What is breast implant illness? Breast implant illness (BII) is the name patients and clinicians use for systemic symptoms that some people develop after getting breast implants. These include fatigue, brain fog, joint and muscle pain, hair loss, and rashes. It is not yet a formal diagnosis, and no single test confirms it. In published studies, most people who have their implants removed report that their symptoms improve.

At Venturis in Oklahoma City, our clinical team helps people with suspected BII look for other drivers of their symptoms, and supports them before and after explant surgery with a board-certified plastic surgeon. Book a free 15-minute discovery call to find out whether we are a good fit.

What breast implant illness is, and what the research says

Breast implant illness describes a set of symptoms that appear after breast implants are placed, with no other clear explanation. It can happen with silicone or saline implants, smooth or textured, and after cosmetic or reconstructive surgery. Some researchers group it under a broader category called ASIA, or autoimmune/inflammatory syndrome induced by adjuvants.

The FDA acknowledges the symptoms but has not defined the illness. Its analysis of reports filed between 2008 and June 2024 counted 10,318 reports of systemic symptoms in people with breast implants. The FDA says BII “is not recognized as a formal medical diagnosis and there are no specific tests or recognized criteria to define or characterize it.” Since 2021, the FDA has required a boxed warning and a patient decision checklist on breast implant labeling, and these mention systemic symptoms.

The research is growing, and it points toward a real effect. Here is what the larger reviews have found:

A 2025 meta-analysis of 33 studies (6,048 women) found that 81.9% reported improvement after explant. Symptoms began an average of 6.4 years after implantation. The authors concluded that BII is “a real, multifactorial clinical entity.”
A 2024 systematic review covering 39,505 implant patients found 83.5% improvement after removal in the studies that tracked it.
A 2026 prospective study followed women for 24 months after explant. Joint and muscle symptoms improved first, by about 3 months. Brain fog improved by about 6 months. Fatigue settled by about 12 months. Skin symptoms took 18 to 24 months.

There is still real disagreement. Large population studies have not shown a clear link between implants and defined autoimmune disease. Some plastic surgeons argue that the evidence does not yet support calling BII a syndrome. At Venturis, we take a middle path. Your symptoms are real and deserve a thorough workup, and that workup should rule out other causes before anyone points to the implants.

Breast implant illness symptoms

The most common symptoms are fatigue, joint and muscle pain, and brain fog. In a 2024 UK study of 100 women who had their implants removed for BII, the most common symptoms were fatigue (81%), aches and pains (72%), brain or memory fog (56%), mood changes (36%), nerve pain (28%), hair loss (28%), headaches (25%), digestive symptoms or food intolerances (24%), eczema or rash (18%), and vision changes (17%).

Researchers often sort these symptoms into four groups:

Symptom group	Common symptoms	Typical improvement after explant*
Musculoskeletal	Joint pain, muscle aches, stiffness, nerve pain	Within about 3 months
Neurocognitive	Brain fog, memory problems, headaches, anxiety, low mood	Within about 6 months
Constitutional	Fatigue, poor sleep, low-grade fevers or chills, night sweats	Gradually, settling by about 12 months
Skin and hair	Rashes, eczema, dry eyes and mouth, hair loss	Slowest, 18 to 24 months

*Based on a 2026 prospective study of 20 women (Bruno & Foti). Recovery varies from person to person.

People with BII also often report symptoms that overlap with dysautonomia and mast cell activation: a racing heart on standing, flushing, hives, new food or chemical sensitivities, and digestive upset.

Some symptoms need prompt attention from a surgeon or your primary care provider. These include new swelling, a lump, or fluid around one breast; a change in breast shape or a hardening capsule; or pain that appears years after surgery. These can signal rupture, capsular contracture, or rarely BIA-ALCL, an implant-associated lymphoma that the FDA tracks separately from BII.

Why breast implant illness may happen

No single cause has been proven. Researchers are studying four main explanations, and more than one may apply to the same person:

Immune activation. The body treats an implant as a foreign object and walls it off with a scar capsule. In some people, this triggers a lasting inflammatory response. The 2025 meta-analysis found capsule inflammation in 58.4% of BII cases and a positive ANA (an autoimmune marker) in about 24%.
Low-grade infection (biofilm). Bacteria can live in a thin film on the implant surface. One prospective study of 50 patients found chronic infection in 36% of explanted implants, and the meta-analysis reported a positive microbial finding in 35.2%.
Silicone gel bleed and rupture. Small amounts of silicone can migrate through an intact shell, and ruptures can go unnoticed for years. The meta-analysis put the rupture rate at 21.4% in its BII population.
Individual susceptibility. Researchers suggest that people with a personal or family history of autoimmunity, allergies, or immune sensitivity may be more likely to react.

BII often overlaps with other complex chronic conditions. Its symptom profile looks a lot like that of mold-related illness (CIRS), mast cell activation syndrome (MCAS), dysautonomia and POTS, long COVID, and fibromyalgia. Researchers who study ASIA have also described autonomic nervous system antibodies and small fiber neuropathy in these patients. This overlap matters for two reasons:

Another condition may be driving some or all of the symptoms. Explant alone would not resolve that.
More than one burden can stack up, such as implants plus a water-damaged home. Addressing only one may leave you partly better.

This is why we look at the whole picture first. Learn more on our mold and CIRS and MCAS pages.

How breast implant illness is evaluated

No blood test or scan can diagnose BII. Evaluation is a process of building a full picture and ruling out other causes. At Venturis, that process usually includes these steps:

A detailed history. When your implants were placed, their type and fill, any revisions, when symptoms began, and what else changed around that time, such as a move, an infection, pregnancy, or water damage at home or work.
Implant imaging, coordinated with your surgeon or primary care provider. The FDA recommends that people with silicone implants get an ultrasound or MRI starting 5 to 6 years after surgery, then every 2 to 3 years, to check for silent rupture.
Baseline lab work. This can include inflammation markers, autoimmune screening such as ANA, a thyroid panel, a metabolic panel, a blood count, and nutrient status. Results can show what is going on now, and they give you a baseline to compare against after explant. See our lab testing menu.
Screening for overlapping conditions. Depending on your history, this might include mold exposure and CIRS markers, mast cell markers, or an autonomic assessment.
A clear summary to take to your surgeon. You leave with organized findings to share with your plastic surgeon and other doctors.

The goal is not to talk you into or out of explant. It is to help you make that decision with full information.

Explant surgery and recovery support

Removing the implants is the step with the most evidence behind it. Across the reviews above, about 8 in 10 people report improvement after explant. A 750-patient study found that symptom scores dropped by about two-thirds within the first 30 days and stayed down. Explant is surgery, so it should be done by a board-certified plastic surgeon. Ask your surgeon whether they recommend removing the capsule as well (total or en bloc capsulectomy) in your case, and whether the implant and capsule will be sent for pathology and culture.

Improvement is common, but it is not guaranteed or instant. The UK study reported an average symptom improvement of 62%, not 100%. Its authors noted that explant “may not be curative.” Recovery also tends to be uneven, with pain easing before fatigue and skin symptoms catch up. People with an established autoimmune disease may respond differently from those with nonspecific symptoms.

How Venturis supports you:

Before surgery: We review your history and labs and screen for overlapping conditions. You get a plan for building your reserves ahead of the procedure, and a written summary to share with your surgeon.
After surgery: We repeat your labs to compare them with your baseline and track your symptoms by group over 3, 6, and 12 months. We support nutrition, sleep, and recovery, and we work on any remaining issues such as mold exposure, mast cell symptoms, or autonomic problems.
If you are not ready for surgery: We can still look for and address other drivers of your symptoms while you decide.

We do not perform explant surgery, and we do not offer any treatment as a substitute for it. Care at Venturis is personalized after a consultation and provided by the Venturis clinical team.

Frequently asked questions

Is breast implant illness real?

The symptoms are real, and the FDA has received more than 10,000 reports of them. BII is not yet a formal diagnosis, and its cause is still debated. A 2025 meta-analysis of 33 studies concluded that it is a real clinical entity with several contributing factors.

What are the first signs of breast implant illness?

Fatigue, joint or muscle pain, and brain fog are the most commonly reported early symptoms. On average, symptoms appear about 6 years after implants are placed, but they can start sooner or much later.

Can saline implants cause breast implant illness?

Yes. People report BII symptoms with both saline and silicone implants. Saline implants still have a silicone shell, and studies have not found that one implant type or surface is clearly safer for BII.

Is there a test for breast implant illness?

No single test confirms BII. Diagnosis rests on your history, on ruling out other causes, and on imaging to check the implants. Lab work helps rule out other conditions and gives you a baseline to compare against after explant.

Will my symptoms go away after explant?

Most people improve. Reviews report improvement in about 80% to 84% of patients, but not always completely. Joint pain often eases within weeks to months, while fatigue and skin symptoms can take a year or longer.

Should I have my capsule removed too?

This is a surgical decision to make with a board-certified plastic surgeon. Many BII studies used total capsulectomy, and the capsule can be sent for pathology and culture.

Is breast implant illness the same as BIA-ALCL?

No. BIA-ALCL is a rare lymphoma linked mainly to textured implants. It usually shows up as swelling or fluid around one breast. BII refers to whole-body symptoms. Any new swelling or lump needs prompt evaluation.

Can BII be confused with mold illness or MCAS?

Yes. The symptoms overlap heavily, and some people have more than one condition at the same time. Screening for these conditions is part of a thorough evaluation.

Does Venturis perform explant surgery?

No. Explant surgery is done by board-certified plastic surgeons. Venturis offers evaluation and supportive care before and after surgery, and for people who are still deciding.

Do you see patients outside Oklahoma City?

Yes. We serve Oklahoma City and surrounding areas, including Tulsa. A free 15-minute discovery call is the easiest way to start.
