Cholesterol News and Research RSS Feed - Cholesterol News and Research

Cholesterol is a waxy, fat-like substance made in the liver, and found in the blood and in all cells of the body. Cholesterol is important for good health and is needed for making cell walls, tissues, hormones, vitamin D, and bile acid. Cholesterol also comes from eating foods taken from animals such as egg yolks, meat, and whole-milk dairy products. Too much cholesterol in the blood may build up in blood vessel walls, block blood flow to tissues and organs, and increase the risk of developing heart disease and stroke.

Morbidly obese individuals more likely to experience heart failure, say researchers

A study by Johns Hopkins researchers of more than 13,000 people has found that even after accounting for such risk factors as high blood pressure, high cholesterol and diabetes, so-called morbid obesity appears to stand alone as a standout risk for heart failure, but not for other major types of heart disease.
