AF may be brief, with symptoms that come and go and end on their own. Or, the condition may be ongoing and require treatment. Sometimes AF is permanent, and medicines or other treatments can't restore a normal heart rhythm. The animation below shows atrial fibrillation. Click the start button to play the animation.
The hormones progesterone and estrogen play a significant role in fluid retention. When estrogen levels are elevated, women tend to retain more water than usual. This is why bloating is common in the days leading up to a woman's menstrual cycle - more estrogen means more water retention. During menopause, estrogen levels erratically fluctuate and bloating becomes more chronic.
Progesterone is used to cause menstrual periods in women who have not yet reached menopause but are not having periods due to a lack of progesterone in the body. It is also used to prevent overgrowth in the lining of the uterus in postmenopausal women who are receiving estrogen hormone replacement therapy.
