GASTROENTROLOGY

Gastroenterology is the branch of medicine focused on the digestive system and its disorders. It deals with everything from the esophagus to the stomach, intestines, liver, gallbladder, and pancreas.

🦠 What Gastroenterologists Treat

They diagnose and manage conditions involving:

Esophagus (e.g. acid reflux, swallowing disorders)

Stomach (e.g. ulcers, gastritis)

Small and large intestines (e.g. IBS, Crohn's disease, ulcerative colitis)

Liver (e.g. hepatitis, fatty liver disease, cirrhosis)

Pancreas (e.g. pancreatitis)

Gallbladder (e.g. gallstones)

Rectum and anus (e.g. hemorrhoids, anal fissures)

🍽️ Common Gastrointestinal (GI) Conditions

GERD (Acid Reflux)

Stomach acid flows into the esophagus, causing heartburn and discomfort.

Peptic Ulcers

Sores in the stomach or duodenum lining, often caused by H. pylori or NSAIDs.

Irritable Bowel Syndrome (IBS)

A functional gut disorder causing cramps, bloating, diarrhea or constipation.

Inflammatory Bowel Disease (IBD)

Includes Crohn’s disease and ulcerative colitis, which involve chronic inflammation of the digestive tract.

Celiac Disease

An autoimmune reaction to gluten damaging the small intestine lining.

Liver Disease

Includes hepatitis, fatty liver disease, cirrhosis, and liver cancer.

Gallstones

Solid deposits in the gallbladder that may block bile flow.

Pancreatitis

Inflammation of the pancreas, which can be acute or chronic.

Colon Cancer

Often detected via colonoscopy; early detection is key.

Constipation & Diarrhea

Common but sometimes symptoms of a larger issue needing medical attention.

🧪 Diagnostic Tools Used in Gastroenterology

Endoscopy (viewing the upper GI tract)

Colonoscopy (examining the large intestine)

Ultrasound / CT / MRI

Liver function tests

Stool tests

Capsule endoscopy (swallowing a tiny camera)

🥗 Maintaining Digestive Health

Eat a high-fiber diet

Stay hydrated

Limit alcohol and caffeine

Avoid processed foods and excessive sugar

Exercise regularly

Manage stress

Get screened (especially for colon cancer after age 45 or earlier if high risk)
