Introduction

  • Menopause is when your periods stop due to lower hormone levels. This usually happens between the ages of 45 and 55.
  • It can sometimes happen earlier naturally. Or for reasons such as surgery to remove the ovaries (oophorectomy) or the uterus (hysterectomy), cancer treatments like chemotherapy, or a genetic reason. Sometimes the reason is unknown.
  • Perimenopause is when you have symptoms before your periods have stopped. You reach menopause when you have not had a period for 12 months.
  • Menopause and perimenopause can cause symptoms like anxiety, mood swings, brain fog, hot flushes and irregular periods. These symptoms can start years before your periods stop and carry on afterwards.
  • Menopause and perimenopause symptoms can have a big impact on your life, including relationships and work.
  • There are things you can do to help with symptoms. There are also medicines that can replace the missing hormones and help relieve your symptoms.
