Serotonin plays a key role in regulating your moods, including feelings of happiness and anxiety. Research suggests that low levels of serotonin are associated with depression.Like other antidepressants, the effects of Lexapro aren’t immediate. It can take several weeks to begin working, and it may take one month or longer for the full mental health benefits of Lexapro medication to become apparent.Does Lexapro Cause Weight Loss?SSRIs such as Lexapro belong to a modern class of antidepressants, most of which came onto the market in the late 1980s to the 1990s, respectively. These replaced older medications for depression, many of which were well known for causing significant side effects.Although Lexapro and other SSRIs are usually less likely to cause side effects than monoamine oxidase inhibitors, tricyclic antidepressants and other older drugs, they can still potentially cause issues, one of which may be a change in your appetite and weight.In general, antidepressants are more commonly associated with an elevated risk of weight gain than undesired weight loss. For example, a large-scale cohort study from the UK found that the risk of weight gain was slightly higher in people who used antidepressants than their peers.However, not all antidepressants are equally likely to cause weight gain, and some are linked to weight loss in certain groups of people.For example, another study published in the International Journal of Neuropsychopharmacology in 2011 compared the effects of escitalopram and nortriptyline, a tricyclic antidepressant, on the body weight of people undergoing treatment for moderate-to-severe major depression.The researchers found that while nortriptyline was associated with moderate weight gain over a period of six months, the people who were treated with escitalopram only gained 0.14kg (under a third of a pound) over
