Millions of people around the world take cholesterol-lowering medicines every day to protect their hearts and stay healthy as they age.
Doctors often prescribe these drugs to lower the risk of heart disease, strokes, diabetes, and other serious health problems linked to high cholesterol. For many people, these medicines are life-saving treatments that help them live longer and healthier lives.
Cholesterol is a fatty substance found in the blood. The body needs some cholesterol to build healthy cells, but too much of it can be dangerous. High cholesterol can cause fatty deposits to build up inside blood vessels.
Over time, these deposits can block blood flow and increase the risk of heart attacks and strokes. Because of this, doctors have spent decades looking for effective ways to reduce cholesterol levels safely.
One of the most common types of cholesterol medicine is called statins. Well-known drugs such as Lipitor and Crestor belong to this group. Statins work by slowing down the body’s production of cholesterol in the liver. They have become one of the most widely used medicines in the world because they are effective and affordable for many patients.
In recent years, scientists have also developed a newer type of cholesterol-lowering medicine known as PCSK9 inhibitors. These drugs work differently from statins.
Instead of reducing cholesterol production, they help the body remove more cholesterol from the blood. Doctors often prescribe PCSK9 inhibitors to people who have very high cholesterol levels or who cannot tolerate statins.
Although both types of medicine can greatly lower cholesterol, researchers are now learning that these drugs may affect the body in unexpected ways beyond the heart and blood vessels. Some of these effects could be helpful, while others may cause concern.
A new study led by Kitty Pham, a Ph.D. student at the University of South Australia, explored how cholesterol-lowering medicines may influence other parts of the body. The research was published in the British Journal of Clinical Pharmacology.
Instead of running a long human trial, the research team used genetic information to study how the drugs might affect people over time. Genetics can act like a blueprint for the human body. By studying genetic patterns, scientists can predict how certain medicines may influence health in different individuals.
This method allows researchers to gather important clues much faster than traditional long-term studies, which can take many years and cost huge amounts of money.
The researchers discovered that people with certain genetic traits linked to statin use were more likely to gain weight or develop extra body fat. This finding may help explain why some people notice changes in their body shape after taking statins for a long time.
Scientists believe the drugs may affect how the body stores fat or uses energy, although more research is still needed to fully understand the process.
The study also found that statins may reduce levels of testosterone. Testosterone is an important hormone in both men and women. It helps support muscle strength, energy levels, mood, and many other functions in the body. Lower testosterone levels could potentially affect overall wellbeing in some people.
At the same time, the study also revealed something that may be positive. Researchers found signs that statins could increase the size of the hippocampus, an important part of the brain involved in memory and emotions.
Scientists are interested in this finding because changes in the hippocampus have been linked to conditions such as depression and dementia. A larger hippocampus could possibly help protect brain health, although researchers say much more evidence is needed before drawing firm conclusions.
The newer PCSK9 inhibitors also showed possible unexpected effects. According to the researchers, these drugs may influence lung function.
Scientists are still trying to understand exactly how this happens and whether it could cause long-term breathing problems for some people. Since PCSK9 inhibitors are newer medicines, researchers still have many questions about their long-term safety.
The findings highlight how medicines can have effects throughout the body, not just on the condition they are designed to treat. Modern drugs are often very powerful, and while they can bring major health benefits, they may also influence organs, hormones, or body systems in ways that are not immediately obvious.
Doctors stress that people should not stop taking their cholesterol medicine because of these findings. High cholesterol remains a major cause of heart disease worldwide, and cholesterol-lowering drugs continue to save many lives every year. For most patients, the benefits of treatment are still likely to be much greater than the risks.
However, the study does suggest that patients should pay attention to changes in their health while taking these medicines.
If someone notices weight gain, unusual tiredness, changes in mood, or breathing problems, it may be worth discussing with a doctor. Medical professionals can help decide whether the symptoms could be related to medication or caused by something else.
Research like this is important because it helps scientists better understand how medicines affect the human body over time. It may also help doctors develop more personalized treatments in the future, where medicines can be matched more carefully to a person’s genetic makeup and health needs.
As scientists continue studying cholesterol drugs, patients and doctors will gain a clearer picture of both the benefits and possible side effects of these widely used treatments. The goal is not only to lower cholesterol safely, but also to improve overall health and quality of life for millions of people around the world.
