The Truth About Breast Implant Illness and Its Symptoms
When Something Feels Wrong After Breast Implants
What is breast implant illness (BII) is a term used to describe a wide range of systemic symptoms — like fatigue, joint pain, brain fog, and anxiety — that some people develop after getting breast implants. It is not an official medical diagnosis, but it is a real concern reported by thousands of patients worldwide.
Quick answer:
| What it is | A collection of systemic symptoms reported after breast implant surgery |
| Who it affects | People with any type of breast implant — silicone or saline, ruptured or intact |
| Common symptoms | Fatigue, joint pain, brain fog, anxiety, autoimmune flares |
| Official status | Not a formal medical diagnosis — no specific test or diagnostic code exists |
| Does removal help? | In many cases, yes — 87.5% of patients who reported post-removal data to the FDA noted improvement |
Many women spend months — sometimes years — searching for answers. They see multiple doctors. Tests come back normal. Yet they still feel unwell. For a growing number of patients, breast implants are at the center of that mystery.
The FDA has received over 10,000 Medical Device Reports linking breast implants to systemic symptoms since 2008. And while science has not yet proven a direct cause-and-effect relationship, the volume of patient reports has pushed BII into serious medical conversation.
I’m Dr. Mark Anton, a breast surgery specialist with over 33 years of experience and thousands of breast surgeries performed — including complex revision cases where patients are navigating exactly the question of what is breast implant illness and whether it applies to them. In the sections below, I’ll walk you through what the research actually says, what symptoms to look for, and what your options are.

Understanding What is Breast Implant Illness
At its core, what is breast implant illness refers to a systemic condition where the body appears to react negatively to the presence of a breast prosthesis. While the term is widely used by patient advocacy groups and on social media, it is important to understand that it currently lacks a formal ICD-10 medical code. This means that when you visit a general practitioner, they may not find “BII” in their diagnostic manual.
However, clinical recognition is growing. Major health authorities, including the FDA and the Cleveland Clinic, now acknowledge that a subset of patients experience BII symptoms that can appear any time after surgery—sometimes immediately, and sometimes decades later.
Diana Zuckerman, PhD, president of the National Center for Health Research, notes that BII is a cluster of symptoms that often don’t fit into classic disease categories. She and other researchers believe that as data accumulates, it will eventually be recognized as a formal medical condition. At our practice in Newport Beach, CA, we see patients from all walks of life—the average age of those reporting symptoms to the FDA is roughly 42 years old—who are looking for a medical policy that prioritizes their systemic well-being over the aesthetic presence of the device.
What is Breast Implant Illness and How is it Diagnosed?
Because there is no “BII blood test,” diagnosing the condition is a process of elimination, often referred to as an exclusionary diagnosis. We start with a thorough medical history and physical examination to rule out other potential causes for your symptoms.
We often work alongside rheumatologists to check for autoimmune markers or conditions like Lupus or Rheumatoid Arthritis. If your tests for known diseases come back negative, but your breast implant illness symptoms persist, we begin to look at the implants as a potential trigger. It is vital to consult with a surgeon certified by the American Board of Plastic Surgery who has specific experience in Breast Implant Illness cases. A specialist will take your concerns seriously rather than dismissing them as “all in your head.”
Identifying What is Breast Implant Illness Symptoms in Patients
The symptoms of BII are incredibly diverse, affecting almost every system in the body. According to the FDA’s MDR database, which tracks medical device reports, the most frequently cited issues include:
- Fatigue (41.1%): A profound, “bone-tired” exhaustion that doesn’t improve with rest.
- Joint and Muscle Pain (30.9%): Aching in the limbs or back that mimics fibromyalgia.
- Anxiety and Depression (22.9%): New or worsening mental health struggles.
- Brain Fog (22.5%): Difficulty concentrating, memory lapses, or feeling “spaced out.”
- Autoimmune Mentions (22.6%): Flares of existing conditions or the development of new sensitivities.
Other reported Breast Implant Illness Saline Symptoms include hair loss, skin rashes, dry eyes, and gastrointestinal issues.
FDA Data and Medical Device Reporting
The FDA monitors the safety of implants through the Medical Device Reporting (MDR) system. Under 21 CFR Part 803, manufacturers and healthcare facilities are required to report adverse events.
Between January 2008 and June 2024, the FDA identified 10,318 unique MDRs specifically referring to systemic symptoms. The data reveals some eye-opening trends:
| Symptom Category | Percentage of Reports |
|---|---|
| Fatigue | 41.1% |
| Joint Issues | 30.9% |
| Anxiety | 22.9% |
| Autoimmune Mentions | 22.6% |
| Brain Fog | 22.5% |
The average time from implantation to the onset of these symptoms was approximately 5.6 years, though some patients reported issues within months. In response to this growing body of evidence, the FDA began requiring a “black box” warning on all breast implant packaging in 2021. This warning explicitly informs patients that breast implants are not lifetime devices and that some people have reported systemic symptoms.
The most encouraging statistic from the FDA’s review is that of the 785 reports that included post-removal information, a staggering 87.5% (687 cases) noted an improvement in their symptoms after the implants were taken out.
Potential Causes and Scientific Theories
Why do some women feel fine while others suffer? Scientists are currently exploring several theories regarding the “why” behind BII.
- Bacterial Biofilm: One of the most promising areas of research suggests that a bacterial biofilm that forms on the surface of the breast implant may trigger a chronic immune response. This microscopic layer of bacteria can live on the implant shell, keeping the body in a constant state of low-grade inflammation.
- Heavy Metals: Some theories suggest that heavy metals used in the manufacturing of the silicone shell or gel might “bleed” into the surrounding tissue. While studies have found trace amounts of metals like arsenic or zinc in capsules, many researchers argue these levels are often below regulatory limits and may also come from lifestyle factors like diet or smoking.
- Silicone Migration: Even if an implant hasn’t “ruptured,” microscopic silicone particles can sometimes migrate through the shell (a process called “gel bleed”) and settle in the lymph nodes or other organs, potentially causing a systemic reaction.
- ASIA Syndrome: Some experts link BII to Autoimmune/Autoinflammatory Syndrome Induced by Adjuvants (ASIA), where the immune system reacts to a foreign substance (the implant) acting as an adjuvant.
Whether it is the shell, the filler, or the bacteria on the surface, the body’s immune system is essentially “on high alert” 24/7. When patients report their symptoms to their doctors and to the FDA, they are often describing a body that is simply exhausted from fighting a foreign object.
Explantation and Recovery Options
For many women, the most effective Breast Implant Illness Treatment is surgical removal, also known as explantation.
A study published in Nature Scientific Reports in 2022 confirmed that a significant number of patients experience symptom relief after surgery. However, the type of surgery is a frequent point of discussion. You may have heard the term “en bloc” removal. This refers to removing the implant and the surrounding scar tissue (the capsule) together as one intact unit. Another common approach is a total capsulectomy, where the implant and capsule are both removed, but perhaps not in one single piece.
Interestingly, a study published in December 2021 found that the specific type of capsulectomy performed did not significantly change the rate of symptom reduction. Most patients improved regardless of whether the removal was “en bloc” or total, as long as the foreign material was gone.
Other studies have shown that Breast Implant Illness Recovery is a journey. While some symptoms like “brain fog” may lift almost immediately after BII Surgery, others like joint pain or autoimmune flares may take months to settle as the body’s inflammation levels return to normal.
Frequently Asked Questions about BII
Is BII the same as BIA-ALCL?
No, they are very different. Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL) is a rare type of T-cell lymphoma (cancer) that develops in the scar tissue around the implant. It is most commonly linked to textured implants. While BII is a collection of systemic symptoms, BIA-ALCL is a specific malignancy. However, both conditions have led to increased scrutiny of implant safety. If you have textured implants and notice sudden swelling or a lump, you should seek medical attention immediately. You can also Join the discussion Breast Reconstruction forum to hear from others who have navigated these diagnoses.
Do saline implants cause BII?
Yes. It is a common misconception that what is breast implant illness only applies to silicone-filled implants. FDA data shows that patients with saline implants also report systemic symptoms. It is important to remember that even saline implants have a silicone elastomer shell. Whether it is the shell itself or the body’s reaction to a foreign object, long-term health outcomes suggest that the filler type (saline vs. silicone) does not exempt a patient from the risk of BII.
How long does it take for symptoms to appear?
There is no set timeline. While the average onset is 5.6 years, some women feel ill within weeks of their Breast Augmentation Illness beginning, while others remain healthy for 20 years before symptoms emerge. This latent period makes it difficult to connect the dots, which is why medical device reporting is so critical for tracking long-term safety.
