A single symptom does not prove oestrogen deficiency. Symptoms must be considered alongside life stage, menstrual cycle, medicines and overall health. A missed period also has various possible causes and is not automatically a diagnosis of hormone deficiency. [1]
Consider life stage and other causes
Menopause is an important context. However, cycle changes may also involve pregnancy, breastfeeding, significant weight changes, intense physical activity or medical conditions, for example. These possibilities should be distinguished before treatment starts. [1]
Which investigations are useful?
NICE explains that in otherwise healthy people aged 45 or over with typical menopausal symptoms, symptoms and menstrual history are often sufficient for assessment. An additional hormone measurement is then not automatically required. Younger people or unclear situations may need different investigations. This recommendation cannot be used as a universal rule for every age or hormonal treatment. [2]
As our suggested conversation aid, note symptoms, recent bleeding, hormonal contraception, other medicines and the greatest impact on daily life. A single number without this context does not replace medical assessment.
Choose treatment according to the specific goal
For menopausal symptoms, hormone therapy and other options may be discussed depending on the situation. Benefits and risks depend on age, medical history, product and route of use, among other factors. A general online recommendation for everyone is therefore inappropriate. [2]
For vaginal and urinary symptoms, NICE distinguishes local vaginal oestrogen from systemic hormone therapy. Non-hormonal moisturisers or lubricants may also be options depending on the goal. A history of cancer or contraindications makes an individual professional decision particularly important. [2]
Do not give bleeding a blanket explanation
Bleeding after menopause should be examined by a doctor, even if it is slight or happens only once. It may have different causes and should not be self-attributed to oestrogen deficiency. [3] Seek prompt medical help for unusually heavy bleeding, circulatory problems or severe pain. During hormone treatment, changes in bleeding should be discussed with the treating practice.
