According to various embodiments of the present disclosure, an electronic device may comprise: at least one sensor, and at least one processor functionally connected with the at least one sensor. The at least one processor may be configured to: detect, through the at least one sensor, that a user of the electronic device is in a sleep state; based on detecting that the user is in the sleep state, obtain first biometric information through the at least one sensor; identify whether a first value indicated by the obtained first biometric information is decreased so that a difference between the first value and a second value determined based on first biometric information obtained in a designated state is greater than or equal to a designated value; based on identifying that the first value is decreased so that the difference between the first value and the second value is greater than or equal to the designated value, obtain second biometric information through the at least one sensor; and provide information related to sleep apnea based on the obtained second biometric information and second biometric information obtained in the designated state.
