can lexapro cause weight loss
Lexapro and Weight. Lexapro can cause changes in weight. There are some reports that people begin to lose weight when first taking Lexapro, but this is not well supported by research studies.The Mayo Clinic does list Lexapro, however, as an antidepressant that is less likely to contribute to weight gain.eople who have depression and anxiety also tend to have low levels of serotonin. Itâs still unknown if depression causes low levels of serotonin, or if low levels of serotonin cause depression. Whatever the answer to this chicken and egg question, Lexapro clearly increases serotonin levels in your brain.
