Does Xanax Cause Weight Gain? Examining the Potential Effects

Are you concerned about the possible weight gain associated with taking Xanax? You’re not alone. Many people who use this medication have questions about its potential side effects, especially when it comes to changes in their weight. In this informative blog post, we’ll dive into the connection between Xanax and weight gain, explore the drug’s potential effects on your body, and provide valuable tips for managing weight-related concerns. Let’s get started.

Let me first say, do NOT take Xanax recreationally. It can be extremely dangerous and I’ve seen people ruin their lives by taking Xanax and combining it with drinking. I even lost someone I knew who combined the two and didn’t wake up.  That’s my quick public advisory and I hope everyone surfing here is looking for information because they were actually prescribed this medicine.

Understanding Xanax and Its Uses

Before we delve into the relationship between Xanax and weight gain, it’s essential to understand what it is and why it’s prescribed. Also known as alprazolam, Xanax is a medication for anxiety and related conditions like panic disorder. It calms the nervous system by enhancing the effects of your brain’s neurotransmitter, GABA, and reducing anxiety.

Xanax and Its Potential Effects on Weight

Now that we have a basic understanding of Xanax and its uses, let’s examine the potential effects of this medication on weight. There are several ways that Xanax might influence your weight, both directly and indirectly.

Impact on Appetite

One way that Xanax might lead to weight gain is by increasing your appetite. Some people who take the drug report feeling hungrier than usual, which can lead to overeating and weight gain over time. Additionally, Xanax may cause changes in food preferences, making you more likely to crave high-calorie, sugary, or fatty foods.

Metabolic Changes

Metabolic changes are another possible effect of Xanax on your weight. This medication may slow down your metabolic rate, leading to burning fewer calories, especially at rest. Consequently, it makes it challenging to maintain or lose weight. In addition, this medication can impact insulin resistance, leading to weight gain and other conditions like type 2 diabetes.

Fluid Retention

You can also experience water retention, which causes a temporary weight gain since your body will retain more fluid than usual. While this weight gain is often short-lived, it can still concern those struggling.

Sedation and Fatigue

Xanax is known for its soothing effects, which can lead to feelings of drowsiness and fatigue. As a result, you will gain weight due to the following:

  • Reduced Physical Activity: When you feel sedated or fatigued, you are less likely to engage in regular physical activity or exercise. As a result, you burn fewer calories throughout the day, which can lead to weight gain over time, especially if your caloric intake remains the same or increases.
  • Changes in Energy Expenditure: Sedation and fatigue can also affect your body’s energy expenditure by reducing your non-exercise activity thermogenesis (NEAT). NEAT refers to the energy you burn during daily activities, such as walking, fidgeting, or doing household chores. When you’re feeling sedated or fatigued, you might be more inclined to sit or lie down, decreasing NEAT and, ultimately, weight gain.
  • Disrupted Sleep Patterns: Xanax can cause insomnia or poor-quality sleep, which has been linked to weight gain, as it can affect the regulation of ghrelin (the hunger hormone) and leptin (the satiety hormone). The imbalance leads to increased appetite and overeating, resulting in weight gain.
  • Impact on Daily Routine: Sedation and fatigue can disrupt your daily routine, making it challenging to maintain healthy habits such as meal planning, cooking nutritious meals, or participating in social activities that involve physical movement. This disruption can lead to relying on convenient, less healthy food options or engaging in more sedentary activities, which can contribute to weight gain.

Emotional and Psychological Effects

Taking Xanax may also have emotional and psychological effects that influence your weight. Statistically, 43% of adults facing emotional and psychological problems will likely gain weight. For example, the drug might temporarily alleviate anxiety, but it can also lead to emotional eating, as some people turn to food for comfort when they’re feeling stressed or anxious.

Managing Weight Gain While Taking Xanax

If you’re concerned about the possibility of weight gain while taking Xanax, there are steps you can take to minimize the risk and stay in control of your health.

Monitoring Your Diet

Paying attention to what you consume is essential for maintaining a healthy weight. It will help to incorporate lean proteins, vegetables, whole foods, and fresh fruits into your meals. If possible, limit your intake of sugary snacks and processed foods. Additionally, managing your portion sizes can be beneficial for maintaining your calorie intake and preventing excessive consumption.

Staying Physically Active

Staying Physically Active

Regular exercise is essential for maintaining a healthy weight and combating the potential weight gain from Xanax. To maintain a healthy weight, it’s recommended to engage in 150 minutes of moderate-intensity aerobic exercise per week. In addition, aim for 75 minutes of vigorous-intensity aerobic exercise each week.  You’d be shocked how many calories pickleball burns if you haven’t played it!

Seeking Professional Advice

Should you have concerns about potential weight gain while using Xanax, feel free to consult your physician for guidance. They can help you determine whether adjusting your dosage or switching to an alternative medication might be appropriate. Additionally, consider working with a nutritionist or personal trainer to develop a personalized diet and exercise plan tailored to your needs.


  • Does everyone who takes Xanax experience weight gain?

No, not everyone who takes Xanax will experience weight gain. The responses to the medication can vary widely depending on individuals. You may not notice any weight gain when taking Xanax.

  • What is the duration for weight gain to occur after initiating Xanax use?

There is no set timeline for weight gain associated with Xanax, as individual experiences can differ. Some people may notice changes in their weight within weeks of starting the medication, while others may not experience any weight gain at all.

  • Is it safe to stop taking Xanax if I notice weight gain?

It’d be best to consult your healthcare provider before changing your medication regimen. Abruptly stopping Xanax can lead to withdrawal symptoms and potentially worsen your anxiety or panic disorder. Your doctor will help you mitigate the risks of withdrawal.

  • Can I lose the weight gained while on Xanax after discontinuing its use?

Yes, it’s possible to lose weight gained while taking Xanax once you discontinue its use. However, working with your doctor to develop a safe and effective weight loss plan that considers your individual needs and overall health is crucial.


In conclusion, while there is a potential link between Xanax and weight gain, it’s essential to remember that individual experiences can vary. By staying proactive in managing your diet, exercise, and overall lifestyle, you can minimize the risk of weight gain while taking this medication. Always consult your doctor with any concerns about your weight or medication regimen, and remember that open communication with your healthcare providers is key to maintaining your well-being.
