We all want to be healthy, right? So it's important to be a little more aware of what's going on inside our bodies. Today we're going to talk about something you may not have heard of, but that has a huge impact on our health. That's a chemical called Homocysteine (Hcy). Don't worry, we'll simply talk about what it is, why it's important, what happens if it increases, and what to do if it does.
What is Homocysteine (Hcy)?
Simply put, Homocysteine (Hcy) is an amino acid . In other words, it's a chemical found in our blood. It helps build proteins in our bodies. Just like building a house requires bricks, our bodies need these chemicals to build different things.
Now, this Homocysteine (Hcy) is not just there in our bodies. Vitamin B12, vitamin B6, and vitamin B9 (also known as folate) work together to break down this Homocysteine (Hcy) and make other important chemicals that our bodies need. In other words, these three vitamins are like workers, using the raw material Homocysteine (Hcy) to make new things.
However, if the level of Homocysteine (Hcy) in the blood increases above normal levels, it is a bit dangerous . Because it can damage the walls of our arteries (the vessels that carry oxygenated blood from the heart to the rest of the body). Not only that, it can also cause blood clots to form inside the blood vessels or block the vessels. If that happens, the chances of developing serious diseases like heart attack and stroke are also high.
So, we can do a Homocysteine test to find out how much Homocysteine (Hcy) is in our blood. Normally, the amount of this in the blood of a healthy person is between 5 and 15 micromoles (5-15 mcmol/L) .
What does homocysteine (Hcy) do to our body?
We've already mentioned that when combined with vitamin B, Homocysteine (Hcy) is converted into other things. Now let's see, there are two main things that are formed when this is converted:
- Methionine: This is also an amino acid. It is also a powerful antioxidant. Simply put, it is like a protector that prevents damage to our cells. Methionine is also essential for making proteins in our body.
- Cysteine: This amino acid is derived from the same amino acid as methionine. Cysteine helps reduce inflammation in our bodies, helps maintain proper communication between cells in the immune system, and promotes liver health.
Just think, what an important job this homocysteine (Hcy) does in our bodies, combined with vitamins! That's why it's important to keep its levels in check.
What are the causes of increased homocysteine (Hcy) levels?
Homocysteine (Hcy) levels in the blood don't just increase. There are many reasons for this. Sometimes it can be due to a medical condition. Apart from that, there are several other factors:
- As we age: As we age, homocysteine (Hcy) levels may increase because some of the body's functions slow down.
- Men and postmenopausal women: Homocysteine (Hcy) levels are generally slightly higher in men than in women. In addition, levels may also increase in women during menopause.
- Tobacco use: People who smoke cigarettes and bidis are more likely to have elevated homocysteine (Hcy) levels. Tobacco is always harmful to the body.
These are the main contributing factors. In addition, other medical conditions can also cause elevated Homocysteine (Hcy) levels. Let's talk about that too.
What happens if homocysteine (Hcy) increases?
Imagine, if the amount of Homocysteine (Hcy) in our blood increases above 50 mcmol/L , it starts to damage the inner lining of our arteries. Arteries are the tubes that carry clean blood from the heart to the entire body. They are like water pipes. Just as rust builds up inside a water pipe, it becomes difficult for water to flow, when arteries are damaged, blood flow is impeded.
When homocysteine (Hcy) levels are high, the risk of developing atherosclerosis (a condition in which fat and cholesterol build up in the walls of arteries, causing them to narrow) increases. It can also make the condition worse in people who already have it.
"High homocysteine (Hcy) levels increase the risk of blood clots or blood vessel blockages."
This damage to the arteries, atherosclerosis, and blood clots increase the risk of developing the following serious conditions:
- Heart attack
- Stroke
- Atrial fibrillation (this is an abnormal heartbeat)
Normal levels and risk levels
We mentioned earlier that a healthy person's Homocysteine (Hcy) level is between 5 and 15 mcmol/L . At this level, most of the Homocysteine (Hcy) is converted into other proteins. However, in some people, this level may be slightly higher.
- Mild: Between 15 and 30 mcmol/L.
- Moderately high level: Between 30 and 100 mcmol/L.
- Severe: Above 100 mcmol/L.
Doctors decide on treatment based on these levels.
Diseases that affect homocysteine (Hcy) levels
Normally, Homocysteine (Hcy) is broken down into other substances, so only a small amount remains in the blood. However, some medical conditions can interfere with this breakdown process, causing elevated levels of Homocysteine (Hcy) in the blood. If you have the following medical conditions, your Homocysteine (Hcy) levels may be elevated:
- Chronic kidney disease: When the kidneys do not work properly, waste products are not filtered properly.
- Vitamin B12, B6, or folate (B9) deficiency: These vitamins help break down homocysteine (Hcy). So if you don't get enough of them, homocysteine (Hcy) builds up.
- Dementia: A condition of memory loss.
- Heart disease: This can also affect people who already have heart disease.
- Homocystinuria: This is a genetic disease in which the body is unable to properly utilize the amino acid methionine.
- Hypothyroidism: Decreased thyroid hormone levels also affect.
- Osteoporosis: A disease of bone thinning.
- Psoriasis: A skin disease.
If you have any of these conditions, your doctor may want to check your homocysteine (Hcy) levels.
What symptoms should prompt a Homocysteine (Hcy) test?
If you are experiencing symptoms of a vitamin B deficiency, your doctor may recommend a homocysteine (Hcy) blood test. We now know that homocysteine (Hcy) increases when vitamin B is deficient. The most common symptoms of vitamin B deficiency are:
- Dizziness
- Fatigue
- Heart palpitations
- Muscle weakness
- Skin color changes
- Tingling in your feet, arms or hands
- Tongue or mouth sores
If you continue to experience one or more of these symptoms, it's best to seek medical advice. Don't just think about taking vitamin pills.
How to reduce homocysteine (Hcy) levels?
Imagine, you had a Homocysteine (Hcy) test, and the results showed that your Homocysteine (Hcy) level is high. What should you do then? There is nothing to worry about. Your doctor will give you appropriate advice. The following are generally recommended to lower your Homocysteine (Hcy) level:
- Vitamin B6 Supplements
- Vitamin B12 Supplements
- Folic acid (synthetic form of folate) supplements
You can also get these nutrients by eating more foods that contain these vitamins. However, it is important to remember that taking vitamins alone will not reduce your risk of heart disease . To reduce your risk of heart disease, you should also do the following:
- Avoid tobacco products completely.
- Eat a low-salt diet.
- Be physically active (such as walking, running, cycling) for at least 150 minutes a week .
- Control your blood pressure.
Homocysteine (Hcy) is an amino acid that our bodies use. It is normally present in very small amounts in the blood. You may be concerned when you find out that your Homocysteine (Hcy) level is high. But it is something that can be changed. Depending on the results of your Homocysteine (Hcy) test, your doctor may recommend vitamin supplements. They may also advise you to make some changes to your daily habits to keep your heart and blood vessels healthy.
The most important things for you to remember
So, we've talked a lot about Homocysteine (Hcy) today. In summary:
- Homocysteine (Hcy) is an amino acid found in our blood that helps make proteins.
- Vitamins B6, B12, and folate (B9) break it down and make other things the body needs.
- If homocysteine (Hcy) levels increase, the risk of developing diseases such as artery damage, blood clots, heart attack, and stroke increases.
- Homocysteine (Hcy) levels can increase due to things like vitamin B deficiency, kidney disease, and smoking.
- Homocysteine (Hcy) levels can be controlled by taking vitamin B supplements and leading a healthy lifestyle.
- If you have symptoms of vitamin B deficiency or risk factors, it is wise to have a Homocysteine (Hcy) test done on medical advice.
The most important thing is to talk to a doctor about any symptoms you have and get proper advice. Don't go for treatment based on guesswork.
It's important to take care of your health. I hope this information is helpful to you!
