Digestive Health Series Part 2: Stomach Acid

Richmondchironeu • July 1, 2019

Hello again everyone:

As we continue this series, we will answer several questions: what does stomach acid do for us; what are the signs or symptoms that it may be low; what causes low stomach acid.

What does stomach acid do for us? Adequate stomach acid is essential for multiple functions: digestion of protein; absorption of minerals and especially iron, zinc and magnesium; absorption of vitamins, especially B-12; a first layer of defense against infection as the acid kills pathogens; assists in breaking down food to small particles which lowers the risk of food allergies (also known as loss of oral tolerance). When stomach acid is low, it can cause the lower esophageal sphincter muscle to relax and allow acid to go into the esophagus and cause heartburn and/or reflux. Also, when acid is low, food will literally rot…and this can happen incredibly fast. Proteins will putrefy, carbohydrates will ferment, and fats can go rancid…leading to a very nasty situation as they rise up into the esophagus and cause uncomfortable bloating.

Symptoms  such as heartburn, reflux, gas, pain, bloating, loose stools or constipation, digestive discomfort, burping or belching, bad breath, hair loss, intestinal infections, nausea with taking supplements, undigested food in the stool, upset stomach as well as links to skin problems, auto-immune conditions like psoriasis, allergies, anemia, asthma and more.

The above are all signs and symptoms of low acid, and if you were to consult with your primary care physician with those symptoms, you would most likely receive a prescription for an acid blocker. Unfortunately, if you have low stomach acid like most of us, this will only compound the problem as it does nothing for the underlying problems that caused the issue in the first place.

Causes or risk factors:

Here are some of the more common ones: age (sorry); stress; diet; auto-immune family history or personal history or auto-immune disorder(s); a diet low in zinc; gut infection; history of stomach surgery; some medications; food allergies, sensitivities or intolerances, especially gluten issues

Bottom Line:  You can see how stomach acid can play a role in many conditions. In the next newsletter, I will go over what you can try at home. See you next week!

Health News Update: Happy New Year 2026! 1.5.26 Hey there everyone: Here is some news you can use to help you age optimally. I have written before about circadian rhythms and meal timing where it has been shown that eTRF (early time restricted feeding) has many benefits. But what happens as we age and shift our mealtimes away from our natural circadian clocks? Here are some snippets from this paper: “Chrononutrition, the study of the timing of eating, has emerged as a modifiable risk factor for adverse health outcomes The role of eating schedules is biologically relevant as dietary intake acts as an environmental cue influencing the circadian clocks of peripheral metabolic tissues and therefore can contribute to circadian misalignment and internal desynchrony 2 , 10 . The emerging evidence largely suggests that later mealtimes, particularly eating during the biological evening, is detrimental to health, Physical and psychological illnesses, including fatigue, oral health problems, depression, anxiety, and multimorbidity, are primarily associated with later breakfast. Later breakfast timing is also associated with increased mortality Importantly, eating breakfast later with aging was linked to a higher risk of death” https://www.nature.com/articles/s43856-025-01035-x meal timing important for health Bottom Line: While this paper focuses on the elderly, it is certainly applicable to all of us. I have seen significant health benefits when people adopt eTRF patters…from better digestion to weight loss, to better sleep, to more energy!
