1. A method for providing information in an information processing system, the method comprising:
acquiring, via a network, biogas information representing a concentration of 2-ethylhexanoic acid of a user acquired by a sensor including a detector that detects the 2-ethylhexanoic acid discharged from a skin surface of the user and a controller configured to control said detector, wherein the controller is configured to control the detector to selectively detect the 2-ethylhexanoic acid from a mixture containing two or more kinds of substance;
obtaining reference information representing a lower limit of a normal range of the concentration of 2-ethylhexanoic acid per unit period of time, using a memory storing the reference information representing the lower limit of the normal range; and
outputting information related to stress of the user to an information terminal based on determining that a frequency with which the concentration of the 2-ethylhexanoic acid of the user per unit period of time is less than the lower limit of the normal range tends to increase, based on the biogas information acquired in a pregnancy period of the user.
