How high bad cholesterol contributes to aging proccess
research in progress
It is important to note that our bodies need cholesterol to function – only healthy levels. Cholesterol is a fatty substance that is manufactured by the liver and distributed in the body. It enables our bodies to make vitamin D hormones and also makes up bile acids. High cholesterol levels mean that you have more cholesterol in your blood than your body needs to function. Having high cholesterol does not necessarily mean that you have to be overweight or obese. Cholesterol level is simply determined using a blood test.
There are two types of cholesterol. High-density lipoprotein (HDL) cholesterol picks up extra cholesterol in your blood stream and redirects it to your liver for repurposing or ejection from the body. Bad cholesterol, low-density lipoprotein cholesterol transport cholesterol to where it may be needed.
Arteries move blood from your heart to the rest of your body. Very high levels of LDL and low levels of HDL can cause your arteries to develop plaque, which is a hardened mixture of fat, cholesterol and other compounds. As the arteries narrow, not enough blood flows to your heart and this may cause a heart attack. Also, reduced blood supply can cause chest discomfort, pain in your joints and back and pressure.
How does this contribute to premature ageing? If you do not have enough energy to move about and you experience pain when you do, chances are that you will not participate in physical activity. There is a direct correlation between exercise and youthfulness. Plaque builds up also interferes with blood flow to your arms and legs making you feel pain or numbness. There is a heightened risk of infection and lack of blood to the tissues may cause tissue death (gangrene)
Your skin is very delicate. It has a dense network of tiny veins and arteries under it that supply it with blood and help with the cooling action of the skin. When blood supply s compromised, toxins are not effectively removed from your body and heat cannot be regulated well. Proteins that are required for skin elasticity and tautness are transferred by the blood. If the supply of these proteins is insufficient, the skin looks dull, gets wrinkles and looks darker.
Ageing is not only manifested on your skin. It also takes a toll on your brain. Too much bad cholesterol blocks arteries meaning that there is not enough oxygen being supplied to the brain. Brain cells rapidly get damaged and start to die. This can lead to various neurodegenerative conditions that are normally linked to old age.
High cholesterol levels can be accompanied by problems of obesity. It is a known fact that when you are overweight, you tend to look older than you really are. The skin is stretched too much and may become flaky and sag.
High cholesterol levels in the body can be decreased by leading a healthy lifestyle. Incorporating regular exercise and eating foods that lower cholesterol levels.
