Low-density lipoprotein, or LDL, can be understood as the bad Cholesterol, which sticks at to the walls of the blood vessels and obstructs the blood flow. This causes numerous health issues apart from heart attacks. LDL looks like a small blob whose center is made of Cholesterol and is surfaced by a rim of lipoprotein. The only way to check the LDL level is by a blood test. The considered healthy level of LDL in an Adult is less than 130 mg/dL. Its higher levels are dangerous for one's well-being as it causes certain heart-related problems due to the deposition on arteries' walls, including chest pain; it also increases the chances of heart attack and stroke. High LDL is caused by daily bad habits, including poor diet, obesity, lack of exercise, smoking, diabetes, and aging.
