I am 52 years old and just missed my period. This coincided with loose bowel movements and lower back pain on both sides. I have felt fatigued, had dizzy spells and increase in appetite. Is all this menopause? I only had 3 nights of profuse sweating, a year ago and no hot flashes. I cannot find any information anywhere on the loose bowels, lower back pain and. Menopause , so I am not sure.
