Anaemia

Gambaran keseluruhan

Anaemia is a condition where your blood has fewer red blood cells or less haemoglobin (the protein that carries oxygen) than normal. This means your body's organs and tissues don't get enough oxygen, which can make you feel tired and weak.

Yes, anaemia is very common. The World Health Organization estimates that about 24% of the world's population has anaemia. It affects people of all ages, but is more common in women, young children, and people with long-term illnesses.

Anaemia can affect anyone, but it is more common in women (especially during pregnancy), infants and young children, older adults, people with chronic conditions like kidney disease or inflammatory bowel disease, and those with a poor diet.

Punca

Punca utama

• Blood loss: Heavy periods, bleeding in the stomach or intestines, or injury.
• Not enough red blood cell production: This can happen due to a lack of iron, vitamin B12, or folate in the diet, or due to bone marrow problems.
• Increased destruction of red blood cells: Conditions like sickle cell disease or autoimmune disorders.

Faktor risiko

• A diet low in iron, vitamin B12, or folate
• Heavy menstrual periods
• Pregnancy and childbirth
• Chronic diseases like kidney disease, cancer, or rheumatoid arthritis
• Family history of inherited anaemia (like sickle cell or thalassemia)
• Digestive problems that affect nutrient absorption (like celiac disease or after weight loss surgery)

Bila perlu berjumpa doktor

Jumpa doktor dengan segera jika:

• If you have chest pain, trouble breathing, or feel like you might faint, call your local emergency number immediately.
• If you notice blood in your stools or vomit, seek urgent care.

Buat temujanji rutin jika:

• If you have been feeling tired for weeks without a clear reason
• If you have heavy periods or other signs of blood loss
• If you have a family history of anaemia and are feeling unwell

Diagnosis

A doctor will ask about your symptoms, medical history, and family history. They will also do a physical exam and order blood tests.

Ujian yang mungkin dilakukan

• Complete blood count (CBC): This shows the number and size of your red blood cells and your haemoglobin level.
• Iron studies: To check if you have low iron stores.
• Vitamin B12 and folate levels: To see if you lack these vitamins.
• Other tests: Depending on the suspected cause, you may have tests for bleeding, bone marrow, or inherited disorders.

Apa yang diharapkan semasa temujanji anda

Diagnosis usually involves a simple blood draw. Sometimes you might need more tests like a stool test or an endoscopy (a camera test to look inside your digestive system). Your doctor will explain each step and what it means.

Rawatan

Treatment for anaemia depends on the cause. The goal is to increase your red blood cell count and improve symptoms. Common approaches include dietary changes, supplements, and treating the underlying condition.

Penjagaan diri di rumah

• Eat iron-rich foods like lean meat, beans, leafy greens, and fortified cereals.
• Include vitamin C (like citrus fruits) to help your body absorb iron.
• If you are low in B12, include eggs, dairy, or fortified plant milks.
• Avoid drinking tea or coffee with meals as they can reduce iron absorption.

Rawatan perubatan

If dietary changes are not enough, your doctor may recommend supplements (like iron, B12, or folate). For severe anaemia or certain types (like sickle cell anaemia), treatments may include injections, medications that help your body make more red blood cells, or blood transfusions. Always follow your doctor's advice and do not take supplements without a prescription.

Bila pembedahan dipertimbangkan?

Surgery is rarely needed for anaemia. However, if the cause is severe blood loss (e.g., from a bleeding ulcer or tumour), you may need a procedure to stop the bleeding.

Hidup dengan keadaan ini

Most people with anaemia can manage their condition well with treatment. You may need to pace yourself when you feel tired, and make sure you get enough rest. Keep follow-up appointments with your doctor to monitor your levels.

Tip gaya hidup

• Eat a balanced diet with plenty of iron, B12, and folate.
• Stay active but listen to your body – rest when you need to.
• Manage stress with relaxation techniques like deep breathing or gentle exercise.
• Avoid smoking and limit alcohol, as they can worsen anaemia.

Diet dan senaman

A healthy diet is key. Include foods rich in iron (red meat, spinach, lentils), vitamin C (oranges, bell peppers), and B12 (fish, eggs, fortified cereals). Gentle exercise like walking or yoga can help boost your energy, but do not push yourself if you feel weak.

Kesihatan mental dan kesejahteraan emosi

Living with chronic fatigue can be frustrating and may affect your mood. It is normal to feel down at times. Talk to your doctor if you feel anxious or depressed – they can offer support or refer you to a counsellor. Remember, treatment often improves both your energy and your emotional well-being.

Pencegahan

Some types of anaemia can be prevented by eating a balanced diet and managing health conditions. Iron-deficiency anaemia, for example, is often preventable with good nutrition. However, some inherited types cannot be prevented.

Program saringan

If you are at higher risk (e.g., pregnant women, young children, people with chronic diseases), your doctor may recommend regular blood tests to check for anaemia early.

Komplikasi

Jika tidak dirawat

• Severe fatigue that affects daily life
• Increased risk of infections
• Heart problems, including an enlarged heart or heart failure (from the heart working harder to pump oxygen-rich blood)
• In pregnancy: increased risk of premature birth or low birth weight
• In children: slower growth and development

Pandangan jangka panjang

With proper treatment, most types of anaemia improve significantly. Even chronic forms can be managed so that you can live a full and active life. The key is to work with your doctor to find the right treatment for you.
