I've been on Zoloft 50mg for about 4 months now and my anxiety is way better, but I've put on like 8-10 pounds even though I haven't really changed my diet. My doctor mentioned it could be the medication, but I'm not sure if I should switch to something else or if this levels out eventually.
weight gain on zoloft is pretty common actually. your doctor's right to mention it - happens to a lot of people because ssris like zoloft can affect appetite, metabolism, and how your body handles cravings, especially for carbs. some folks see it stabilize after a few months, others keep gaining. the thing is, it's not always just "the medication made me hungry" - sometimes it's a combo of the drug plus feeling less anxious means you're not burning stress energy the same way, or you're moving around more normally after being wound up before.
whether you should switch depends on how much this bothers you versus how well the zoloft's actually working for your anxiety. an 8-10 pound gain sucks, but if your anxiety went from terrible to manageable, losing 10 pounds is way easier than dealing with severe anxiety again. worth asking your doctor about alternatives in the same class (some people do better on different ssris) or whether adding something like a little extra movement or tweaking carbs helps offset it without nuking your mental health gains. if you're at month 4 and it's still climbing, that's worth following up on instead of just waiting.
The good news is that metabolic side effects from SSRIs often do stabilize or even reverse after 6 - 12 months as your body adjusts, so it's worth giving it more time before switching - many people see the weight plateau. What nobody mentions much: if you haven't already, track your actual calorie intake for a week or two, because SSRIs can be sneaky about increasing appetite without you realizing you're eating more, and even small daily increases add up fast.
If it's only been 4 months, you're still in the adjustment phase - a lot of people find the appetite stuff settles down around month 6 or so, so holding steady with your current dose might be worth trying before making any changes.
Most people do experience some appetite changes on SSRIs, and 8-10 pounds over 4 months lines up with what's pretty common - your body's still adjusting to how the medication affects hunger signals and metabolism. Since the earlier answers mention waiting it out (which is solid advice), one thing that actually helped someone I know was switching up their morning routine to include more movement, which seemed to reset her hunger cues rather than just fighting cravings through diet alone. If you're not already doing some kind of regular activity, that might be worth experimenting with before you consider switching meds, since you've got good anxiety relief going right now.
