@athu While some people gain weight after starting an antidepressant, the antidepressant isn't always a direct cause. Many factors can contribute to weight gain during antidepressant therapy. For example:
Overeating or inactivity as a result of depression can cause weight gain.
Some people lose weight as part of their depression. In turn, an improved appetite associated with improved mood may result in increased weight.
Adults generally tend to gain weight as they age, regardless of the medications they take.
If you gain weight after starting an antidepressant, discuss the medication's benefits and side effects with your doctor. If the benefits outweigh the side effect of weight gain, consider managing your weight by eating healthier and getting more physical activity while enjoying an improved mood due to the medication.
