Hot flashes: Dear otter48565, it sounds as if your mom may be experiencing hot flashes. This tends to happen in women usually between the ages of 45- 55. During this time, female hormone levels decline enough to cause symptoms of hot flashes, night sweats, and insomnia. Encourage your mother to speak to her physician about treatments such as bio-identical hormone replacement to help her with her symptoms.
