The skin disorder rosacea should be added to the list of chronic diseases linked to obesity, researchers report.

Their large new study found that the risk for rosacea increases among women as weight rises.

The researchers reviewed the records of nearly 90,000 U.S. women, tracked over 14 years. They found a 48 percent higher likelihood of rosacea among those with a body mass index (BMI) greater than 35 than among women of normal weight.
