Although some women may abruptly stop having periods leading up to the menopause, many will notice changes in patterns and irregular bleeding.
Whilst this can be a natural phase in your life, it may important to see your healthcare professional to rule out other health conditions if other worrying symptoms occur.
Many women experience Abnormal Uterine Bleeding (AUB) during perimenopause. AUB is defined as bleeding that differs in frequency, regularity, duration or amount to your regular menstrual bleeding.  Changes to the menstrual cycle often carry no significant consequences ; however, they could have a range of causes. Although it may simply be a symptom of perimenopause, it is still sensible to raise the issue with your healthcare professional. A thorough history and physical examination will indicate the cause of uterine bleeding and help discern the need for further investigation and treatment.  Other investigations for abnormal uterine bleeding include a PAP Smear, Endometrial or Uterine Sampling (Endometrial Biopsy), a Vaginal Ultrasound (Echography) and routine laboratory testing.
