Ovarian Cysts

Overview

The female reproductive system includes the ovaries, fallopian tubes, uterus, cervix, and vagina.

Ovaries are two almond-shaped organs located on either side of the uterus. They are responsible for producing eggs and releasing them during a woman's monthly cycle.

Sometimes, a fluid-filled sac, called a cyst, forms on or in an ovary. These cysts are quite common. In many cases, they cause no problems at all and disappear on their own within a few months. They're often painless and harmless.

However, sometimes cysts can become twisted (torsion) or break open (rupture). This can lead to pain, discomfort, and other symptoms. A twisted ovary can cut off blood supply, and a ruptured cyst can cause bleeding inside the abdomen. These situations can be serious and require medical attention.

Regular checkups, including pelvic exams, are important to detect any potential problems early. Knowing the warning signs of a serious cyst issue—like persistent or severe pelvic pain, unusual bleeding, or fever—is crucial for your health. If you experience any of these symptoms, it's vital to see a doctor immediately.

Symptoms

Many ovarian cysts don't cause any problems and disappear without treatment. However, a large cyst can sometimes lead to discomfort. You might experience:

  • Pelvic pain: This can be a dull ache or a sharp pain, sometimes coming and going, located on one side of your lower abdomen, below your belly button.

  • Feeling full, bloated, or heavy in your stomach (abdomen): This is a general feeling of fullness and pressure.

If you notice any of these symptoms, it's important to be aware of when to seek immediate medical attention:

  • Sudden, severe pain in your abdomen or pelvis: This is a crucial sign that requires quick medical attention.

  • Pain along with a fever or vomiting: These additional symptoms could indicate a more serious problem.

  • Signs of shock: These include a feeling of cold, clammy skin; rapid breathing; and lightheadedness or weakness. If you experience these signs, get immediate medical help.

When to see a doctor

Seek immediate medical attention if you experience:

  • Sudden, intense pain in your stomach or lower abdomen. This includes pain that comes on quickly and feels very strong.

  • Pain along with a fever or if you're throwing up (vomiting). Having pain accompanied by these symptoms can be a sign of a more serious problem.

  • Signs of shock. Shock is a serious medical condition that happens when your body isn't getting enough blood flow. Recognizing shock is important. Key signs include:

    • Cold, clammy skin: Your skin feels cool and wet to the touch.
    • Rapid breathing: You're breathing much faster than usual.
    • Lightheadedness or weakness: You feel dizzy, faint, or weak. You might feel like you're about to pass out.

If you notice any of these symptoms, don't delay. Call for emergency medical help right away.

Causes

Ovarian Cysts: Understanding Their Formation and Types

Ovarian cysts are fluid-filled sacs that can develop in the ovaries. They're quite common, often forming as a result of the normal monthly process of ovulation. Many cysts are harmless and go away on their own.

How Ovarian Cysts Form (Functional Cysts):

Your ovaries have tiny sacs called follicles that contain eggs. Each month, one of these follicles matures and releases an egg during ovulation. Sometimes, this process isn't quite smooth.

  • Follicular Cyst: Usually, the follicle wall breaks open to release the egg. If the follicle doesn't break open, fluid builds up inside, creating a follicular cyst. This often happens when the egg isn't released as expected.

  • Corpus Luteum Cyst: After releasing an egg, the follicle transforms into a structure called the corpus luteum, which produces hormones that support pregnancy. If the opening where the egg left closes off, fluid collects, forming a corpus luteum cyst.

Types of Ovarian Cysts:

Most cysts are "functional," meaning they're related to the normal menstrual cycle and usually disappear on their own. But other types exist:

  • Functional Cysts: These are the most common type, and usually cause no problems. They often resolve within a few menstrual cycles.

  • Dermoid Cysts (Teratomas): These cysts can form from cells that are meant to create eggs. They can contain various tissues, like hair, teeth, or skin. Most are not cancerous.

  • Cystadenomas: These cysts grow from the surface of the ovary and can be filled with watery or mucous-like material. They can sometimes grow quite large.

  • Endometriomas: These are related to endometriosis, a condition where tissue similar to the lining of the uterus grows outside the uterus. Sometimes, this tissue attaches to the ovary, forming a cyst.

Potential Complications:

Some cyst types, like dermoid cysts and cystadenomas, can grow large enough to push on the ovary or cause the ovary to twist (ovarian torsion). This twisting can cut off blood supply to the ovary and lead to pain.

Ovulation and the Menstrual Cycle:

Ovulation is the release of an egg from an ovary. It typically happens about halfway through the menstrual cycle, but the timing can vary.

Before ovulation, the lining of the uterus thickens to prepare for a possible pregnancy. The pituitary gland, a small gland in the brain, signals one of the ovaries to release an egg. The follicle's outer wall breaks, releasing the egg.

Tiny, finger-like projections called fimbriae guide the egg into a fallopian tube. The egg travels down the tube, potentially meeting a sperm for fertilization. If fertilization occurs, the egg and sperm combine to form a zygote. The zygote develops into a blastocyst, a cluster of cells that implants in the uterus, marking the beginning of pregnancy.

If fertilization doesn't happen, the egg is reabsorbed, and the uterine lining sheds, resulting in menstruation.

Risk factors

Ovarian cysts are more common in certain situations. Here are some factors that increase your risk:

  • Hormonal issues: Taking fertility drugs like clomiphene or letrozole (Femara) can sometimes cause your ovaries to produce more eggs. This increased activity can lead to the formation of cysts. Essentially, the ovary might have a harder time processing the egg production, resulting in a cyst.

  • Pregnancy: During pregnancy, the follicle (a small sac that holds the egg) that forms when you ovulate might not release the egg. Instead, it can stay on the ovary and potentially grow into a cyst. This is a relatively common occurrence.

  • Endometriosis: Endometriosis is a condition where tissue similar to the lining of your uterus grows outside of it. Sometimes, this tissue can attach to your ovary and form a cyst. This happens because the abnormal tissue responds to hormonal changes in the same way as the uterine lining, potentially leading to cyst formation.

  • Pelvic infections: If a pelvic infection spreads to the ovaries, it can cause inflammation and the formation of cysts. This is a serious situation, and prompt medical attention is vital.

  • History of ovarian cysts: If you've had an ovarian cyst in the past, you have a higher chance of developing another one in the future. Your body might be more prone to these occurrences.

In short, several factors can increase the likelihood of developing an ovarian cyst. If you have concerns, it's important to talk to your doctor.

Complications

Sometimes, ovarian cysts can cause problems. Here are two possible issues:

1. Ovarian Torsion: Large ovarian cysts can sometimes cause the ovary to twist. This is called ovarian torsion. When this happens, you might feel a sudden, sharp, and intense pain in your lower abdomen. You might also feel sick to your stomach (nausea) and throw up (vomit). Twisting the ovary can cut off the blood supply to it.

2. Cyst Rupture: If a cyst breaks open (ruptures), it can cause significant pain and bleeding in your pelvis. The risk of rupture is higher with larger cysts. Activities that put pressure on your pelvic area, like vigorous exercise or sexual activity, can also increase the chance of a cyst rupturing.

Prevention

Many ovarian cysts can't be prevented. However, regular checkups, like pelvic exams, are important. These checkups help doctors find any changes in your ovaries early.

Pay attention to changes in your monthly period. Keep track of any unusual symptoms, especially if they last longer than a few months. If you notice anything concerning, talk to your doctor. They can help you understand what's happening.

Diagnosis

Ovarian cysts can sometimes be found during a regular check-up of your pelvic area, or during imaging tests like an ultrasound. Doctors often need to figure out what kind of cyst it is and if it needs treatment, especially if it's large or contains solid material.

To determine the nature of the cyst, several tests might be necessary:

  • Pregnancy test: A positive pregnancy test could mean you are early in your pregnancy. Cysts related to the release of an egg (corpus luteum cysts) are common during pregnancy and usually aren't cause for concern.

  • Pelvic ultrasound: This test uses sound waves to create a picture of your uterus and ovaries on a screen. It helps confirm if you have a cyst, locate it, and see if it's filled with fluid or solid material. This helps doctors understand the cyst better.

  • Laparoscopy: This is a minor surgical procedure. A thin, lighted tube (laparoscope) is inserted into your abdomen through a small cut. This allows the doctor to directly view your ovaries and any cysts. If a cyst is found, treatment can often be done at the same time. Laparoscopy requires anesthesia.

  • Tumor marker tests: Sometimes, a blood test checks for levels of a protein called a cancer antigen. Elevated levels of certain cancer antigens (like CA 125) might suggest a possibility of ovarian cancer, especially if the cyst appears solid and you're at higher risk. However, these levels can also be high in other conditions, such as endometriosis or infections in the pelvis.

Less common types of cysts can also be found during a pelvic exam. If a solid cyst develops after menopause, it's important to be checked by a doctor as there's a small chance it could be cancerous. Regular checkups are crucial for early detection and appropriate management of any issues.

Treatment

Treating ovarian cysts depends on several factors: your age, the type and size of the cyst, and any symptoms you're experiencing. Your doctor might suggest different approaches:

1. Watchful Waiting: If you have a small, fluid-filled cyst that's not causing any problems, and an ultrasound confirms this, your doctor might recommend monitoring the cyst. This often involves getting follow-up ultrasounds over a few months to see if the cyst changes size or appearance. This option is usually suitable for people of any age.

2. Medications: Hormonal birth control pills can prevent ovulation. This can sometimes help prevent new cysts from forming. However, birth control pills won't shrink an existing cyst.

3. Surgery: Your doctor might recommend surgery for several reasons:

  • Large or growing cysts: If the cyst is large or getting bigger, it might need to be removed.
  • Cysts that don't look normal: Sometimes, a cyst doesn't look like a typical, harmless cyst. In these cases, surgery may be necessary to check it out.
  • Painful cysts: If the cyst is causing you pain, surgery may be the best course of action.
  • Suspicion of cancer: If there's a concern about cancer, surgery is often needed.

Surgical removal can be done in a few ways. A minimally invasive procedure called laparoscopy uses a small camera (laparoscope) and instruments inserted through small cuts in your abdomen. This method is often preferred for smaller cysts. For larger cysts or if cancer is suspected, a larger incision (open surgery) might be needed.

Important Considerations:

  • Post-Menopause: If an ovarian cyst develops after menopause, it's important to note that it sometimes could be cancerous. In these situations, you will likely need to consult a specialist in gynecologic cancers. Treatment in these cases may involve more extensive surgery, potentially including the removal of your uterus, cervix, fallopian tubes, and ovaries. Radiation therapy and chemotherapy might also be necessary.

Surgery is a serious decision, and your doctor will explain the best approach for your specific situation, taking into account your age, the cyst's characteristics, and your overall health. They will discuss the potential benefits and risks of each option with you.
