Methods and apparatuses are provided for reducing sweat production via, for example, the removal, disablement, and incapacitation of sweat glands in the epidermis, dermis and subdermal tissue regions of a patient. In one embodiment, a method of treating a patient is provided which involves identifying a patient having a condition of excessive sweating, positioning an energy delivery device proximate to a skin tissue of the patient and delivering energy to sweat glands to halt secretion of sweat. The energy delivery device may include microwave delivery devices, RF delivery devices, and cryogenic therapy devices. Some embodiments may include using a cooling element for avoiding destruction of non-target tissue and/or a suction device to localize treatment at specific portions of the skin fold.
