Pelvic pain, bloating, pressure, pain with sex, or sudden sharp discomfort can be frightening when you do not know what is causing it. Ovarian cysts are common, and many go away on their own, but some can cause symptoms that need medical attention. Understanding what ovarian cysts are, when they may be linked to endometriosis, and how treatment works can help you make confident decisions about your care.
The Endometriosis Treatment Center of America provides ovarian cyst evaluation and treatment in Lake Orion and Bloomfield Hills, MI. Led by Dr. Jonathan Zaidan, MD, FACOG, the team focuses on pelvic pain, endometriosis, robotic surgery, complete excision, fertility preservation, and pathology-backed answers when tissue is removed.
What Are Ovarian Cysts?
Ovarian cysts are fluid-filled sacs that grow on or inside an ovary. They can be very small or grow larger than 10 centimeters. Many women who menstruate develop cysts during their monthly cycle and never know they have one.
Most ovarian cysts are benign and do not increase the risk of ovarian cancer. They are also less common after menopause. While many cysts resolve without treatment, some can cause pain, bleeding, or other symptoms that a provider should check.
When Ovarian Cysts Cause Pain
An ovarian cyst is more likely to become painful when it grows large, bleeds, breaks open, affects blood flow to the ovary, or causes the ovary to twist. Twisting, also called torsion, can be serious and may cause sudden, severe pelvic pain.
Symptoms of ovarian cysts may include:
- Bloating or swelling in the abdomen
- Pelvic pain or pressure
- Dull, constant aching
- Pain shortly before or after your period begins
- Pain during bowel movements
- Pain with intercourse
- Pelvic pain during movement
- Sudden severe pain with nausea or vomiting
Sudden, intense pelvic pain, especially with nausea, vomiting, fever, dizziness, or heavy bleeding, should be treated as urgent.
What Causes Ovarian Cysts?
Ovarian cysts can develop for several reasons. Some are related to normal ovulation, while others are connected to hormonal changes, pregnancy, infection, or endometriosis.
Common causes include:
- Hormonal changes or ovulation-related cysts
- Medications that stimulate ovulation
- Early pregnancy cysts
- Endometriosis-related cysts, called endometriomas
- Severe pelvic infection that spreads to the ovaries or fallopian tubes
Endometriomas can cause pain during menstruation, pelvic pain, pain with sex, and fertility concerns. Because endometriosis can also cause pelvic inflammation and scar tissue, patients with ovarian cysts and pelvic pain may need a more complete evaluation.
How Ovarian Cysts Are Diagnosed
Diagnosis begins with a discussion about your symptoms, menstrual cycle, medical history, pain patterns, and fertility goals. Your provider may ask when the pain started, whether it changes around your period, and whether you have bowel, bladder, or sexual pain.
Testing may include a pelvic exam, ultrasound, imaging, lab work, or additional evaluation when endometriosis is suspected. If surgery is needed, tissue may be sent to pathology to provide clearer information about what was removed.
At The Endometriosis Treatment Center of America, this added documentation is an important part of patient transparency, especially when cysts are related to endometriosis.
Ovarian Cyst Treatment Options
Treatment depends on the type of cyst, size, symptoms, age, health history, and pregnancy goals. Some cysts may only need monitoring, while others require medication or surgery.
Treatment may include:
- Watchful monitoring with repeat imaging
- Pain relief options
- Hormonal medication when appropriate
- Evaluation for endometriosis or pelvic pain conditions
- Minimally invasive surgery for cysts that are large, painful, persistent, or suspicious
- Robotic surgery when complex pelvic care is needed
- Fertility preservation planning
When cysts are caused by endometriosis, complete excision of the endometriosis may be part of the treatment plan. The goal is to address the cyst while also considering the surrounding pelvic tissue, pain symptoms, and fertility needs.
Ovarian Cysts and Endometriosis
Not all ovarian cysts are related to endometriosis. However, endometriosis can cause endometriomas, which are cysts that form when endometriosis affects the ovaries. These cysts may be linked to painful periods, pelvic pain, painful intercourse, and trouble getting pregnant.
Because endometriosis can affect the ovaries, fallopian tubes, bowel, bladder, and pelvic structures, it is important to work with a team that understands complex pelvic pain. ETCA offers endometriosis services, pelvic pain treatment, fertility-focused care, and robotic endometriosis surgery when appropriate.
