Ovarian cysts can sound scary at first—but the truth is, most are completely harmless. In fact, if you're a woman of reproductive age, chances are you've had one without even knowing it. Among the many types of ovarian cysts, the most common—and the least concerning—are simple ovarian cysts.
What Are Simple Ovarian Cysts?
A simple ovarian cyst is a fluid-filled sac that forms on the ovary. These cysts are typically part of the normal menstrual cycle. Every month, the ovaries produce follicles that may grow and release an egg. Sometimes, a follicle doesn’t release an egg or continues to grow—this can form a simple cyst.
Why You Shouldn’t Panic
Here are a few reasons you don’t need to worry about simple ovarian cysts:
1. They’re Extremely Common
Most women will develop a simple ovarian cyst at some point. These are especially common during childbearing years. In many cases, they come and go without symptoms and resolve on their own within a few weeks.
2. They’re Usually Small and Harmless
Simple cysts are generally small—often less than 5 cm in size—and filled with clear fluid. They have thin walls and do not contain any solid components. This makes them very unlikely to be cancerous or cause serious problems.
3. They Often Disappear Without Treatment
One of the defining features of simple cysts is that they go away on their own. Most doctors recommend a “watch and wait” approach. A follow-up ultrasound in 6–12 weeks often shows that the cyst has resolved completely.
4. They Rarely Cause Symptoms
Unless a cyst grows unusually large or ruptures (which is rare), it doesn’t usually cause pain or affect your health. You might not even know it’s there unless it’s found during a routine scan.
5. No Surgery Needed
Treatment is typically not needed unless the cyst causes discomfort or continues growing. In most cases, you won't need medication, and certainly not surgery. Hormonal birth control may sometimes be used to prevent future cysts, but that’s often unnecessary.
When to See a Doctor
While simple cysts are nothing to fear, it’s still wise to see a healthcare provider if you experience:
- Pelvic pain that doesn’t go away
- Bloating or feeling full quickly
- Changes in your menstrual cycle
- Pain during sex
Your doctor may recommend a pelvic ultrasound to evaluate the cyst. Simple cysts have a very typical appearance that’s easy to recognize on imaging.
Final Thoughts
Hearing the word “cyst” can make anyone uneasy—but simple ovarian cysts are a normal part of many women’s lives. Most are benign, temporary, and symptom-free. Regular checkups and communication with your healthcare provider can offer peace of mind and ensure everything stays on track.
Remember, not every bump on the road is a reason to hit the brakes—sometimes, it's just nature doing its thing.
