Breast implant illness symptoms, what causes them, what explant surgery involves, and how to decide if removal is right for you.

Breast implant illness (BII) is a collection of systemic symptoms that some patients attribute to their breast implants. It is not yet a formal medical diagnosis, but it is a real and increasingly recognized phenomenon, one that the American Society of Plastic Surgeons and the Aesthetic Society are actively studying through a multi-year, long-term patient registry.
Patients with BII report a wide range of symptoms, which may include:
The symptoms are real. What is still being researched is the exact mechanism, whether it is an immune response, a low-grade chronic inflammatory reaction, microbial biofilm on the implant surface, or another process entirely. It is also unclear why some patients develop symptoms and others with the same implants do not.
There is no perfect predictor, but trends in the patient population suggest:
If you have implants and you are experiencing unexplained systemic symptoms that your primary care physician and specialists have not been able to attribute to another cause, BII is worth raising with a plastic surgeon.
Many of the symptoms associated with BII overlap with other conditions: thyroid disease, perimenopause, Lyme disease, anemia, sleep apnea, autoimmune disorders, and depression among them. A responsible explant conversation starts with making sure something treatable has not been missed.
A typical pre-explant workup might include:
This is not to talk you out of explant. It is to make sure that if you do proceed, you have maximized the chances that your symptoms actually resolve afterward.
Breast explant surgery is the removal of breast implants. Several approaches exist:
Simple implant removal. The implant is removed through a small incision, often the original scar. The capsule (scar tissue your body formed around the implant) is left in place.
En bloc capsulectomy. The implant and the entire surrounding capsule are removed as one intact unit, without rupturing or contaminating the surgical field. This is the approach many BII patients specifically request, and is recommended in certain cases such as ALCL surveillance or textured implant removal.
Total capsulectomy. The implant is removed first and the entire capsule is then meticulously removed, but not necessarily as one piece. Often equivalent to en bloc in terms of completeness.
Explant with lift (mastopexy). Many patients also need a breast lift at the time of explant, especially if the implants were large or in place for many years. The breast tissue and skin will not snap back to its pre-implant shape, and a lift restores a natural contour.
Explant with fat transfer. Fat from another area of the body is added to restore modest volume after implant removal, often combined with a lift.
This is the question every BII patient wants answered, and the honest answer is: most patients report improvement, but not all, and not always completely.
Research and patient reports suggest:
A surgeon who promises 100 percent symptom resolution is overselling. A surgeon who dismisses BII entirely is undereducated. Look for one who takes the symptoms seriously, talks honestly about probabilities, and has experience with explant patients.
Explant recovery is typically easier than the original augmentation:
Most patients are surprised that the physical recovery is straightforward. The emotional adjustment to a new breast shape, often softer, smaller, or different in projection, can take longer and is worth discussing with your surgeon in advance.
Ask:
Dr. Gillespie is double board certified and routinely performs explant procedures, including en bloc capsulectomy and explant with lift or fat transfer, at his Wilmington, DE practice. If you are considering removal, whether for symptoms, lifestyle change, or simply because you no longer want implants, schedule a consultation to discuss what is right for your situation.
