Gastrointestinal Services

Gastroenterology is the branch of medicine focused on the digestive system and its disorders. This includes the esophagus, stomach, intestines, liver, pancreas, gallbladder, and other organs involved in processing food and eliminating waste. Gastroenterologists are specially trained to diagnose, treat, and manage conditions that affect these systems—helping patients improve digestion, absorb nutrients, and maintain overall digestive health.

Common Symptoms or Conditions Treated:

Acid Reflux & GERD
Acid Reflux:
Acid reflux occurs when stomach acid flows back up into the esophagus—the tube that connects your mouth to your stomach. This can cause a burning sensation in the chest known as heartburn, as well as symptoms like regurgitation, sore throat, or a bitter taste in the mouth. Occasional acid reflux is common and can be triggered by certain foods, overeating, or lying down after meals.
GERD (Gastroesophageal Reflux Disease):
GERD is a chronic and more severe form of acid reflux. It happens when acid reflux occurs frequently—usually two or more times a week—and causes persistent symptoms or complications. GERD can lead to inflammation of the esophagus, difficulty swallowing, chronic cough, or even damage to the esophageal lining over time.
Ulcers
Ulcers are open sores that develop on the lining of the stomach, small intestine, or esophagus. They occur when the protective lining of these areas is damaged, allowing stomach acid to cause irritation or erosion.
The most common type is the peptic ulcer, which includes:
  • Gastric ulcers – found in the stomach
  • Duodenal ulcers – found in the upper part of the small intestine (duodenum)
Causes of Ulcers:
  • Infection with Helicobacter pylori (H. pylori) – a common bacteria that can damage the stomach lining
  • Frequent use of NSAIDs – such as ibuprofen or aspirin
  • Excess stomach acid production
  • Smoking, stress, or alcohol use (can worsen symptoms but are not primary causes)
Common Symptoms:
  • Burning or gnawing pain in the stomach (often between meals or at night)
  • Bloating or nausea
  • Loss of appetite
  • In severe cases: vomiting blood or black, tarry stools
Treatment:
Ulcers are typically treated with medications that reduce stomach acid, antibiotics (if H. pylori is present), and lifestyle changes. Most ulcers heal with proper care, but untreated ulcers can lead to serious complications.
Irritable Bowel Syndrome (IBS)
Irritable Bowel Syndrome (IBS):
Irritable Bowel Syndrome (IBS) is a common, long-term condition that affects the large intestine (colon). It is a functional gastrointestinal disorder, meaning it causes symptoms without visible damage to the digestive tract.
Key Symptoms of IBS:
  • Abdominal pain or cramping
  • Bloating and gas
  • Changes in bowel habits, such as:
    • Diarrhea (IBS-D)
    • Constipation (IBS-C)
    • Or both alternating (IBS-M)
Causes and Triggers:
The exact cause of IBS isn’t fully understood, but it may involve:
  • Abnormal muscle contractions in the intestines
  • Increased sensitivity of the gut
  • Imbalances in gut bacteria
  • Stress and mental health issues
  • Certain foods or eating patterns
Important Notes:
  • IBS does not cause permanent damage to the intestines.
  • It does not increase the risk of colon cancer.
  • Symptoms can vary in severity and may come and go over time.
Management and Treatment:
While there is no cure for IBS, symptoms can often be managed through:
  • Dietary changes (e.g., low FODMAP diet)
  • Stress management
  • Medications (for pain, diarrhea, or constipation)
  • Lifestyle modifications

 

Hepatitis and Other Liver Disorders
Hepatitis:
Hepatitis refers to inflammation of the liver, most commonly caused by a viral infection. It can also result from excessive alcohol use, certain medications, toxins, or autoimmune conditions.
There are several types of viral hepatitis, including:
  • Hepatitis A – A short-term infection usually spread through contaminated food or water.
  • Hepatitis B – A virus spread through blood, sexual contact, or from mother to baby. It can be short-term or chronic.
  • Hepatitis C – A bloodborne virus that often leads to chronic liver disease if untreated.
  • Hepatitis D – Occurs only in people with hepatitis B infection.
  • Hepatitis E – A short-term illness spread mainly through contaminated water (common in developing countries).
Other Common Liver Disorders:
  • Fatty Liver Disease (Hepatic Steatosis):
    Buildup of fat in the liver. It may be caused by alcohol (Alcoholic Fatty Liver Disease) or other factors like obesity and diabetes (Non-Alcoholic Fatty Liver Disease – NAFLD).
    In severe cases, it can progress to non-alcoholic steatohepatitis (NASH) and lead to liver damage.
  • Cirrhosis:
    Scarring of the liver caused by long-term liver damage (often due to hepatitis, alcohol use, or fatty liver disease). It can lead to liver failure if not managed.
  • Liver Cancer:
    Can develop in people with chronic liver disease, especially cirrhosis. The most common type is hepatocellular carcinoma.
  • Autoimmune Hepatitis:
    A condition where the immune system attacks liver cells, causing inflammation and damage.
  • Hemochromatosis and Wilson’s Disease:
    Genetic conditions that cause the body to store too much iron or copper, leading to liver damage.
Symptoms of Liver Disorders May Include:
  • Fatigue
  • Yellowing of the skin or eyes (jaundice)
  • Abdominal pain or swelling
  • Nausea or loss of appetite
  • Dark urine or pale stools
Diagnosis and Treatment:
Liver disorders are typically diagnosed through blood tests, imaging, and sometimesliver biopsy. Treatment depends on the cause and may include:
  • Medications (e.g., antivirals for hepatitis)
  • Lifestyle changes (e.g., diet, avoiding alcohol)
  • In severe cases, liver transplant may be necessary.
Gallstones
Gallstones are hardened deposits that form in the gallbladder, a small organ located under the liver that stores bile—a fluid that helps digest fats. These stones can vary in size and number, and are made mostly of cholesterol or bilirubin.
What Causes Gallstones?
Gallstones develop when:
  • There is too much cholesterol or bilirubin in the bile
  • The gallbladder does not empty properly
  • Other factors such as obesity, certain medical conditions, or genetics increase risk
Symptoms of Gallstones:
Many people with gallstones have no symptoms. When symptoms occur, they may include:
  • Sudden, intense pain in the upper right abdomen or center of the stomach (often after eating fatty meals)
  • Nausea or vomiting
  • Pain that may spread to the back or right shoulder
  • Sometimes fever or jaundice if complications occur
Treatment:
Treatment depends on symptoms and may include:
  • Watchful waiting if no symptoms
  • Medications to dissolve stones (less common)
  • Surgery to remove the gallbladder (cholecystectomy) if stones cause pain or complications
Pancreatitis
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach that helps with digestion and blood sugar regulation by producing enzymes and hormones like insulin.
Types of Pancreatitis:
  • Acute pancreatitis: Sudden inflammation that lasts for a short time and often resolves with treatment.
  • Chronic pancreatitis: Long-lasting inflammation that leads to permanent damage and scarring of the pancreas.
Common Causes:
  • Gallstones blocking the pancreatic duct
  • Heavy alcohol use
  • Certain medications or infections
  • High levels of triglycerides in the blood
  • Trauma or surgery
Symptoms:
  • Severe upper abdominal pain that may radiate to the back
  • Nausea and vomiting
  • Fever and rapid pulse (in acute cases)
  • Weight loss and oily stools (in chronic cases)
Treatment:
Treatment depends on the severity and cause but often includes:
  • Hospitalization for acute cases with IV fluids and pain management
  • Addressing the underlying cause (e.g., gallstone removal, alcohol cessation)
  • Dietary changes and enzyme supplements for chronic pancreatitis
Constipation and Diarrhea
Constipation is a common condition where bowel movements become infrequent or difficult to pass. It often involves hard, dry stools and may cause discomfort, bloating, or a feeling of incomplete evacuation.
Common Causes:
  • Low fiber diet
  • Inadequate fluid intake
  • Lack of physical activity
  • Certain medications
  • Medical conditions affecting the digestive system
Diarrhea
Diarrhea is the condition of having frequent, loose, or watery bowel movements. It can lead to dehydration if it lasts a long time or is severe.
Common Causes:
  • Infections (viral, bacterial, or parasitic)
  • Food intolerances or allergies
  • Certain medications
  • Digestive disorders like IBS or inflammatory bowel disease

 

Colon Polyps and Colon Cancer Screening
Colon polyps are small growths that develop on the inner lining of the colon (large intestine). Most polyps are benign (non-cancerous), but some can develop into colon cancer over time if left untreated.
Types of Colon Polyps:
  • Hyperplastic polyps: Usually harmless and very common.
  • Adenomatous polyps (adenomas): These have the potential to become cancerous.
  • Inflammatory polyps: Often found in people with inflammatory bowel disease.
Symptoms:
Colon polyps usually do not cause symptoms, especially when small. Sometimes, larger polyps may cause:
  • Rectal bleeding
  • Changes in bowel habits
  • Abdominal pain (rare)
Detection and Treatment:
Colon polyps are often found during routine screening tests like a colonoscopy. If found, they are usually removed to prevent the risk of cancer.
