Long-Term Mental Health Effects of Appetite Suppressants

Appetite suppressants can help with weight loss, but they may also impact mental health, especially for individuals with conditions like PCOS. While these medications aid in reducing hunger and managing weight, they can trigger side effects such as mood changes, anxiety, depression, and even dependency. Women with PCOS are particularly vulnerable due to pre-existing mental health challenges and hormonal imbalances. Long-term use carries risks like addiction, worsening of mental health conditions, and social or emotional difficulties.

Key Insights:

  • Short-Term Effects: Mood swings, insomnia, agitation, and rare cases of psychosis may appear within the first 12 weeks.
  • Long-Term Risks: Dependency, withdrawal symptoms, and exacerbation of existing mental health issues, such as depression or anxiety, are possible.
  • PCOS-Specific Concerns: Women with PCOS face higher rates of anxiety and depression, making careful monitoring essential.
  • Mental Health Support: Therapy, regular medical check-ins, and personalized care plans can help mitigate risks.

Bottom Line: Appetite suppressants can be effective for weight loss, but their mental health effects must not be overlooked. Professional guidance and mental health support are critical for safe and effective use.

Is This Weight Loss Drug Harmful to Your Mental Health?

Common Mental Health Side Effects

It's important to be aware of how appetite suppressants can affect mental health. These medications don't just influence physical appetite - they can also impact your mood, emotions, and overall psychological well-being, both in the short and long term.

Short-Term Mental Health Side Effects

When starting appetite suppressants, some psychological side effects can appear quickly - often within the first 12 weeks of use. These short-term effects can range from mild to severe and may disrupt daily life.

Mood changes are among the most frequently reported issues. Users often experience feelings of depression or anxiety, which can vary from a general sense of unease to more intense emotional challenges.

Cognitive effects are another concern. Some individuals report symptoms like agitation, confusion, or even, in rare cases, psychosis. These changes can interfere with work, relationships, and everyday activities.

Sleep problems, particularly insomnia, are also common. Poor sleep can worsen other mental health symptoms, creating a cycle that's hard to break.

GLP-1 medications, which are increasingly used to reduce cravings, come with their own psychological considerations. A 2024 KFF poll found that 12% of U.S. adults have used a GLP-1 drug. While these medications may help curb cravings, they can also lower dopamine levels, which might leave some users feeling emotionally "flat".

"These medications impact neurotransmitters, and so they can have an impact on mood. We've seen people who really feel like it boosts their mood, and I've seen others who feel like they struggle more with depression or irritability. It's definitely something that [health professionals] want to be assessing and monitoring and then treating if it comes up." – Amy Walters, PhD

Research shows that people with obesity using GLP-1 medications may face a slightly higher risk of anxiety and nearly double the risk of major depression. Additional symptoms can include mood swings, panic attacks, irritability, increased anger, and agitation.

Side Effect Category Specific Symptoms
Mood Changes Depression, anxiety
Cognitive Changes Agitation, delirium, psychosis
Sleep Disturbances Insomnia

Dependency and Withdrawal Symptoms

Over time, some users may develop a psychological dependency on appetite suppressants. This dependency often stems from fears of regaining weight, anxiety around eating, or distress at the thought of stopping the medication. For women managing PCOS, addressing this early is especially important to maintain both physical and emotional health.

A report found that 50% of people taking GLP-1 medications for obesity (not diabetes) stopped using them within a year. This highlights the challenges of long-term reliance on these drugs.

"In a perfect world, everybody on a GLP-1 would see a behavioral health provider because these medications are really impacting people's thoughts, emotions, and behaviors. And I mean: thoughts, emotions, behaviors." – Rachel Goldman, PhD

Addressing these issues requires open communication with your doctor. Early monitoring can help identify and manage psychological side effects before they escalate.

At Oana Health, we recognize the complex relationship between appetite suppressants and mental health, particularly for women with PCOS. Our licensed medical professionals provide personalized care and monitoring to help you safely navigate these challenges while staying on track with your health goals.

This underscores how essential medical supervision and tailored mental health support are when using appetite suppressants.

Long-Term Mental Health Risks

Long-term use of appetite suppressants can lead to profound and lasting changes in brain chemistry and behavior, posing serious risks to mental health. While short-term side effects are concerning, the long-term psychological impacts are often deeper and more challenging to reverse. Below, we explore some of the most pressing mental health risks tied to extended use.

Substance Use Disorders

Many appetite suppressants share stimulant-like properties, which can increase the risk of addiction and dependency over time. For instance, medications like phentermine influence neurotransmitters such as norepinephrine, dopamine, and serotonin, creating a sense of euphoria that can heighten addiction potential.

The statistics surrounding diet pill use are alarming. A University of Minnesota study revealed that by ages 19 to 20, 20% of girls had used diet pills, and nearly 62.7% of teenage girls engaged in unhealthy weight control behaviors. Additionally, up to 13% of women aged 15 to 59 have used or are using diet pills. Given that many appetite suppressants are classified as controlled substances, misuse becomes particularly dangerous, especially for individuals with a personal or family history of substance abuse.

The connection between eating disorders and substance abuse further complicates the picture. Research shows that up to 50% of people with eating disorders also use alcohol or illicit drugs - five times the rate seen in the general population. Conversely, 35% of individuals with substance dependency also struggle with eating disorders.

Effects on Existing Mental Health Conditions

For individuals with pre-existing mental health conditions, the risks of extended appetite suppressant use are significant. For example, people with bipolar disorder may face heightened risks: a retrospective review found that 40% of bipolar patients on mood stabilizers developed hypomania after using stimulants like amphetamine, methylphenidate, or modafinil.

Other conditions such as depression and anxiety can also worsen. One study indicated that individuals with obesity taking GLP-1 medications faced a slightly increased risk of anxiety and suicidal behavior, as well as nearly double the risk of major depression. Another study suggested that GLP-1 medications could exacerbate depression and trigger suicidal ideation in those with a genetic predisposition toward low dopamine function. Additionally, some appetite suppressants may interact negatively with antidepressants or anti-anxiety medications, increasing the likelihood of suicidal thoughts. Overuse of phentermine has even been linked to reversible psychosis in young, otherwise healthy individuals.

For women with PCOS, these risks are particularly concerning, as they already experience higher rates of anxiety and depression. This makes careful, ongoing monitoring essential.

Social and Emotional Problems

The long-term use of appetite suppressants can also lead to significant social and emotional difficulties. A relentless focus on weight loss can strain relationships, especially when social eating triggers anxiety or disrupts interactions with family and friends. Self-esteem may take a hit if weight loss goals are not achieved, compounding feelings of frustration and inadequacy.

Some individuals may also experience a "flat affect", where activities that once brought joy no longer feel rewarding due to diminished dopamine responses. The shared risk factors between eating disorders and substance use - such as genetic predispositions, trauma, low self-esteem, and societal pressures - can create a complex web of emotional challenges that complicate recovery. In some cases, disappointment over unmet weight loss goals may drive individuals to escalate their medication doses or switch between drugs, worsening both physical and psychological side effects.

For women with PCOS, these emotional and social challenges can be especially tough. Weight management is often a critical part of managing the condition, but the pressure to lose weight can sometimes mask the warning signs of problematic appetite suppressant use. Addressing these challenges requires a comprehensive approach.

At Oana Health, we understand the complexities of these long-term risks. Our licensed medical professionals work closely with you to create personalized treatment plans that address not only weight management but also the psychological aspects of PCOS care. This holistic approach helps you navigate the challenges of appetite suppressant use safely and effectively, while prioritizing your mental well-being.

How to Reduce Mental Health Side Effects

Appetite suppressants can pose risks to mental health, but with the right strategies, these effects can be managed. Regular medical supervision, professional mental health care, and tailored treatment plans are essential to addressing the unique challenges these medications may bring.

Medical Supervision Requirements

Close medical supervision is critical when using appetite suppressants to address concerns like misuse, serious side effects, and addiction. These medications can interact with other drugs, such as antidepressants or anti-anxiety medications, and may exacerbate conditions like high blood pressure or mood disorders. That’s why your healthcare provider plays a key role in ensuring your safety.

Some important practices include:

  • Regular check-ins to monitor both physical and mental health.
  • Detailed medication reviews to identify and prevent harmful drug interactions.
  • Mental health screenings during visits to detect early signs of anxiety, depression, or other concerns.
  • Open communication about any side effects, no matter how minor they seem.

Before starting any appetite suppressant, it’s important to have an honest discussion with your doctor about the potential benefits and risks. If you have a personal or family history of substance abuse, make sure to share that information, especially if you’re considering short-term stimulant-based suppressants. A collaborative, informed approach with your healthcare team ensures you receive the best care and helps you stay informed about your health choices.

In addition to medical oversight, incorporating mental health support can significantly improve your experience.

Mental Health Support Options

Professional mental health care can help manage the emotional and psychological challenges that sometimes accompany appetite suppressant use. Therapies like Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and Interpersonal Psychotherapy (IPT) are particularly effective for addressing thought patterns, managing stress, and tackling social pressures related to weight management.

Psychologists also play a critical role in providing support for individuals using GLP-1 medications or other appetite suppressants. They can help with improving body image, addressing body dysmorphia, coping with the loss of old habits, and dealing with societal pressures or emerging weight-related obsessions.

Here are some specific therapeutic approaches:

  • Body image therapy to address unrealistic expectations and body dysmorphia.
  • Grief counseling to process the loss of enjoyment from previous eating habits.
  • EMDR therapy for individuals who used food as a coping mechanism for trauma.
  • Nutritional counseling to ensure proper protein intake and prevent muscle loss.

"We can help patients become more knowledgeable. We can work with the emotional side of things, help support the health behavior change, screen and treat disordered eating behaviors that might develop, or address anxiety or depression that goes alongside it. We can help people develop a healthy relationship with food and a more comfortable relationship with their bodies while really promoting health at every size."

  • Amy Walters, PhD, Licensed Psychologist and Director of Behavioral Health

Addressing underlying mental health issues, such as anxiety or depression, can also alleviate eating disorders. This integrated approach ensures that emotional well-being is considered alongside physical health goals.

Personalized Treatment Plans

Tailored treatment plans are another important part of reducing risks associated with appetite suppressants. Since obesity is a complex condition, managing it often requires a combination of strategies, with appetite suppressants serving as just one piece of the puzzle. Personalized plans take into account your medical history, mental health, lifestyle, and specific goals.

For women with PCOS, for example, it’s essential to address both hormonal imbalances and mental health concerns together. At Oana Health, licensed medical professionals specialize in creating treatment plans that focus not only on weight management but also on the psychological challenges of PCOS. Through our telehealth platform, we provide ongoing monitoring and adjustments to ensure your mental health stays a priority.

This comprehensive approach allows you to safely navigate the challenges of appetite suppressant use while improving your overall health and well-being. By addressing both physical and mental health needs, you can reduce risks and achieve sustainable results.

Weighing Benefits Against Risks

Balancing the weight-loss benefits of appetite suppressants against their potential mental health risks is no simple task. Research paints a mixed picture: while some studies highlight impressive outcomes in weight management, others raise concerns about psychological side effects. Here’s a closer look at the key factors to consider when making treatment decisions.

Key Points to Keep in Mind

Let’s break down the benefits and risks:

Weight Loss Success Stories
Medications like phentermine-topiramate and GLP-1 receptor agonists are among the most effective options for shedding pounds. On average, they help users lose 6% to 11% of their body weight. When paired with a balanced diet and regular exercise, these drugs can lead to a 5% or greater reduction in starting weight. GLP-1 medications, in particular, have been noted for reducing "food noise", making it easier for some individuals to manage cravings and stay on track.

Mental Health: A Mixed Bag
The mental health effects of appetite suppressants vary widely. While some users report improved mood and reduced depressive symptoms, others experience heightened anxiety or irritability. Amy Walters, PhD, a psychologist at St. Luke's Humphreys Diabetes Center, explains: "These medications impact neurotransmitters, and so they can have an impact on mood. We've seen people who really feel like it boosts their mood, and I've seen others who feel like they struggle more with depression or irritability".

Challenges of Long-Term Use
Long-term use of GLP-1 drugs comes with uncertainties. Although 12% of U.S. adults have tried these medications, and many use them specifically for weight loss, discontinuation often leads to weight regain. In fact, half of those prescribed GLP-1s for obesity stop using them within a year. The full effects of prolonged use, especially injections, remain unclear.

The Need for Mental Health Support
Rachel Goldman, PhD, a clinical psychologist, underscores the importance of professional guidance: "In a perfect world, everybody on a GLP-1 would see a behavioral health provider because these medications are really impacting people's thoughts, emotions, and behaviors. And I mean: thoughts, emotions, behaviors. That's psychology, right?". Regular mental health monitoring can help address any emotional or behavioral changes that arise during treatment.

Next Steps for Women with PCOS

For women with PCOS, these findings carry even more weight. PCOS is often linked to significant mental health challenges, with anxiety affecting 28% to 39% of women and depression rates ranging from 11% to 25%. Additionally, women with PCOS are 4.23 times more likely to experience depressive symptoms compared to others. Since up to 80% of women with PCOS also struggle with obesity, effective weight management is crucial.

The key lies in working with healthcare providers who understand both the physical and emotional complexities of PCOS. A well-rounded team can assess how appetite suppressants interact with existing mental health concerns while addressing the hormonal and metabolic factors of the condition.

Oana Health offers specialized care for women with PCOS, focusing on both their physical and mental well-being. Their licensed medical professionals create tailored treatment plans that consider your unique risk factors, mental health history, and personal goals. Through their telehealth platform, Oana Health provides ongoing support to ensure your treatment plan promotes overall wellness without compromising mental health.

Choosing to use appetite suppressants is a big decision. By evaluating your health history, seeking professional guidance, and adopting a balanced approach, you can make choices that support both your body and mind.

FAQs

What are the potential mental health risks of long-term appetite suppressant use, especially for women with PCOS?

Long-term use of appetite suppressants can lead to serious mental health concerns, especially for women dealing with PCOS. These concerns may include anxiety, depression, and mood swings, which can be intensified by the hormonal and metabolic challenges already linked to PCOS. In some cases, individuals might also face cognitive difficulties, heightened agitation, or even develop a dependence on these medications.

Since women with PCOS are already more vulnerable to mental health struggles like depression and anxiety, it's important to approach appetite suppressants with care. If you're thinking about using these medications - or are already using them - it's essential to work closely with a licensed healthcare provider to keep both your physical and mental well-being in check.

What are the best ways to manage mood changes and other mental health effects while using appetite suppressants?

Managing the emotional ups and downs that can come with appetite suppressants starts with being mindful of how you're feeling. Pay attention to any changes in your mood or behavior, and make sure to discuss them with your healthcare provider as soon as possible. This way, your treatment can be adjusted to better suit your needs.

To help support your mental health, focus on a few simple but effective habits. Eat a nutritious and balanced diet, stay active through regular exercise, and try stress-relief practices like mindfulness or deep breathing. If you’re facing ongoing emotional struggles, it might be helpful to consult a mental health professional. Regular check-ins with your healthcare provider are also essential for tracking your progress and tweaking your treatment plan when necessary.

Why is mental health support and regular medical supervision important when using appetite suppressants for weight loss?

When using appetite suppressants, having access to mental health support and consistent medical supervision is crucial. These medications can sometimes trigger psychological side effects, like mood swings, heightened anxiety, or shifts in eating habits. Without proper oversight, these changes might go unnoticed, potentially affecting overall well-being.

Regular medical check-ups play a vital role in ensuring the medication is both safe and effective. They also help catch and address any side effects early on. By pairing professional medical guidance with mental health care, individuals can approach weight management in a way that supports both their physical and emotional health, minimizing risks along the way.
