Allergic Conditions Linked to Higher Surgical Complication Rates, New Research Shows

Patients with common allergic conditions like eczema, asthma, and hay fever may face significantly increased risks of complications following surgery, according to research presented at the American College of Allergy, Asthma & Immunology (ACAAI) 2025 conference. The findings highlight the importance of proactive risk assessment and enhanced monitoring for this patient population.
The research suggests that the underlying inflammation and altered immune responses associated with these conditions can hinder the body’s natural healing processes and elevate the likelihood of post-operative infections. This increased vulnerability extends to a range of surgical procedures, including both reconstructive and restorative surgeries.
Increased Risks in Breast Reconstruction
A large-scale study focusing on breast reconstruction – a common procedure for women following cancer surgery – revealed a concerning trend. Researchers analyzed data from over 20,000 women and found that those with pre-existing allergic skin conditions, such as eczema or dermatitis, were demonstrably more likely to experience complications with their implants. These complications included infections, the buildup of scar tissue around the implant (capsular contracture), implant rupture, and ultimately, the need for implant removal.
“People with eczema or similar skin conditions already have more sensitive skin and a higher level of inflammation,” explained Philong Nguyen, BS, lead author of the breast reconstruction study. “That seems to make surgical healing more difficult and increases the chance of infection.”
The study further indicated that patients with atopic skin disease were more likely to require additional surgeries to address these complications over the three years following their initial reconstruction.
Bone Grafting Procedures Also Affected
The heightened risk isn’t limited to cosmetic or reconstructive surgeries. A second study, involving over 38,000 adults undergoing bone graft surgery – often used to repair or rebuild bone – demonstrated similar findings. Individuals with allergic conditions exhibited higher rates of infection, bone inflammation (osteomyelitis), and the need for further surgical intervention to remove or replace implants.
“Even two years after their initial surgery, people with atopic conditions were still more likely to have problems like infection or implant loosening,” stated Joshua Wang, MS, lead author of the bone grafting study. “These results suggest that allergic conditions can affect the body’s ability to heal after surgery – not just in the skin, but in the bones as well.”
Implications for Patient Care
The authors of both studies emphasize the critical need for increased awareness among surgeons and healthcare providers. Recognizing the elevated risk in patients with allergic conditions can inform more thorough preoperative counseling, allowing for a detailed discussion of potential complications and proactive mitigation strategies. Furthermore, the research underscores the importance of vigilant postoperative monitoring to detect and address any issues promptly.
The studies utilized robust methodologies, including propensity score matching to account for potential confounding factors such as demographics, comorbidities, and other treatment exposures. The breast reconstruction study analyzed data collected between 2002 and 2022, while the bone grafting study leveraged the extensive TriNetX research network. The findings consistently pointed to a statistically significant association between atopic disease and increased surgical complications.
These findings represent a crucial step toward optimizing surgical outcomes for a significant portion of the population. By acknowledging and addressing the unique challenges faced by patients with allergic conditions, healthcare professionals can work to minimize risks and improve the overall surgical experience.
