How Dr. Scott Diagnoses Acute Anemia Due to Blood Loss:
Dr. Scott uses a step-by-step approach:
Medical History and Exam
Dr. Scott will inquire about symptoms like fatigue, dizziness, shortness of breath, and paleness. He'll also ask about any history of heavy menstrual periods, gastrointestinal bleeding (e.g., ulcers, varices), or trauma. Lifestyle factors and risk behaviors will also be considered.
Blood Tests
Key blood tests include a Complete Blood Count (CBC) to check hemoglobin and hematocrit levels, as well as iron studies and serum ferritin to assess for iron deficiency. A reticulocyte count may also be performed to evaluate bone marrow response to blood loss.
Imaging and Endoscopy
If gastrointestinal bleeding is suspected, an upper endoscopy (EGD) may be performed to inspect the esophagus, stomach, and duodenum for ulcers or varices. A colonoscopy may be considered if lower GI bleeding is suspected.
Advanced Testing (if needed)
If internal bleeding is suspected, a CT scan or abdominal ultrasound may be used to locate the source of bleeding, such as an aneurysm or organ injury.
Treatment
Our Team offers a full range of care for acute anemia due to blood loss.
1. Lifestyle and Diet Modifications
Eat more iron-rich foods (meat, spinach, beans) to rebuild red blood cells
Add vitamin C (oranges, bell peppers) to boost iron absorption
Avoid NSAIDs and alcohol, which can worsen bleeding
Stay well-hydrated to support overall recovery
2. Medications
Oral or IV iron supplements to restore hemoglobin levels
Proton-pump inhibitors (PPIs) to help heal GI ulcers
Blood transfusions for severe blood loss anemia
Clotting agents for underlying bleeding disorders
3. Minimally Invasive or Advanced Procedures
Endoscopic hemostasis (clips, bands, thermal) to stop active bleeding
Polypectomy for removal of bleeding polyps
Capsule endoscopy to locate small intestine bleeds
Angioembolization to block a bleeding vessel when endoscopy isn't sufficient
