How Dr. Scott Diagnoses Gastric Ulcer
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He evaluates symptoms such as burning upper abdominal pain, nausea, bloating, or early satiety. He reviews risk factors including NSAID or aspirin use, alcohol intake, smoking, stress, and any history of ulcers or bleeding.
Upper Endoscopy (EGD)
A flexible endoscope is used to directly inspect the stomach lining. Dr. Scott identifies the presence, size, and location of ulcers, and takes biopsies to rule out infection or malignancy.
H. pylori Testing
Urea breath test detects active H. pylori infection by measuring labeled CO? in your breath after ingesting a test solution.
Stool antigen test confirms ongoing infection with high accuracy.
Biopsy during endoscopy may also be tested for H. pylori presence.
Blood Work
Lab tests may include a complete blood count (CBC) to check for anemia due to chronic or microscopic bleeding, and additional labs to rule out other potential causes of symptoms.
Imaging Studies (if needed)
Abdominal ultrasound to evaluate for alternative causes of upper abdominal pain such as gallbladder or liver issues.
CT scan may be ordered if complications like perforation, obstruction, or deep ulceration are suspected.
