Objective: Epilepsy, one of the common neurological disorders, is a disease characterized by chronically recurrent seizures. In our study, we aimed to investigate whether there is a relationship between body mass index (BMI) increase and seizure types and its relationship with antiepileptic drugs (AEDs).

Material and Method: This study was created by prospectively analyzing the data of epilepsy patients who applied to a university hospital emer-gency department. The height, weight, and values of the patients included in the study, the number of years they had epilepsy, the AEDs they used, seizure type, and seizure duration were noted.

Results: According to BMI, 4.1% of our patients were underweight, 47.9% were normal-weight, 31.2% were overweight and 16.5% were obese. Generalized tonic-clonic (GTC) was the most common seizure type with 79.2%. We did not observe any significant difference in seizures between normal weight and obese patients. However, it was observed that complex partial seizure and myoclonic seizure type patients were of normal weight, while GTC and focal seizure type patients were overweight. No significant difference was observed between AED types and BMI.

Conclusion: In our study, we could not conclude if BMI difference increases or decreases epileptic seizures. However, we saw that BMI varies across seizure types. Since it is not clear whether obesity triggers epileptic seizures or whether the presence of epilepsy increases obesity, more comprehen-sive studies are needed.
