Hydrochloric Acid In The Stomach
Hydrochloric acid is a primary component of your stomach acid, accounting for 0.5 percent of its total volume however, that’s not the only important substance. Stomach acid also contains large amounts of potassium chloride and sodium chloride.
Together, these substances give stomach acid a pH of around 1 to 2, which is almost as acidic as you can get on the pH scale. According to the February 2012 issue of ChemMatters, a publication produced by the American Chemical Society, your body makes two to three liters of stomach acid every day.
Even though stomach acid is so acidic, it doesn’t cause any harm to your stomach because the body has built-in mechanisms to protect the stomach’s lining from being eaten away by the acid.
Mucus cells are the most abundant cells in your stomach lining. These mucus cells release mucus that coats the entire inside of your stomach. The mucus doesn’t just form a physical barrier to HCl it also contains high volumes of bicarbonate, which helps neutralize the acid when it comes into contact with your stomach lining.
Because of this advanced biochemical system, the hydrochloric acid in your stomach is able to perform its jobs without hurting you.
Cut Down On Processed Foods
Cleaning up your diet is another great way to improve your stomach acid. Limit processed foods and sugars, as these can cause inflammation in your stomach, lower acid, and even trigger acid reflux, Zellner says. Meanwhile, a diet rich in fruits and vegetables may lower inflammation and boost stomach acid.
How Does The Stomach Work
The stomach is a muscular hollow organ. It takes in food from the esophagus , mixes it, breaks it down, and then passes it on to the small intestine in small portions.
At the point where the esophagus leads into the stomach, the digestive tube is usually kept shut by muscles of the esophagus and diaphragm. When you swallow, these muscles relax and the lower end of the esophagus opens, allowing food to enter the stomach. If this mechanism does not work properly, acidic gastric juice might get into the esophagus, leading to heartburn or an inflammation.
The upper-left part of the stomach near the opening curves upward towards the diaphragm. This part is called fundus. It is usually filled with air that enters the stomach when you swallow. In the largest part of the stomach, called the body, food is churned and broken into smaller pieces, mixed with acidic gastric juice and enzymes, and pre-digested. At the exit of the stomach, the body of the stomach narrows to form the pyloric canal, where the partially digested food is passed on to the small intestine in portions.
The stomach wall is made up of several layers of mucous membrane, connective tissue with blood vessels and nerves, and muscle fibers. The muscle layer alone has three different sub-layers. The muscles move the contents of the stomach around so vigorously that solid parts of the food are crushed and ground, and mixed into a smooth food pulp.

What Are The Causes
Stomach acid is one of the tools that the digestive system uses to transform the raw materials of our food into the nutrients and energy needed to keep us alive.
Too much acid in your stomach can overwhelm the prostaglandins in your stomach and duodenum. These hormones help protect the lining of your stomach, but if they are overwhelmed, it can cause ulcers as well as a host of other symptoms.
Certain conditions can cause your body to produce too much gastric acid. These include:
Possible Symptoms And Treatment
Symptoms of low stomach acid may include stomach discomfort, bloating, heartburn, and/or nausea. These symptoms can also be caused by other conditions, however. A doctor should be consulted if the symptoms are present in order to receive a diagnosis for the problem.
Someone with either hypochlorhydria or achlorhydria should be under a doctorâs care. Treatment will likely be aimed at removing the cause of the low acid production and/or at compensating for any chemical or nutritional deficiencies.

Acidic Tummy: Things To Remember
Acid reflux disease is a common condition and is on the rise in the western world, alongside diseases such as obesity and diabetes. This is largely due to the western diet which has poor nutritious quality and sedentary lifestyles. But there are things you can do to reduce the risk of acid reflux disrupting your life. Just remember:
- Acid reflux is not caused by too much stomach acid.
- Acid reflux happens when stomach acid travels back into your oesophagus.
- If it happens more than twice a week, its gastroesophageal disease .
- Extra weight on your waist is linked to acid reflux.
- Your lifestyle can help prevent or encourage acid reflux.
- There could be a link between the condition and gut dysbiosis.
- Ask your doctor about heartburn, its a proper medical problem.
- Surgery is a last resort in many cases of GERD.
- A fibre-rich diet, gentle exercise, quitting smoking, and weight loss can help.

Interestingly, pregnant women are more susceptible to acid reflux, particularly in the later stages because the baby begins to push upwards onto the stomach. Lets face it, theres not much room in there! Thankfully though, it usually goes away once the baby is born, although some women experience heartburn for a little while after.

There Are Three Phases In The Secretion Of Gastric Acid:
What Protects The Stomach From Hydrochloric Acid
Several mucosal defense systems protect the stomach from hydrochloric acid and other unpleasant substances. The mucus-bicarbonate barrier provides pre-epithelial protection. Mucus and bicarbonate, released by mucus cells, provide a pH gradient that keeps the epithelial cell surface close to neutral. The protein zonulin is also important for maintaining normal stomach permeability. When zonulin is reduced or absent, the intestinal lining becomes more vulnerable to damage caused by acidic foods and chemicals.
Stomach cancer is one of the most common forms of cancer in the world. There are several factors in place that can increase your chances of developing this disease including alcohol consumption, tobacco use, eating a poor diet full of processed foods and less than five servings of fruits and vegetables per day. In addition, H. pylori infection has been linked to stomach cancer. This bacteria lives in the stomach and duodenum and many people carry it without any problems. However, if you have other risk factors for stomach cancer such as family history or previous history of cancer, then getting tested for H. pylori is recommended.

Limit Refined Carbohydrate Intake
Making certain dietary changes may help increase stomach acidity. For example, diets that are high in refined carbohydrates may lead to inflammation in the stomach and other digestive organs.
Although some research suggests that the inflammation is directly due to refined carbohydrates and excess sugar, some experts suggest that it may be due to an overgrowth of yeast fungi in the stomach that causes diarrhea, bloating, and constipation.
Proponents may suggest trying the candida diet, which involves eliminating gluten, sugar, and certain dairy products. However, there is little scientific evidence to prove that this can prevent an overgrowth of yeast fungi in the gut.
What Is Stomach Acid Made Of
Stomach acids low pH level is largely due to hydrochloric acid .
However, theres only a very small amount of HCl in stomach acid. Other components include potassium chloride and sodium chloride .
The cells lining your stomach wall secrete this acidic trio. The cells also release several enzymes and mucus.
This mucus is key to the process. It protects the lining of your stomach so that the acid and other gastric juices dont damage the sensitive organ.

What Are The Side Effects Of High Stomach Acid
Having high levels of stomach acid can increase your risk of developing other stomach-related health conditions. These include:
- Peptic ulcers:Peptic ulcers are sores that can develop when gastric acid begins to eat away at the lining of your stomach.
- Gastroesophageal reflux disease :GERD is a condition in which stomach acid backs up into your esophagus.
- Gastrointestinal bleeding: This involves bleeding anywhere in your digestive tract.
Hydrochloric Acid And Pepsin
Hydrochloric acid plays an important role in food digestion. The acid is made by parietal cells in the gastric glands. HCl does its job in the stomach cavity, or lumen. The parietal cells also secrete intrinsic factor, which is necessary in order for vitamin B12 to be absorbed in the small intestine.
Other cells in the gastric glands known as chief cells make a substance called pepsinogen. Hydrochloric acid converts pepsinogen into an enzyme called pepsin. Pepsin begins the digestion of protein in our food, breaking up the long, folded chains of amino acids into shorter and simpler structures. The enzyme requires an acidic environment to do its job. Enzymes in the small intestine complete the breakup of the protein molecules, allowing individual amino acids to enter the bloodstream.

Robin Warren & Barry Marshall
Interest in understanding the role of bacteria in stomach diseases was rekindled in the 1970s, with the visualization of bacteria in the stomach of gastric ulcer patients. The bacterium had also been observed in 1979 by Australian pathologist Robin Warren, who did further research on it with Australian physician Barry Marshall beginning in 1981. After numerous unsuccessful attempts at culturing the bacteria from the stomach, they finally succeeded in visualising colonies in 1982, when they unintentionally left their Petri dishes incubating for 5 days over the Easter weekend. In their original paper, Warren and Marshall contended that most stomach ulcers and gastritis were caused by infection by this bacterium and not by stress or spicy food, as had been assumed before.
Barry James Marshall, AC, FRS, FAA is an Australian physician, Nobel Prize laureate in Physiology or Medicine, and Professor of Clinical Microbiology at the University of Western Australia. Marshall is well-known for proving that the bacterium Helicobacter pylori is the cause of most peptic ulcers, reversing decades of medical doctrine which held that ulcers were caused by stress, spicy foods, and too much acid.
Gastric Acid Secretion And Intragastric Ph
Hydrochloric acid is the main component of gastric juice and is secreted by the parietal cells of the gastric mucosa in the fundus and corpus. In healthy adults, intragastric pH ranges between 1.5 and 2.5 in the fasting state. Intragastric nutrients are the most potent stimulators of gastric acid secretion however, due to dilution and buffering effects there is usually a transient rise in gastric pH postprandially to values between 4.5 and 6.0. Extent and duration of the rise in pH depend not only on meal properties but also on gastric-emptying velocity. Mean postprandial hydrochloric acid output is about 2030 mmol h1.

Contraindications For Hcl Acid Supplementation
HCl acid supplementation can prove to be extremely beneficial for a remarkably wide range of conditions, perhaps not surprisingly if it improves digestion. It is something that I have used in clinical practice for 18 years and still do. Below is a list of conditions in which HCl acid may be of help:
|Some conditions in which HCl acid may be of help
However, it is not for every patient. Whilst the vast majority of patients with stomach symptoms are candidates for HCl acid supplementation, not all can tolerate HCl, and it can elicit unpleasant heart burn symptoms, or even worse. This is rare, but it is definitely worth avoiding.
Start patients on a single supplement in the middle of their lunch, not dinner lest there is a problem that keeps them up all night, and have them gradually increase their dose to the desired level over a number of days. It may be best NOT to use HCl acid in the morning, when the bodys energy tends to be better and it is not needed so much.
I also recommend that you ask patients to complete on a 2 weekly basis the symptom questionnaire that relate to the low stomach acid, so that some form of monitoring can be in place. The use of HCl supplements is also a good example of why patients should NOT follow any supplement programme for more than a month or two without the specific recommendation of the practitioner.
Betaine HCl + Pepsin is still probably the most important supplement for digestion.

What Are The Four Protective Mechanisms Used To Protect The Stomach From Self
By secreting sticky, neutralizing mucus that adheres to the stomach walls, your stomach protects itself from being digested by its own enzymes or burned by the corrosive hydrochloric acid. The lining of your stomach produces a thin layer of mucus that helps protect it from the acids contained in your stomach juice. If you were to remove this protective layer, the acids would quickly destroy any material they came into contact with. The more acidic the environment, the thicker the layer of mucus becomes.
The four main defenses that prevent damage to the stomach lining are: mechanical protection provided by gastric juices chemical protection afforded by digestive enzymes barrier protection provided by the intestinal wall and immune surveillance performed by lymphatic vessels.
Mechanical protection is provided by gastric juices which contain hydrochloric acid and pepsin that digest proteins and polypeptides. These chemicals are necessary for breaking down food into nutrients that can be absorbed through the intestine. However not all particles found in food can be broken down using these chemicals some remain in the stomach where they cause irritation to the lining.
Chemical protection is afforded by digestive enzymes which exist in high concentrations in pancreas and small intestine.
What Protects The Stomach Wall
The mucosal barrier protects the stomach against self-digestion. This barrier is made up of multiple parts. Next, gastric glands produce and secrete more than 100 different proteins into the mucus layer.
Finally, immune cells called mast cells are present in the submucosa layer. These cells release chemical mediators that cause inflammation if they are activated. This allows the body to destroy harmful substances such as bacteria and other foreign objects that enter the stomach.
All of these components work together to protect the stomach against damage from acids, enzymes, and toxins in food. If any of these layers are removed or injured, acute gastrointestinal bleeding may result. However, over time these same layers prevent tissue damage by blocking the entry of digestive enzymes that would otherwise break down the stomach wall.
Many factors can lead to the failure of this protective mechanism and allow the stomach wall to be damaged. For example, medications such as proton pump inhibitors decrease the amount of acid in the stomach and have been shown to increase the risk of intestinal infection, stress fractures, and bone mineral loss. In addition, patients who suffer from cirrhosis of the liver may develop esophageal cancer due to lack of protection provided by healthy stomach tissue.

How Is Hydrochloric Acid Made In The Stomach
HCl is produced by the parietal cells of the stomach. To begin with, water and carbon dioxide combine within the parietal cell cytoplasm to produce carbonic acid , which is catalysed by carbonic anhydrase.

Impaired Gastric Acidification Negatively Affects Calcium Homeostasis And Bone Mass
Calcium deficiency in the elderly is associated with low gastric acid secretion and bone loss. A new study linking defects in gastric acid secretion with bone destruction and impaired mineralisation bolsters the view that calcium supplements can prevent these bone defects-but do they all work. This paper suggests that altered acidification of the stomach and specific gene deficiencies will dictate the form of calcium supplementation most suitable for the reduction and resolution of osteoporosis.
