Sometimes a doctor may have told you to check your blood homocysteine levels. Or you may have read about it somewhere. What exactly is homocysteine ? How is it important for our bodies? Let's understand these things simply, shall we?
What is Homocysteine?
Simply put, homocysteine is an amino acid found in our blood. It's like a chemical that helps our bodies make proteins. Vitamins B12, B6, and B9 (also known as folate) are essential for our bodies to break down homocysteine and help make other important chemicals that our bodies need.
However, if this homocysteine level increases above the recommended level, it can be a bit of a problem. It can damage the inner lining of our blood vessels, that is, arteries. It's like rust eating away at the inside of a water pipe. Not only that, but blood clots can form inside the blood vessels, or the veins can become blocked. Things like this can lead to serious, life-threatening conditions like a heart attack or stroke.
Normally, the level of homocysteine in the blood of a healthy person should be between five and fifteen micromoles (5-15 mcmol/L). You can check if this is the exact amount in your body by doing a homocysteine test.
What does homocysteine do in the body?
Now look, when this homocysteine combines with the B vitamins that we talked about earlier, it turns into two other very important things. What are they?
- One is methionine . This is also a type of amino acid. Also, methionine acts as a powerful antioxidant. It helps a lot in making proteins in our body.
- The other is Cysteine . This is made from the previously mentioned Methionine. Cysteine reduces unnecessary inflammation in our body, It helps maintain good communication between cells in the immune system, and also improves the health of our liver.
So you can see, homocysteine is not just a random thing, it's what makes these important, healthy things happen. But the problem is when it gets too high.
Why do these homocysteine levels increase?
Okay, so why do homocysteine levels increase in some people for no reason? One reason for this could be a medical condition you have. But that's not all, there are several other factors that can cause homocysteine (`Hcy`) levels to increase. Let's see what they are:
- As we age: Yes, we all age. So, homocysteine levels can increase slightly with age.
- Gender: In general, men tend to have slightly higher homocysteine levels than women. In women, after menopause, that is, After menstruation stops, this level is likely to increase.
- Tobacco use: This is something that applies to many people. This is a big risk for those who smoke cigarettes or use other tobacco products. Smoking has been found to increase homocysteine levels.
These are some of the main factors that contribute to increased homocysteine levels.
What happens if homocysteine gets too high?
Imagine, what happens if your blood homocysteine level rises above 50 mcmol/L? That's when the real problem begins. This excess homocysteine (`Hcy`) starts to damage our arteries, the blood vessels that carry oxygen- rich, clean blood throughout the body.
Also, when homocysteine levels increase, it can lead to a dangerous condition called atherosclerosis . Simply put, this is when fat and cholesterol build up inside our blood vessels, clogging them up. It's like garbage getting stuck in a drain. When homocysteine levels increase, this condition of atherosclerosis can become more severe and can even occur more quickly.
So, what are the risks of this type of damage to the arteries, the development of atherosclerosis, and blood clots?
- Heart attack or heart failure.
- A stroke or paralysis-like condition.
- Atrial fibrillation is an abnormality in the heart rhythm.
Remember, a healthy person's homocysteine level is between 5 mcmol/L and 15 mcmol/L. Most of this amount is converted into other proteins. Some people may have slightly (15-30 mcmol/L) or moderately (30-100 mcmol/L) elevated levels. However, anything over 100 mcmol/L is considered severely elevated , and the potential for harm is high.
What conditions can cause increased homocysteine?
Normally, what happens in our bodies is that this homocysteine (`Hcy`) breaks down and becomes other substances, and only a very small amount remains in the blood. But there are some diseases that interfere with the process of breaking down homocysteine. That's when the homocysteine level in the blood just goes up.
If you have any of the following conditions, you are more likely to have elevated homocysteine levels:
- Chronic kidney disease : This problem can occur if the kidneys are not working properly.
- Vitamin B12, vitamin B6, or folate deficiency (meaning the body doesn't have enough of these essential vitamins).
- Dementia (this is mainly a disease of memory loss).
- Different types of heart disease.
- Homocystinuria : This is a rare, genetic condition in which the body is unable to properly utilize the amino acid methionine.
- Hypothyroidism : This means decreased function of the thyroid gland.
- Osteoporosis : This causes bones to become weak and easily broken.
- Psoriasis : This is a skin disease.
So, if you have this condition, it's very important to be aware of your homocysteine levels and talk to a doctor.
How do I know if I need to get a homocysteine test? Are there any symptoms?
So, how do we know when it's time for us to get this homocysteine test? Typically, a doctor may suggest this test if you have symptoms of vitamin B deficiency . What are the common symptoms of vitamin B deficiency? Let's take a look:
- Feeling like your head is spinning (vertigo).
- Feeling tired all the time for no reason (`Fatigue`).
- Feeling like your chest is pounding and it's hard to breathe (heart palpitations).
- Feeling weak and powerless in the muscles.
- There may be changes in skin color, possibly pallor.
- Numbness in the limbs or a feeling like ants are running around.
- Frequent occurrence of sores on the tongue or mouth.
If you have these symptoms, don't panic and think you have high homocysteine. However, the best thing to do is to see a doctor and talk about it. He or she can examine you and decide whether you really need this test or not.
How can I lower my homocysteine levels?
Okay, so let's say you've been tested and found out that your homocysteine levels are high. So what can you do to lower them? Don't worry. Your doctor will likely suggest the following:
- Taking vitamin B6 supplements .
- Taking vitamin B12 supplements .
- Taking folic acid supplements (this is the synthetic form of folate, often taken in pill form).
You can add more foods containing these vitamins to your daily diet, such as green vegetables, nuts, and dairy products. However, there is one very important thing to remember here.
Taking vitamins alone won't reduce your risk of heart disease. To really reduce your risk of heart disease, you need to do a few other important things:
- Completely abstaining from tobacco products. That means staying away from things like cigarettes and bidis.
- Reducing the amount of salt added to food.
- Be physically active for at least 150 minutes a week. That means doing exercise like walking, running, or cycling.
- Properly controlling your blood pressure.
Look, homocysteine is actually something that our bodies use and need. Normally, very little is left in the blood. So, knowing that your homocysteine level is high can be a bit scary and worrying. But, it's not something that can't be changed. Based on the results of your homocysteine test, your doctor will give you the supplements you need, namely vitamins. He or she will also advise you to make some changes in your daily habits and lifestyle to keep your heart and blood vessels healthy.
What is the most important thing we can learn from this?
Homocysteine is an important substance in our body, but if it exceeds the recommended level, it can lead to dangerous conditions such as heart disease and stroke. In particular, vitamin B deficiency, aging, gender, and smoking are the main factors that affect the increase in homocysteine levels.
If you have symptoms of a vitamin B deficiency, or if your doctor suspects this, it is wise to agree to a homocysteine test.
The most important thing is not to panic even if this level is high, but to act in an orderly manner according to medical advice. Taking vitamin supplements and adopting a healthy lifestyle can go a long way in controlling this condition. So, always take care of your health, and never forget to talk to a nearby doctor if you have any questions or doubts.
