Chronic inflammation in the colon (eg, ulcerative colitis)

High-fat diet, smoking, and obesity
Genetic syndromes such as familial adenomatous polyposis
Long-term use of certain medications (eg, steroids)
Signs and Symptoms
Often none in early stages; detected on routine exams
Blood in the stool or changes in bowel habits
Unexplained abdominal pain or cramping
Headaches, vision disturbances, or mood swings (pituitary)
High blood pressure, weight gain, or fatigue (adrenal)
Unintended weight loss or persistent weakness
How Dr. Nghia Nguyen Diagnoses Adenoma-Related?
Dr. Nguyen uses a step-by-step approach:
Medical History and Exam
He reviews your symptoms—epigastric pain, changes in appetite or bowel habits, weight shifts—and checks for family history of adenomas.
Endoscopy or Colonoscopy
He performs an upper endoscopy to examine the stomach lining or a colonoscopy to identify and biopsy any polyps or adenomas in the GI tract.
Imaging Studies
CT scan or MRI of the abdomen to spot adrenal or pancreatic adenomas contributing to pain.
Head MRI for suspected pituitary adenomas if hormone‐related symptoms arise.
Laboratory and Hormone Tests
Blood work checks hormone levels (cortisol, ACTH), liver and pancreatic enzymes, and rules out ulcerative colitis or other inflammatory causes.
ICD-10 Coding
He documents findings using codes like D35.2 for pituitary adenoma or relevant GI adenoma codes in your medical record.

Frequently Asked Questions
What's the difference between an adenoma and a carcinoma?
An adenoma is a benign (non-cancerous) tumor arising from gland tissue, while a carcinoma is a malignant (cancerous) tumor. Removing adenomas early helps prevent them from turning into cancer.
How is an adenoma found?
Adenomas are typically detected through imaging studies (CT, MRI), lab hormone tests, or during routine colonoscopies when polyps are identified and removed.
What is ICD-10 D35.2?
ICD-10 D35.2 is the diagnostic code used in medical records to classify pituitary adenomas.
Can food and exercise help?
Yes. A high-fiber diet, reduced red meat and processed foods, regular physical activity, and stress management can lower your risk and support recovery.
What's recovery like after surgery?
Most patients go home the same day after procedures like polypectomy or laparoscopic adrenalectomy and feel back to normal within one to two weeks.
Are adenomas cancer?
No, adenomas are benign tumors. However, if left untreated, some adenomas can develop into carcinoma over time.
What happens at my first visit?
Dr. Nguyen will review your health history, perform a focused exam, recommend appropriate tests or screenings, and outline a personalized care plan.
