Everything You Need to Know About Anemia: Causes, Symptoms & Treatment

Introduction
Anemia is a most common blood disorder that affects millions of individuals across the globe. It happens when our body lacks sufficient healthy red blood cells to transport sufficient oxygen to our tissues. This results in fatigue, weakness, and a host of other health problems if not treated.
What is Anemia?
Anemia is a condition characterized by a decrease in hemoglobin content or the number of red blood cells in the body. Hemoglobin is the iron-containing protein found in red blood cells that carries oxygen from the lungs to the rest of the body. With low hemoglobin, your organs and tissues might not get sufficient oxygen to work effectively.
Types of Anemia
1. Iron-Deficiency Anemia
This happens when your body doesn't receive sufficient iron to make enough hemoglobin. It is caused by:
- Blood loss (e.g., heavy menstruation or ulcers)
- Diet lacking in iron-rich foods
- Malabsorption (e.g., celiac disease)
Symptoms: Weakness, pale complexion, shortness of breath, brittle fingernails.
2. Vitamin-Deficiency Anemia
This is also known as megaloblastic anemia, it happens due to a deficiency of vitamin B12 or folate. It could be caused by:
- Poor dietary intake
- Digestive disorders (e.g., Crohn's disease)
- Addiction of Alcohol
Symptoms: Fatigue, numbness in hands and feet, memory loss.
3. Aplastic Anemia
A serious as well as a rare disorder in which the body ceases to produce a sufficient number of red blood cells. Causes:
- Autoimmune diseases
- Toxic chemical exposure
- Certain drugs
- Viral infection
- Inherited Conditions
Symptoms: Fatigue, repeated infections, uncontrollable bleeding.
4. Hemolytic Anemia
This happens when blood cells are destroyed on a faster rate than the body can produce them or replace them and this leads to a lower RBC count. It may be:
- Hereditary (e.g., sickle cell anemia, thalassemia)
- Acquired (e.g., as a result of autoimmune disease)
Symptoms: Jaundice, dark urine, enlarged spleen.
5. Sickle Cell Anemia
A genetic disease in which red blood cells become sickle-shaped and destroy themselves easily, causing chronic anemia.
Symptoms: Pain crises, growth retardation, repeated infections.
What Are the Symptoms of Anemia?
Anemia symptoms vary from mild to severe, depending on the cause and degree. Some common symptoms are:
- Constant fatigue or tiredness
- Weakness
- Pale or yellow complexion
- Shortness of breath
- Irregular heartbeat
- Dizziness or lightheadedness
- Cold hands and feet
- Headaches
- Coughing up blood (in severe cases)
What Causes Anemia?
The causes of anemia are classified into three groups:
1. Blood Loss
- Heavy menstrual bleeding
- Gastrointestinal bleeding (ulcers, hemorrhoids, cancers)
- Surgery or trauma
2. Reduced or Defective Red Blood Cell Production
- Poor diet
- Chronic diseases (e.g., kidney disease, cancer)
- Genetic disorders (e.g., thalassemia)
3. Red Blood Cell Destruction
- Autoimmune diseases
- Sickle cell disease
- Infections
- Certain medications
Who Is at Risk of Anemia?
Some individuals are more prone to developing anemia, including:
- Women of childbearing age
- Pregnant women
- Infants and young children
- Older persons
- Individuals with chronic illness
- Low-iron diet vegetarians or vegans
- Individuals with gastrointestinal disease (e.g., IBS, Crohn's)
How Is Anemia Diagnosed?
Tests used to identify the cause and type of anemia:
Routine Tests:
- Complete Blood Count (CBC): Counts red blood cells, hemoglobin, and hematocrit.
- Reticulocyte Count: Evaluates bone marrow functioning.
- Iron Studies: Examines serum iron, ferritin, TIBC.
- Vitamin B12 and Folate Levels.
- Bone Marrow Examination (in exceptional cases).
Advanced Imaging (if required):
- Endoscopy
- Colonoscopy
- Ultrasound (for bleeding internally or tumors)
Anemia in Women and Children
Women
Women are particularly vulnerable to anemia as a result of menstrual blood loss and pregnancy. Prenatal care and iron supplements are crucial during pregnancy.
Children
Anemia in children is a common problem in countries like India. It has the potential to impair growth and development. Iron-fortified foods, routine pediatric visits, and multivitamin supplements are advised.
Treatment Options for Anemia
The treatment of Anemia is based on the cause and severity:
1. Changes in Diet and Lifestyle
- Iron-containing foods (spinach, red meat, lentils, fortified cereals).
- Folic acid and vitamin B12 supplements.
- Limiting tea and coffee with meals (they interfere with iron absorption).
2. Iron Supplements
- Oral iron capsules or tablets
- Intravenous (IV) iron for individuals with absorption problems or severe anemia
3. Vitamin Therapy
- B12 injections for people with absorption problems
- Folate supplements
4. Medications
- Erythropoietin (EPO) for chronic kidney disease anemia
- Immunosuppressants for autoimmune anemia
5. Blood Transfusions
Reserved for cases of severe or life-threatening anemia.
6. Bone Marrow Transplant
Bone Marrow transplant also known as Stem Cell Transplant, it is taken into very exceptional conditions such as aplastic anemia or specific genetic forms, where the condition is life-threatening.
Can Anemia Be Prevented?
Yes, in most cases, Anemia can be prevented, by taking some precautions and staying alert. Here are few things one can do :
- Eat a well-balanced diet: Incorporate iron, vitamin B12, folate, and vitamin C.
- Regular screenings: Particularly for high-risk populations.
- Treat underlying ailments: Control chronic diseases such as kidney diseases, cancer, or autoimmune disorders.
- Avoid excessive use of painkillers (NSAIDs): As they can lead to gastrointestinal bleeding.
Conclusion
Anemia may look normal, but it can be life-threatening if not treated properly. Early detection can make all the difference. If you notice any unusual symptoms, don’t ignore them seek medical help. With the right treatment and timely care, recovery is possible. At Neotia Getwel Multispecialty Hospital, we’re here to support you every step of the way.
