Study Notes
Definition and Types
- Anemia is a medical condition characterized by a decrease in the number of red blood cells or the amount of hemoglobin in the blood.
- There are several types of anemia, including:
- Iron-deficiency anemia: caused by a lack of iron in the diet
- Vitamin-deficiency anemia: caused by a lack of vitamin B12 or folate
- Anemia of chronic disease: caused by chronic inflammation or infection
- Aplastic anemia: caused by the failure of the bone marrow to produce blood cells
- Hemolytic anemia: caused by the destruction of red blood cells
Causes and Risk Factors
- Causes:
- Blood loss (e.g. from surgery or injury)
- Chronic disease (e.g. kidney disease, cancer)
- Poor diet or malnutrition
- Inherited disorders (e.g. sickle cell anemia)
- Chronic inflammation or infection
- Risk factors:
- Women of childbearing age
- Pregnant women
- Infants and young children
- People with chronic diseases
- Vegetarians and vegans (due to limited iron intake)
Symptoms
- Fatigue and weakness
- Shortness of breath
- Dizziness or lightheadedness
- Pale skin
- Headaches
- Cold hands and feet
- Poor concentration
Diagnosis
- Complete Blood Count (CBC) to measure hemoglobin and red blood cell count
- Blood tests to measure iron, vitamin B12, and folate levels
- Physical examination to check for signs of anemia (e.g. pale skin, jaundice)
Treatment
- Iron supplements or dietary changes to increase iron intake
- Vitamin supplements or injections to treat vitamin deficiencies
- Blood transfusions in severe cases
- Medications to treat underlying conditions (e.g. chronic disease, inflammation)
- Bone marrow transplantation in severe cases of aplastic anemia
Definition and Types of Anemia
- Anemia is a medical condition characterized by a decrease in red blood cells or hemoglobin in the blood.
- There are several types of anemia, including iron-deficiency, vitamin-deficiency, anemia of chronic disease, aplastic anemia, and hemolytic anemia.
Causes of Anemia
- Blood loss, e.g. from surgery or injury, can cause anemia.
- Chronic diseases, e.g. kidney disease, cancer, can cause anemia.
- Poor diet or malnutrition can lead to anemia.
- Inherited disorders, e.g. sickle cell anemia, can cause anemia.
- Chronic inflammation or infection can cause anemia.
Risk Factors for Anemia
- Women of childbearing age are at risk of anemia.
- Pregnant women are at risk of anemia.
- Infants and young children are at risk of anemia.
- People with chronic diseases are at risk of anemia.
- Vegetarians and vegans are at risk of anemia due to limited iron intake.
Symptoms of Anemia
- Fatigue and weakness are common symptoms of anemia.
- Shortness of breath is a symptom of anemia.
- Dizziness or lightheadedness can occur in anemia.
- Pale skin is a symptom of anemia.
- Headaches can occur in anemia.
- Cold hands and feet are a symptom of anemia.
- Poor concentration is a symptom of anemia.
Diagnosis of Anemia
- Complete Blood Count (CBC) is used to diagnose anemia.
- Blood tests measure iron, vitamin B12, and folate levels.
- Physical examination checks for signs of anemia, e.g. pale skin, jaundice.
Treatment of Anemia
- Iron supplements or dietary changes can increase iron intake.
- Vitamin supplements or injections can treat vitamin deficiencies.
- Blood transfusions are used in severe cases of anemia.
- Medications can treat underlying conditions, e.g. chronic disease, inflammation.
- Bone marrow transplantation is used in severe cases of aplastic anemia.
