Physical inactivity can lead to weight gain and increase LDL cholesterol levels while decreasing HDL (high-density lipoprotein) cholesterol levels, which is beneficial for heart health.
Unhealthy Diet
Consuming foods high in saturated fats, trans fats, and cholesterol can increase LDL cholesterol levels. These include fatty meats, full-fat dairy products, fried foods, processed snacks, and baked goods.
Obesity
Being overweight or obese can lead to higher LDL cholesterol levels and lower HDL cholesterol levels.
Smoking
Smoking damages blood vessels and reduces HDL cholesterol levels, making it easier for LDL cholesterol to accumulate in the arteries.
Genetics
Family history and genetics can influence cholesterol levels. Some people inherit genes that cause them to produce too much cholesterol or to have difficulty removing LDL cholesterol from the blood.
Medical Conditions
Certain medical conditions, such as diabetes, hypothyroidism, and kidney disease, can affect cholesterol metabolism and lead to high cholesterol levels.
