Low Stomach Acid



There’s nothing worse than feeling terrible after eating an amazing meal. Post-meal bloating, pain, diarrhea, constipation, a heavy feeling in your stomach, and heartburn are so common today that we think it’s normal. I’ve got news for you; it’s not normal. It’s most likely a case of low stomach acid or no stomach acid levels which results in S.I.B.O.,  but you CAN do something about it! Yes, that’s right, if your stomach acid could be TOO LOW it severely affects not only your digestion but many other functions in your body that may seem entirely unrelated.

According to the book Your Stomach: What is Really Making You Miserable and What to Do About It by Jonathan Wright MD, as many as 90% of Americans are dealing with hypochlorhydria (low stomach acid) or achlorhydria (no stomach acid), many of which are either unaware or being treated for having too much stomach acid, only furthering the problem!

Another resulting factor of long term achlorhydria is S.I.B.O. Which stands for Small Intestinal Bacterial Overgrowth. Which is a common cause of unwanted bloating, abdominal pain, weight fluctuations, and GI distress. There are several books out there on this topic and here are two of my favorites: Healing SIBO: Fix the Real Cause of IBS, Bloating, and Weight Issues in 21 Days by Shivan Sarna

The Typical Diagnosis

Yep, if you describe these symptoms to your doctor, they may tell you the reason for your indigestion and heartburn is from too much stomach acid and give you acid-blocking drugs such as Tagamet or Zantac. These are some of the most prescribed drugs in the pharmaceutical market, making billions of dollars per year for the companies that sell them. The problem with this diagnosis is that, for most of us, the opposite is true. We are deficient in stomach acid, and it is a VITAL part of our overall health and well-being.

The stomach is a highly acidic environment (with a pH of 1.5-3.0) where the food we eat, particularly protein, gets broken down and prepared for absorption by every cell of our body. The proper pH of the stomach then signals the rest of the digestive cascade to continue.

The pancreas and small intestine are called into action to further the break down of the protein, fats, and carbohydrates and deliver them to the cells. Without the high acidity in the stomach, the digestive flow is compromised. This system breaks down causes a dramatic trickle-down effect into all other bodily systems and is the root cause of many other health issues.

By simply increasing stomach acid, so the pH in the stomach is at its optimal level, your meal will be processed correctly, absorbed and assimilated by the body, and the rest of you will stay healthy and happy! As a Nutritional Therapy Practitioner, I help people every single day get back to this optimal state of digestion and see first-hand how simple changes can dramatically improve the life of my clients!

Let’s take a look at how low stomach acid can affect so much more than just the digestive system

Symptoms: Could low stomach acid be to blame?

abnormal digestive function – bloating – diarrhea – constipation – IBS

When stomach acid is insufficient, not only are proteins not properly broken down in the stomach, but the rest of the digestive cascade is compromised. If the chyme (the partially broken down food paste) in the stomach is not acidic enough, the pyloric sphincter will not open. This mechanism allows the food to pass from the stomach into the small intestine to continue digestion. If the pyloric sphincter does not open, the chyme stays in the stomach too long and begins to degenerate.

Proteins putrefy, carbohydrates ferment, and fat becomes rancid. This causes bloating, pain, fullness, and constipation. Once the chyme does make it into the small intestine, the hormone cholecystokinin (CCK) which is needed to trigger the release of bile from the gallbladder for fat digestion will not be released without the chyme being at the proper pH.

The release of secretin is also compromised which stimulates the pancreas to release critical digestive enzymes and sodium bicarbonate to bring the pH of the chyme back to neutral before heading on to the large intestine. Once the maldigested food makes it into the large intestine, the healthy gut flora is disrupted, the tissue becomes inflamed, and harmful bacteria thrive.

low energy – sleepy and sluggish

Vitamin B12 is responsible for nerve and brain function. Depression, sleepiness, and that sluggish feeling arise when we are B12 deficient. This vital vitamin enters the body attached to protein and needs to be cleaved off for absorption to take place. Hydrochloric acid and pepsin are necessary in sufficient quantity to complete the separation of protein and vitamin B12 in the stomach.

Another interesting factor is that if food is sitting on your stomach most of the night due to the low stomach acid level slowing down the entire process then your brain may sleep, but your body will still be awake trying to digest the contents of your stomach.

muscle wasting – hair loss – aging skin – cracked/peeling fingernails

Amino acids are the compounds that make up proteins and what are left once proteins are broken down in the digestive system. They are essential to the growth and development of many different structures in the body including muscle fibers, hair structure, nails, bones, skin, nerves, neurotransmitters, and hormones. They are also the creators of collagen and elastin, the binding substances needed for clear, wrinkle-free, healthy skin. With low stomach acid and the inability to properly break down proteins, amino acids aren’t available in the body to do all of these critical functions which will show up in the health of your hair, skin, and nails.

Additionally, the body will break down muscle in an attempt to get the essential amino acids. This leads to decreased muscle mass, strength, and potential weight loss.

depression – mood disturbances

The gut is often considered our second brain with the majority of our neurotransmitters and serotonin (the happy chemical) being made in the gut. Amino acids are needed to build neurotransmitters which are the brain’s “messengers.” Decreased stomach acid = decreased amino acids = decreased serotonin production = decreased happiness!

leaky gut – autoimmune diseases – food allergies and sensitivities

Without the stomach being at the proper highly acidic level needed to break down food completely, large amounts of protein go undigested, making their way down through the digestive tract into the small intestine. The lining of the small intestine becomes inflamed, and the once tightly-bound villi that line and protect the walls loosen up and create holes.

This is known as intestinal permeability or leaky gut. Now, the undigested proteins pass through the intestinal lining and into the bloodstream. As our body is meant to do, it attacks these foreign invaders that have made it into our bloodstream. This attack causes an allergic response. In cases of food allergies, the body now considers this undigested food particle to be an allergen and will attack it anytime it comes back into the bloodstream. A food allergy is born and will continue until the intestinal walls are sealed again and the food is unable to make its way into the bloodstream.

In cases of autoimmune diseases, the immune system continues this attack on other cells in the body that look similar to the invading proteins, causing otherwise healthy tissues and organs to be under attack. This can happen to many different tissues within the body such as the thyroid (Hashimoto’s and Graves’ disease), the joints (rheumatoid arthritis), the GI tract (Crohn’s, ulcerative colitis), the nerves (multiple sclerosis), and many many others. According to Wright, “A mainstay for treatment for ANY autoimmune disease is the examination for and (when found) treatment of low stomach acid and other digestive malfunction.”

dysbiosis – bacterial imbalance – candida, parasites, and fungal overgrowth

Stomach acid kills harmful bacteria. A healthy digestive system is a home to billions of bacteria, the majority of which are good. However, even the healthiest of guts are still home to harmful bacteria. These healthy guts can manage the bad bacteria and keep it in check, allowing for ‘bacterial harmony.’ Problems arise when these bad bacteria begin to thrive and grow, make a home in the gut, and take over the good bacteria. So, how do these bad guys get in? Through a stomach, with a pH higher than 5. (Remember, normal pH of a healthy stomach is between 1.5-3.0.) The acidity in a stomach that’s not producing enough HCL becomes a breeding ground for bacteria.

hormonal imbalances

It takes a lot of nutrients to build hormones, but the most essential nutrient needed is fat and more specifically cholesterol. When the stomach is not in the optimal pH range, the gall bladder is not triggered to release bile which breaks down fats. Therefore, the fats go undigested, and the building blocks of hormones are absent. All hormone levels will take a hit including testosterone, progesterone, and estrogen.

acne – rosacea – dermatitis

Acne and other skin manifestations have a high correlation to the health of the gut. When the gut is leaky, foreign objects and bacteria make its way into the bloodstream, causing an allergic reaction. This can manifest in the skin in the form of acne, rosacea, and dermatitis.

bad breath

Bacteria thriving in a stomach without enough hydrochloric acid emit an order that shows itself in your breath!


Calcium is a super essential mineral to many processes in the body including maintaining bone strength. Calcium cannot be adequately broken down and absorbed without enough stomach acid. Calcium deficiency leads to brittle bones that can easily break, which is known as osteoporosis.

rheumatoid arthritis

Many studies have been done over the past 100 years linking RA patients and low stomach acid. According to Wright, “People with rheumatoid arthritis have an extremely high rate of atrophic gastritis associated with low stomach acid compared with normal individuals.” This is an important factor in getting over RA. We will post a complete article on overcoming RA in the future.

blood sugar imbalance – sugar cravings

Amino acids have another function besides being essential building blocks for every part of our body. They also maintain blood sugar and proper insulin levels. When protein breaks down is compromised, and available amino acids are low, blood sugar levels can become imbalanced, and sugar cravings will ensue.


Another important nutrient that will not be adequately absorbed is iron. Deficient iron absorption can zap muscle strength and drain stamina, leaving you feeling weak and tired. According to Wright, “it comes as no surprise that when supplementary HCL is given to people with anemia and low stomach acid, their iron absorption improves and their anemia disappears.”

insistent hunger – uncontrollable appetite – weight gain – inability to lose weight

As described in this post, the trickle-down effect from low stomach acid can lead to many seemingly unrelated conditions such as nutrient deficiency, malabsorption, hormonal imbalance, muscle wasting, and adrenal fatigue.  All of these contribute in their way to an unhealthy, sluggish metabolism and overeating. For example, if the body is not sufficiently producing the hormone ghrelin (the hunger hormone),  you won’t get the ‘full’ signal during a meal and will likely overeat. Or, if your body is perceiving a state of high stress causing high levels of cortisol, the appetite is known to increase during this time. The body’s perceived starvation from not properly absorbing the food that we eat is another reason for increased appetite.

asthma – allergies

Known to be an inflammatory reaction in the lungs due to allergens, asthma can be traced back to the health of the gut and more importantly to the pH of the stomach and food allergies. In response to this Wright say “…a vicious circle soon ensues in which an allergic reaction to food inflames the gastric and intestinal linings, inhibiting HCL secretion and promoting allergic reactions all over the body, not just to foods, but to inhalants and microorganisms, as well.”

high cortisol – adrenal fatigue

Adrenal fatigue can be considered the “stress illness.” Now that we’ve gone through this list of things that can go wrong with your health when you have low stomach acid, wouldn’t you agree that any of them would put a significant level of stress on your body?! Food isn’t being broken down which leaves us malnourished and unable to properly build every cell in our body to regulate every function of our being. The body sees this as a stressful situation and engages in ‘fight or flight’ mode, bringing cortisol into play to help out in this time of stress.

Does this sound like you?

I’ve got great news for you! There are several things you can easily incorporate into your daily routine to help support your digestion and increase natural stomach acid production.

  • Drink water with lemon 30 minutes before your meals.
  • Take three deep breaths before your first bite. This will help you get into ‘rest and digest’ mode which is needed for the proper secretion of gastric juices.
  • Eat slowly and chew thoroughly. Aim to chew each bite 30 times. If necessary put your fork down between bites.
  • Avoid drinking any liquid during the meal. This will dilute the gastric juices.
  • Avoid consuming liquid foods like watered down soups because this too dilutes the gastric juices.

In some cases it may be necessary to support your digestion with Doctor’s Best Betaine HCl Pepsin and Gentian Bitters supplementation is the most effective way to get significant and immediate symptom relief. Found in almost all health food stores, this supplement provides the stomach acid that is missing in the same form as the stomach produces naturally, hydrochloric acid. It also contains Gentian Bitters an herb used to promote digestive capacity and tonify the digestive tract. Its bitter nature helps to stimulate the body’s production of digestive enzymes.

Causes: Prevention is the best cure.

To prevent something we need to know what caused it in the first place. Hydrochloric levels can naturally decrease as we age. We can also decrease the levels of hydrochloric acid by abusing our stomachs. Here’s a list of most causes of low hydrochloric acid:

  1. Eating meals too fast – chew for 30 seconds before swallowing
  2. Overeating – eat only enough to satisfy your hunger not your appetite
  3. Meals too close together – leave 5-6 hours between meals to digest and recover or rest
  4. Eating late at night – do not eat any later than 2 hours prior to going to bed
  5. Eating between meals – no snacking, nothing but water in-between meals
  6. Eating when tired
  7. Loss of sleep – the hours before midnight (8-12) can be equal to 2 after midnight
  8. Nervousness – “Come unto me, all ye that labour and are heavy laden, and I will give you rest.” – Matthew 11:28
  9. Mental depression
  10. Unripe fruit – Unripe fruit should never be eaten raw. When cooked, unripe fruit is less objectionable, but it may still cause harm.
  11. Spoiled food – don’t keep food in the fridge longer than 3 days
  12. Condiments – Mustard, pepper, spices, pickles, and other things of a like character, irritate the stomach and make the blood feverish and impure.
  13. Bread not well done – yeast bread should have little moisture left in it after baking
  14. Fresh bread – wait for 24 hours before eating yeast bread to leave sufficient time for the alcohol to evaporate
  15. Vinegar – When ingested fermentation takes place in the stomach, and the food does not digest, but decays or putrefies; as a consequence, the blood is not nourished, but becomes filled with impurities, and liver and kidney difficulties appear. This is the case with all forms of vinegar.
  16. Fried Food
  17. Complex Mixtures – 3-4 dishes max
  18. Combination of fruits and vegetables – When combined at the same meal one must wait on the other to be broken down and while waiting it ferments.
  19. Combination of milk and sugar – The free use of milk and sugar combined are liable to cause fermentation in the stomach, and are thus harmful.
  20. Refined sugar or to much sweets – If your food’s to sweet it can be an active causes of indigestion.
  21. Tea, coffee, and cocoa
  22. Too much liquid with food or drinking with meals
  23. Same food every day
  24. Soft drinks
  25. Chewing gum – When you chew gum your mouth is producing enzymes which go down your esophagus to your stomach and in turn produce HCL, but if there’s nothing to digest then the result can be as bad as stomach cancer.
  26. Loss of minerals (e.g. potassium, calcium, or iron which attracts oxygen which is essential for body metabolism)
  27. Aluminum – Do not use aluminum cookware.

Cause of allergies:

If your not digesting your food properly or the stomach is not producing sufficient HCL to digest your food properly, particularly protein, then the result is you develop auto-immune disease, leaky gut, and/or inflammatory actions (IBS) that result in allergies.

Pollen does not cause allergies. The problem is the immune system has been compromised. The pollen has protein in it which we inhale and if the body produces sufficient hydrochloric acid (HCL) the body will break it down and eliminate the toxin.

Understanding the process of digestion:

Digestion is the conversion of large foodstuffs into units small enough to be used by the cells. The starches become glucose, fats become fatty acids, and proteins become amino acids. The blood then picks up these substances from the intestines (absorption). You are what you digest.

“Our bodies are built up from the food we eat. There is a constant breaking down of the tissues of the body; every movement of every organ involves waste, and this waste is repaired from our food. Each organ of the body requires its share of nutrition. The brain must be supplied with its portion; the bones, muscles, and nerves demand theirs. It is a wonderful process that transforms the food into blood and uses this blood to build up the varied parts of the body; but this process is going on continually, supplying with life and strength each nerve, muscle, and tissue.”— Ministry of Healing, p. 295.1

The Five Food Labs and Body Chemistry / Digestion Time

The Mouth – Alkalinizes 1-5 minutes
The Stomach – Acidifies 4.5 – 5 hours
The Small Intestines – Alkalinizes 7.5 hours
The Liver – Alkalinizes
The Colon – Acidifies 12 hours

Did you catch that? That’s a total of 24-25 hours for food to pass through the system and come out the other end. If your digestion time is different then you need to ascertain the cause, change unhealthful conditions, correct wrong habits, and lastly assist nature to expel wastes and re-establish right conditions in the system.
