Can Metoprolol Cause Weight Gain?


Metoprolol is a commonly prescribed medication from the beta-blocker class, used to treat various cardiovascular conditions such as high blood pressure, angina, and heart failure. While metoprolol is generally well-tolerated, there have been concerns about its potential association with weight gain. In this article, we will delve into the relationship between metoprolol and weight gain, factors that may influence weight changes, and strategies for managing weight while taking metoprolol.

Understanding Metoprolol

Metoprolol belongs to a class of medications known as beta blockers. It works by blocking certain receptors in the body, thereby reducing the effects of stress hormones like adrenaline. This results in lowered heart rate, reduced blood pressure, and improved cardiovascular functioning.

Metoprolol and Weight Gain: Exploring the Connection

Weight gain is a potential side effect associated with metoprolol use. While not everyone experiences weight gain, it has been reported by some individuals. The exact mechanism behind this side effect is not fully understood. However, there are several factors that may contribute to weight changes while taking metoprolol.

Factors Influencing Weight Gain on Metoprolol


  • Fluid Retention: Metoprolol can cause fluid retention, leading to temporary weight gain. This occurs due to changes in the body’s fluid balance, rather than an increase in body fat.
  • Slowed Metabolism: Some studies suggest that beta blockers like metoprolol may cause a slight decrease in metabolic rate, which could contribute to weight gain over time.
  • Lifestyle Changes: It is important to consider that lifestyle factors, such as dietary habits and physical activity levels, can play a significant role in weight management. Metoprolol itself does not directly cause weight gain, but changes in appetite or physical activity patterns may occur, potentially leading to weight fluctuations.

Managing Weight Gain on Metoprolol

  • Healthy Lifestyle: Focus on maintaining a balanced and nutritious diet, rich in fruits, vegetables, whole grains, and lean proteins. Engage in regular physical activity, such as walking or low-impact exercises, as approved by your healthcare provider.
  • Fluid Management: Discuss any concerns about fluid retention with your healthcare provider. They may recommend strategies to manage fluid balance, such as monitoring salt intake or adjusting medication dosages.
  • Regular Monitoring: Stay in close communication with your healthcare provider and have regular check-ups to monitor your weight and overall health. They can provide personalized guidance and support.

Metoprolol Succinate vs. Tartrate

It is important to note that both metoprolol succinate and metoprolol tartrate can potentially cause weight gain. The choice between the two formulations is typically based on the specific cardiovascular condition being treated and individual patient factors. Consult with your healthcare provider to determine the most suitable option for your needs.

Can weight gain on metoprolol be reversed?

Weight gain caused by fluid retention is generally reversible and may subside once the medication is adjusted or discontinued. However, it is crucial to consult with your healthcare provider before making any changes to your medication regimen.

Are there alternative medications that do not cause weight gain?

There may be alternative medications available that have a lower likelihood of causing weight gain. Your healthcare provider can discuss potential options based on your specific needs and conditions.


Weight gain is a potential side effect associated with metoprolol use, although it may not occur in everyone. Understanding the factors that influence weight changes and implementing healthy lifestyle habits can help manage weight while taking metoprolol. Remember to consult with your healthcare provider for personalized guidance and support throughout your treatment.

Take proactive steps in managing your overall health while on metoprolol. Maintain a healthy lifestyle, consult with your healthcare provider regularly, and prioritize open communication regarding any concerns or side effects. Remember, your healthcare provider is the best resource for personalized guidance and support. Consider exploring options for cost savings, such as prescription discount cards, to potentially reduce medication expenses.
