Lexapro, a type of antidepressant prescribed to treat anxiety and depression, belongs to the category of selective serotonin reuptake inhibitors (SSRIs). This medication elevates serotonin levels in the body, as serotonin is the hormone responsible for feelings of happiness and tranquillity. Serotonin also impacts hunger and body weight, which is why increased serotonin production may lead to weight gain.
If your doctor has prescribed Lexapro, it’s important to understand the drug’s pros and cons. Based on that you can determine if Lexapro is the most suitable option for you. If you believe this medication is causing weight gain, and that in turn could cause anxiety, discuss with your doctor and inquire about alternatives.
How Could/Does Lexapro Cause Weight Gain in Patients?
Certain antidepressants are known to increase appetite and affect metabolism, potentially resulting in weight gain. Additionally, most individuals struggle to maintain an active lifestyle during depressive episodes, contributing to gradual weight gain over time. The precise mechanism through which Lexapro promotes weight gain still remains unclear. Many specialists believe that this specific side effect may be linked to a change in appetite. Other possible factors include increased fat accumulation due to reduced physical activity, as Lexapro can lead to low energy levels.
Let’s explore the three reasons behind Lexapro’s impact on weight:
- Increased Serotonin Levels:
Lexapro, an SSRI, raises serotonin levels to combat depression; and research indicates that elevated serotonin levels can influence weight. Elevated serotonin levels may lead to unwanted weight gain by altering patients’ appetites. This change in appetite may cause them to eat more, resulting in weight gain. - Increased Craving for Junk Food:
Another theory supported by researchers is that SSRI antidepressants like Lexapro might intensify cravings for unhealthy foods. Sugary beverages, carbohydrate-rich foods, and overly processed packaged foods can all hinder weight control. - Increased Appetite:
Some individuals tend to eat more when they are in a positive emotional state. Antidepressants like Lexapro alleviate feelings of depression and anxiety, potentially increasing one’s appetite as a result.
Cases of Weight Gain After Stopping Lexapro
Weight loss is another potential side effect of Lexapro, but it is experienced by very few people. These are often cases where weight gain is perceived as a withdrawal symptom after stopping Lexapro. There is only anecdotal evidence to support this, and it does not provide an explanation for why it occurs. Patients who do experience weight loss often notice this effect at the beginning of their treatment. One theory is that the end of the depressive episode may be the reason behind this weight loss. As serotonin levels rise and symptoms diminish, people may feel more energized and engage in more physical activity, resulting in weight loss. As it’s evident, this weight loss is not a long-lasting one – and is accompanied by a subsequent weight gain.
Lexapro Side Effects Can Contribute to Weight Gain
Like most SSRIs, Lexapro has side effects. Weakness, fatigue, and sleep problems are the most common side effects associated with Lexapro. All these issues can contribute to weight gain in patients. People dealing with these problems often turn to food as a means of feeling better. Additionally, these issues can affect metabolism, making it more challenging to burn calories.
Conclusion
Weight fluctuations, thus, are one of the most common side effects of Lexapro. SSRIs are known to cause long-term weight gain, with some patients experiencing only slight increases, while others notice more significant changes. To ensure that you have the most appropriate treatment plan, it is essential to consult a healthcare expert about any weight gain you may experience. Unchecked weight gain can lead to other health issues, including anxiety and stress. However, it is important not to discontinue the medication without consulting your doctor when experiencing weight gain, as abruptly stopping an antidepressant can lead to complications and harm your health.
FAQs
Will Lexapro cause immediate weight gain after starting it?
The experience of weight gain from Lexapro varies among individuals due to differences in physiology. Some may start to gain weight as soon as they begin taking the drug, while others may not notice any difference until a few months have passed. Extended use of Lexapro may increase the likelihood of weight gain in patients.
Can I prevent weight gain caused by Lexapro?
If you have experienced weight gain after starting Lexapro, it is not possible to prevent the occurrence of these side effects. However, as your body becomes accustomed to the medication and your metabolism returns to normal, this side effect may diminish and cease to cause further weight gain. Additionally, you can consider starting an exercise regimen and adopting a balanced diet to shed the extra weight gained from Lexapro.
