We're all a little scared of the word "cholesterol," aren't we? We often hear that high cholesterol can lead to heart attacks and strokes. There's actually a lot of truth to this story. When cholesterol builds up in our blood vessels and starts to clog them, it's when these dangerous diseases become a problem. So today, let's talk about what these cholesterol deposits are, how they form, and how to avoid them and stay healthy.
What is cholesterol deposition and atherosclerosis?
Simply put, it's like the dirt that builds up inside our water pipes and clogs them over time. Cholesterol, fat, and other substances build up in the blood vessels, called arteries, and form "plaques." In medicine , this process is called atherosclerosis .
The main culprit for this is LDL cholesterol . As we all know, this is called "bad cholesterol" . This LDL cholesterol is what damages the walls of the arteries and begins to deposit there. The most dangerous thing is that this phenomenon develops very silently inside the body for years without any symptoms.
This condition, called atherosclerosis, is the main cause of serious conditions such as heart attacks, strokes, and peripheral arterial disease.
How do these cholesterol deposits form?
This doesn't happen overnight. This is a very complex process that takes years. Imagine that our arteries are like tubes with a very smooth, silky surface on the inside. This process happens like this.
- Step 1: Damage to the artery wall: Things like high cholesterol, smoking, high blood pressure, and diabetes can scratch, or damage, the smooth inner lining of the arteries (endothelium). It's like scratching a beautiful wall.
- Step 2: Cholesterol Ingress: From these damaged areas, the "bad" LDL cholesterol floating in the blood gradually infiltrates the artery wall. Then it begins to accumulate there.
- Step Three: Plaque Formation: Our body's white blood cells come there to "eat" this cholesterol that has entered the artery wall. But this is like a war. Over time, all these dead cells and cholesterol accumulate and form a thick mass like porridge. That's what we call cholesterol plaque.
This condition is so common that sometimes the early stages of these deposits (fatty streaks) can be seen even in the arteries of young people.
What harm can these deposits cause to our bodies?
Once formed inside the artery wall, these deposits can behave in different ways. Some of them may not grow large and remain that way. Some of them may grow larger and gradually block the blood flow. But the most dangerous thing that can happen is that this deposit suddenly bursts (ruptures) .
When that happens, our body immediately forms a blood clot to close the wound. Imagine what would happen if a blood clot suddenly formed inside an already narrowed artery and completely blocked it? That is the primary cause of a heart attack or stroke.
| Medical condition | How it happens and what it means |
|---|---|
| Coronary Artery Disease | When these deposits form in the arteries that supply blood to the heart, they can cause chest pain (angina). If the deposit ruptures and completely blocks the artery, the heart muscle dies without blood supply. We call this a heart attack . |
| Cerebrovascular Disease | If a clot in an artery that supplies blood to the brain bursts, it can damage the brain and cause a stroke . Sometimes the artery is temporarily blocked and symptoms come and go. We call this a TIA (Transient Ischemic Attack). This is a serious warning sign that a major stroke is coming. |
| Peripheral Arterial Disease (PAD) | Blockage of the arteries that supply blood to the legs. This can cause pain in the legs when walking, and slow healing of wounds. If the disease progresses, it may even require amputation of the legs. |
How do we escape this dangerous situation?
The good news is that atherosclerosis is a preventable condition. There are 9 major risk factors that cause 90% of heart attacks. Let's take a look at what they are.
| Risk factor | What we need to know |
|---|---|
| Smoking | Directly damages the arterial walls. |
| High cholesterol | Provides the raw material needed to form deposits. |
| High blood pressure | It damages the artery walls by applying pressure to them. |
| Diabetes | Increased blood sugar levels are harmful to arteries. |
| Abdominal obesity (belly fat) | A sign that increases the risk of heart disease. |
| Stress | Long-term stress is harmful to the body. |
| Eating less fruits and vegetables | The body does not receive the antioxidants it needs. |
| Excessive drinking | Affects cholesterol and blood pressure. |
| Lack of physical exercise | Reduces good cholesterol levels and increases bad cholesterol. |
As you can see, most of these risk factors are things we can control . That means we have a great chance of avoiding this dangerous disease by changing our lifestyle.
How to treat and manage?
Atherosclerosis is difficult to completely reverse. However, with the right treatment and lifestyle changes, these deposits can be stopped or slowed down . There is also evidence that some powerful treatments can shrink or even remove deposits.
Lifestyle Changes
This is the most important and first thing to do.
- Exercise: Whether you lose weight or not, daily exercise increases "good" HDL cholesterol.
- Healthy diet: Eat a diet high in fiber and low in fat. Eat more fruits, vegetables, and greens.
- Omega-3: Foods rich in omega-3, such as oily fish (salmon, mackerel, herring), can increase "good" HDL cholesterol.
- Quit smoking: Quit smoking today. It's one of the best gifts you can give your heart.
Medications
In addition to lifestyle changes, some people may be prescribed medication by their doctor.
- Statins: These are the most commonly used cholesterol-lowering drugs. They can significantly reduce "bad" LDL cholesterol. (Ex: Atorvastatin, Rosuvastatin, Simvastatin). They stabilize plaques and reduce the risk of rupture.
- Fibrates: These help reduce another type of fat called triglycerides (e.g. Gemfibrozil, Fenofibrate).
- Blood pressure medications: If you have high blood pressure, you should take the medication prescribed to control it exactly as prescribed.
- Blood thinners: Medications like aspirin and clopidogrel can reduce the risk of blood clots. However, never start taking these medications without first consulting your doctor .
Special procedures that may be performed at times
If the arteries are severely blocked and the symptoms are severe, doctors may resort to special procedures.
- Angioplasty and Stenting: In this, a very thin tube (catheter) is passed through an artery in the leg or arm to the heart, a small balloon is inflated at the blocked area, and a small mesh-like tube (stent) is then placed in the artery to prevent it from narrowing again.
- Bypass Surgery: In this, surgeons take a healthy blood vessel from another part of the body (leg or chest) and create a new route for blood to flow around the blocked area. Much like creating a bypass to bypass a roadblock.
Because these methods carry some risks, they are only recommended in extreme cases.
Take-Home Message
- Atherosclerosis is a dangerous condition that develops silently inside the body for years. Don't wait for symptoms to appear.
- Your lifestyle is your greatest weapon. Healthy eating, exercise, and quitting smoking can make a big difference.
- Always be aware of your cholesterol, blood pressure, and sugar levels. Get regular medical checkups.
- If you have any concerns or a family history of cholesterol or heart disease, be sure to talk to your doctor about it.
- Take your medication exactly as prescribed by your doctor, at the prescribed time. Avoid starting or stopping medication on your own.
