DEAR DOCTOR K: My doctor thinks I could benefit from an antidepressant. But I've heard that antidepressants cause weight gain and I'm already overweight. Do any antidepressants cause less weight gain than others?
DEAR READER: Many of my patients have asked me that question. Like you, they were hesitating to take antidepressants because of the possibility they would gain weight. And they're right: Many antidepressants do cause weight gain in some people. The question has been how much weight gain they cause.
