gastric contents is associated with a diminution in the frequency of occurrence of lactic acid. In the hypo- secretory groups lactic acid was

What stimulates gastric juice release?
The three stimulants of gastric acid secretion likely to have physiological roles in regulation of secretion are
acetylcholine, gastrin, and histamine
. Acetylcholine is released by vagal and intramucosal reflex stimulation, acting directly on the parietal cell.
What lactic acid does?
Lactic acid, or lactate, is
a chemical byproduct of anaerobic respiration
— the process by which cells produce energy without oxygen around. Bacteria produce it in yogurt and our guts. Lactic acid is also in our blood, where it’s deposited by muscle and red blood cells.
Which will stimulate gastric acid secretion?
Gastrin
is a hormone produced by the stomach, which stimulates the release of gastric acid.
What is gastric juice function?
Gastric juice is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. Its main function is
to inactivate swallowed microorganisms
, thereby inhibiting infectious agents from reaching the intestine.
How is gastric juice collected?
Gastric fluid analysis, medical procedure used to examine the secretions and other liquid substances occurring in the stomach. By means
of a tube passed through the nose and into the stomach
, gastric fluid can be obtained from the stomach.
What are the symptoms of too much acid in your stomach?
- abdominal discomfort, which may be worse on an empty stomach.
- nausea or vomiting.
- bloating.
- heartburn.
- diarrhea.
- decreased appetite.
- unexplained weight loss.
What is the most important digestive enzyme in the stomach?
Pepsin
is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen.
What time of day is stomach acid the highest?
Acid secretion is highly variable from night to night, yet peaks in a circadian fashion
between 10 pm and 2 am
, suggesting a circadian component ( Figure 1).
What happens if you have too much lactic acid?
Lactic acid buildup can result in
muscle pain, cramps, and muscular fatigue
. These symptoms are typical during strenuous exercise and are not usually anything to worry about as the liver breaks down any excess lactate.
What happens when your lactic acid is high?
Higher-than-normal lactic acid levels can lead to a condition called lactic acidosis. If it’s severe enough, it can upset your body’s pH balance, which indicates the level of acid in your blood. Lactic acidosis can lead to these symptoms:
muscle weakness
.
How is high lactic acid treated?
Increasing oxygen to the tissues and giving IV fluids
are often used to reduce lactic acid levels. Lactic acidosis caused by exercising can be treated at home. Stopping what you’re doing to hydrate and rest, often helps.
What causes the stomach to produce too much acid?
Zollinger-Ellison syndrome is a rare condition in which one or more tumors form in your pancreas or the upper part of your small intestine (duodenum). These tumors, called gastrinomas, secrete large amounts of the
hormone gastrin
, which causes your stomach to produce too much acid.
Which hormone stops acid secretion in the stomach?
The
hormone somatostatin
stops the release of stomach acid.
What triggers gastric acid production?
Acid secretion is initiated by food: the
thought, smell, or taste of food effects vagal stimulation of the gastrin-secreting G cells
located in the distal one third (antrum) of the stomach. The arrival of protein to the stomach further stimulates gastrin output.
