Gastric juice is a thin, clear, practically colorless acidic fluid secreted by the gastric glands, which extend deep into the mucosa of the abdominal wall. It mainly contains digestive enzymes responsible for the chemical digestion of proteins. Gastric juice, secreted during food digestion, creates a semi-liquid mixture called chyme. The primary components of gastric juice include hydrochloric acid, pepsin, gastric contents, mucus, and water.
The gastric gland is located in the wall of the stomach, and the juice secreted from this gland is known as gastric juice or digestive juice.
Function of Gastric Juice:
-
HCl, present in gastric juice, creates an acidic environment in the stomach, destroys bacteria, and activates inactive enzymes.
-
The pepsin enzyme in gastric juice combines with HCl to convert proteins into peptones.
-
The renin enzyme in gastric juice converts milk protein (caseinogen) into casein.
-
Gastric juice helps protect the stomach wall.
Gastric Acid:
Gastric acid, also known as stomach acid, is primarily composed of hydrochloric acid (HCl) and is a key component of gastric juice. Gastric juice helps in the digestion of food. Gastric acid is made up of hydrochloric acid.
Too much gastric acid can cause:
GERD (Gastroesophageal Reflux Disease): When your stomach has too much acid, it can cause heartburn. After eating for some time, you may experience heartburn. Chest pain and difficulty swallowing are also symptoms of GERD.
Peptic Ulcer: Excess acid can erode the stomach lining, leading to ulcer formation.
Gastric Problems: Excessive gastric acid can increase gastric problems, causing symptoms like vomiting, nausea, indigestion, and abnormal pain.
Too little gastric acid can cause:
Infections: Low gastric acid levels can cause gastrointestinal infections and food poisoning. Insufficient acid reduces the stomach’s ability to kill harmful bacteria.
Malabsorption: Low acid levels can cause poor absorption of essential nutrients such as vitamin B12, iron, calcium, and magnesium.
Hypochlorhydria: Very low stomach acid impairs digestion and nutrient absorption.
Some tips if you have too much gastric acid in your stomach:
- Lifestyle Changes: Adopting a healthy lifestyle can help cure this problem.
- High Fiber Diet: Eating high fiber foods can be beneficial.
- Moderate Eating After Evening: Avoid eating too much food after evening.
- Breakfast: Do not skip your breakfast.
- Post-Meal Habits: Avoid lying down immediately after eating; walk for some time instead.
- Dietary Tips: Avoid spicy foods, fried foods, and alcohol.
- Consultation: If you experience persistent issues, consult a gastroenterologist.
Some tips if you have too little gastric acid in your stomach:
- Dietary Adjustments: Consume fermented foods, apple cider vinegar, and probiotic-rich foods.
- Supplements: Consider taking supplements, but seek advice from a specialist.
- Consultation: If symptoms persist, consult a gastroenterologist.
