If you’ve been prescribed gabapentin, you may have heard about its potential side effects, such as dizziness, fatigue, and nausea. But did your doctor mention the possibility of weight gain? Gabapentin is a medication commonly used to treat seizures, nerve pain, and anxiety disorders, but its effect on body weight is not well known. In this blog article, we will answer the question, “Can gabapentin cause weight gain?” and give you the knowledge you need to make an educated health choice.
Can Gabapentin Cause Weight Gain
Gabapentin is an anticonvulsant medication that works by slowing down nerve impulses in the brain. While it’s unclear how gabapentin affects body weight, evidence suggests it may cause weight gain in some people. The prescribing instructions for gabapentin list weight gain as a potential side effect.
Studies have shown that people taking gabapentin for conditions such as epilepsy and fibromyalgia may experience an average weight gain of up to 10 pounds. The weight gain may occur within the first few weeks of starting the medication and can continue over time. However, it’s important to note that not everyone who takes gabapentin will experience weight gain, and the amount of weight gained can vary between individuals.
It’s important to note that not everyone who takes gabapentin will experience weight gain, and the degree to which gabapentin affects body weight may vary from person to person. Other factors such as diet, exercise habits, and genetics may also play a role in determining whether someone experiences weight gain while taking gabapentin.
How Does Gabapentin Cause Weight Gain

The exact mechanism by which gabapentin causes weight gain is not well understood, but several theories have been proposed. One theory suggests that gabapentin may affect how the body metabolizes glucose, leading to insulin resistance and increased fat storage.
Another theory is that gabapentin may increase appetite and decrease physical activity, leading to increased calorie consumption and decreased calorie expenditure. People taking gabapentin may experience increased appetite or cravings for high-calorie foods, and they may also feel less motivated to exercise or engage in physical activity.
There is also evidence to suggest that gabapentin may affect the levels of certain hormones in the body that are involved in regulating appetite and metabolism. For example, gabapentin has been shown to increase hormone leptin levels, which signals to the brain that the body has enough energy stores and should stop eating.
Gabapentin Weight Loss
While gabapentin is known to cause weight increases, some individuals may experience weight loss while taking the drug. This is likely due to individual differences in how the body responds to the medication. However, weight loss is not a common side effect of gabapentin, and people should not expect to lose weight while taking the medication.

In some cases, gabapentin may be prescribed off-label for weight loss. However, this use of gabapentin is not supported by sufficient scientific evidence and is not recommended. Using gabapentin for weight loss may also carry additional risks, as the medication has not been specifically studied for this purpose and may interact with other medications or health conditions.
Conclusion
In conclusion, the question Can Gabapentin Cause Weight Gain is complex. While weight gain is a possible side effect of the medication, not everyone who takes gabapentin will experience this side effect. It’s important to talk to your doctor if you are concerned about your weight while taking gabapentin or any other medication. Your doctor may be able to adjust your dosage or switch you to a different medication that is less likely to cause weight gain.
If you experience weight gain while taking gabapentin, there are things you can do to manage your weight. Eating a healthy diet, exercising regularly, and monitoring your weight can help prevent or manage weight gain.
