Slide 2: Key Functions of Iron in Human Health Oxygen Transport Energy Production and Hemoglobin Synthesis

• Iron plays three vital physiological roles in human health. First, as the core component of hemoglobin, it enables oxygen transport in red blood cells.
• Second, iron is essential for mitochondrial function, supporting cellular energy production through electron transport chains.
• Finally, iron is irreplaceable for hemoglobin synthesis itself – without adequate iron, the bone marrow cannot produce functional red blood cells.
• visually emphasizes iron’s important roles through three circular illustrations: the first shows a red blood cell carrying oxygen molecules (O2); the second depicts a mitochondrion with ATP molecules, illustrating iron's involvement in mitochondrial function and energy metabolism; and the third portrays a red blood cell with numerous hemoglobin molecules (represented by circular structures).

Slide 3: Iron Absorption and Transport in the Body

• The body absorbs and processes iron through a tightly regulated sequence. Dietary iron exists in two forms: heme iron (Fe²⁺) from animal sources, and non-heme iron (Fe³⁺) from plant-based foods.
• In the duodenum, ferric reductase converts non-heme iron (Fe³⁺) to the absorbable ferrous form (Fe²⁺). This iron is then transported across enterocytes by divalent metal transporter-1 (DMT1).
• Inside cells, iron binds to ferritin for storage or couples with hephaestin for export into circulation. There, it attaches to transferrin – the transport protein that delivers iron to target tissues like bone marrow for hemoglobin synthesis.
• The slide employs a clear, sequential visual design, using a simplified anatomical illustration alongside magnified cellular processes and color-coded ions to explain the absorption of heme and non-heme iron from dietary sources through the digestive system into the bloodstream for transport and storage.

Slide 4: Iron Distribution in the Human Body Hemoglobin Storage

• In healthy adults, the body contains approximately 4 to 5 grams of iron, distributed across key systems. The majority – about 1,800 milligrams – is incorporated into red blood cells as hemoglobin, supporting oxygen transport. Another 1,000 milligrams is stored in the liver as ferritin, serving as a reserve. Recycled iron from aged red blood cells accounts for 600 milligrams within reticuloendothelial macrophages, while 300 milligrams supports ongoing hemoglobin production in the bone marrow.
• The slide uses a minimalist anatomical outline alongside bar graphs to visually represent the distribution of iron in healthy adults,

Slide 5: Iron Deficiency Anemia Defined Low Hemoglobin Levels and Diagnostic Thresholds by Gender

• Iron deficiency anemia is defined by abnormally low hemoglobin levels in red blood cells – the critical protein that carries oxygen throughout the body. Diagnostic thresholds vary by gender: hemoglobin levels below 12 grams per deciliter in women, or below 13 grams per deciliter in men, indicating anemia.
• The slide visually defines Iron Deficiency Anemia as a condition marked by reduced hemoglobin in red blood cells, symbolized by a red blood cell with a prominent white "X," and provides diagnostic hemoglobin thresholds for females and males using silhouette icons.

Slide 6: IDA as the Leading Cause of Anemia Worldwide with Global Prevalence Statistics

• Representing a significant global health burden, affecting approximately 25% of the world's population. Strikingly, half of all anemia cases worldwide – that is, 50% – are directly attributable to iron deficiency. These statistics underscore iron deficiency as the leading cause of anemia globally.
• The slide visually presents global statistics using a world map enclosed in a circle, overlaid with a red banner highlighting the percentage

Slide 7: High Risk Groups for Iron Deficiency Anemia

• Certain populations face elevated risks of developing iron deficiency anemia. Women of reproductive age are particularly vulnerable due to monthly blood loss during menstruation, significantly increasing their iron requirements."
• "Vegetarians and vegans may also be at risk unless they consciously incorporate plant-based iron sources and enhancers of iron absorption, as non-heme iron from plants is less bioavailable than heme iron from meat."
• "Infants and children—especially those experiencing growth spurts, or born prematurely or with low birth weight—have heightened iron needs to support development. Without adequate supplementation or iron-rich foods, they can quickly deplete their iron stores.
• This slide, identifies three key groups at higher risk: women, depicted with a downward "Fe" arrow signifying iron loss due to menstruation; vegetarians, shown with a woman eating a salad and multiple "Low Iron" labels; and infants & children, illustrated with children and a downward "Fe" arrow.

Slide 8: Section slide for IDA

• This section slide illustrates the connection of the condition to a common physical sign by displaying a pale hand alongside a magnified view of blood showing a reduced number of red blood cells

Slide 9: Stages of Iron Deficiency Anemia Depletion Impaired Production

• IDA progresses through three distinct stages, each marked by specific physiological changes."
• "In the first stage, iron stores become depleted, indicated by low serum ferritin, though hemoglobin levels and red blood cell production remain normal at this point."
• "The second stage occurs when the bone marrow begins producing red blood cells with insufficient hemoglobin, resulting in reduced mean corpuscular hemoglobin (MCH) on lab tests, even before anemia becomes apparent."
• "By the third stage, hemoglobin levels drop below normal thresholds, resulting in full iron deficiency anemia with microcytic, hypochromic red blood cells visible on peripheral smear."
• The slide illustrates the progression of the condition through three circular stages connected by arrows: the first stage shows low iron stores in the liver but normal red blood cells with adequate hemoglobin (Hb); the second stage depicts the bone marrow producing red blood cells with insufficient hemoglobin; and the third stage reveals mature red blood cells with significantly reduced hemoglobin levels.

Slide 10: Section Slide Causes and Pathogenesis

• The slide, under the title "Causes and Pathogenesis," visually represents the digestive system with a highlighted stomach and intestines, indicating the site where dietary iron ("Fe" symbol) is absorbed into the body.

Slide 11: Main Causes of Iron Deficiency Anemia

• Three principal causes Iron deficiency anemia, each disrupting iron balance through distinct mechanisms."
• "Insufficient dietary intake - particularly of bioavailable heme iron from meat, fish and poultry. Vegetarians and malnourished individuals are especially vulnerable as plant-based iron has lower absorption rates."
• "Increased physiological demand - most notably during pregnancy where iron requirements nearly double to support both expanded maternal blood volume and fetal development, often exceeding dietary intake capabilities."
• "Impaired intestinal absorption - seen in conditions like celiac disease, autoimmune gastritis, or post-bariatric surgery states where duodenal iron transport mechanisms are compromised, regardless of dietary intake.
• This slide outlines three primary causes: insufficient dietary intake, depicted by a woman eating a salad with a downward "Fe" arrow, highlighting vegetarians and malnourished individuals' vulnerability; increased physiological demand, illustrated by a pregnant woman, emphasising the higher iron requirements, shown with a digestive system diagram.

Slide 12: Gastrointestinal Disorders and Their Role in Iron Deficiency Anemia Blood Loss and Malabsorption

• Gastrointestinal disorders contribute significantly to iron-deficiency anemia through two primary mechanisms: chronic blood loss and malabsorption."
• "Inflammatory conditions like ulcerative colitis and Crohn's disease cause both intestinal bleeding and impaired iron absorption due to mucosal damage. Colon cancer similarly leads to occult blood loss that may go undetected."
• "Other pathologies such as intestinal infections and colon polyps can also produce chronic blood loss, gradually depleting iron stores even before anemia becomes clinically apparent.
• The slide connects gastrointestinal issues to iron deficiency by displaying a simplified digestive system alongside magnified cross-sections of the intestinal lining illustrating various disorders

Slide 13: Key Symptoms of Iron Deficiency Anemia

• Characteristic symptoms of IDA, all stemming from inadequate oxygen delivery."
• "Fatigue arises as the body struggles to produce sufficient hemoglobin for oxygen transport."
• "Pale skin develops when reduced hemoglobin levels diminish the normal redness of blood circulation."
• "Heart palpitations occur as the cardiovascular system compensates for diminished oxygen capacity."
• "Shortness of breath reflects the muscles' insufficient oxygen supply during exertion.
• visually presents four key symptoms alongside a central image of a woman with a circled and crossed-out "Fe" symbol: fatigue, depicted with a depleted battery icon; pale skin, shown with a light-colored hand; heart palpitations, illustrated with a racing heart; and shortness of breath, represented by a person struggling to breathe.

Slide 14: Serious Complications of Untreated Iron Deficiency Anemia

• Untreated iron deficiency anemia can lead to serious systemic complications across multiple organ systems."
• "Cardiac complications include tachycardia and arrhythmias as the heart strains to compensate for reduced oxygen delivery, potentially leading to heart failure in severe cases."
• "In pregnancy, severe anemia increases risks of preterm delivery by 2-fold and doubles the likelihood of low birth weight infants due to placental insufficiency."
• "For children, chronic deficiency impairs growth velocity and cognitive development, with potential long-term neurodevelopmental consequences.
• The slide outlines three significant complications: cardiac complications, illustrated by a woman with a racing heart, problems during pregnancy, depicted by a pregnant woman,; and growth problems, shown with a small baby labelled "low kg,”.

Slide 15: Diagnostic Approaches to Iron Deficiency Anemia

• Diagnosing iron deficiency anemia requires a systematic laboratory approach combining multiple tests."
• "The Complete Blood Count (CBC) provides initial screening, revealing microcytic hypochromic anemia through low hemoglobin and hematocrit values with reduced MCV and MCH."
• "Serum Ferritin serves as the most sensitive indicator of depleted iron stores, with levels below 30 nanoggrams/mL confirming deficiency."
• "Comprehensive Iron Studies evaluate transferrin saturation  and total iron-binding capacity (TIBC), while excluding other anemia types."
• "Folate Levels assessment helps differentiate mixed nutritional deficiencies, as folate is crucial for proper erythropoiesis.
• The slide visually outlines the diagnostic process for Iron Deficiency Anemia by presenting four key blood tests – Complete Blood Count showing microcytic hypochromic anemia, Serum Ferritin Test indicating low iron stores, comprehensive Iron Studies assessing various iron-related markers, and Folate Levels Test to exclude other anemias – each represented by a test tube and magnified blood sample.

Slide 16: Section Slide Managing Iron Deficiency Anemia

• Management employs targeted interventions based on severity and underlying cause.
• The slide depicts a hand holding a blood sample connected to two hanging bags of A+ blood for transfusion, illustrating a potential treatment strategy for Iron Deficiency Anemia (IDA).
• This is a Section Slide for the Management of IDA

Slide 17: Iron Deficiency Anemia Treatment Options

• "Intravenous iron rapidly replenishes stores, often requiring just 1-2 infusions for moderate cases, particularly when oral absorption is impaired."
• "Oral iron supplements remain first-line for most patients, though 3-6 months of therapy are typically needed to fully restore iron reserves and hemoglobin levels."
• "In severe symptomatic cases, blood transfusions provide immediate red cell mass improvement, while medications like erythropoiesis-stimulating agents may be adjunctively used to boost marrow production when inflammation complicates recovery.“
• The slide presents four treatment options: iron supplements, depicted as a bottle and tablets with an "Fe" symbol; intravenous iron, shown as an IV drip with an "Fe" symbol; medicines, illustrated as pills and a bottle with a medical cross; and blood transfusions, represented by a blood bag.

Slide 18: Preventing Iron Deficiency Anemia

• Preventing iron deficiency anemia involves a multi-faceted dietary approach."
• "Iron-rich foods form the foundation, including both heme iron sources like lean red meat and salmon, and non-heme options such as beans, dried fruits, and iron-fortified cereals."
• "Vitamin C co-consumption significantly enhances non-heme iron absorption - pairing iron-fortified bread with orange juice or adding strawberries to oatmeal can boost uptake by 2-3 fold."
• "For toddlers, introducing iron-dense solid foods like pureed meats and fortified cereals is critical during rapid growth phases to prevent developmental delays.
• The slide presents three key approaches to preventing iron deficiency: consuming iron-rich foods, depicted with images of meat, beans, and dried fruits alongside an "Fe" symbol; eating Vitamin C-rich foods, illustrated with an orange and strawberries with a "C" symbol; adequate iron intake for toddlers, shown with a child being fed.
