A swollen nipple in a 13-year-old boy can be caused by a condition known as gynecomastia, which is common during puberty due to hormonal changes that result in an imbalance between estrogen and testosterone levels. It can also be a result of weight gain, certain medications, or underlying health issues. While it is often benign and temporary, it’s advisable to consult a healthcare professional for proper evaluation and reassurance.
