Overview
The gallbladder, pancreas, and liver are three essential organs that work together to support digestion, nutrient absorption, and metabolic function. The liver produces bile, which is stored in the gallbladder and released into the small intestine to help digest fats. The pancreas produces digestive enzymes and the hormones insulin and glucagon to regulate blood sugar. Diseases affecting any of these organs can have significant impacts on overall health and quality of life.
Gallbladder Disease
Gallstones (Cholelithiasis)
Gallstones are hardened deposits of bile that form in the gallbladder. They range in size from a grain of sand to a golf ball and affect approximately 10 to 15% of adults in the United States. Many gallstones cause no symptoms (silent gallstones), but when a stone blocks a bile duct, it can cause:
- Biliary colic: Sudden, intense pain in the upper right abdomen or center of the abdomen, often after a fatty meal, lasting 30 minutes to several hours
- Nausea and vomiting
- Pain radiating to the right shoulder blade or back
Risk factors include female sex, age over 40, obesity, rapid weight loss, pregnancy, family history, diabetes, and certain ethnic backgrounds (Native American and Hispanic populations have higher prevalence).
Cholecystitis
Acute cholecystitis is inflammation of the gallbladder, usually caused by a gallstone obstructing the cystic duct. Symptoms include persistent right upper quadrant pain, fever, and tenderness with a positive Murphy's sign. This condition typically requires hospitalization and surgical removal of the gallbladder (cholecystectomy).
Choledocholithiasis
When gallstones migrate into the common bile duct, they can cause jaundice, cholangitis (infection of the bile duct), and pancreatitis. This condition often requires endoscopic retrograde cholangiopancreatography (ERCP) to remove the stones from the bile duct.
Pancreatic Disease
Acute Pancreatitis
Acute pancreatitis is sudden inflammation of the pancreas that can range from mild to life-threatening. The two most common causes are gallstones (blocking the pancreatic duct) and alcohol use. Symptoms include:
- Severe upper abdominal pain: Often radiating to the back, worse after eating
- Nausea and vomiting
- Fever and rapid pulse
- Abdominal tenderness and distension
Diagnosis involves elevated serum lipase (three or more times the upper limit of normal), characteristic abdominal pain, and confirmatory imaging (CT scan) when needed. Treatment includes bowel rest, intravenous fluids, pain management, and addressing the underlying cause.
Chronic Pancreatitis
Chronic pancreatitis is progressive, irreversible inflammation of the pancreas that leads to permanent structural damage. The most common cause is long-term heavy alcohol use. Over time, the pancreas loses its ability to produce digestive enzymes and insulin, leading to:
- Chronic abdominal pain: The most debilitating symptom
- Exocrine insufficiency: Maldigestion of fats causing steatorrhea (oily, foul-smelling stools), weight loss, and nutritional deficiencies
- Endocrine insufficiency: Diabetes mellitus (pancreatogenic diabetes, or type 3c)
Management includes pain control, pancreatic enzyme replacement therapy (PERT), dietary modifications (low-fat diet, small frequent meals), fat-soluble vitamin supplementation (A, D, E, K), and diabetes management.
Pancreatic Cysts
Pancreatic cysts are fluid-filled sacs found in or on the pancreas, increasingly detected incidentally on imaging. While many are benign, some types — particularly intraductal papillary mucinous neoplasms (IPMNs) and mucinous cystic neoplasms (MCNs) — carry a risk of malignant transformation. Dr. Khan follows established guidelines for surveillance and management of pancreatic cysts.
Liver Disease
Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)
Formerly known as non-alcoholic fatty liver disease (NAFLD), MASLD is the most common liver disease worldwide, affecting approximately 25 to 30% of adults. It is characterized by excess fat accumulation in the liver in patients with metabolic risk factors such as obesity, type 2 diabetes, high cholesterol, and metabolic syndrome.
MASLD encompasses a spectrum of disease:
- Simple steatosis: Fat in the liver without significant inflammation — generally benign
- Metabolic dysfunction-associated steatohepatitis (MASH): Formerly NASH — fat plus inflammation and liver cell damage, which can progress to fibrosis
- Fibrosis and cirrhosis: Progressive scarring that can lead to liver failure and hepatocellular carcinoma
FibroScan is an invaluable non-invasive tool for assessing liver fat content (CAP score) and fibrosis stage (stiffness measurement) in MASLD patients. Treatment focuses on lifestyle modifications including weight loss (7 to 10% body weight reduction can reverse steatohepatitis), exercise, and management of metabolic comorbidities. Resmetirom (Rezdiffra) is the first FDA-approved medication specifically for MASH with moderate to advanced fibrosis.
Alcohol-Associated Liver Disease
Chronic excessive alcohol consumption can cause a spectrum of liver injury including fatty liver, alcoholic hepatitis, and cirrhosis. Alcohol-associated hepatitis can be a severe, life-threatening condition requiring hospitalization. The cornerstone of treatment is complete alcohol abstinence, along with nutritional support and, in severe cases, corticosteroid therapy.
Cirrhosis
Cirrhosis represents the end stage of chronic liver disease from any cause, characterized by extensive fibrosis (scarring) that replaces normal liver tissue and impairs liver function. Complications of cirrhosis include:
- Portal hypertension: Increased pressure in the portal vein leading to varices (enlarged veins in the esophagus and stomach that can rupture and bleed)
- Ascites: Fluid accumulation in the abdomen
- Hepatic encephalopathy: Confusion and cognitive impairment due to toxin buildup
- Hepatorenal syndrome: Kidney failure in the setting of advanced liver disease
- Hepatocellular carcinoma: Liver cancer, for which cirrhosis patients require surveillance every 6 months
Diagnosis
Dr. Khan employs a comprehensive diagnostic approach for gallbladder, pancreas, and liver diseases:
- Blood tests: Liver function panel (AST, ALT, alkaline phosphatase, bilirubin, albumin), lipase and amylase, complete metabolic panel, and specialized tests (autoimmune markers, viral hepatitis panels, iron studies, ceruloplasmin)
- Abdominal ultrasound: First-line imaging for gallstones, liver steatosis, and liver masses
- FibroScan: Non-invasive assessment of liver fibrosis and steatosis — available in our office
- CT scan and MRI/MRCP: Detailed imaging for pancreatic disease, bile duct evaluation, and liver lesion characterization
- Endoscopic ultrasound (EUS): High-resolution imaging and biopsy capability for pancreatic masses, cysts, and bile duct stones
- ERCP: Both diagnostic and therapeutic for bile duct and pancreatic duct disorders
When to See a Doctor
Seek evaluation from a gastroenterologist if you experience:
- Recurrent upper abdominal pain, particularly after eating fatty foods
- Jaundice (yellowing of the skin or eyes)
- Unexplained weight loss or persistent nausea
- Dark urine or pale-colored stools
- Elevated liver enzymes on routine blood work
- Known risk factors for liver disease (obesity, diabetes, heavy alcohol use, viral hepatitis)
- Abdominal swelling or fluid retention
- A family history of pancreatic or liver disease
- An incidentally discovered pancreatic cyst or liver lesion on imaging
