There is no corelation between weight and epilepsy. However, weight gain may cause your medication to be out of whack. Weight gain may cause your medication to be the wrong dosage.

I advise talking to your doctor if you have gained significant weight and your medication is not effective.

Some anticonvulsants can cause fatigue, if you get it alot your weight will increase due to lack of exercise, to prevent weight gain try to keep more active.

Exact opposite for me always chubby then suddenly went from size 13-15 to size 4. Just thought back in 1972 was from being at college no Mom food. Research into hormones in 1980s showed how high levels of either testosterone or estrogen speeds up both metabolism + brain rate. My own high level of estrogen always linked to why had epilepsy. Never gained weight from meds either. All have diff reactions to meds, cause all have diff bodies too.

There are medications that have side effects of Wieght gain

It’s not Epilepsy that causes weight gain . Although there are AED side Effects , that can cause weight gains and even weight loss .
