How long does hormone therapy take to work for endometrial hyperplasia?

Endometrial hyperplasia means that the lining of the womb has become thicker than expected. Progestogen treatment can counter the effect of oestrogen on that lining. Bleeding patterns may change before the lining has fully responded, so a symptom change is not enough to confirm that the condition has settled.

Your clinician may review bleeding after an early treatment period and arrange a repeat sample of the womb lining, an examination, or an ultrasound according to your diagnosis. The plan differs when atypical cells are present, when symptoms continue, or when pregnancy is being considered. This condition is not the same as womb cancer, although some forms need careful surveillance.

Use tablets, a hormonal device, or another prescribed treatment exactly as instructed. Keep appointments for repeat assessment even if bleeding improves, and tell the clinician about missed doses or unexpected bleeding. Ask before using supplements or medicines that could affect bleeding. Learn more in [Endometrial Hyperplasia](/conditions/endometrial-hyperplasia/) and [Hormone Therapy for Cancer](/treatments/systemic-therapy/hormone-therapy-for-cancer/).

Contact your clinician if bleeding remains heavy, becomes more frequent, returns after improving, or causes tiredness or dizziness. Seek urgent help for soaking bleeding with faintness, severe pelvic pain, or sudden breathlessness. Unexpected bleeding after menopause should be assessed rather than attributed to treatment without advice.

Ask which type of hyperplasia you have, when the lining will be checked again, what bleeding pattern is expected, and what result would change the treatment plan. If fertility matters to you, ask how the treatment affects pregnancy planning and when that discussion should happen.
