IRON DEFICIENCY ANEMIA.
Iron deficiency is the commonest nutritional deficiency globally. It simply refers to low levels of iron in your blood.
Iron in your blood is an important element for blood cell production and maintainance, and oxygen transport.
Research estimates that 24.8% of the global population have Anemia. Of this number, 42% are pregnant women, 30% are menstruating, and 47% are children under 5years.
The World Health Organization (WHO) estimates that about 50% of the 1.62billion cases of anemia result from iron deficiency.
SIGNS AND SYMPTOMS.
Signs of Iron Deficiency Anemia include:
Fatigue, light-headedness, shortness of breath, unusually cold hands and feet, fast heart beat, pale skin (visible on the palms in dark skinned people), hair loss, brittle nails, cravings for sand, ice or other non-food items.
DIAGNOSIS
Doctors usually check ferritin and transferrin (a protein that transports iron to all cells of the body) levels to rule out Iron deficiency as cause of anemia.
CAUSES & PEOPLE AT RISK.
Some of the causes and risk factors for Iron deficiency Anemia include:
📍Any condition that casues Blood loss, e.g in menstruating women, especially during heavy periods (a significant amount of iron is lost during heavy bleeds), bleeding from severe injuries like in an accident, people who have bleeding hemorrhoids or any disease that leads to stooling of blood.
📍Conditions that reduce the absorption of iron, e.g People with gastrointestinal conditions like celiac disease, crohn's disease, ulcerative colitis, or who have had any gastric surgeries.
📍Infants and young children, especially those born preterm or low birthweight. Their growth is rapid, so demand for iron is higher.
📍Pregnant women. Maternal blood cell production increases due to demand from the growing baby.
📍People who frequently donate blood. Usually the interval shouldn't be less than 8weeks.
📍Individuals with Heart Failure. Mostly due to poor nutrition and poor absorption.
📍Vegetarians and Vegans: People who do not eat any animal based foods.
📍People with Advanced kidney failure: The kidneys produce a hormone called ERYTHROPOIETIN which initiates the process for making new red blood cells.
However, in chronic kidney disease, the kidneys cannot make sufficient amounts of this hormone. Hence, red blood cell production significantly declines.
Also some blood is lost during haemodialysis sessions.
📍In athletes, especially Endurance athletes, red blood cells breakdown faster than they should, a condition known as "foot strike" hemolysis.
📍People who have Cancer.
📍Medications that inhibit stomach acid like proton pump inhibitors (e.g omeprazole), can reduce the absorption of iron in the gut.
🔸️Iron can reduce the absorption of Levodopa( a medication for parkinson's disease and restless leg syndrome). So take your iron supplements hours before or after levodopa.
TREATMENT.
🔹️Treatment is with iron supplements.
🔹️In severe cases an intravenous infusion of iron may be beneficial.
🔹️Your doctor may do some physical examinations and request for some tests to find the underlying cause, and treat it.
Very little iron is passed out in urine and stool. Most of it is either utilised or stored.
