Chapter I. Introduction to Abnormal Uterine Bleeding

The intricate symphony of the female reproductive system orchestrates a cyclic dance, marked by the rhythmic ebbs and flows of the menstrual cycle. However, amid this intricate ballet, a disruption emerges—a discordant note that reverberates as Abnormal Uterine Bleeding (AUB). This treatise endeavors to unfurl the layers of this multifaceted phenomenon, delving into its intricacies, ramifications, and the comprehensive landscape of understanding and managing this perplexing entity.

Abnormal Uterine Bleeding stands as a ubiquitous challenge, defying a singular definition in its manifestation. It echoes through the lives of countless individuals, transcending age, ethnicity, and socioeconomic backgrounds. Its impact, both physiological and psychological, resonates far beyond the confines of a clinical diagnosis, intricately woven into the fabric of everyday life.

This treatise embarks upon a journey through the corridors of anatomy, exploring the marvels of the female reproductive system and its nuanced orchestration. It navigates the tumultuous terrain of pathophysiology, dissecting the intricate interplay of hormonal, structural, and hemostatic elements that underpin the tapestry of normalcy and deviation.

Central to our exploration lies the mosaic of clinical presentations and symptoms—a panorama of menorrhagia, metrorrhagia, and their manifold permutations. Each symptom bears the potential to harbor a spectrum of etiologies, compelling us to decipher the labyrinth of differential diagnoses with precision and sagacity.

In our pursuit of clarity, this treatise unfurls the diagnostic armamentarium—where patient narratives intertwine with laboratory investigations and imaging modalities, guiding us toward an informed understanding and tailored interventions. We delve into the nuanced art of differential diagnosis, discerning between benign and malignant etiologies, gynecological intricacies, and systemic undercurrents.

Yet, beyond elucidating the complexities lies the crux—the pursuit of efficacious management strategies. From conventional pharmacotherapies to surgical interventions, and from lifestyle modifications to holistic approaches, this treatise navigates the landscape of treatment modalities. It contemplates the diverse needs of specific populations—adolescents, women traversing the tapestry of menopause, and those embracing the journey of motherhood.

As we venture forth into the vast expanse of research and future trajectories, this treatise aims to serve as a compass—a guiding beacon for clinicians, researchers, and individuals grappling with the enigmatic realm of Abnormal Uterine Bleeding. It echoes a call for further inquiry, innovation, and a collective endeavor to alleviate the burdens borne by those touched by this complex manifestation of the female reproductive continuum.

May this treatise stand as an edifice—a testament to our ceaseless quest for knowledge, understanding, and compassionate care in the realm of Abnormal Uterine Bleeding.

Definition and Classification of Abnormal Uterine Bleeding

Abnormal Uterine Bleeding (AUB) embodies a perplexing array of menstrual irregularities, defying a singular, succinct definition. It encompasses a spectrum of menstrual patterns deviating from the norm, characterized by alterations in frequency, duration, and volume of uterine bleeding. This chapter aims to unravel the intricacies of AUB, exploring its multifaceted nature through the lens of classification, delineating its diverse presentations, and laying the foundation for a comprehensive understanding.

Defining Abnormal Uterine Bleeding

At its core, AUB encompasses any deviation from the standard menstrual cycle, embracing a myriad of patterns that challenge the conventional norms of menstruation. It engulfs excessive bleeding (menorrhagia), irregular bleeding between periods (metrorrhagia), frequent or prolonged bleeding (menometrorrhagia), and intermenstrual bleeding, each presenting unique challenges in diagnosis and management. The defining criterion lies not merely in the quantitative aspects of bleeding but in its impact on the individual’s physical, emotional, and social well-being.

Classification of Abnormal Uterine Bleeding

AUB classification seeks to systematize the diverse manifestations, aiding clinicians in diagnosis, research, and therapeutic interventions. Several classifications exist, often drawing on etiological, anatomical, and temporal parameters to categorize AUB.

FIGO (International Federation of Gynecology and Obstetrics) Classification: This classification system delineates AUB into structural and non-structural causes. Structural causes encompass abnormalities within the uterus or reproductive tract, while non-structural causes encompass hormonal or systemic etiologies.

PALM-COEIN Classification: An evolution from the FIGO system, PALM-COEIN incorporates a broader spectrum of causes:

PALM stands for Structural Causes:

Polyp: Endometrial or cervical growths.

Adenomyosis: Presence of endometrial tissue within the myometrium.

Leiomyoma: Uterine fibroids.

Malignancy and Hyperplasia: Endometrial or cervical cancer, and hyperplastic conditions.

COEIN stands for Non-Structural Causes:

Coagulopathy: Bleeding disorders affecting clotting factors.

Ovulatory Dysfunction: Hormonal imbalances affecting ovulation.

Endometrial: Disorders like endometritis or atrophy.

Iatrogenic: Medication-induced bleeding abnormalities.

Not Yet Classified: When a definitive cause cannot be determined.

Understanding the Diversity of AUB Presentations

Menstrual patterns under the umbrella of AUB manifest diversely across individuals and phases of reproductive life. Menorrhagia, characterized by prolonged and heavy menstrual bleeding, often poses significant challenges due to its impact on a person's physical health and quality of life. Metrorrhagia, featuring irregular bleeding between expected periods, can be indicative of various underlying pathologies. Menometrorrhagia, a blend of excessive and irregular bleeding, creates a formidable clinical challenge, necessitating a thorough diagnostic approach.

Conclusion

In the mosaic of gynecological disorders, the spectrum of Abnormal Uterine Bleeding stands as a complex entity, transcending mere irregularities in menstrual patterns. Its classification provides a structured framework for clinicians, aiding in precise diagnosis, tailored management strategies, and a deeper comprehension of the underlying etiologies. As this treatise unfolds, further exploration into the nuances of each AUB classification will shed light on the intricate tapestry of this multifaceted condition, guiding clinicians towards more effective and patient-centric care.

Epidemiology and Prevalence of Abnormal Uterine Bleeding

The prevalence of Abnormal Uterine Bleeding (AUB) casts a pervasive shadow over the landscape of women's health globally. Understanding its epidemiology offers crucial insights into its burden on individuals, healthcare systems, and society at large. This chapter embarks on a journey through the prevalence, incidence, risk factors, and the demographic intricacies that define the epidemiology of AUB.

Prevalence and Incidence

The prevalence of AUB varies across different age groups and geographical regions, with estimates indicating a significant impact on reproductive-aged individuals. Studies suggest a prevalence ranging from 9% to 14% in the general population, encompassing a spectrum of menstrual irregularities that influence the lives of individuals in diverse ways.
