Cataract Risk & Body Mass Index (BMI)

A high Body Mass Index (BMI) may increase your risk of cataracts according to some recent research. Body Mass Index (BMI) is recognized as a well known risk factor for some common diseases, such as diabetes mellitus and cardiovascular diseases but the relationship between BMI and risk of cataract is controversial and not completely obvious. The World Health Organization (WHO) defines a normal weight with a Body Mass Index (BMI) of18.5-25 kg/m2, excess body weight and being overweight as BMI of 25-30 kg/m2, and obesity as BMI of ≥31 kg/m2.


Researchers conducted an extensive Meta analysis and statistical review of BMI and cataracts and found that being overweight or obese were significantly associated with an increased risk of cataracts, especially those called “posterior subcapsular cataracts” which typically cause the greatest vision decline. This relationship was independent of sex, alcohol intake, diabetes and hypertension. A number of other studies have already identified several factors associated with an increased risk of age related cataracts including age, smoking, alcohol consumption and ultraviolet radiation. Now we have to consider BMI as a possible factor that increases the risk of cataracts.
