Depression is associated with weight gain, but the medicine you take to fight depression might make you gain weight as well.

Researchers were interested in looking at the long term risk for weight gain and obesity with continued use of antidepressants, given that older studies only looked at short term weight gain.

The scientists followed over 300,000 people, of varying weights, selected from a primary care record database in the U.K. from 2004 to 2014.

They looked for associations between body weight and specific antidepressants.

They found that those on antidepressants were 1.2 times more likely to gain weight over those 10 years than those not on antidepressants.
