Here’s something that shouldn’t be uncomfortable to say but often is: you are allowed to bring up the weight gain with your prescriber. Not to ask to stop the medication. Not to suggest the medication isn’t working. But to say, as plainly as it needs to be said: this is affecting my quality of life, and I’d like to understand my options.
Many people don’t have this conversation. They feel like bringing up weight gain will make them sound shallow, or ungrateful, or like they’re prioritizing appearance over their mental health. They assume nothing can be done, or they don’t want to rock a treatment plan that’s keeping them stable. Or they’ve raised it before and felt dismissed, and they don’t have the energy to raise it again.
All of those are real. And none of them means the conversation isn’t worth having — because the weight and metabolic changes that accompany certain medications have clinical consequences beyond aesthetics. Insulin resistance, elevated triglycerides, increased cardiovascular risk, elevated blood pressure, and disrupted glucose regulation are outcomes that exist on a spectrum with serious long-term health consequences. They are medically relevant. And they deserve medical attention.
What the Conversation Is — and Isn’t
Before going into the specifics, it helps to be clear about what you’re asking for.
You are not asking your prescriber to choose between your mental health and your physical health. You’re asking for a clinician who takes both seriously at the same time — which is a completely reasonable expectation and the standard that good psychiatric care should meet.
You are not necessarily asking to change medications. You may be. But the first goal is information: understanding whether the medication you’re on is likely to be contributing, whether alternatives exist, what monitoring should be happening, and what interventions might help within the context of your current regimen.
You are not asking for a diet plan. Medication-related weight changes are a clinical matter. They belong in a clinical conversation — with a prescriber who can examine the pharmacological picture, a pharmacist who can provide medication-specific guidance, and potentially an endocrinologist or obesity medicine specialist if the metabolic picture is complex.
Before the Appointment: What to Bring
The more specific you can be, the more useful the conversation will be. Before the appointment, it helps to have a sense of:
When the weight change began. If it correlates clearly with starting or changing a medication, that’s relevant clinical information. If it began before medications or is unrelated to medication timing, that’s also useful to establish.
How much weight has changed. A rough number is enough. The goal is to establish that this is clinically significant, not cosmetically bothersome.
What’s changed about your hunger and appetite. If you’re experiencing significantly increased appetite — particularly if it began with or after a medication change — that’s specific information. If you’re experiencing specific cravings for carbohydrates, disrupted satiety, eating at times or volumes that are uncharacteristic of your pre-medication baseline, all of this is clinically relevant and worth describing.
What metabolic labs you’ve had recently. Fasting glucose, HbA1c, fasting insulin, lipids, blood pressure. If you don’t know, ask. If they haven’t been done recently, request them. Metabolic monitoring is a clinical standard for anyone on atypical antipsychotics, mood stabilizers with metabolic effects, or long-term corticosteroids — and it’s frequently not done as consistently as guidelines recommend.
Questions Worth Asking Directly
Clinical appointments are short. Coming in with specific questions gets more useful answers than a general “I’ve been gaining weight and I’m not sure what to do.”
“Is there evidence that this specific medication causes weight gain, and if so, what mechanism is it working through?” This question establishes that you’re looking for clinical information, not reassurance — and it tells you immediately whether your prescriber is engaging with the pharmacological reality.
“Are there alternative medications within this class that have a lower weight gain risk and might be appropriate for my situation?” This is a specific, clinically answerable question. Not all medications in a class carry equal metabolic risk — and if your prescriber hasn’t raised this, raising it yourself opens a conversation that might have real options.
“What metabolic monitoring should I be receiving, and how often?” For atypical antipsychotics, guidelines typically recommend baseline fasting glucose, lipids, weight, and blood pressure at initiation, then at 3 months, and then annually. Knowing what should be happening puts you in a position to notice if it isn’t.
“Is there anything that can be added to the regimen that might mitigate the metabolic effects?” Metformin, for example, has evidence for reducing weight gain and improving insulin sensitivity in people on antipsychotics — and is sometimes used for this purpose even in people without diabetes. Topiramate is sometimes used as an adjunct for olanzapine-related weight gain. These are clinical options that exist and may be worth discussing.
“If I’m going to stay on this medication, what monitoring and support should be in place for the metabolic picture?” This frames the conversation as ongoing clinical management rather than a one-time decision — which is what it is.
When the Conversation Doesn’t Go Well
Not every prescriber engages with the metabolic consequences of psychiatric medication as thoroughly as they should. Psychiatry has historically been somewhat siloed from general medical and metabolic care, and some prescribers are less familiar with the pharmacological weight gain literature than their patients deserve.
If you raise the issue and are dismissed — told the weight gain is behavioral, or that nothing can be done, or that you just need to eat less — that’s not the end of the conversation. It may be the beginning of a referral. Obesity medicine specialists, endocrinologists, and clinical pharmacists all have clinical standing to engage with medication-related metabolic effects alongside a prescriber. You don’t have to solve the entire pharmacological picture in a single appointment with a single clinician.
You also have the right to a second opinion. If a medication regimen is causing significant physical health consequences and your current prescriber isn’t engaging with that as a clinical priority, finding a prescriber who will take both dimensions of your health seriously is a legitimate option — not disloyalty to your treatment, but appropriate advocacy for your full health picture.
What Not to Do
This needs to be said clearly, because it matters: do not stop or reduce psychiatric medication because of weight concerns without medical guidance.
Abrupt discontinuation of antipsychotics, mood stabilizers, and certain antidepressants carries real risks — including relapse, withdrawal effects, and destabilization of conditions that the medication was protecting against. The weight gain is real. The clinical reason for the medication is also real. Both things deserve appropriate attention. Managing them requires a clinician who can hold both simultaneously — not a unilateral decision made in the absence of support.
The goal of all of this is to bring the physical health consequences of your medication into the clinical conversation where they belong — not to undermine the mental health care that is keeping you well. Both matter. You deserve care that treats them that way.
