When we hear about anaemia, it’s often linked to women, but men can also suffer from anaemia. Anaemia occurs when the body does not have enough healthy red blood cells to carry oxygen throughout the body. This leads to weakness, fatigue, and a variety of health problems.
While women face anaemia due to menstruation and pregnancy, men may develop it because of lifestyle factors, underlying illnesses, or nutrient deficiencies. Recognizing the causes and early signs can prevent serious complications.
What Causes Anaemia in Men?
Several factors can cause anaemia in men, ranging from nutritional deficiencies to underlying medical conditions. Below are the primary causes:

1. Iron Deficiency
Iron is essential for haemoglobin production. Iron deficiency is a leading cause of anaemia and can result from:
- Inadequate dietary intake: Diets low in iron-rich foods like red meat, spinach, or fortified cereals.
- Blood loss: Chronic bleeding from conditions like gastrointestinal ulcers, haemorrhoids, or colon cancer can deplete iron stores.
- Poor absorption: Diseases like celiac disease or inflammatory bowel disease (IBD) can impair iron absorption.
2. Vitamin Deficiencies
Deficiencies in vitamin B12 or folate can lead to megaloblastic anaemia, where red blood cells are abnormally large and dysfunctional. Causes include:
- Dietary shortages: Low intake of B12 (found in meat, eggs, and dairy) or folate (found in leafy greens and beans).
- Malabsorption: Conditions like pernicious anaemia prevent B12 absorption.
- Alcohol overuse: Excessive alcohol can interfere with folate metabolism.

3. Chronic Diseases
Chronic conditions can suppress red blood cell production, leading to anaemia of chronic disease. Common culprits include:
- Kidney disease: Kidneys produce erythropoietin, a hormone that stimulates red blood cell production. Kidney dysfunction reduces erythropoietin levels.
- Inflammatory conditions: Rheumatoid arthritis, lupus, or chronic infections can impair red blood cell production.
- Cancer: Certain cancers, especially those affecting bone marrow (e.g., leukaemia), can cause anaemia.
4. Blood Loss
Acute or chronic blood loss is a significant cause of anaemia in men. Sources include:
- Gastrointestinal bleeding: Ulcers, gastritis, or colorectal issues.
- Trauma or surgery: Significant blood loss from injuries or procedures.
- Frequent blood donations: Regular donations without adequate recovery time can deplete iron stores.
5. Bone Marrow Disorders
Disorders affecting the bone marrow, where red blood cells are produced, can cause anaemia. Examples include:
- Aplastic anaemia: A rare condition where the bone marrow stops producing enough blood cells.
- Myelodysplastic syndromes: Bone marrow produces defective blood cells.
6. Haemolytic Anaemia
In haemolytic anaemia, red blood cells are destroyed faster than they are produced. Causes include:
- Autoimmune disorders: The immune system attacks red blood cells.
- Genetic conditions: Sickle cell disease or thalassemia, though less common in men, can cause haemolysis.
- Infections or toxins: Certain infections or exposure to chemicals can destroy red blood cells.
Signs and Symptoms of Anaemia in Men
The symptoms of anaemia can vary in severity depending on its cause and the degree of red blood cell deficiency. Common signs include:
- Fatigue and weakness: Feeling constantly tired or lacking energy, even after rest.
- Pale skin: A noticeably paler complexion or pale nail beds and gums due to reduced haemoglobin.
- Shortness of breath: Difficulty breathing, especially during physical activity, as oxygen delivery is impaired.
- Dizziness or lightheadedness: Feeling faint or unsteady, particularly when standing up quickly.
- Rapid or irregular heartbeat: The heart works harder to compensate for low oxygen levels.
- Cold hands and feet: Poor circulation due to insufficient oxygen delivery.
- Chest pain: In severe cases, reduced oxygen to the heart can cause discomfort.
- Cognitive issues: Trouble concentrating or memory problems due to low oxygen in the brain.
Specific Symptoms in Men
Men may experience additional symptoms or notice certain signs more prominently:
- Reduced exercise tolerance: Difficulty maintaining physical performance or stamina during workouts.
- Erectile dysfunction: In some cases, reduced oxygen delivery or underlying chronic conditions can contribute to sexual health issues.
- Muscle cramps: Lack of oxygen to muscles can cause cramping or soreness.
Risk Factors for Men
Certain factors increase the likelihood of anaemia in men:
- Age: Older men are at higher risk due to chronic diseases or reduced nutrient absorption.
- Chronic conditions: Men with kidney disease, diabetes, or inflammatory disorders are more susceptible.
- Lifestyle: Poor diet, excessive alcohol consumption, or intense physical training without proper nutrition.
- Family history: Genetic conditions like thalassemia or sickle cell disease can increase risk.
Diagnosis and Next Steps
If you suspect anaemia, consult a healthcare provider. Diagnosis typically involves:
- Blood tests: Complete blood count (CBC) to measure haemoglobin, red blood cell count, and other parameters.
- Iron studies: To assess iron, ferritin, and transferrin levels.
- Additional tests: To identify underlying causes, such as endoscopy for gastrointestinal bleeding or bone marrow biopsy for rare disorders.
- Treatment depends on the cause:
- Iron or vitamin supplements: For deficiencies.
- Medications or procedures: To address chronic diseases or stop bleeding.
- Lifestyle changes: Improving diet or managing chronic conditions.
Prevention Tips
To reduce the risk of anaemia:
- Eat a balanced diet: Include iron-rich foods (red meat, lentils, spinach), vitamin B12 sources (fish, eggs), and folate-rich foods (broccoli, beans).
- Monitor chronic conditions: Regular check-ups for kidney, liver, or gastrointestinal health.
- Limit alcohol: Excessive alcohol can impair nutrient absorption.
- Stay active but balanced: Avoid overtraining without proper nutrition.
When to See a Doctor
Seek medical attention if you experience persistent fatigue, shortness of breath, or other symptoms listed above. Early diagnosis can prevent complications like heart strain or organ damage.
Conclusion
Anaemia in men is often overlooked but can have serious health implications. Understanding its causes—ranging from iron deficiency to chronic diseases—and recognizing symptoms like fatigue or pale skin is crucial for early intervention. By maintaining a healthy diet, monitoring chronic conditions, and seeking timely medical advice, men can manage or prevent anaemia effectively. If you’re experiencing symptoms, don’t hesitate to consult a healthcare professional for a thorough evaluation.
