A UK woman says her weight loss journey took an unexpected turn after using Mounjaro. While she successfully lost several stone, her breasts began growing instead of shrinking, despite her overall weight dropping significantly.
As the change became more noticeable, she researched her symptoms and consulted a doctor. She was diagnosed with gigantomastia, a rare medical condition that causes rapid and extreme growth of breast tissue. During her weight loss, her breast size increased dramatically, reaching a level where standard bras no longer fit.

The condition has led to daily physical discomfort. She experiences ongoing back pain, shoulder strain, numbness in her arms, and skin irritation caused by tight or unsuitable support. Wearing bras became so painful that she eventually stopped wearing them altogether to reduce injury and discomfort.
Doctors linked the unusual breast growth to her medical history and the timing of her weight loss treatment. To protect her health and reduce pressure on her back, she took further steps to manage her weight and prevent worsening symptoms. She is now considering breast reduction surgery as a long-term solution.

While living with constant physical challenges, she has focused on adapting to her condition and maintaining her quality of life. She continues to explore medical options, prioritising her health and long-term well-being while managing a rare and painful condition.
