Symptoms, Causes, and Treatment of Anemia | Low Hemoglobin

Anemia is a condition characterized by a low level of hemoglobin in the blood, affecting the body’s ability to transport oxygen effectively. Dr. Chandrakant Lahane, a Hematologist, Hemato-Oncologist, and Bone Marrow Transplant Physician at Sahyadri Super Specialty Hospital in Pune, explains the key aspects of anemia, including its symptoms, potential causes, and the treatment options available.

Hemoglobin levels vary by gender: in males, the normal range is typically between 13 to 15 g/dL, while in females, it ranges from 12 to 14 g/dL. If your hemoglobin level falls below these thresholds, it indicates the presence of anemia. Red blood cells (RBCs), which contain the protein hemoglobin, are responsible for transporting oxygen throughout the body.

Anemia can manifest through various symptoms, including:

• Dizziness or lightheadedness
• Irritability
• Fatigue or weakness
• Palpitations or a racing heartbeat
• Shortness of breath during physical activity

If you experience these symptoms, it may be indicative of anemia.

Anemia can primarily be categorized into three main causes:

1. Blood Loss: This can occur due to conditions such as gastrointestinal bleeding (e.g., from piles or fissures) or heavy menstrual bleeding in women.
2. Decreased Production of Hemoglobin: This may happen due to insufficient iron intake in the diet, leading to iron deficiency anemia. Other deficiencies, such as vitamin B12 or folate, can also result in anemia.

Increased Destruction of Red Blood Cells: In some cases, the body produces normal amounts of RBCs, but they are destroyed faster than they can be produced. This can happen in conditions like autoimmune hemolytic anemia or hereditary hemolytic anemia.

• Blood Loss: Often originates from the gastrointestinal tract. Conditions such as piles, fissures, or intestinal bleeding can lead to significant blood loss, resulting in anemia. In women, heavy menstrual cycles can also contribute to this condition.
• Bone Marrow Production Issues: A common cause of reduced hemoglobin production is iron deficiency. Inadequate intake of iron-rich foods can lead to this deficiency. Similarly, a lack of vitamin B12 or folate can cause anemia. Genetic conditions like sickle cell anemia or beta-thalassemia can also affect hemoglobin production.

RBC Destruction: If the body produces antibodies against its own RBCs, it can lead to autoimmune hemolytic anemia. Additionally, hereditary forms of hemolytic anemia may also result in anemia.

The treatment for anemia depends on its underlying cause:

• For Anemia Due to Blood Loss: If blood loss is due to piles or fissures, surgical intervention may be required. For gastrointestinal bleeding, consulting a gastroenterologist for procedures like endoscopy or colonoscopy may be necessary. If menstrual bleeding is excessive, a gynecologist’s opinion is essential for appropriate treatment.
• For Anemia from Bone Marrow Production Issues: In cases of iron deficiency anemia, dietary changes are crucial. A diet rich in iron, including green leafy vegetables, pulses, dates, and jaggery, is recommended. It’s essential to avoid consuming tea or coffee immediately after meals, as these beverages can hinder iron absorption.
• For Vitamin Deficiencies: If anemia is due to vitamin B12 deficiency, dietary sources of non-vegetarian food are necessary. For those who do not consume non-vegetarian foods, regular vitamin B12 injections may be required.
• For Hereditary Anemia: Conditions like beta-thalassemia major may require regular blood transfusions or potentially a bone marrow transplant. In contrast, beta-thalassemia minor often does not necessitate regular transfusions but requires monitoring of hemoglobin levels.

For Hemolytic Anemia: Treatment may involve immunosuppressive steroids or other antibody-mediated therapies, depending on the underlying cause.

In summary, anemia is a significant health condition that can arise from various causes, resulting in a range of symptoms. Understanding the underlying cause is crucial for effective treatment. If you suspect you may have anemia or have further questions regarding this condition, it is important to consult a healthcare professional for a proper diagnosis and treatment plan.
