Increased gastric acidity

Increased gastric acidity
acidic environment of the stomach caused by the presence of hydrochloric acid, which activates the enzyme pepsin, causing the breakdown of food and denaturation of proteins larger peptides.Increased gastric acidity - less than 1.5 units.on an empty stomach.

What is the norm for the acidity of the stomach

Hydrochloric acid is isolated parietal cells, most of which are located in the upper part of the stomach (cardiac part of the body).

Normal gastric acidity (pH) on an empty stomach is 1.6-2 units (7 units -. A neutral environment).In other words, when it is less than 1.5 pH fasting talk about acidity of the stomach (hyperacidity states).As regulated

acidity in the stomach gastric acidity during the day varies widely.It depends entirely on the meals (eating phase) and is regulated by reflex.

  1. Brain phase when a person thinks about food, sees it or smells, the stomach begins to stand out in hydrochloric acid.This is a reflex, when the impact on visual or olfactory centers of the cerebral cortex
    is transmitted through the vagus nerve gastric parietal cells.The acidity of the stomach rises.
  2. Gastric phase when food enters the stomach, it causes local excitation of receptors, in response to which is allocated acid.
  3. Intestinal phase leaving the stomach, the food irritates receptors gatekeeper, the excitation of which inhibits acid production.

As there is an increased acidity of the stomach

Situational (transient) increased acidity of the stomach occurs in response to the excitement of the nervous system (stress) and the use of poorly chewed, fatty, fried, spicy, salty, hot food, alcohol, coffee, with overeating andet al.

If stress becomes chronic and local irritating factors are regularly present in food, increased acidity of the stomach becomes chronic, and the risk of acid diseases (gastritis, ulcers, GERD, etc.) is increased.

Infection with Helicobacter Pylori is not necessary, but sufficient for the development of gastric hyperacidity.

How to determine the acidity of the stomach

Increased gastric acidity does not always need a laboratory confirmation.Typically, medical history and clinical data for diagnostic giperatsidnyh enough states.

In doubtful cases, appoint intragastric pH meter.Fractional sensing stomach and determine the pH of gastric juice for urine is not used because of the large uncertainties techniques.

Symptoms of gastric hyperacidity

Situational increased acidity of the stomach is not clinically evident or noteworthy.Healthy mucous membrane of the stomach, esophagus and duodenum successfully resist single giperatsidnym attacks.

dyspeptic symptoms (various gastric pain, heartburn, belching, etc.) Occur when the acidity of the stomach leads to acid disorders.So do not allow long-term violations of diet and excessive nerve loads that initially occur without apparent clinical symptoms.
