Menopause is much more than the end of menstrual periods. During perimenopause—the years leading up to menopause—estrogen and progesterone levels fluctuate before eventually declining.

Multiple Sclerosis (MS) is a complex and often unpredictable disease that affects the central nervous system. Despite extensive research, the exact cause of MS remains unknown. However, it's evident that hormones play a significant role in the progression and management of this condition. In this article, we explore how hormonal changes impact MS symptoms and disease progression, and discuss potential therapeutic approaches involving hormone therapy.

Hormonal Changes and MS

Hormonal changes can significantly impact the progression and symptoms of Multiple Sclerosis (MS). Here are key areas where these effects are most evident:

Pregnancy and MS

Many women with MS experience a reduction in disease activity during pregnancy, particularly in the third trimester. This is believed to be due to the high levels of pregnancy-related hormones, such as estrogen and progesterone, which may have protective effects…
