All You Need to Know About Anaemia!


Anemia is a medical condition characterized by a low level of red blood cells in the body. This condition can have various causes, symptoms, and complications. In this comprehensive guide, we will delve into the different types of anemia, explore the risk factors and symptoms, discuss the importance of nutrition in managing anemia, and provide an overview of the diagnostic and treatment options available.

What Causes Anemia?

Anemia can occur due to factors that either decrease red blood cell production or increase red blood cell destruction or loss. Factors that decrease red blood cell production include inadequate dietary intake of essential nutrients such as iron, vitamin B12, or folate. Other causes include kidney disease, certain types of cancer, autoimmune diseases like lupus or rheumatoid arthritis, infections such as HIV or tuberculosis, and certain medications or treatments like chemotherapy or radiation therapy.

On the other hand, factors that increase red blood cell destruction or loss can include blood loss due to accidents, injuries, heavy menstrual bleeding, or gastrointestinal lesions. Hemolysis, which is the premature breakdown of red blood cells, can occur due to autoimmune activity, certain infections, medication side effects, or exposure to toxins. Inherited conditions like sickle cell disease, glucose-6-phosphate dehydrogenase (G6PD) deficiency, thalassemia, and hereditary spherocytosis can also lead to increased red blood cell destruction.

Risk Factors for Anemia

Certain factors increase the risk of anemia, including insufficient intake of iron, folate, or vitamin B12, menstruation, pregnancy, age over 65, gastrointestinal disorders like Crohn's disease or celiac disease, chronic health conditions such as cancer or kidney disease, family history of genetic anemia, certain medications, chemotherapy, radiation therapy, heavy alcohol consumption, and exposure to toxic chemicals.

Symptoms of Anemia

Symptoms vary in severity and cause, including fatigue, weakness, dizziness, headache, shortness of breath, pale skin, gums, or nails, cold extremities, rapid heartbeat, chest pain, fainting, brittle nails, tongue inflammation, mouth corner cracks, jaundice, heart murmurs, enlarged lymph nodes, spleen or liver, concentration difficulties, and unusual cravings. Seek medical attention, especially for fainting or chest pain.

Types of Anemia

Types include iron-deficiency, vitamin-deficiency (folate, vitamin B12), hemolytic, aplastic, and anemia of inflammation or chronic disease. Iron-deficiency is common due to insufficient iron for red blood cell production. Vitamin-deficiency results from low folate or B12 levels. Hemolytic involves rapid red cell destruction. Aplastic is inadequate bone marrow production. Chronic disease-induced anemia stems from inflammation affecting red cell production.

Daily Nutritional Requirements and Anemia

Adequate nutrition is vital. Iron and folate needs vary by age and sex. Men aged 19-50 require 8mg daily, while women need 18mg due to menstruation and pregnancy. Over 50, both sexes require 8mg. Folate intake should be 400mcg for adults, 600mcg for pregnant, and 500mcg for breastfeeding women. Vitamin B12 intake is 2.4mcg for adults. Sources include liver, red meats, seafood, fortified cereals, lentils, spinach, beans, and dairy.

Diagnosis of Anemia

Diagnosis involves medical history, physical exam, and blood tests like CBC, reticulocyte count, iron levels, ferritin, B12, folic acid, Coombs, fecal occult blood, and bone marrow tests based on suspicion.

Complications of Anemia

Untreated anemia can lead to heart issues, nerve damage, restless leg syndrome, depression, memory/concentration problems, weakened immunity, pregnancy complications, developmental delays, and multi-organ failure. Seeking medical help is crucial to prevent complications.

Treatment and Prognosis for Anemia

Treatment depends on the cause and severity and may include dietary changes, supplements, medications, transfusions, and managing underlying conditions. Regular monitoring ensures effective management. Prognosis varies; with proper treatment, many cases improve, restoring red cell levels and overall health.


In conclusion, anemia is a prevalent condition with significant health implications. Recognizing its types, understanding symptoms, and addressing nutritional needs are vital for effective management. Timely diagnosis and treatment can improve quality of life and reduce complications. If you suspect anemia, consult a healthcare professional for evaluation.
