At a glance
Early menopause occurs from age 40 to 45. Premature ovarian insufficiency occurs before 40. Irregular or stopped periods at these ages need medical assessment. Hormone testing can be more useful here than at the usual menopause age.[9]
Why age changes the assessment
Jean Hailes distinguishes early menopause from premature ovarian insufficiency. These conditions can affect health beyond the symptoms you notice now. A doctor can investigate changes in periods, discuss the possible cause and consider further care.[9]
Testing before the usual menopause age
The advice that routine testing is unnecessary over 45 does not mean testing is never useful. Younger people with irregular or absent periods may need hormone investigations. The doctor decides which measurements and follow-up are needed; a single home test should not settle the diagnosis.[2]
Other explanations still matter
A change in periods can have several causes. RCPA describes investigations according to the clinical presentation, including pregnancy and other hormonal explanations. Tell the doctor about contraception, medicines and the timing of changes.[10]
Discuss longer-term health
Jean Hailes explains that early or premature menopause deserves care even when obvious symptoms are limited. Assessment can include discussion of bone and cardiovascular health, symptom management and emotional support. Your own history guides what needs attention.[9]
Prepare your questions
Record changes in your periods and any relevant family history. Ask what the tests are investigating, when results will be discussed and whether a specialist opinion may be useful. If fertility is a concern, mention it at the start of the consultation so it can be addressed.
Check service eligibility before paying
Some clinics publish age criteria or focus on care around the usual menopause age. Ask whether the service assesses symptoms before 40 or 45. Check referral requirements, appointment length and any laboratory charge. A missing age field in our table means it has not been established from the checked source.
