According to studies, antihistamines can be responsible for triggering weight gain. Well, there is still a huge lack of research and findings on the subject, however, the chemical structure of antihistamine is quite similar to weight gaining psychological medicines. Individuals who take antihistamines on a regular basis are found to be bulkier and obese than the ones who don’t. The association of heavyweight with antihistamines can also be due to the fact that they optimize the appetite of an individual which consequently stimulated weight gaining. More drowsiness and less physical activity can also be a reason for this side effect.
