Cholesterol is a fat-like substance that moves through your blood. Your body actually needs some cholesterol because it helps build cells and make hormones.
But if there’s too much cholesterol in your blood, it can cause trouble.
You can imagine your blood vessels like water pipes. When there’s too much cholesterol, it can build up on the inside walls, like grease in a drain. Over time, this buildup makes it harder for blood to flow smoothly. That can lead to heart attacks or strokes. To help with this, many people take medicine to lower their cholesterol.
A group of scientists at the University of South Australia recently looked closely at how these cholesterol-lowering medicines work. They also explored how these drugs might affect other parts of the body, like the brain, lungs, and hormones.
The most common type of cholesterol medicine is called statins. They are used to lower bad cholesterol and reduce the risk of heart disease. Most people tolerate statins well, but some may experience stomach upset. In this new study, researchers found something unexpected.
They discovered that people taking statins had a slightly larger hippocampus. The hippocampus is a part of the brain that helps with memory. This suggests that statins might help protect memory as people get older, though more research is needed to be sure.
The researchers also looked at another type of drug called PCSK9 inhibitors. These are newer cholesterol medicines that work differently than statins. Instead of slowing down cholesterol production, they help the body remove more cholesterol from the blood.
These drugs can be helpful for people who can’t take statins or need extra help lowering cholesterol. However, the study found that these drugs might have an effect on the lungs. It’s not clear yet how serious this is, so scientists say it’s important to keep studying these drugs carefully.
There was another surprising finding. Some people who took statins gained weight and had more body fat. In men, statins were also linked to lower testosterone levels, which can lead to lower energy or changes in mood. This shows that while cholesterol drugs can be very helpful, they may also come with side effects.
This kind of research helps doctors and patients make better choices. For example, if someone already has lung problems, their doctor may want to be cautious with PCSK9 inhibitors. Or, if a man taking statins notices changes in his energy or mood, it might be related to the medicine.
In the end, cholesterol drugs like statins and PCSK9 inhibitors are powerful tools for protecting heart health. But they affect different people in different ways. That’s why it’s important to work closely with your doctor, ask questions, and stay informed.
The study from the University of South Australia was published in the British Journal of Clinical Pharmacology. If you care about your heart and brain health, it’s a good idea to keep up with new research. The more you know, the better choices you can make for your health.
