Do you feel tired all the time? Do you sometimes feel like you have no energy and find it hard to breathe? These may not just be tiredness. There may also be a small problem with the red blood cells in your body. Today, we will talk about this condition called Macrocytic Anemia.
What is Macrocytic Anemia?
Simply put, Macrocytic Anemia is a blood disorder in which your bone marrow produces abnormally large red blood cells . Think of it like the little cars in our bodies that carry oxygen around. But these big red blood cells are like big but useless cars. They lack the nutrients that normal red blood cells need to function properly. This is not a serious disease, but if not treated properly, it can lead to serious health problems. Got it?
What are the main types of macrocytic anemia?
There are two main types of macrocytic anemia. These occur when your body lacks certain nutrients. Let's take a look at what they are.
1. Megaloblastic macrocytic anemia
This is the most common type. It occurs when you don't get enough vitamin B12 and/or vitamin B9 (folate). Without these nutrients, your bone marrow can't make healthy red blood cells. That means it can't make the cells that carry oxygen around your body. Think of it like a person who's working without food. The other thing is, the abnormal cells that form in this way die before the normal cells. So the number of red blood cells in the body decreases.
2. Non-megaloblastic macrocytic anemia
This type can develop if you have other health conditions that affect your body's ability to absorb nutrients. This means that even if you eat well, your body isn't getting the nutrients it needs. Some diseases can cause this.
Conditions that cause non-megaloblastic macrocytic anemia
There are several main reasons for this:
- Myelodysplastic syndrome: This is actually a group of diseases. What happens here is that something is wrong with your bone marrow and it can't make healthy blood cells. It's like a broken machine in a factory that can't make good goods.
- Alcohol use disorder: When you drink too much alcohol, your body stops absorbing vitamin B12. This is a problem for many people. Some people think that drinking a little is okay, but it is when you drink too much that problems arise.
- Hypothyroidism: This is a condition that affects the functioning of the thyroid gland. This small gland in our neck controls many of the body's functions. So, when it is underactive, anemia like this can occur.
Why does macrocytic anemia occur?
As you can see, this condition is mainly caused by a lack of vitamin B12 and/or folate (vitamin B9), which are essential for the production of healthy red blood cells, or by other medical conditions that prevent the body from absorbing these nutrients. Simply put, the "ingredients" that make red blood cells are either not enough, or the body is unable to absorb them.
How do doctors detect this?
If you have these symptoms, the first thing a doctor or nurse will do is examine you and ask you about your symptoms. They will ask you how long you've been feeling tired, what your diet is like, and whether you have any other medical conditions. They may then order blood tests, such as:
- Complete blood count (CBC): This is a basic blood test that is often done. It checks your red blood cell count, white blood cell count, and platelet count. It can also check if your red blood cells are enlarged in macrocytic anemia and what their hemoglobin level is.
- Peripheral blood smear (PBS): This is a special test. Unlike some blood tests, doctors take a sample of your blood, smear it on a glass slide, stain it, and look at it under a microscope to check for blood cells. This allows them to see the shape, size, and color of the cells. Large red blood cells (macrocytes) can be seen clearly.
- Reticulocyte count: Reticulocytes are new, immature red blood cells. They are like "baby" cells that are formed in the bone marrow and then released into the bloodstream. This test checks whether your bone marrow is producing enough healthy red blood cells. This test can give you an idea of how efficiently your bone marrow is making new cells in response to anemia.
Along with these tests, separate tests can also be done to check vitamin B12 and folate levels, if necessary.
How is this treated?
Treatment depends on the underlying cause of the condition. Doctors will try to help your bone marrow produce healthy red blood cells again.
Imagine that you are suffering from this condition because you are not eating enough, or because your diet is deficient in vitamin B12 or folate . Many vegetarians are at risk of vitamin B12 deficiency, as it is found mostly in animal products. If so, your doctor may prescribe you supplements containing this nutrient, either in the form of pills or injections. You may be asked to take these supplements until blood tests confirm that your bone marrow is making healthy red blood cells.
Sometimes, people eat well, but there is a problem that prevents the body from absorbing those nutrients . For example, this can happen due to some stomach problems. In such cases, the doctor may also prescribe supplements.
The most important thing is to treat the underlying cause.
For example, some people have medical conditions (like myelodysplastic syndrome) that prevent the body from absorbing essential nutrients. In that case, the condition needs to be treated. If you have hypothyroidism, taking medication for it can also help with your anemia.
Many people develop this macrocytic anemia because they drink too much alcohol. If so, your doctor may refer you to therapy and counseling to help you control your alcohol use. This is not easy, but it can be done with help.
Can this be prevented from happening?
Since there are many causes of macrocytic anemia, it is difficult for us to prevent some underlying medical conditions. However, if you do not have such a specific medical condition, there are several steps you can take to reduce, and possibly even prevent, this risk:
- Take care of your overall health: Symptoms of macrocytic anemia can be mild at first, but they can get worse over time. If you notice any changes in your body, such as extreme fatigue, fatigue, chest pain, or pale skin , talk to your doctor right away. Don't just assume that you've been "too busy these days."
- Eat a healthy diet: Often, the biggest risk factor for this is not getting enough vitamin B12 and/or folate. Therefore, it is very important to eat a balanced, nutritious diet.
- Foods rich in vitamin B12: meat, fish, eggs, milk and dairy products (yogurt, cheese).
- Foods rich in folate: Green vegetables, leafy greens (spinach, kale, lettuce), pulses, beans, lentils, oranges, peanuts.
Try adding these to your meals.
What happens if I have Macrocytic Anemia?
Many people recover from this macrocytic anemia after taking vitamin supplements. That means the outcome is usually good. However, the prognosis for someone with an underlying medical condition depends on the underlying medical condition and their individual situation. Your doctor will explain this to you.
How do I take care of myself?
If you have this condition, you can do these things to take care of yourself:
- Take the supplements prescribed by your doctor exactly for the duration of the treatment. This is very important. Some people stop taking their medication when they feel a little better, so don't do that.
- Develop healthy eating habits to ensure you get enough vitamin B12 and folate. You may also want to seek advice from a nutritionist.
- If you feel like your anemia symptoms are coming back (e.g., feeling tired again, feeling faint), see your doctor immediately.
- If alcohol use is a problem, get help to control it.
So, as you can see, people develop macrocytic anemia when they don't get enough nutrients that help their bodies grow healthy red blood cells. This can happen to people who follow certain diets or have certain underlying medical conditions. Remember, macrocytic anemia isn't a serious condition, but it can lead to serious medical problems if left untreated. Eating a healthy diet can help you prevent this condition. If you're concerned about this, talk to your doctor. He or she can assess your condition and recommend ways to improve your diet. If you have macrocytic anemia, your doctor will likely prescribe supplements to help replenish the nutrients that are lacking. He or she will also help you develop healthy habits.
