What are the specific causes of dysfunctional uterine bleeding?

Some women experience irregular uterine bleeding or abnormally heavy menstrual bleeding in daily life and are subsequently diagnosed with dysfunctional uterine bleeding (DUB), yet remain unaware of its underlying causes. So, what exactly causes dysfunctional uterine bleeding?

What Are the Specific Causes of Dysfunctional Uterine Bleeding?

The primary causes of dysfunctional uterine bleeding include psychological factors and adverse emotional stressors. These can disrupt the hypothalamic-pituitary-ovarian (HPO) axis, leading to abnormalities such as disordered gonadotropin-releasing hormone (GnRH) pulsatility, impaired feedback regulation, anovulation, and luteal phase insufficiency. Additionally, endocrine and metabolic disorders—including iron deficiency, anemia, aplastic anemia, and other hematologic conditions—may contribute.

Uterine and endometrial factors, iatrogenic causes (e.g., hormonal contraceptives), and intrauterine devices (IUDs) can all interfere with normal menstrual function. Moreover, women with poor nutrition or those who habitually follow unbalanced diets are at increased risk for developing dysfunctional uterine bleeding. Patients with DUB are advised to consume iron-rich foods. The associated anemia is typically hemorrhagic (i.e., iron-deficiency anemia); timely iron supplementation provides essential raw material for hemoglobin synthesis and helps elevate hemoglobin levels in the body.

Additionally, avoid excessively spicy foods, vegetables, and fruits, and ensure adequate protein intake—especially from red meat and lean meats. Furthermore, individuals experiencing symptoms should promptly seek medical evaluation and follow their physician’s guidance for appropriate management. We hope this information proves helpful!
