Can abnormal uterine bleeding resolve on its own?

Whether abnormal uterine bleeding can resolve spontaneously depends on its cause and severity. Brief hormonal fluctuations or mild endometrial injuries may resolve on their own, whereas organic lesions or severe endocrine disorders are unlikely to self-resolve. If concerned, it is recommended to seek medical advice promptly. Detailed analysis is as follows:

If abnormal uterine bleeding is caused by temporary factors such as high stress, emotional fluctuations, or environmental changes, which lead to transient endocrine disorders, or by mild endometrial injury during the initial phase of intrauterine device placement, and the bleeding is short in duration and light in amount, it may resolve spontaneously. In such cases, once the triggering factors are removed, the body may self-regulate hormone levels back to normal, the endometrium heals, and the bleeding stops—for instance, in occasional mid-cycle bleeding that resolves without specific treatment.

When abnormal uterine bleeding is caused by organic diseases such as uterine fibroids, endometrial polyps, endometrial cancer, or polycystic ovary syndrome (PCOS), or by severe endocrine disorders, spontaneous resolution is unlikely. These conditions can cause irregular endometrial shedding, abnormal proliferation, or hormonal imbalances. Without timely intervention, the bleeding may persist or recur, potentially leading to complications such as anemia or infection. Treatment typically requires medication or surgical removal of the lesion to control the bleeding.

Timely medical consultation is essential when abnormal uterine bleeding occurs. Once the underlying cause is identified, targeted treatment should be implemented. Self-medication should be avoided to prevent delays in treatment. Maintaining a regular lifestyle, reducing psychological stress, and carefully monitoring the duration, amount of bleeding, and associated symptoms are recommended to facilitate accurate description during medical consultations.
