What Exactly is Cholesterol? Cholesterol is a waxy, fat-like substance found in your blood. It plays an essential role in building cell membranes, synthesising hormones, and producing vitamin D (National Heart, Lung, and Blood Institute [NHLBI], 2022). However, excessive cholesterol in the bloodstream can lead to serious health problems. [IMAGE1] (British Heart Foundation, 2024) There are two primary types of cholesterol: Low-density lipoprotein (LDL): Often referred to as "bad" cholesterol, it transports cholesterol to tissues but can cause fatty deposits to build up in arteries. High-density lipoprotein (HDL): Known as "good" cholesterol, it carries excess cholesterol back to the liver for removal. Maintaining a balance between these types is vital. Elevated LDL or low HDL can increase the risk of atherosclerosis and cardiovascular diseases (Mach et al., 2019). The Cold, Hard Facts High blood cholesterol is a significant risk factor for developing heart and circulatory diseases. High LDL (“bad”) cholesterol is associated with 1 in 5 heart and circulatory disease deaths in the UK It’s estimated that close to half of adults in the UK are living with cholesterol levels above national guidelines total cholesterol (greater than 5mmol/L) Many people living with heart and circulatory diseases will have an even lower target cholesterol level At least 7-8 million adults in the UK are currently taking lipid-lowering drugs such as statins (British Heart Foundation, 2024) [IMAGE2] The Silent Symptoms: Why High Cholesterol Often Goes Unnoticed High cholesterol is often symptomless, earning its "silent" reputation. Without regular testing, many remain unaware of elevated levels until complications arise. Untreated high cholesterol can contribute to: Angina: Chest pain due to reduced blood flow to the heart. Shortness of Breath: A potential sign of cardiovascular strain. Peripheral Artery Disease (PAD): Manifested as leg pain while walking due to blocked arteries. Stroke or Heart Attack: Sudden symptoms like numbness or weakness in limbs may indicate advanced cardiovascular disease (NHLBI, 2022). Long-Term Effects of Untreated High Cholesterol The British Heart Foundation (BHF) reports that high cholesterol is a major contributor to atherosclerosis, a condition where arteries harden and narrow due to plaque buildup (BHF, 2023). This condition can lead to: Heart Disease: Elevated LDL accelerates plaque formation, increasing the risk of heart attacks (Ference et al., 2017). Stroke: Plaque fragments can obstruct brain arteries, leading to ischaemic stroke (Mach et al., 2019). Peripheral Artery Disease (PAD): Restricted blood flow to extremities may cause severe pain, tissue damage, or even amputation in advanced cases. Kidney Disease: Atherosclerosis in renal arteries impairs kidney function (Chroni et al., 2021). Take Control: The Power of Knowing Your Numbers Routine cholesterol checks are essential for proactive health management. The UK’s NHS recommends cholesterol testing every five years for adults over 40 or more frequently for those with additional risk factors like obesity, smoking, or family history of heart disease (NHS, 2023). Early detection enables timely intervention through diet, exercise, or medication such as statins.
