Adenomyosis

Medically reviewed by the SEDU Clinical Review Board. Detailed pathophysiology, symptoms, and care guidelines.

Clinical Overview

A condition in which the endometrial tissue that normally lines the uterus grows into the muscular wall of the uterus (myometrium), leading to uterine enlargement and intense cramping.

Associated Symptoms

  • Menorrhagia (Heavy Menstrual Bleeding)
  • Chronic Pelvic Pain
  • Lower Back & Leg Pain
  • Severe Abdominal Bloating (Endo Belly)

Treatment Pathways

  • Combined Oral Contraceptive Pill
  • Lifestyle & Anti-Inflammatory Diet
  • Pelvic Floor Physical Therapy (PFPT)

Causes & Mechanisms

Uterine wall invagination during trauma (like childbirth, C-sections, or curettage) or local immunological deregulation causing endometrial basal layer invasion.

Risk Factors

Prior uterine surgeryChildbirthMiddle age (30-50)Short menstrual cycles

Diagnosis & Screening

High-resolution transvaginal ultrasound (shows asymmetrical myometrial thickening or subendometrial cysts) and MRI; histopathology post-hysterectomy is definitive.

Prevention & Care Guidelines

Hormonal suppression, endometrial ablation, uterine artery embolization, or hysterectomy for severe cases.

Frequently Asked Questions

Q:Is adenomyosis the same as endometriosis?

No. Endometriosis occurs outside the uterus, while adenomyosis occurs inside the muscular uterine wall, though they frequently co-exist.
