Can Breast Implants Cause Fatigue, Joint Pain, or Brain Fog?

Can breast implants cause fatigue, joint pain, or brain fog?

People with implants have reported these symptoms, but current evidence does not establish whether or how they are related to implants. The FDA lists fatigue, brain fog, and joint or muscle pain among reported symptoms, with onset ranging from soon after implantation to years later.

The numbers need careful reading. The FDA reviewed 10,318 medical device reports from January 2008 through June 2024. Fatigue appeared in 41.1% of those reports, joint issues in 30.9%, and brain fog in 22.5%. Those percentages describe reports submitted to the FDA, not the share of all people with implants who experience symptoms.

“Breast implant illness” is a term patients use for a range of systemic symptoms. The FDA says it is not a formal medical diagnosis, and that no specific tests or recognized criteria define it. That uncertainty does not make a person’s symptoms imaginary; it means the symptoms alone cannot tell you what is causing them.

Online support groups can help you find language for symptoms and questions to raise. Treat stories as accounts of individual experience, not a way to predict your diagnosis or outcome. A useful next step is to bring a short symptom timeline to an appointment: when each symptom began, how it changes, and what evaluations you have already had.

Is there a test that can diagnose breast implant illness?

No specific test can diagnose breast implant illness, and there are no recognized diagnostic criteria for it. A test may still help investigate a particular symptom or identify another condition; it cannot, on its own, confirm that implants are the cause.

A clinical review in the Aesthetic Surgery Journal describes systemic symptoms attributed to implants as a diagnosis of exclusion. The authors recommend a thorough medical history and physical examination, plus a review of prior evaluations. Depending on the symptoms and examination, a clinician may consider tests such as a complete blood count, inflammation markers, electrolytes, kidney, thyroid or liver function, vitamin D, or calcium. Which tests make sense depends on the person; this is not a universal screening panel.

Make the appointment easier to use by stating the decision you need help with. For example: “I have these symptoms and implants. Can we review other possible causes before I decide whether to monitor or consider removal?” Then ask what each proposed test is meant to assess and what the next step would be if its result is normal or abnormal.

This approach keeps two questions separate: what could be causing the symptoms, and what should you do about the implants? A balanced evaluation can take the symptoms seriously without assuming the answer in advance.

What else should be ruled out when I have symptoms and implants?

Other potential causes of nonspecific symptoms should be assessed before they are attributed to implants. Fatigue, cognitive complaints, and joint pain can have more than one explanation, so the right evaluation depends on your history, examination, and previous results.

Bring a concise record rather than trying to solve the cause alone. Include the symptoms that interfere most with daily life, when they began, whether they fluctuate, medications or relevant health changes, and any prior test results. Ask your clinician: “What other explanations fit this pattern, and what would help us check them?”

If you are considering removal, separate the medical evaluation from the surgical decision. The FDA says implants are not lifetime devices and patients should expect that additional surgeries may be needed. For silicone gel implants, clinicians may recommend regular MRI or ultrasound to check for rupture and other complications; screening may not be covered by insurance. Ask your care team what monitoring applies to your implant and situation.

Removal is also a choice with tradeoffs, not a guaranteed treatment. In the FDA’s review, 785 reports included information about symptoms after removal: 687 reported improvement, while 98 reported no improvement or worsening. These are passive reports, which cannot establish how common outcomes are among all patients or prove what caused a change.

A prospective study published in the Aesthetic Surgery Journal followed 150 participants, including 50 symptomatic people who attributed symptoms to implants and requested removal. At six months, 94% of that symptomatic cohort reported at least partial improvement. A later report found at least partial improvement for 88% at one year. The authors note that changes in expectations or a nocebo effect could contribute; improvement after surgery does not prove the implants caused symptoms.

Ask the surgeon what removal would involve, whether replacement is an option you want to discuss, and what cosmetic changes could result. The FDA lists possible changes after removal without replacement, including dimpling, chest-wall concavity, puckering, wrinkling, or tissue loss. Discuss the risks, recovery, costs, and insurance coverage before making a decision. The FDA also requires a patient decision checklist to be reviewed with prospective patients; ask for clear explanations of risks, benefits, and device information.

Be specific about the surgical technique you are asking about. In the six-month study, symptom improvement did not differ significantly between intact total, total, and partial capsulectomy groups. The authors did not find support for requiring en bloc removal for self-reported systemic symptoms, and noted that intact total capsulectomy may carry higher risks. Ask your surgeon what is indicated for your individual case and why.
