Why cholesterol is necessary in body? - #12429
I am really confused about cholesterol lately. Been reading articles and listening to friends talk about it but no one seems to agree on why cholesterol is necessary in body. A few weeks ago, I went for my routine check-up and I was told my cholesterol levels are higher than they should be, which scared me a bit. They started mentioning things like “bad” and “good” cholesterol, but honestly, I don’t get it. During the visit, the doctor said something about how cholesterol is essential for various body functions, which made me think — wait, you mean it’s not all bad? When I tried to understand why cholesterol is necessary in body, the more I read, the more confused I got. Like, how can something that’s supposedly bad also be necessary? I also tried to ask my family about it, and they seemed just as lost. Can someone explain why cholesterol is necessary in body and how bad cholesterol can still be needed? I guess I’m just worried because I want to be healthy but I don’t want to be misinformed either, y’know? Any insights that can clarify why cholesterol is necessary in body would be super appreciated!

Doctors’ responses
Cholesterol can indeed be a confusing topic, especially with all the mixed messages out there. Despite its reputation, cholesterol is actually essential for several vital functions in the body. It’s a type of fat, or lipid, that plays a crucial role. For starters, cholesterol is a fundamental component of cell membranes, helping them maintain their integrity and fluidity. Without cholesterol, cells couldn’t function properly. It also serves as a precursor in the synthesis of important substances like steroid hormones, which include sex hormones like estrogen and testosterone, as well as cortisol, a hormone involved in stress response. Furthermore, cholesterol is necessary for the production of bile acids, which help us digest fats in the diet, and vitamin D, which is crucial for bone health and immune function.
Now, when it comes to the “good” and “bad” cholesterol, it’s really about how cholesterol gets transported in the blood. Low-density lipoprotein (LDL) is often labeled as “bad” cholesterol because high levels can lead to the buildup of fatty deposits in arteries, increasing the risk of cardiovascular disease. On the other hand, high-density lipoprotein (HDL) is considered “good” because it helps remove cholesterol from the arteries, carrying it back to the liver where it can be processed and eliminated. So, while you do need cholesterol, maintaining a balance between HDL and LDL is key.
If your cholesterol levels are higher than recommended, it’s a nudge towards reevaluating lifestyle factors like diet, exercise, and maybe even your stress levels. Try incorporating more fruits, veggies, whole grains, and good fats (like those from fish and nuts) as they can help improve cholesterol levels. Regular physical activity can also boost HDL levels, while avoiding smoking and limiting alcohol can keep things in check. While it’s important to be informed and concerned about maintaining healthy cholesterol levels, the goal is to manage them effectively without undue stress. Meeting with a healthcare professional who can personalize advice based on your complete health picture can also be incredibly helpful.
