  • Lipase
  • Mucin
  • Intrinsic factor
  • Peptides
  • Nucleic acids and
  • Electrolytes

Furthermore, they may contain saliva from swallowing, bile from gastroduodenal reflux, inflammatory mediators, or even blood from damaged stomach walls.

The amount of gastric juice produced per day is likely to be between 3 and 4 liters. The hydrochloric acid in gastric juice breaks down the food. At the same time, digestive enzymes break down the proteins.

Acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective layer. This, along with bicarbonate, ensures that the stomach wall itself isn’t damaged by hydrochloric acid.

Stomach acid is highly acidic. It has to be must be highly acidic for it to break down everything from meat to tough, fibrous plants.
The stomach acid breaks down food to make digestion easier. Meaning, that while your digestive system moves food through, your body becomes more capable of absorbing nutrients faster.

Normal stomach acid levels don’t cause illness or health complications to your body, because your stomach is designed to deal with it.
Acidity levels in your stomach can sometimes fluctuate. Gastric juices that are too high or too low can sometimes cause problems.

What Does Stomach Acid Look Like?

Basically, stomach acid or gastric juice is a watery, colorless fluid produced by the lining of the stomach. Gastric juices are usually in their normal state clear in color.

Endoscopies reveal that gastric juice is clear. The mucus of the esophagus (stomach) looks yellow and somewhat similar to nasal mucus.
In case of vomiting, you may see green or yellowish stuff that you threw up. This is usually bile vomited from the duodenum. This is extremely bitter. Bile does not come from the stomach.

Understanding how acid is measured in liquids will help you understand stomach acid’s strength. pH is a measure of acidity. A pH reading is between 0 and 14. Acid levels in fluids are stronger at lower pH levels and weak at higher PH levels. I am sure now can guess what is the pH level of water. The pH level of water is 7 a midpoint of 0 to 14.

pH Level of stomach acid
Stomach Acid pH Level

Here are a few examples for you to understand easily:

  • Battery acid – It has a pH of 0. Battery acids are extremely potent.
  • Water – pH level of water is 7. It is a natural liquid.
  • Alkaline – Seawater, Baking soda, bleaches pH levels from 8 to 13.

A stomach acid’s pH reading is between 1-2 – Highly Acidic

A stomach acid’s pH is between 1-2. It is quite acidic. In fact, battery acid is capable of dissolving materials such as metals and bones. In the case of stomach acid, with its pH level, just one or two spots higher can be deadly. It is good enough to damage the strongest materials, like bones and teeth.

Medical professionals use a range of methods to test for stomach acidity levels. These methods are designed to assess the stomach’s acidity levels.

There is nothing abnormal about your stomach acid’s acidic level fluctuating from time to time.
This essential fluid can be harmed by certain situations, like medications. These can hinder your body from producing HCI as much as it should.

Symptoms of low hydrochloric acid levels in the stomach include:

  • Gastric outlet obstruction
  • In some cases stopping medications to lower stomach acid

  • abdominal discomfort
  • weight loss


Causes of high hydrochloric acid levels in the stomach include:

  • High-stress levels
  • Aging and mostly over 65

  • Zinc deficiencies

  • Chronic illness

How to Treat High Hydrochloric Acid Levels

This requires treatments with medication. The doctor may suggest to got for Proton pump inhibitors (PPIs) to help reduce the hydrochloric acid levels in your stomach. On top of that depending on the condition they may include dietary changes, antibiotics, and in some cases surgeries.
