Lower abdominal pain in women occupies a diagnostic space that is more complex than it may initially appear. The lower abdomen houses not only the uterus, ovaries, and fallopian tubes, but also the bladder, the sigmoid colon, the rectum, the appendix, and the lower portions of the ureters. Pain arising from any of these structures can present as lower abdominal pain — which is why the specific character, pattern, and associated features of the pain are essential to directing the evaluation toward the right source.
For women of reproductive age, gynecologic causes are among the most common sources of lower abdominal pain — and among the most consistently missed or delayed in diagnosis. Endometriosis, fibroids, adenomyosis, ovarian cysts, and pelvic inflammatory disease each produce lower abdominal pain with characteristic features that a thorough clinical history can often distinguish from non-gynecologic sources. The evaluation at Lapeer Women’s Health is specifically designed to identify whether a gynecologic source is responsible — and when one is found, to offer the full range of appropriate treatment options.
This page covers the clinical patterns that most reliably indicate a gynecologic source of lower abdominal pain, the most common specific causes, and what a gynecologic evaluation involves. If your lower abdominal pain has not been adequately explained or treated, this page is the starting point for understanding whether a gynecologic evaluation is the missing step.
The following clinical features are associated with gynecologic causes of lower abdominal pain rather than gastrointestinal or urologic sources. Recognizing these patterns helps direct the evaluation toward the most likely origin.
- Lower abdominal pain that is consistently worse before or during the menstrual period and improves between cycles
- Lower abdominal cramping or aching that began at the same time as changes in menstrual pattern — heavier periods, irregular bleeding, or spotting
- A sense of lower abdominal fullness, pressure, or heaviness that is present regardless of bowel habits or dietary intake
- Lower abdominal pain accompanied by deep pelvic pain during intercourse
- Lower abdominal pain that is lateralized — consistently felt more on one side — suggesting adnexal involvement
- Lower abdominal aching accompanied by urinary urgency or frequency that follows a cyclical menstrual pattern
- Lower abdominal pain with fever, unusual vaginal discharge, or signs of infection
- Pain that has developed gradually alongside a visibly enlarged or changed lower abdomen
- Lower abdominal pain that has been attributed to gastrointestinal causes but has not responded to gastrointestinal treatment
- Persistent lower abdominal pain that began after a gynecologic procedure or pelvic infection
The most reliable indicator of a gynecologic source for lower abdominal pain is cyclicality — pain that predictably worsens with the menstrual period. In the absence of that pattern, other features including location, character, associated symptoms, and treatment response help direct the evaluation.
Most lower abdominal pain in women warrants scheduled gynecologic evaluation. The following patterns require more urgent attention:
- Sudden severe lower abdominal or pelvic pain unlike anything previously experienced — go to the emergency room
- Lower abdominal pain with fever, chills, or signs of infection — call our office the same day
- Lower abdominal pain in the context of a possible pregnancy — go to the emergency room immediately
- Severe lower abdominal pain with nausea, vomiting, or signs of shock — call 911
- Lower abdominal pain with heavy vaginal bleeding — call our office the same day

The following are the most common gynecologic conditions that produce lower abdominal pain. Each has characteristic features that help identify it — and each has effective treatments once accurately diagnosed.
Endometriosis
Endometriosis produces lower abdominal and pelvic pain through the cyclical bleeding and inflammatory activity of endometrial-like tissue outside the uterus. The pain characteristically involves the lower abdomen and deep pelvis, often radiating into the lower back and thighs. It is typically worse before and during menstruation, may be accompanied by deep dyspareunia, and worsens progressively over time. A normal pelvic ultrasound does not rule it out. It is one of the most consistently underdiagnosed causes of lower abdominal pain in women. Learn more about endometriosis →
Uterine Fibroids
Fibroids produce lower abdominal pain primarily through pelvic pressure and bulk — a persistent heaviness, fullness, or aching in the lower abdomen that is relatively constant rather than cyclical. Large fibroids or a significantly enlarged uterus may produce a visibly rounded lower abdomen alongside the pain. Menstruation may worsen the pain through uterine contractions against fibroid resistance. Fibroids are reliably identified on pelvic ultrasound. Learn more about uterine fibroids →
Adenomyosis
Adenomyosis produces a deep, diffuse lower abdominal and pelvic pain that is most intense during menstruation. The pain has a characteristic quality — described by many women as a sense of internal pressure or heaviness during the period that is deeper and more diffuse than typical menstrual cramping. It is frequently accompanied by heavy, prolonged periods and a tender, enlarged uterus on examination. It often coexists with endometriosis. Learn more about adenomyosis symptoms →
Ovarian Cysts
Ovarian cysts produce lower abdominal and pelvic pain that is often lateralized to the side of the involved ovary but may be perceived as diffuse lower abdominal discomfort when large. Endometriomas produce chronic pain that worsens cyclically. Functional cysts produce intermittent pain that often resolves with the natural regression of the cyst. Cyst rupture produces sudden pain. Ovarian cysts are identified on pelvic ultrasound and are one of the most reliably imaged causes of lower abdominal pain in women.
Pelvic Inflammatory Disease
PID produces lower abdominal pain with a subacute onset, accompanied by fever, cervical motion tenderness on examination, and often abnormal vaginal discharge. It reflects ascending infection from the lower reproductive tract to the uterus, tubes, and surrounding structures. Prompt treatment with antibiotics is essential to prevent the development of tubo-ovarian abscess and the long-term consequences of chronic pelvic pain and impaired fertility from adhesion formation.
Pelvic Adhesions
Adhesions from prior pelvic surgery, prior infection, or endometriosis produce lower abdominal and pelvic pain through the restriction of normal organ movement. The pain frequently has a pulling, positional, or activity-related quality that is distinct from the cramping or aching of most other gynecologic causes. Adhesion-related pain may be particularly noticeable with specific movements, position changes, or during physical activity that engages the lower abdomen and pelvis.
Non-gynecologic causes of lower abdominal pain — including IBS, inflammatory bowel disease, urinary tract infection, appendicitis, and musculoskeletal sources — should also be considered in any thorough evaluation. When clinical features suggest a gynecologic source, a gynecologic evaluation with pelvic ultrasound is the appropriate starting point. When the picture is mixed, a coordinated approach across specialties may be indicated.
Your evaluation is led by Dr. Ramona D. Andrei, MD, PhD, FACOG — with a systematic approach to identifying whether a gynecologic source is responsible for your lower abdominal pain and what the appropriate treatment is when one is found.
Step 1 — Focused Clinical History
Dr. Andrei reviews the character, location, timing, and pattern of your lower abdominal pain — with specific attention to its relationship to the menstrual cycle, associated symptoms, and prior evaluations. This history is the most important step in distinguishing gynecologic from non-gynecologic sources and directing the examination and imaging appropriately.
Step 2 — Pelvic Examination and Ultrasound
A pelvic examination assesses uterine size and contour, adnexal findings, pelvic floor tone, and specific tenderness patterns. Transvaginal ultrasound evaluates for fibroids, ovarian cysts, adenomyosis features, and other structural causes. This imaging step identifies or excludes the most common structural gynecologic sources of lower abdominal pain efficiently.
Step 3 — A Clear Explanation and Treatment Path
You leave your appointment with a clear explanation of whether a gynecologic cause was identified and what the recommended next steps are. If a gynecologic cause is found, treatment options are discussed in full. If the evaluation does not identify a gynecologic source, Dr. Andrei can discuss next steps for evaluating non-gynecologic contributing causes.
Lower abdominal pain that has been present for months, that has not responded to prior treatment, or that has been attributed to a diagnosis that never quite explained the full picture deserves a fresh evaluation with specific attention to gynecologic causes. For many women, the gynecologic evaluation — which includes pelvic examination and targeted ultrasound — is the step that was never taken before a diagnosis of IBS or a musculoskeletal cause was accepted as the final answer.
A single gynecologic appointment can answer the most important question: is there a structural or hormonal gynecologic source contributing to your lower abdominal pain? That answer — whether it confirms a gynecologic cause or appropriately redirects the evaluation — is worth having.
