Hereditary Pancreatitis

Hereditary pancreatitis, a genetic disorder from PRSS1, SPINK1 or CFTR mutations, causes recurrent pancreatic inflammation. In Houston, Dr. Nghia Nguyen delivers expert, comprehensive diagnosis, advanced treatments, and long-term lifestyle support—helping patients reduce flare-ups, manage symptoms, and maintain optimal pancreatic function.

About the Expert

Dr. Nghia Nguyen, DO, is a board-certified gastroenterologist providing advanced digestive care in the Greater Houston area. He earned his medical degree from the Texas College of Osteopathic Medicine and completed both his Internal Medicine residency and Gastroenterology fellowship at the University of Texas at Rio Grande Valley. Dr. Nguyen specializes in treating conditions such as acid reflux, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and liver disorders.

Common Causes and Risk Factors

  • Family history of pancreatitis or known genetic mutations
  • Mutations in PRSS1, SPINK1, or CFTR genes
  • Smoking, which can worsen flare-ups
  • Heavy alcohol use
  • ICD-10 code K86.1 designates hereditary pancreatitis

Signs and Symptoms

  • Severe pain in the upper abdomen
  • Nausea and vomiting during attacks
  • Unexplained weight loss
  • Oily or fatty stools (steatorrhea)
  • Onset of diabetes over time

How Dr. Nghia Nguyen Diagnoses Hereditary Pancreatitis?

Dr. Nguyen uses a step-by-step approach:

Medical History and Physical Exam

She reviews your personal and family history of pancreatitis or related gene changes, then palpates the abdomen for epigastric tenderness or guarding.

Blood Tests

We measure pancreatic enzymes (amylase, lipase) to confirm inflammation, check liver function, and rule out other causes of abdominal pain.

Genetic Testing

Targeted panels identify mutations in PRSS1, SPINK1, or CFTR to establish a hereditary basis for your pancreatitis.

Imaging Studies

  • MRI/MRCP - detailed views of the pancreatic ducts, detecting strictures, stones, or inflammation.
  • CT scan - assesses acute flare-up severity, calcifications, and structural changes.
  • Abdominal ultrasound - initial screening for enlargement, fluid collections, or stones.

Advanced Diagnostics (if needed)

Endoscopic ultrasound provides high-resolution images, allows for fine-needle aspiration, and can guide therapeutic interventions.

  • Have small, frequent meals to reduce pancreatic strain
  • Receive support for smoking cessation and alcohol avoidance

2. Medications

  • Pancreatic enzyme replacement therapy to aid digestion
  • Pain management starting with mild analgesics and progressing as needed
  • Insulin therapy if diabetes develops

3. Minimally Invasive or Advanced Procedures

  • Endoscopic interventions to clear blocked pancreatic ducts

Frequently Asked Questions

What is the life expectancy with hereditary pancreatitis?

Repeated flare-ups can shorten life, but early care slows damage and helps you live better.

What is the hereditary pancreatitis ICD 10 code?

It is K86.1 for chronic pancreatitis caused by genetics.

Is pancreatic cancer inherited?

Hereditary pancreatitis may raise cancer risk over time, but pancreatic cancer is usually not passed down.

Do I need genetic testing?

Yes. It finds the exact gene change and helps Dr. Nguyen plan your care.

Can lifestyle changes cure hereditary pancreatitis?

No. Lifestyle and diet help reduce flare-ups but do not change your genes.

When should I see a specialist?

See a doctor if you have repeated belly pain, digestion problems, or lose weight without reason.
