Endometriosis is a chronic, often misunderstood condition that affects millions of individuals worldwide, primarily women of reproductive age. It arises when tissue like the endometrium the lining of the uterus, begins to grow outside the uterine cavity. This ectopic tissue can be found on the ovaries, fallopian tubes, the outer surface of the uterus, and even on organs far removed from the reproductive system, such as the intestines or bladder. Although the precise cause of endometriosis remains unclear, it is generally thought to stem from a complex interplay of genetic, immune, and environmental factors (1,2). At its core, endometriosis is far more than a condition marked by pain; it is a multifaceted disorder that requires a comprehensive and nuanced approach to diagnosis and management. The condition forces society to reconsider the traditional understanding of what constitutes a "normal" menstrual cycle, urging a shift in the way we view menstrual health. To make meaningful strides in improving the lives of those affected, it is crucial to raise awareness, expand support systems, and accelerate research into the causes and potential treatments for endometriosis (3).

The hallmark symptom of endometriosis is severe pelvic pain, particularly during menstruation. However, for many individuals suffering from the condition, the pain extends far beyond what is typically expected from a period. This debilitating pain can significantly disrupt daily activities, often beginning before menstruation starts and intensifying throughout the cycle. In some cases, the discomfort persists long after menstruation has concluded. For these individuals, pain is not merely a monthly inconvenience and it becomes a chronic companion that infiltrates nearly every aspect of their lives, affecting not only physical health but also emotional and mental well-being (4,5).

Endometriosis is particularly insidious in that its symptoms are frequently minimized or dismissed as "bad period pain." Society has long conditioned individuals to accept severe menstrual discomfort as an inevitable, though unfortunate, aspect of the menstrual cycle. This widespread misunderstanding leads to many individuals suffering in silence for years, unaware that their experience is not typical, but rather indicative of a serious medical condition (6). Unfortunately, the lack of recognition and stigmatization often result in delayed diagnoses, with some individuals waiting a decade or more before receiving a definitive diagnosis. By that point, the disease may have advanced considerably, complicating both treatment options and outcomes (7).

The intensity of pain experienced by individuals with endometriosis varies widely. For some, the pain may be intermittent, while for others, it may be relentless and progressively worse over time. Descriptions of the pain often include sharp, stabbing, or throbbing sensations, and it may be accompanied by other distressing symptoms such as bloating, nausea, fatigue, and gastrointestinal disturbances like diarrhea or constipation (8). Beyond the physical manifestations, endometriosis can take a significant toll on mental health. The chronic pain and potential for infertility, both common consequences of the condition, can lead to feelings of frustration, anxiety, depression, and a sense of isolation (9).

The relationship between endometriosis and fertility complications further complicates the condition’s impact. It is estimated that between one-third and one-half of individuals with endometriosis face challenges with conception. The inflammation and scarring caused by the abnormal tissue growth can damage reproductive organs, leading to adhesions and impairing the processes of ovulation, fertilization, and implantation (10). However, it is important to note that not all individuals with endometriosis experience infertility and many are able to conceive and carry a pregnancy to term. Nevertheless, the potential for fertility issues adds another layer of emotional distress for those living with the condition (11).

Despite the widespread prevalence and significant impact of endometriosis, there remains a critical gap in public and medical awareness about the disorder. Advances in early detection and diagnosis have been slow, as current diagnostic methods are often invasive, such as laparoscopy. The lack of widespread understanding contributes to the continued stigma surrounding menstrual health, with endometriosis frequently downplayed or dismissed as an insignificant issue. Consequently, many individuals with endometriosis feel misunderstood, unsupported, and isolated, further exacerbating the emotional strain associated with the condition (12,13).

Treatment for endometriosis is highly individualized, depending on the severity of the condition and the patient's specific goals whether that is pain management, fertility preservation, or both. Available options include hormonal therapies, pain management strategies, surgical interventions to remove endometrial tissue, and in some cases, hysterectomy. However, no single treatment approach is universally effective, and the process of finding the most suitable treatment can be long and frustrating. Individuals with endometriosis often must become their own advocates within the healthcare system, which may not always prioritize their needs or provide adequate care (14,15).

Endometriosis is far more than a condition characterized by pain it is a complex, multifactorial disorder that challenges conventional understanding of menstrual health. The need for increased awareness, comprehensive support, and intensified research into the causes and treatments of endometriosis is critical to improving the lives of the millions of individuals affected by this often invisible and debilitating condition (16). The aim of this study is to explore the pathophysiology of endometriosis, improve early diagnosis techniques, evaluate current treatment modalities, and increase awareness about the significant impact this condition has on those living with it, both physically and emotionally.

Aim of the Study

The aim of the study was to investigate the underlying mechanisms of endometriosis, evaluate its diagnostic challenges, and assess the effectiveness of existing treatments.

Objective

The objective of the study was to explore the impact of endometriosis on physical, emotional, and reproductive health, while contributing to a greater understanding of its pathophysiology.

The study utilized a descriptive cross-sectional design, enabling a thorough investigation into the prevalence, symptoms, and broader impact of endometriosis on individuals’ physical and emotional well-being. This approach was specifically chosen for its capacity to gather robust quantitative data at a single point in time, providing a clear and concise snapshot of the experiences of individuals living with endometriosis. A total of 150 participants were selected for the study, all women between the ages of 18 and 45 who had been formally diagnosed with endometriosis. Participants were recruited from specialized outpatient clinics in gynecology and reproductive health at three prominent hospitals. The target population was diverse, encompassing women at various stages of endometriosis, thus allowing for a comprehensive analysis of the condition’s effects across different levels of severity.

Inclusion Criteria

The inclusion criteria specified that participants be women aged 18 to 45, with a confirmed diagnosis of endometriosis, either through laparoscopy or imaging studies. Additionally, individuals who had experienced symptoms directly associated with endometriosis, such as dysmenorrhea, pelvic pain, gastrointestinal disturbances, or infertility, were eligible to participate. All participants provided informed consent and voluntarily agreed to take part in the study, ensuring ethical standards were upheld throughout the process.

Exclusion Criteria

• Women with co-existing medical conditions that could confound the findings, such as:
• Pelvic inflammatory disease
• Uterine fibroids
• Other gynecological disorders
• Participants who had undergone hysterectomy, as this could significantly alter symptomatology and progression of endometriosis.
• Pregnant women, as pregnancy could influence the manifestation and course of endometriosis.
• Individuals who were unable to understand or complete the study’s survey due to language barriers.

Data Collection

Data collection was carried out using a structured, self-administered questionnaire, meticulously designed to capture quantitative data on a range of factors, including pain severity, quality of life, and other symptoms associated with endometriosis. The questionnaire incorporated validated measurement scales, such as the Visual Analog Scale (VAS) for pain assessment, as well as standardized instruments to evaluate the participants' quality of life and psychological health. The data collection phase spanned six months, ensuring a diverse and representative sample of individuals affected by the condition.

Data Analysis

Data analysis was conducted using exclusively quantitative techniques. Descriptive statistics were employed to summarize participant demographics and the frequency of various endometriosis-related symptoms. Inferential statistical methods, including chi-square tests and t-tests, were applied to examine the relationships between variables such as pain intensity, quality of life, and other relevant factors, including age and disease stage. This analytical approach allowed for the identification of significant patterns and trends, offering valuable insights into the profound impact of endometriosis on the lives of those affected.

Table 1: Demographic Characteristics of Study Participants

Table 1 provided a comprehensive overview of the demographic characteristics of the study participants, detailing their age, marital status, and employment status. Most participants were in the 26–35-year age group (43.3%), followed by those aged 36-45 years (33.3%) and 18-25 years (23.3%). This distribution reflected a typical cohort of individuals in their reproductive years. In terms of marital status, a significant proportion were single (46.7%), with married individuals comprising 40.0% and divorced individuals 13.3%. Employment status was diverse, with 66.7% of participants employed and 33.3% unemployed, offering insights into the socio-economic factors that may influence their experiences with endometriosis.

Table 2: Duration of Endometriosis Diagnosis

The duration of endometriosis diagnosis among participants was outlined in Table 2, revealing that 40.0% of individuals had been diagnosed for 1 to 3 years, and 30.0% had lived with the condition for 4 to 6 years. A substantial 16.7% of participants had been diagnosed within the past year, suggesting that some individuals may still be navigating the early stages of the disease. On the other hand, 13.3% of participants had been diagnosed for over six years, indicating a portion of the sample had dealt with the condition for an extended period before receiving a formal diagnosis. These findings underscored the often-delayed recognition of endometriosis.

Table 3: Prevalence of Symptoms in Study Participants

Table 3 highlighted the widespread prevalence of symptoms experienced by participants. Dysmenorrhea, or painful periods, was reported by 93.3% of participants, making it the most common symptom. Pelvic pain affected 86.7% of individuals, while fatigue was reported by 80.0%, further emphasizing the chronic and exhausting nature of the condition. Gastrointestinal issues, including bloating, were experienced by 73.3% of participants, and 33.3% struggled with infertility. These results demonstrated the multi-faceted nature of endometriosis, with symptoms impacting various bodily systems, resulting in a significant burden on individuals' physical and emotional health.

Table 4: Pain Severity Assessment

The assessment of pain severity, using the Visual Analog Scale, was presented in Table 4. It was found that 16.7% of participants reported mild pain (VAS score 0-3), 40.0% experienced moderate pain (VAS score 4-6), and 26.7% endured severe pain (VAS score 7-9). An additional 16.7% reported experiencing very severe pain (VAS score 10). These results illustrated the varied intensity of pain among individuals with endometriosis, with a substantial portion of participants enduring moderate to severe pain, which is consistent with the debilitating nature of the condition.

Table 5: Quality of Life Score

Table 5 summarized the quality-of-life scores of participants, revealing a significant impact of endometriosis on daily functioning. A considerable proportion of participants (30.0%) reported a very low quality of life score between 0-20, and 33.3% had scores between 21-40. Only a small percentage (3.3%) reported a high quality of life (score 81-100). These findings underscored the profound negative effect that endometriosis has on overall well-being, particularly in relation to pain, emotional distress, and physical limitations caused by the condition.

Table 6: Correlation Between Pain Severity and Quality of Life

In Table 6, the relationship between pain severity and quality of life was examined, revealing a clear inverse correlation. As pain severity increased, the quality of life significantly declined. Participants experiencing mild pain (VAS score 0-3) reported a mean quality of life score of 65.2, while those with very severe pain (VAS score 10) had a substantially lower mean score of 25.5. This data highlighted the debilitating effect of chronic pain on individuals’ daily lives, affirming the link between pain intensity and decreased overall life satisfaction.

Table 7: Statistical Analysis of Pain Severity and Symptom Duration

Table 7 explored the duration of symptoms in relation to pain severity, indicating that individuals who had been living with endometriosis for longer periods tended to report more severe pain. Participants with severe (VAS score 7-9) or very severe pain (VAS score 10) had been living with symptoms for an average of 4.2 to 5.0 years. In contrast, individuals reporting mild pain (VAS score 0-3) had a significantly shorter duration of symptoms, with a mean of 2.1 years. These findings suggested that longer symptom duration could be associated with more severe pain, highlighting the chronic nature of the condition and its progressive impact on the individual.

The findings from this study provided essential insights into the prevalence, severity, and profound impact of endometriosis on the daily lives of individuals living with the condition. The demographic characteristics of the study participants were consistent with trends observed in existing literature, reinforcing our understanding of the condition’s most affected groups. Most participants were aged between 26 and 35 years, reflecting the age range when endometriosis is most frequently diagnosed. This corresponds with previous studies by MacMahon et al, and Ferrero et al., that have consistently identified endometriosis as predominantly affecting women in their reproductive years, typically between the ages of 25 and 35 (17,18). Additionally, the 66.7% of participants who were employed further reflects findings from prior research by Missmer et al., suggesting that endometriosis impacts individuals across various socio-economic strata, regardless of employment status (19).

The duration of diagnosis in this study, with a significant portion of participants diagnosed between 1 and 3 years, closely mirrored the experiences documented in previous studies by Parasar et al., and it is widely acknowledged that endometriosis is often underdiagnosed or misdiagnosed, with women frequently enduring symptoms for several years before receiving a proper diagnosis (20). In this study, several participants had been living with endometriosis for over six years before diagnosis, which is consistent with findings from other research that report diagnostic delays averaging 6 to 10 years (5). This delay often leads to worsening symptoms, which underscores the need for more effective and timely diagnostic approaches.

Regarding symptom prevalence, the findings from this study align closely with those reported in numerous other studies on endometriosis. Dysmenorrhea (painful periods), pelvic pain, gastrointestinal disturbances, and infertility were among the most reported symptoms, confirming the multi-systemic nature of the condition. Dysmenorrhea was reported by 93.3% of participants in this study, which is consistent with earlier research by Moen & Schei that indicates menstrual pain affects between 80-90% of individuals with endometriosis (21). The prevalence of gastrointestinal symptoms, such as bloating and nausea, was reported by 73.3% of participants, echoing findings from studies that suggest 40-70% of individuals with endometriosis experience gastrointestinal issues. Similarly, the 33.3% of participants reporting infertility aligns with other studies estimating that 30-50% of women with endometriosis have trouble conceiving (22).

Pain severity emerged as a central finding in this study, with 40% of participants reporting moderate pain and 26.7% reporting severe pain. These results are in line with the extensive body of literature that shows pain is often the most debilitating aspect of endometriosis. Studies by Nisolle and Donnez have documented the widespread and chronic nature of pain in individuals with endometriosis, particularly moderate to severe pain that significantly interferes with daily life (23). This study further reinforces the notion that the intensity of pain is a major factor in the impairment of overall well-being, impacting work, social activities, and emotional health.

The impact of endometriosis on quality of life was also a key focus of this study, with a substantial number of participants reporting significantly reduced quality of life. Over 30% of participants scored between 0-20 on the quality-of-life scale, which aligns with studies that emphasize how endometriosis severely affects an individual’s physical, emotional, and social well-being. For example, Parazzini et al., found that women with endometriosis often experience a marked reduction in their quality of life due to chronic pain, fatigue, and the emotional burden of infertility (24). The inverse relationship between pain severity and quality of life in this study mirrors the findings of Sampson, who observed that higher pain intensity is directly correlated with a diminished quality of life in individuals with endometriosis (25). The impact of pain on overall life satisfaction is thus a central issue that warrants targeted attention in clinical settings.

Moreover, the study’s findings regarding the duration of symptoms and pain severity are consistent with previous research indicating that the longer an individual suffers from endometriosis, the more severe the pain tends to become. Participants with severe pain had been living with symptoms for an average of 4.2 to 5.0 years, which aligns with studies by Signorello et al., that suggest the progressive nature of the disease results in increasing pain intensity over time. These findings suggest that endometriosis, if left untreated or inadequately managed, can become more debilitating over the years, with symptoms intensifying as the disease progresses (26).

The results of this study resonate with and build upon previous research on endometriosis. The study highlights the chronic and debilitating nature of the condition, particularly in terms of pain severity and its detrimental impact on quality of life. Despite the widespread recognition of endometriosis, the condition continues to be underdiagnosed and poorly understood in many clinical settings, leading to prolonged suffering and delayed intervention. These findings underscore the urgent need for improved diagnostic tools, greater awareness, and more effective management strategies to alleviate the burden of endometriosis and enhance the lives of those affected.
