Does Anxiety Medication Make You Gain Weight?
When starting a medication protocol, many people wonder, “Does anxiety medication make you gain weight?” If you’re wondering this, you’ve probably heard about the impact these medications can have on your weight from a friend or colleague. But the answer isn’t a straight yes or no; it depends on numerous factors.
Some research estimates that about 25% of people who use antidepressants notice weight gain.2 A study from 2019 found that people who begin treatment with antidepressants experience a 5% increase in weight.3 However, despite these findings, weight gain isn’t necessarily directly related to the medication itself.
Numerous factors can lead to weight gain when taking anxiety medication. For example:
Some anxiety medications cause increased appetite, which may lead people to consume more calories than their body can use
Some people with anxiety or depression have a hard time staying active which could keep them from burning more calories than they consume
Some people turn to food for comfort when experiencing difficult emotions, and anxiety medications may make them more susceptible to weight gain
Anxiety medications can affect a person’s metabolism and cause them to burn calories slower than they would normally.
