When individuals consider weight loss medication, they often consult specialists like endocrinologists or dietitians. However, psychiatrists can also play a crucial role in weight management, particularly when mental health issues are contributing factors. This article explores the role of psychiatrists in weight management, focusing on their ability to prescribe weight loss medications and how this fits into a comprehensive treatment plan.
The Role of Psychiatrists in Weight Management
Psychiatrists are medical doctors who specialize in diagnosing and treating mental health disorders. They possess a deep understanding of how psychological factors can influence physical health, including weight. Here’s how psychiatrists may be involved in weight management:
Addressing Mental Health Conditions: Mental health conditions such as depression, anxiety, and eating disorders can significantly impact weight, leading to either weight gain or loss. Psychiatrists can provide targeted treatment for these underlying conditions, which can indirectly support healthy weight management.
Managing Medication Side Effects: Certain psychiatric medications can cause weight gain as a side effect. Psychiatrists are equipped to adjust these medications, explore alternative options with fewer side effects, or provide additional treatments to manage medication-induced weight gain.
Implementing Behavioral Interventions: Psychiatrists often collaborate with patients to develop healthier lifestyle habits and effective coping strategies. These interventions can support weight loss or maintenance by addressing emotional eating and promoting healthier behaviors.

Can Psychiatrists Prescribe Weight Loss Medication?
Yes, psychiatrists can prescribe weight loss medications, even though it is not usually their primary focus. There are specific scenarios where a psychiatrist might consider prescribing these medications:
Comorbid Conditions: If a patient is already receiving treatment for a mental health condition and is also experiencing significant weight-related issues, a psychiatrist might incorporate weight loss medication into an integrated treatment plan to address both aspects of health.
Medication-Induced Weight Gain: If a patient experiences weight gain as a direct result of psychiatric medications, a psychiatrist may prescribe weight loss medications to counteract this effect, provided it is safe and appropriate for the individual’s health profile.
Collaborative Care: Psychiatrists may collaborate with primary care physicians or other specialists to deliver comprehensive care that includes weight management. In such cases, they might prescribe weight loss medication as part of a coordinated team approach.
Types of Weight Loss Medications
Weight loss medications approved by the FDA generally fall into two main categories: appetite suppressants and medications that affect absorption. These medications are typically intended for individuals with a body mass index (BMI) of 30 or higher, or a BMI of 27 or higher with weight-related health conditions.

Appetite Suppressants: Medications like phentermine work by reducing appetite, helping individuals to consume fewer calories. Phentermine is an effective and affordable anti-obesity drug with potent appetite suppression effects through the release of neurotransmitters, including norepinephrine, dopamine, and serotonin.
Absorption Inhibitors: Medications such as orlistat prevent the absorption of fats from the diet, thereby reducing overall calorie intake.
Considerations and Precautions
Before prescribing weight loss medications, a psychiatrist will conduct a thorough evaluation to ensure the medication is appropriate and safe for the individual, taking into account their specific health profile and mental health condition.
Comprehensive Evaluation: A comprehensive evaluation is crucial to determine if the medication is suitable for the patient's specific needs and to identify any potential risks or contraindications.
Monitoring and Follow-up: Regular monitoring is essential to assess the medication's effectiveness and manage any potential side effects. This includes tracking weight loss progress, monitoring vital signs, and addressing any concerns or adverse reactions.

Lifestyle Modifications: Medications are most effective when combined with lifestyle changes, such as improved diet and increased physical activity. Psychiatrists may collaborate with other healthcare providers to support these changes, offering a holistic approach to weight management.
The Connection Between Obesity and Mental Health
The relationship between obesity and mental health is complex and bidirectional. Mental illness can contribute to or worsen obesity, and conversely, obesity can contribute to or worsen mental illness. Conditions like depression, anxiety, and PTSD can affect eating behaviors, and many medications used to treat these disorders can cause significant weight gain.
People with mental health diagnoses may face additional challenges due to social isolation and stigma related to their weight, which can further exacerbate mental health issues. Overeating can sometimes serve as a form of self-medication, numbing or distracting from painful feelings and symptoms.
Integrating GLP-1s into Psychiatric Treatment
Glucagon-like peptide-1 receptor agonists (GLP-1s) such as semaglutide (Wegovy and Ozempic), liraglutide (Saxenda and Victoza), and tirzepatide (Zepbound and Mounjaro) have emerged as effective medications for weight loss. However, their impact on mental health is still being studied. While prescribing guidelines for some GLP-1s warn about the risk of suicidal thoughts and self-injury, research indicates a complex relationship between these medications and mental health.
Some studies suggest that GLP-1s may reduce the risk of suicidal ideation compared to other treatments for obesity or diabetes. Further research is needed to fully understand the psychiatric effects of GLP-1s and how they interact with mental health conditions.
Collaborative Care: Psychiatrists and Endocrinologists
Given the intricate connections between obesity and mental health, collaboration between psychiatrists and endocrinologists is crucial. Psychiatrists are learning that GLP-1s can be particularly effective for weight loss in patients with mental health disorders. With guidance from endocrinologists, some psychiatrists are beginning to prescribe these medications to their patients.
Weight loss achieved through GLP-1s can lead to improvements in mood, reduced anxiety, and increased self-esteem, ultimately enhancing the patient's quality of life.
Insights from a Retrospective Study on Phentermine
A retrospective study explored the use of phentermine for patients with obesity and co-existing psychotic or non-psychotic psychiatric conditions. The study found that phentermine was less effective in this population compared to the general population, possibly due to the counteraction between phentermine and antipsychotic medications or the orexigenic effects of antipsychotics.
However, the study also identified factors that could improve the effectiveness of phentermine in this population. Patients receiving anticonvulsant combination therapy (ACT), particularly with topiramate, showed a better response to phentermine. This suggests that appropriate combination therapy could help overcome the reduced effectiveness of phentermine in patients taking antipsychotic medications.
The study also highlighted the importance of monitoring for adverse events, as some patients discontinued phentermine due to intolerable side effects such as irritability, anxiety, and headache.
Key Takeaways
- People with serious mental health conditions have an increased risk of obesity.
- Weight changes can occur due to psychiatric medication, stigma, and other factors.
- A psychiatrist can help you maintain a healthy weight with medication. They may also recommend other supports, like therapy and lifestyle changes.
- The field of psychiatry primarily focuses on mental health. But it also addresses physical well-being. Some medications can have unwanted side effects, like possible weight gain. This can increase a person’s risk for obesity and cardiovascular disease.
What to Expect from Psychiatric Weight Management
Psychiatric weight management may help those with mental health conditions maintain a healthy weight. This can be especially important for people who are experiencing weight-related side effects from psychiatric medications. It can involve a combination of medication, therapy, and lifestyle changes. Throughout this process, your provider will be there to offer support and guidance.
If your psychiatrist prescribes a medication that can help with weight loss, you can expect occasional check-ins. They’ll want to monitor your progress, address side effects, and discuss how you’re feeling. Your provider can also offer alternative suggestions if something isn’t working.
In addition to taking medication, your provider will encourage you to care for your mind and body in other ways. For example, they may suggest eating a balanced diet and making time for regular movement. Your provider may also collaborate with other members of your care team to help you meet your goals. For example, they may connect with your primary care physician, nutritionist, or therapist.
