Hello, In my opinion, there is no reason to be worried and usually, this is just temporary and self-limiting. Excessive daytime sleepiness is common issues and should be considered in this case. Excessive daytime sleepiness may be caused by conditions such as sleep deprivation, metabolic disturbances, sleep apnoea, medications, neurological disorders such as seizures and psychiatric disorders such as depression. If emotional causes are ruled out then some tests can be done to confirm the diagnosis. In my opinion, polysomnography (sleep study), is one of the necessary examinations in order to achieve a correct diagnosis. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Ivan R. Rommstein, General Surgeon
