The page https://partingtonps.com/why-do-my-breast-implants-feel-heavy-common-causes-explained/ offers expert insights into why breast implants may feel heavy, led by Dr. Marshall T. Partington. Post-operative swelling is a key factor, causing a tight, heavy sensation as tissues stretch, typically resolving within weeks. Larger implants, particularly silicone ones over 400cc, add significant weight, which can feel noticeable for patients with minimal breast tissue. An unsupportive bra post-surgery can worsen this by failing to distribute implant weight, increasing muscle strain. Capsular contracture, where scar tissue tightens around the implant, can lead to a heavy, firm sensation and may require surgery. Aging, pregnancy, or weight changes can alter breast tissue, contributing to a heavier feel over time. Implant displacement or leakage, though rare, can change weight distribution and cause discomfort. Patients with persistent heaviness, pain, or swelling should consult a surgeon promptly. Dr. Partington recommends supportive bras and adherence to post-operative care. Visit the page to understand these causes and how to address them.
