WHY IT IS IMPORTANT TO TREAT STOMACH (10 TIPS)

 

Introduction to the Stomach

The stomach is a muscular, hollow, J-shaped organ in the digestive system located between the esophagus and the small intestine (specifically the duodenum).

Its main function is to store, mix, and chemically break down food into a semi-liquid mixture called chyme before it moves into the small intestine for nutrient absorption.

It is part of the upper gastrointestinal tract and plays a crucial role in both mechanical digestion (churning, mixing) and chemical digestion (enzymes, acid).

Average adult stomach capacity:

Empty: ~50 mL

After meal: ~1–1.5 liters

Max stretch: up to ~4 liters in some individuals

 Anatomical Structure

The stomach has several anatomical divisions:

Regions of the Stomach

1. Cardia – The area where the esophagus connects to the stomach; contains the lower esophageal sphincter (LES) to prevent acid reflux.

2. Fundus – Dome-shaped upper portion; often filled with swallowed air or gas.

3. Body (Corpus) – The main central region; the largest part of the stomach responsible for most of the mixing and secretion.

4. Antrum – Lower portion; grinds food and regulates its emptying into the small intestine.

5. Pylorus – Connects to the duodenum; contains the pyloric sphincter that controls the flow of chyme.

 Layers of the Stomach Wall

From the inside out, the stomach wall has four main layers:

 Mucosa

Innermost layer; contains glands and mucus-producing cells.

Divided into:

• Epithelium (simple columnar cells)
• Lamina propria (connective tissue with blood vessels & immune cells)
• Muscularis mucosae (thin smooth muscle layer)

 Submucosa

Connective tissue layer containing blood vessels, lymphatics, and the submucosal plexus (part of the enteric nervous system).

 Muscularis externa

Three smooth muscle layers:

• Inner oblique – unique to stomach; aids in churning food

• Middle circular – responsible for constrictions

• Outer longitudinal – shortens stomach length

 Serosa

Outermost layer; a visceral peritoneum covering.

 Histology and Cell Types

The mucosa of the stomach contains gastric pits leading to gastric glands. Different regions have different gland types:

 Cell Types

1. Mucous cells – Secrete protective mucus.

2. Parietal cells – Secrete hydrochloric acid (HCl) and intrinsic factor (for vitamin B12 absorption).

3. Chief cells – Produce pepsinogen (inactive precursor of pepsin).

4. Enteroendocrine cells – Release hormones (e.g., gastrin, somatostatin, histamine).

5. Stem cells – Regenerate gastric epithelium.

 Functions of the Stomach

 Mechanical Digestion

• Rhythmic contractions churn and mix food with gastric juices.
• Inner oblique muscles give extra churning power.

 Chemical Digestion

• HCl lowers pH (~1.5–3.5) to denature proteins, kill microbes, and activate pepsinogen.
• Pepsin begins protein breakdown into peptides.
• Lipase digests some fats (especially in infants).
• Gastric amylase (minor role) begins carbohydrate breakdown.

 Storage and Controlled Release

• Food stored in fundus and body before gradual release into duodenum.
• Pyloric sphincter regulates flow to avoid overwhelming intestines.

 Absorption

Minimal — water, alcohol, certain drugs (e.g., aspirin), and small molecules can be absorbed.

 Regulation of Gastric Activity

Neural Regulation

• Cephalic phase: Triggered by sight/smell/taste; vague nerve stimulates secretion.
• Gastric phase: Food in stomach stimulates stretch receptors and chemoreceptors → gastrin release.
• Intestinal phase: Duodenum controls gastric emptying via hormones (secretin, CCK).

 Hormonal Regulation

• Gastrin – Increases acid secretion & motility.
• Histamine – Stimulates parietal cells via H2 receptors.
• Somatostatin – Inhibits acid secretion.
• Secretin & CCK – Reduce gastric activity when chyme enters duodenum.

 Stomach Acid & Enzymes

 Hydrochloric Acid (HCl)

Produced by parietal cells via proton pumps.

Functions:

• Activates pepsinogen → pepsin.
• Denatures proteins.
• Kills pathogens.
• Provides optimal pH for enzymes.

 Enzymes

• Pepsin – Breaks proteins into peptides.
• Gastric lipase – Digests triglycerides into glycerol & fatty acids.
• Rennin (Chymosin) – In infants, curdles milk for better digestion.

Disorders of the Stomach

 Gastritis

Inflammation of the stomach lining.

Causes: H. pylori infection, alcohol, NSAIDs.

 Peptic Ulcers

Open sores in mucosa due to acid damage.

Commonly from H. pylori or NSAIDs.

Gastroesophageal Reflux Disease (GERD)

LES failure → acid reflux into esophagus.

Stomach Cancer

Often linked to H. pylori, smoking, high-salt diet.

Gastroparesis

Delayed gastric emptying; common in diabetes.

 Zollinger–Ellison Syndrome

Gastrin-secreting tumor → excessive acid production.

 Clinical & Surgical Relevance.

• Endoscopy: Visual examination of stomach.
• Gastrectomy: Surgical removal (partial or total).
• Bariatric surgery: Gastric bypass or sleeve to treat obesity.
• H. pylori tests: Urea breath test, biopsy.

The stomach lining renews itself every 3–5 days to protect from acid damage.

You have “gastric rugae” — folds that flatten as stomach fills.

Stress can affect stomach acid secretion.

In some animals (like cows), the “stomach” is multi-chambered — but humans have just one.

The major diseases that affect stomach

1.Infectious Diseases

These are caused by bacteria, viruses, or parasites that directly affect the stomach.

1.1. Helicobacter pylori (H. pylori) infection

Cause: Spiral-shaped bacteria that survive in stomach acid.

Effects: Chronic gastritis, peptic ulcers, increased stomach cancer risk.

Prevention:

• Wash hands with soap before eating
• Drink safe, clean water.
• Avoid sharing eating utensils with infected people.
• Properly wash fruits and vegetables.

1.2. Viral gastroenteritis (“stomach flu”)

Cause: Viruses like norovirus or rotavirus.

Effects: Vomiting, diarrhea, cramps, fever.

Prevention:

• Frequent handwashing.
• Avoid contaminated food and water.
• Disinfect surfaces during outbreaks.
• Vaccination for rotavirus (children).

1.3. Parasitic infections

Cause: Parasites like Giardia lamblia or certain worms.

Effects: Stomach pain, bloating, diarrhea.

Prevention:

• Drink boiled or treated water.
• Wash vegetables thoroughly.
• Avoid undercooked seafood or meat.

2. Inflammatory Conditions

2.1. Gastritis

Cause: H. pylori, alcohol, NSAIDs, stress, spicy foods.

Prevention:

• Limit alcohol and avoid excessive spicy/acidic foods.
• Avoid long-term use of NSAIDs without medical advice.
• Manage stress.
• Treat H. pylori early.

2.2. Peptic ulcers

Cause: H. pylori, NSAIDs, excess acid.

Prevention:

Avoid smoking and heavy alcohol use.

Limit NSAID use.

Eat balanced meals

3. Structural & Functional Problems

3.1. Gastroesophageal reflux disease (GERD)

Cause: Weak lower esophageal sphincter allowing acid to flow back into the esophagus.

Prevention:

• Avoid overeating.
• Don’t lie down right after eating.
• Limit caffeine, alcohol, and fatty foods.
• Maintain healthy weight.

4. Cancer & Tumor-Related

4.1. Stomach (gastric) cancer

Cause: H. pylori infection, smoking, high-salt diet, processed meats, family history.

Prevention:

Treat H. pylori.

Eat a diet rich in fruits & vegetables.

Limit smoked, salted, and processed foods.

Avoid tobacco and alcohol.

5. Other Stomach Issues

Food poisoning – Avoid by practicing food hygiene and safe cooking.

Dumping syndrome – Often after stomach surgery; prevent by adjusting eating habits.

Stress-related stomach issues – Manage stress with relaxation techniques.

 Best Foods and Fruits for the Stomach

• Chamomile tea – calms stomach lining, reduces stress-induced acid.
• Lean proteins (chicken, turkey, tofu, fish) – digest easily compared to fatty meats.

6. Immune-Boosting Fruits for Stomach Protection

These fruits prevent infections like H. pylori and aid healing:

• Kiwi – vitamin C, supports mucosal healing.
• Guava – high vitamin C + fiber, protects against gastritis.
• Oranges & citrus (in moderation) – support immunity (but too much may irritate acid reflux).
• Grapes – antioxidants, reduce inflammation.
• Pineapple – bromelain enzyme aids digestion, but limit if you have acid reflux.

7. Hydration and Stomach-Friendly Drinks

• Bone broth – healing, rich in amino acids for gut lining repair.

Foods to Avoid for Stomach Health

To keep the stomach healthy, limit or avoid:

• Excess alcohol (irritates mucosa, causes gastritis).
• Caffeine (coffee, energy drinks – can worsen reflux).
• Spicy and fried foods (trigger gastritis and reflux).
• Highly processed foods (chips, fast food – slow digestion).
• Carbonated drinks (bloating, reflux).
• Too much red meat (hard to digest).
