Cholesterol - Part 1
Cholesterol Unveiled
Cholesterol is ESSENTIAL in the body!
Yes, you read that right. Your body actually needs cholesterol to function properly. It's not just a terrible boogeyman gumming up your arteries. It plays a vital role in your health and having too low cholesterol is a major problem. Let's dig deeper into what cholesterol really does and why it's absolutely essential.
Cholesterol serves as a fundamental building block for hormones like estrogen and progesterone. These hormones play a crucial role in keeping you in tip-top shape.
Picture cholesterol as a waxy, fat-like substance that your liver produces and can also be found in certain foods. It's not just any ordinary substance though. Cholesterol is a vital component of cell membranes, keeping them strong and intact. It even helps in the production of bile acids, which does wonders for digesting and absorbing dietary fats. But wait, that’s not all! Cholesterol is also a key player in the synthesis of vitamin D and various hormones, including estrogen and progesterone.
This means, without enough cholesterol, your hormones can be out of balance, you won’t be able to produce or absorb vitamin D properly, and your digestion doesn’t work as well (specifically, you won’t absorb healthy fats properly). Cholesterol is a big deal in the body.
Understanding LDL and HDL Cholesterol
Now, let's shift our focus to two important players in the cholesterol game: LDL (low-density lipoprotein) and HDL (high-density lipoprotein) cholesterol. Understanding the difference between these two is absolutely crucial for maintaining a healthy heart and overall well-being.
LDL cholesterol, also known as the "bad" cholesterol, carries cholesterol from the liver to the cells throughout our body.
LDL cholesterol isn’t actually a villain, it lends a helping hand when it comes to healing damage in our arteries. It's time to see the positive side of this so-called "bad" cholesterol!
You see, when our arteries suffer from damage, whether it's due to inflammation or injury, our body kicks into action to repair them. And guess who shows up on the scene? LDL cholesterol, our hero!
Here's how it goes down: LDL cholesterol plays a crucial role in the process of repairing damaged arteries. It acts like a repair crew, transporting important substances, including cholesterol itself, to the site of injury. Think of it as the building blocks needed to rebuild and restore the health of our arteries.
LDL cholesterol also helps in the production of substances that promote healing, such as collagen. Collagen is like the glue that holds our arteries together, ensuring they stay strong and resilient.
Here's the catch: when there's too much LDL cholesterol or other factors at play, it can lead to a dangerous buildup of cholesterol in our arteries, forming what we call plaque. Over time, this plaque can clog up the arteries, restricting blood flow and putting us at risk for heart disease and stroke. I like to focus on why LDL is building plaque in your arteries and get to the core root issue instead of vilifying this healing lipoprotein.
So, let's appreciate the multifaceted nature of LDL cholesterol and give credit where credit is due. It's not always the villain it's made out to be. Our body has a way of utilizing even the so-called "bad" cholesterol for the greater good of our overall health.
Now let’s look at LDL’s friend HDL cholesterol. This is known as the "good" cholesterol and keeps things tidy and maintain the health of our precious blood vessels.
Think of HDL cholesterol as the janitor of our bloodstream. Its primary mission is to sweep through our arteries and clean up any excess cholesterol that might be hanging around. It's like a mini vacuum for your arteries.
Here's how it works: HDL cholesterol cruises around, picking up stray cholesterol particles that might have found their way into our arteries. It's like playing a game of cholesterol scavenger hunt, where HDL cholesterol goes on a mission to collect as much excess cholesterol as possible.
Once HDL cholesterol gathers up all those cholesterol bits, it doesn't just throw them back into circulation. Oh no, it's much smarter than that! HDL cholesterol actually transports those cholesterol molecules back to our liver, where they can be broken down and eliminated from our bodies.
By cleaning up the excess cholesterol, HDL cholesterol helps prevent the buildup of plaque in our arteries. It's like a diligent housekeeper making sure our blood vessels stay nice and clear, promoting healthy blood flow and reducing the risk of heart disease.
And here's an exciting bonus: HDL cholesterol doesn't just stop at cleaning duties. It also has some special powers to protect our arteries. It can reduce inflammation, which is like putting out a fire before it spreads. Plus, HDL cholesterol can even help repair minor damage in our blood vessels, keeping them in tip-top shape.
So, instead of looking at HDL and LDL cholesterol as being “good” vs. “evil”, I think it’s better to look at each of their roles and the importance of balance. If your liver is producing a lot of LDL cholesterol, it’s a sign that some repair is needed. If your HDL is high, then your body is cleaning things up. Looking at why your body is needing to produce the LDL cholesterol and understanding why there’s repair needed is a more holistic way of looking at these two types of cholesterol.
Cholesterol's Impact on Heart Health – when it’s a problem
Cholesterol's impact goes way beyond just our hearts. When our LDL cholesterol levels skyrocket and our HDL cholesterol levels plummet, our risk of heart disease goes through the roof. The buildup of plaque in our arteries can lead to a condition called atherosclerosis, which means our arteries narrow and harden, making it harder for blood to flow to our vital organs.
Remember though – high LDL is there to FIX a problem, so we need to look at the source of inflammation.
High levels of LDL cholesterol can also contribute to blood clot formation, putting us at an increased risk of heart attacks and strokes. On the other hand, having enough HDL cholesterol in our system helps remove excess cholesterol from our arteries, acting as a shield against these problems.
Cholesterol and brain function
This is important - Cholesterol isn't just about our hearts. Research suggests that it plays a role in your brain function. Adequate levels of cholesterol are essential for keeping our brains sharp, as it's involved in forming and maintaining connections between brain cells.
Low levels of cholesterol have been associated with an increased risk of dementia and Alzheimer’s Disease. Cholesterol is a key ingredient in the myelin sheath that protects nerve fibers and plays a key role in how neurons communicate with each other.
There are also some early indications that long-term use of statin drugs (used to lower cholesterol) may increase one’s risk of dementia. More research is needed, but it’s concerning.
Cholesterol - Hormones & Mood
Cholesterol is integral to hormone production, it makes sure everything runs smoothly. Our body uses cholesterol as a building block to create hormones like estrogen, progesterone, and testosterone.
But what's the connection between cholesterol and mood? Well, hormones have a significant influence on how we feel and behave, and cholesterol helps keep their levels in check. When our cholesterol levels are well-balanced, our hormone production is, too, which can contribute to stable moods and overall emotional well-being.
Think of it this way: Cholesterol acts as the conductor of a hormone symphony, ensuring that each hormone is playing its part in harmony. When cholesterol levels are too low, it can throw off the delicate balance, potentially leading to mood swings, irritability, or even feelings of sadness.
But, I’m not saying that we need high cholesterol either! It's all about finding that sweet spot where cholesterol levels are balanced for optimal health. Too much cholesterol can still have negative effects on heart health and overall well-being, so it's important to maintain a healthy lifestyle and keep cholesterol levels in check.
This is why I believe we need to take a more holistic view of cholesterol. By understanding what cholesterol is, differentiating between LDL and HDL cholesterol, and recognizing its role in heart health, we can make informed decisions about our lifestyle, diet, and self-care practices.
Stress and its Impact on Cholesterol Levels
Cholesterol plays a surprising role in one of our most primal instincts—the stress response.
Anytime you find yourself in a nerve-wracking situation, heart racing, palms sweating—the fight-or-flight response in full swing. But what does cholesterol have to do with this survival response?
When stress strikes, our bodies release a cascade of hormones, including adrenaline and cortisol, to prepare us for action. These hormones signal the liver to produce more glucose, providing an instant energy boost to fuel our fight or flight. But here's where cholesterol steps onto the stage: it serves as a precursor for the production of these stress hormones.
You see, cholesterol acts as a raw material, a building block, for the synthesis of cortisol and other stress-related hormones. Our adrenal glands, those steadfast guardians of stress regulation, rely on cholesterol to create these vital messengers. Without adequate cholesterol levels, the stress response may not work properly, leaving us ill-prepared to face life's challenges head-on.
However, it's crucial to maintain a delicate balance. While cholesterol is essential for the stress response, excessive levels can tip the scales toward chronic stress, which can have detrimental effects on our health. Prolonged stress can ask the body to produce excess cholesterol AND inflammation.
This is particularly important because I feel it’s not often talked about. Stress, and stress alone, can be the culprit behind high cholesterol (and high blood pressure and blood sugar). Therefore, stress management becomes your best tool at keeping all of these levels in check.
Menopause and Cholesterol
The connection between menopause and cholesterol is intricate and important to understand. Many women will receive a diagnosis of high cholesterol during these years and understanding why can help you find balance :).
Menopause and its Impact on Cholesterol Levels:
During this phase, our hormones undergo a significant shift as the ovaries gracefully retire. Estrogen and progesterone begin to decrease in production, and this hormonal dance can have a profound impact on our cholesterol levels.
Estrogen and progesterone play numerous roles in our body, they’re more than just our fertility hormones. Brain health, bone strength, connective tissue repair are just a few other body systems that are impacted when your estrogen levels drop.
Estrogen has a remarkable role in maintaining a healthy cholesterol balance. It's like a guardian angel, boosting our levels of high-density lipoprotein (HDL) cholesterol, the "good" cholesterol that helps sweep away excess cholesterol from our bloodstream. On top of that, estrogen has the power to lower levels of low-density lipoprotein (LDL) cholesterol, the "bad" cholesterol that can clog our arteries like a stubborn traffic jam.
But as menopause knocks on our door, estrogen bids us farewell, and this delicate cholesterol-balancing act becomes disrupted. The decline in estrogen throws our cholesterol profile off balance, with LDL cholesterol creeping up and HDL cholesterol taking a nosedive. It's like a roller coaster ride we didn't sign up for!
How Menopause Can Influence Your LDL & HDL levels:
When estrogen takes its leave, it leaves behind a void that impacts our cholesterol levels. Estrogen is like a cheerleader for our liver, encouraging it to escort LDL cholesterol out of the bloodstream. But as estrogen dwindles, this protective effect diminishes, allowing LDL cholesterol to hang around longer than it should.
Here's the cold, hard truth—menopause puts us at a higher risk of heart disease. The changes in cholesterol levels during this phase play a significant role in this increased risk. As LDL cholesterol levels rise and HDL cholesterol levels dip, your body’s handy clean up process is less effective and your arteries become susceptible to plaque buildup, leading to a condition known as atherosclerosis.
Your once-clear arteries gradually narrow and constrict, obstructing the flow of blood to our precious heart. This means an increased likelihood of heart attacks, strokes, and other cardiovascular woes. It's like navigating a treacherous road full of potholes and detours.
I see Perimenopause and Menopause as a time to really take charge of our health…and, the body kinda insists on it. By embracing a holistic approach to wellness, encompassing lifestyle adjustments, heart-healthy eating, stress management, and joyful movement, we can steer clear of these heart health pitfalls.
Understanding the intricate dance between hormones and cholesterol empowers us to make choices that support our heart health during menopause.
