Will I gain weight on sertraline?

Weight gain is a potential side effect of sertraline, but it does not affect everyone who takes the medication. The likelihood of weight gain may depend on individual factors such as genetics, diet, and physical activity levels.

Some studies have suggested that sertraline may cause modest weight gain in some individuals, typically less than 5 pounds. However, other studies have found no significant difference in weight gain between individuals taking sertraline and those taking a placebo.

It is important to note that weight gain is not a universal side effect of sertraline, and it may not occur in everyone who takes the medication. Additionally, any weight gain that does occur may be due to a variety of factors, including changes in appetite, metabolism, or physical activity levels, rather than the medication itself.

If you are concerned about the potential for weight gain while taking sertraline, it is important to talk to your doctor. Your doctor can help you monitor your weight and make recommendations for diet and exercise to help manage any potential changes in weight.

In conclusion, weight gain is a potential side effect of sertraline, but it does not affect everyone who takes the medication. The likelihood of weight gain may depend on individual factors, and any weight gain that does occur may be due to a variety of factors. If you are concerned about the potential for weight gain while taking sertraline, it is important to talk to your doctor and make lifestyle changes as needed to manage your weight.
