What Is Iron Deficiency?

Common Causes and Risk Factors

  • Chronic blood loss (heavy periods or stomach bleeding)
  • Low iron in your diet (or eating too much sugar, which blocks absorption)
  • Higher iron needs during pregnancy or teenage growth spurts
  • Digestive issues (like celiac disease or stomach ulcers)
  • Risk groups: women of childbearing age, young children, frequent blood donors

Signs and Symptoms

  • Tiredness or feeling weak
  • Pale skin or pale nails
  • Spoon-shaped or brittle nails
  • Shortness of breath when active
  • Dizziness or headaches
  • Cold hands and feet
  • Cravings for non-food items like ice or clay (pica)

How Dr. Rishi Chadha Diagnoses Iron Deficiency Anemia

Step-by-Step Diagnostic Approach:

Medical History & Physical Exam

Dr. Chadha reviews your symptoms�fatigue, weakness, pica (cravings for ice or clay), menstrual history, diet and any GI bleeding risks. A hands-on exam looks for pale skin, brittle or spoon-shaped nails, and other signs of anemia.

Blood Tests

Key labs include a complete blood count (CBC) to assess hemoglobin and red blood cell indices, serum ferritin to gauge iron stores, serum iron and total iron-binding capacity (TIBC). Together these pinpoint iron deficiency and its severity.

Stool Occult Blood Test

A non-invasive test that checks for hidden blood in the stool, helping identify GI blood loss as a potential cause.

Endoscopy & Colonoscopy (When Indicated)

  • Upper Endoscopy (EGD): Visualizes the esophagus, stomach and duodenum to detect ulcers, celiac disease or other bleeding lesions.
  • Colonoscopy: Examines the large intestine for polyps, diverticular bleeding or other sources of chronic blood loss.

Capsule Endoscopy (If Needed)

A swallowable camera capsule may be used to inspect the small bowel for obscure bleeding sources not reached by traditional scopes.

Through every step, Dr. Chadha explains findings and next steps in clear, patient-friendly language so you feel informed and confident in your care plan.

Frequently Asked Questions

What is the ICD-10 code for iron deficiency anemia?

D50.9 is the general code for iron deficiency anemia, unspecified. Other codes (D50.0�D50.8) specify particular causes.

How long does it take to fix iron deficiency?

Most people feel improvement in 4�8 weeks of treatment. Full recovery of iron stores can take 3�6 months.

Can sugar cause low iron?

Eating too much sugar can interfere with iron absorption, but it is not the only factor in iron deficiency.

Are there side effects from iron pills?

Some patients experience nausea or constipation. Taking supplements with food or switching formulations may help.

When is IV iron needed?

IV iron is recommended when oral supplements are not tolerated or fail to raise iron levels adequately.

How can I prevent iron deficiency anemia?

Maintain a diet rich in iron (meat, leafy greens, beans), pair it with vitamin C, and have regular blood tests.

What foods lower iron absorption?

Beverages and foods like tea, coffee, dairy products, and sugary snacks can inhibit iron uptake when consumed with meals.

Can anemia affect my nails?

Yes. Iron deficiency may cause brittle, ridged, or 'spoon-shaped� nails (koilonychia).

Can children have iron deficiency anemia?

Yes. Growing children can develop anemia from inadequate dietary intake or rapid growth spurts.
