As can only be expected, the list of health issues that can be attributed to obesity just keeps on growing. A Swedish study of about 37000 women and 43000 men who were tracked for 6 years, found that increase in BMI led to an increased incidence of heart failure (although for women the incidence was higher among those with greater waist circumference, whereas for men this made no difference).
Obesity is already known to increase the risk of heart disease, stroke and diabetes. But as it turns out "heart failure" is a different condition altogether:
Coronary disease is blockage of heart arteries that can eventually cause a heart attack. Heart failure is the progressive loss of the heart’s ability to pump blood.
While many patients who have heart failure also have coronary disease, this is not always so […] [Yahoo News]
Particularly troubling is the fact mentioned later in the news item, that although we have been able to stem the incidence of heart disease using newer medical techniques, heart failure is continuing to increase.
Just another reason to watch what we eat and keep active.
