How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He discusses your epigastric pain onset, location, quality, duration, aggravating or relieving factors, as well as your diet, medications, alcohol use and any associated symptoms such as nausea, vomiting, heartburn or weight loss.
Laboratory Tests
We check a complete blood count (CBC) to look for anemia, liver function tests, pancreatic enzymes (amylase/lipase), and non-invasive H. pylori testing if an ulcer is suspected.
Imaging and Endoscopy
Upper endoscopy (EGD) to directly visualize the esophagus, stomach and duodenum for gastritis, ulcers, reflux‐related changes or masses.
Abdominal ultrasound to assess gallbladder disease, biliary tract issues or pancreatic abnormalities.
Advanced Testing (if needed)
When initial tests are inconclusive, Dr. Scott may order a CT scan of the abdomen, gastric emptying study for gastroparesis or capsule endoscopy to evaluate the small intestine for obscure sources of pain or bleeding.
Treatment
Our Team offers a full range of care for anemia.
1. Lifestyle and Diet Modifications
Lean meats, poultry, and seafood to boost heme iron
Iron-rich plant foods like beans, lentils, and dark leafy greens
Iron-fortified cereals and whole grains
Pairing iron sources with vitamin C (citrus fruits, bell peppers) for better absorption
Avoiding tea or coffee at meals, which can inhibit iron uptake
2. Medications
Oral iron supplements (e.g., ferrous sulfate, ferrous gluconate) per national guidelines
Vitamin B12 therapy via tablets or injections for deficiency
Folic acid supplements to correct folate deficiency
3. Minimally Invasive or Advanced Procedures
Blood transfusion for rapid correction in severe cases
Endoscopy to locate and treat gastrointestinal bleeding (ulcers, polyps)
Capsule endoscopy to identify bleeding in the small intestine

Frequently Asked Questions
What is the ICD-10 code for iron deficiency anemia?
The ICD-10 code for iron deficiency anemia is D50.9.
Can I treat anemia with diet alone?
Mild anemia may improve with diet and supplements, but it's important to rule out bleeding or absorption issues before relying on diet alone.
How fast do iron pills work?
Many patients feel more energetic within two to four weeks, though full recovery of iron stores often takes two to three months.
When is a blood transfusion needed?
Transfusions are reserved for severe anemia when hemoglobin is very low or symptoms (like extreme weakness or shortness of breath) are life-threatening.
What tests confirm normocytic anemia?
A complete blood count (CBC) shows normal-sized red blood cells but low numbers; additional tests help identify the underlying cause.
Do I need a referral to see Dr. Scott?
No referral is required. You can call GastroDoxs directly to schedule an appointment with Dr. Scott.
Are there side effects with iron pills?
Some patients experience stomach upset or constipation. Dr. Scott will adjust your dose or suggest alternatives to minimize side effects.
