Anaemia is a widespread blood condition that affects millions of people around the world, causing fatigue and weakness when the body doesn’t have enough healthy red blood cells to carry oxygen. While this condition can range from mild to severe, understanding how it can be managed through both established medical approaches and emerging therapies offers hope for better quality of life and improved outcomes for those living with it.

Understanding How Anaemia Treatment Works

The main goal of treating anaemia is to restore the body’s ability to carry oxygen effectively to all tissues and organs. This means increasing the number of healthy red blood cells, which are the cells responsible for picking up oxygen in the lungs and delivering it throughout the body. When someone has anaemia, their organs don’t get enough oxygen, leading to symptoms like tiredness, shortness of breath, dizziness, and headaches that can significantly impact daily activities.^[1]

Treatment choices depend heavily on what type of anaemia a person has and what caused it in the first place. Some people have anaemia because their diet lacks certain nutrients like iron or vitamins. Others lose blood through injury, surgery, or medical conditions like ulcers. Some inherit genetic conditions that affect how their red blood cells form or function. Still others develop anaemia because of chronic diseases like kidney problems or cancer.^[2]

The severity of anaemia also matters when planning treatment. Mild cases might need only dietary changes and supplements, while moderate to severe cases could require medications that stimulate red blood cell production or even blood transfusions. Healthcare providers use blood tests to measure hemoglobin, the iron-rich protein inside red blood cells that actually carries the oxygen. This measurement helps them understand how serious the anaemia is and track whether treatment is working.^[3]

Medical societies and healthcare organizations have established guidelines that recommend different treatments based on the underlying cause. For example, iron-deficiency anaemia is treated very differently from anaemia caused by kidney disease or autoimmune conditions. This is why finding the specific cause is so important—it allows doctors to choose treatments that address the root problem rather than just masking symptoms.^[4]

Around the world, anaemia remains a major public health concern, particularly affecting children, pregnant women, and people living in lower-income countries. Globally, about 40% of children aged 6 to 59 months, 37% of pregnant women, and 30% of women of reproductive age are affected by this condition. The burden is especially heavy in Africa and South-East Asia.^[5]

Standard Treatment Approaches for Anaemia

The most common form of anaemia worldwide is iron-deficiency anaemia, and its standard treatment centers on replacing the missing iron in the body. Doctors typically prescribe iron supplements in tablet form, which patients need to take for about six months to restore their iron levels to normal. These tablets work best when taken on an empty stomach, about one hour before or two hours after meals, though some people need to take them with food to avoid stomach upset.^[11]

Iron tablets can cause side effects that some patients find bothersome. These include constipation, diarrhea, stomach pain, nausea, and dark or greenish stools. Healthcare providers usually advise patients to drink plenty of fluids and eat foods rich in fiber to help manage these effects. Taking the tablets with orange juice or other foods high in vitamin C can help the body absorb the iron more effectively. However, patients should avoid taking iron supplements at the same time as antacids, milk, coffee, tea, or cola drinks, as these can interfere with iron absorption.^[14]

For people whose bodies have trouble absorbing iron from tablets, or those who cannot tolerate the side effects, doctors may recommend injectable iron. This form of iron is given through a vein and bypasses the digestive system entirely. It can be especially helpful for patients with inflammatory bowel disease or those who have had gastric bypass surgery, as these conditions can make it hard for the body to absorb nutrients from food.^[12]

When anaemia is caused by vitamin deficiencies rather than iron lack, the treatment approach changes accordingly. Vitamin B12 deficiency is often treated with intramuscular injections of the vitamin, particularly when the problem stems from the body’s inability to absorb B12 from food. This can happen in a condition called pernicious anaemia, where the immune system interferes with B12 absorption. At first, patients might need frequent shots, and some people require ongoing injections throughout their lives to keep their B12 levels normal.^[11]

Folic acid deficiency is treated with oral folic acid supplements along with dietary changes to include more folate-rich foods. This is particularly important for pregnant women, as folate plays a crucial role in preventing birth defects.^[4]

For severe cases of anaemia where the hemoglobin drops to dangerously low levels, blood transfusions become necessary. This is a common and generally safe medical procedure where healthy blood from volunteer donors is given through an intravenous line. The transfused blood quickly replaces what the patient is missing, providing immediate relief from severe symptoms and preventing complications like heart failure that can occur when oxygen levels in the body become critically low.^[12]

People with chronic kidney disease often develop anaemia because their kidneys don’t produce enough of a hormone called erythropoietin, which signals the bone marrow to make new red blood cells. For these patients, doctors may prescribe synthetic versions of this hormone, known as erythropoiesis-stimulating agents. These medications are given by injection and help the body produce more red blood cells on its own.^[4]

When anaemia results from an autoimmune condition where the body’s immune system attacks its own red blood cells, treatment may involve medications that suppress the immune system. Corticosteroids are often used for this purpose, as they can reduce inflammation and stop the immune system from destroying red blood cells.^[16]

For certain hereditary conditions like hereditary spherocytosis, where red blood cells are shaped abnormally and break down too easily, surgical removal of the spleen (called splenectomy) can be helpful. The spleen is the organ that normally filters out old or damaged red blood cells, so removing it can extend the life of the abnormal red blood cells and reduce anaemia symptoms.^[13]

Emerging Treatments Being Tested in Clinical Trials

Beyond the standard treatments that doctors use every day, researchers are actively investigating new approaches to treating various forms of anaemia through clinical trials. These studies test whether new drugs or therapies are safe and effective before they become available for general use. Clinical trials typically move through three phases: Phase I tests safety in a small group of people, Phase II examines whether the treatment actually works, and Phase III compares the new treatment directly with existing standard treatments in larger groups of patients.^[16]

One particularly promising development for patients with beta-thalassemia, an inherited form of anaemia, is a drug called luspatercept. This medication represents a new class of treatment called erythroid maturation agents. It works by targeting specific signaling pathways in the body that affect how red blood cells mature and develop. Luspatercept binds to certain proteins that are part of the transforming growth factor-beta (TGF-beta) family, which helps reduce abnormally elevated signaling that interferes with effective red blood cell production.^[16]

The approval of luspatercept was based on results from a Phase III clinical trial called BELIEVE. This study included 336 adults with beta-thalassemia who needed regular blood transfusions. Participants were randomly assigned to receive either luspatercept or a placebo (an inactive substance) by subcutaneous injection every 21 days for up to 48 weeks. The results showed that 21.4% of patients who received luspatercept achieved at least a 33% reduction in their need for blood transfusions, compared with only 4.5% of those who received the placebo. This difference was statistically significant and clinically meaningful, as reducing transfusion burden can improve quality of life and reduce complications associated with frequent transfusions.^[16]

For patients with aplastic anaemia, a rare but serious condition where the bone marrow stops making enough blood cells, clinical trials are exploring various approaches. One area of research focuses on immunosuppressive therapies that can stop the immune system from attacking the bone marrow’s stem cells. These trials test different combinations of drugs and new immunosuppressive agents to see which approaches work best at restoring bone marrow function while minimizing side effects.^[4]

Gene therapy represents one of the most innovative frontiers in anaemia treatment, particularly for inherited blood disorders like sickle cell anaemia and thalassemia. These approaches aim to correct the genetic defects that cause abnormal red blood cell production. While still largely in early-phase trials, gene therapy has shown promising results in some patients, potentially offering the possibility of a cure rather than just symptom management. However, these treatments are complex, expensive, and not yet widely available.^[16]

Researchers are also investigating new formulations of iron supplements that might be better tolerated by patients. Some clinical trials test oral iron products with different chemical forms of iron or special coatings that reduce stomach upset. Others explore new ways of delivering iron through injections that allow larger doses to be given at once, reducing the number of treatments needed.^[12]

For anaemia associated with chronic diseases like cancer or kidney disease, studies are examining whether adjusting the doses of erythropoiesis-stimulating agents or combining them with other treatments might improve outcomes. Some trials also look at whether treating the underlying disease more aggressively can help resolve the anaemia without needing separate anaemia treatments.^[16]

Clinical trials for anaemia are conducted in many countries, including the United States, various European nations, and increasingly in other regions around the world. Patient eligibility for these trials depends on many factors, including the specific type of anaemia, its severity, previous treatments tried, other medical conditions, and age. Anyone interested in participating in a clinical trial should discuss this option with their healthcare provider, who can help determine whether any ongoing trials might be appropriate and assist with enrollment if eligible.^[3]

Supporting Anaemia Treatment Through Lifestyle Changes

While medical treatments form the foundation of anaemia care, incorporating certain lifestyle habits can significantly support recovery and help manage symptoms. Getting adequate rest is particularly important because anaemia makes the body work harder to deliver oxygen to tissues. This means listening to your body and taking breaks when feeling fatigued, dizzy, or short of breath. Most adults need seven to nine hours of sleep each night, though people with anaemia may need even more during the recovery period.^[19]

Exercise can actually help with anaemia symptoms when done appropriately. Low-impact activities like walking, swimming, gentle cycling, and dancing can improve circulation and overall well-being without overtaxing the body. However, it’s crucial to stop immediately if symptoms like dizziness, chest pain, or severe shortness of breath occur during physical activity. Starting slowly and gradually increasing activity levels as symptoms improve is the safest approach.^[20]

Stress management plays an often-overlooked role in managing anaemia. Chronic stress can worsen symptoms and may even contribute to the development of anaemia in some cases. Incorporating stress-reducing practices such as meditation, yoga, deep breathing exercises, or other relaxation techniques into daily routines can support overall health and complement medical treatments.^[21]

Staying well hydrated is another simple but important measure. Water supports the circulatory system and helps red blood cells move efficiently through blood vessels to deliver oxygen throughout the body. Adequate hydration also supports kidney function and can help prevent complications like kidney stones, which is particularly relevant for people with certain types of anaemia or those taking specific medications.^[21]

For people with iron-deficiency anaemia, how food is prepared can make a difference. Cooking food in cast iron skillets has been shown to increase the iron content of meals. This traditional cooking method allows small amounts of iron from the pan to transfer into the food, providing a simple way to boost dietary iron intake without changing what you eat.^[20]

Following up regularly with healthcare providers is essential for monitoring progress and adjusting treatment as needed. Blood tests performed at intervals help track whether hemoglobin levels are improving and whether any adjustments to medications or supplements are necessary. Never stop taking prescribed medications without consulting a doctor, even if symptoms seem to improve, as anaemia often requires sustained treatment to fully resolve.^[11]
