnose a vitamin B12 deficiency. Stomach acid helps liberate vitamin B12 from foods in the stomach, so low stomach acid can cause a vitamin B12 deficiency..
Serum levels of magnesium, calcium, and zinc may not be indicative of the total body status of these minerals.
Other diagnostic tests
Your doctor may want to rule out infections including:
- Helicobacter pylori, which can decrease stomach acid
- Small Intestine Bacterial Overgrowth, which often occurs with low stomach acid
Baking soda tests are quick at-home tests that might also help you differentiate. It involves drinking a solution of ¼ teaspoon of baking soda and half a cup (120 mL) of water, which can estimate stomach acid based on how quickly you burp. People with adequate stomach acid should burp in 3 - 5 minutes as the baking soda reacts with stomach acid. However, it is not the most adequate test, especially because most of your stomach acid is secreted once food reaches the stomach.
CRUCIAL ROLES OF STOMACH ACID
Your stomach plays many key roles in helping your body digest, extract energy, and absorb nutrients from food. It does this by secreting stomach acid, more properly known as hydrochloric acid (HCl). HCl is made by parietal cells, which are embedded in the stomach lining[3]. HCl secretion is stimulated when food enters the stomach, and it plays a critical role in your body’s digestive processes[4]:
- Assists in breaking down ingested food into chyme, a semi-liquid substance with semi-broken down foods. This helps prepare it for further digestion in other areas of the digestive tract.
- Activates enzymes. The acidity helps convert inactive enzyme pepsinogen into its active form, pepsin, and prorenin into rennin. Pepsin is responsible for breaking down proteins into smaller snippets called peptides. Rennin helps with the digestion of milk protein, casein. Without enough HCl, protein digestion can be compromised and may lead to poor digestion.
- Stimulates the release of gastrin, a hormone that helps regulate acid production and food movement through the stomach and intestines. Gastrin promotes muscle contractions in the stomach, which helps speed up gastric emptying.
- Helps absorb many key nutrients – vitamin B12, iron, calcium, magnesium, and zinc [5]. The stomach acid dissociates, dissolves, and ionizes these nutrients into forms that the intestine can absorb. When stomach acid levels are low, nutrient absorption may be less efficient.
- Creates inhabitable environment for microbes. By maintaining a naturally acidic environment (pH between 2.9 and 3.5), the stomach becomes inhabitable to most microorganisms found in foods.
- Stimulates digestive secretions. Once food travels from the stomach to the lower intestine, the acidity also signals the release of other digestive secretions – bile, bicarbonate, and pancreatic enzymes. These are crucial for additional digestion and gut movement throughout the rest of the digestive process.
- Promotes peristalsis - the rhythmic contraction and relaxation of muscles in the digestive tract that help move food along. It does this by activating a mechanism called the enterogastric reflex, a response that helps regulate the movement of food through the digestive tract [6]. This reflex helps coordinate peristaltic waves by signaling to the intestines to contract as food is absorbed.
Given stomach acid’s crucial natural roles, suboptimal stomach acid can have ripple effects throughout the digestive tract and the body.
