What Is Abnormal Weight Loss?
Abnormal weight loss is defined as an unintentional loss of more than 5% of your body weight over six to twelve months. In medical coding, it's classified under ICD-10 code R63.4. If you haven't changed your diet or exercise routine but are still dropping pounds, it's important to seek a medical evaluation.
Local risk factors in Houston: smoking, poor diabetes control, prolonged stress

How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your weight‐loss timeline, epigastric pain characteristics (onset, location, triggers), dietary habits, medication use, travel history and other risk factors.
Laboratory Tests
CBC and metabolic panel to check for anemia, electrolyte imbalances and organ function.
Thyroid function tests and blood sugar levels to rule out endocrine causes.
Celiac serologies and inflammatory markers (CRP, ESR) for malabsorption or inflammation.
Stool studies (calprotectin, ova & parasites, fat quantification) to assess for infection or malabsorption.
Imaging and Endoscopic Evaluation
Abdominal ultrasound or CT scan to look for masses, organ enlargement or lymphadenopathy.
Upper endoscopy (EGD) to inspect the esophagus, stomach and duodenum for ulcers, gastritis, celiac changes or tumors-especially important for persistent epigastric pain.
Advanced Diagnostics (if needed)
If initial tests are inconclusive, he may recommend capsule endoscopy, small‐bowel biopsy or motility studies to detect subtle mucosal disease, strictures or dysmotility.
