Fatigue that won’t go away. Shortness of breath from climbing just a few stairs. Cold hands and pale skin. These are more than just signs of stress or a sleepless night — they could be your body’s way of crying out for oxygen. One of the most common causes? Anaemia.
According to vetlanda.hu, anaemia is far more than just “low iron.” It’s a condition that affects oxygen delivery throughout the body and, if left untreated, can seriously impact your overall health. Let’s take a closer look at what anaemia really is, why it matters, and how to recognize and manage it.
What Is Anaemia?
Anaemia is a condition in which the body doesn’t have enough healthy red blood cells or haemoglobin to carry adequate oxygen to the tissues. Since oxygen is essential for every cell’s function, its lack can cause widespread fatigue, weakness, and other systemic symptoms.
Haemoglobin is the iron-rich protein inside red blood cells that binds to oxygen in the lungs and delivers it to the rest of the body. When haemoglobin levels are too low, organs and tissues are deprived of oxygen, and the body’s performance suffers — sometimes silently, sometimes severely.
What Causes Anaemia?
Anaemia can result from several underlying issues, and identifying the cause is crucial for effective treatment. The most common causes include:
-
Iron deficiency: The most frequent type of anaemia worldwide. It can result from poor diet, blood loss (e.g. heavy menstruation, ulcers), or poor absorption (as in celiac disease).
-
Vitamin deficiency: Lack of vitamin B12 or folic acid can lead to megaloblastic anaemia, where red blood cells are abnormally large and don’t function properly.
-
Chronic diseases: Conditions such as kidney disease, cancer, or autoimmune disorders can suppress red blood cell production.
-
Bone marrow disorders: Diseases like leukaemia or aplastic anaemia affect the production of blood cells.
-
Genetic conditions: Sickle cell anaemia and thalassemia are inherited forms that affect the shape and function of red blood cells.
In many cases, more than one factor may be involved, particularly in older adults or those with chronic illnesses.
Common Symptoms of Anaemia
Anaemia can develop slowly, making its symptoms easy to ignore at first. However, as the condition worsens, the signs become more noticeable. Key symptoms include:
-
Persistent fatigue and weakness
-
Pale or yellowish skin
-
Dizziness or lightheadedness
-
Shortness of breath, especially during exertion
-
Rapid or irregular heartbeat
-
Cold hands and feet
-
Headaches
-
Difficulty concentrating
In severe or prolonged cases, anaemia can also lead to heart complications, including an enlarged heart or heart failure due to the increased workload on the circulatory system.
Who Is at Risk?
Anaemia can affect anyone, but certain groups are more vulnerable:
-
Women of childbearing age (due to menstruation and pregnancy-related demands)
-
Infants and children, especially those on restricted diets
-
Older adults, who may have chronic health conditions or poor nutrition
-
Vegetarians and vegans, if they don’t consume enough iron-rich plant foods or supplements
-
People with chronic diseases, including kidney disease, cancer, or inflammatory disorders
-
Individuals with gastrointestinal conditions, such as ulcers, celiac disease, or Crohn’s disease
Understanding your personal risk can help you be proactive in screening and prevention.
How Is Anaemia Diagnosed?
Anaemia is usually diagnosed through a complete blood count (CBC), which measures levels of red blood cells, haemoglobin, and haematocrit (the proportion of blood composed of red cells). Additional tests may include:
-
Iron studies (serum ferritin, transferrin saturation)
-
Vitamin B12 and folate levels
-
Reticulocyte count (to assess bone marrow function)
-
Stool tests (to detect hidden blood loss)
-
Bone marrow biopsy (in complex or unresponsive cases)
Accurate diagnosis is key, since treatment depends on the cause.
How Is Anaemia Treated?
Treatment of anaemia focuses on correcting the underlying cause and replenishing what the body lacks. Options may include:
-
Iron supplements: For iron deficiency anaemia; best absorbed on an empty stomach and often paired with vitamin C.
-
Vitamin B12 or folate: Injections or high-dose tablets may be necessary if absorption is impaired.
-
Dietary changes: Incorporating iron-rich foods (like red meat, lentils, spinach), or B12 sources (meat, eggs, dairy).
-
Addressing underlying diseases: Such as treating kidney problems, infections, or inflammatory conditions.
-
Blood transfusions: In severe or acute anaemia cases.
-
Erythropoietin-stimulating agents: Sometimes used in chronic kidney disease to promote red blood cell production.
Ongoing monitoring through blood tests ensures that the chosen treatment is effective and sustainable.
Preventing Anaemia: What You Can Do
While not all forms of anaemia are preventable, many are — especially those caused by diet or lifestyle. Here are some tips:
-
Eat a balanced diet rich in iron, B12, and folate
-
Pair iron-rich foods with vitamin C to enhance absorption
-
Avoid drinking tea or coffee with meals, as they inhibit iron absorption
-
If you’re at risk, consider regular blood tests and nutritional supplements
-
Treat chronic illnesses proactively to reduce their impact on red blood cell production
-
For women with heavy periods, consult a doctor about iron support
When to See a Doctor
If you’re feeling unusually tired, notice changes in your skin tone or heartbeat, or experience shortness of breath doing activities you used to manage easily, don’t ignore the symptoms. Anaemia may seem minor, but left untreated, it can lead to serious health consequences.
Early detection is crucial — and often, simple treatments can restore your vitality and quality of life.
Final Thoughts
Anaemia is more than just being “a bit low on iron.” It’s a condition that signals your body isn’t getting the oxygen it needs to function at full capacity. With proper awareness, diagnosis, and treatment, it’s entirely manageable — and often reversible.
So listen to your body. If it’s crying out for oxygen, it’s time to take action.
