Every year, cardiovascular illnesses cause 18.6 million fatalities, and they account for 75% of mortality in low- and middle-income nations, including India. High cholesterol is one of many risk factors, but it is a significant one. Learn more about cholesterol, how it affects heart health, and what actions need to be taken to maintain healthy cholesterol levels. Cholesterol, a waxy, fat-like substance produced by your body (liver) and partially absorbed from meals, is necessary for the formation of cell membranes, neuron insulation, hormone production, and vitamin synthesis. Bad cholesterol, or LDL (low-density lipoprotein), can accumulate in your arteries and cause heart attacks and strokes if it is present in excess. LDL (low-density lipoprotein), which is seen as bad cholesterol, and HDL (high-density lipoprotein), which is regarded as good cholesterol, make up the majority of cholesterol. The cholesterol building process known as atherosclerosis can be prevented by HDL, which protects your arteries from it. While this is happening, LDL, or bad cholesterol, builds up in the artery walls, hardening and constricting them. Heart attacks and strokes may happen from a blockage in these arteries, which are connected to your heart and brain. Blood testing are essential for the early detection because the accumulation happens gradually over time. Cholesterol is determined with the Lipid Profile test. Processed carbs, non-vegetarian meals, and deep-frying all have a tendency to raise LDL and triglyceride levels. While a diet high in fruit and vegetables, whole grains, and green leafy vegetables reduces LDL. A minimum of five days per week of exercise helps to boost HDL and lower LDL, lowering your risk of heart disease. Some drugs, including as long-term steroids and hormones, may raise LDL and lower HDL. Get your heart health tested if you are 40 years of age or younger and have risk factors include being overweight, having a family history of heart disease, living a stressful and sedentary lifestyle, or smoking.
