Can lack of food cause a teenager to have seizure like symptoms?

Yes. Eating disorders can cause seizures in both children and adults, but they are most common in teenage girls. Lack of nourishment to the brain can result in electrolyte imbalance, which can have a number of effects, including seizures. Additionally, the stress and anxiety associated with restricting food intake or purging also increase the risk of having a seizure for someone who is already prone to seizures. Finally, low blood sugar (hypoglycemia) is another potential cause of seizure that can occur in people with severe eating disorders.
