The swell within: a rare case of type 1 hereditary angioedema.

We report the case of a 20-year-old woman who presented with facial swelling and recurrent abdominal pain. Subsequent evaluation confirmed a diagnosis of type 1 hereditary angioedema due to reduced levels of C1 esterase inhibitor. Timely diagnosis and personalized management significantly enhanced her overall well-being. The case highlights the need for heightened awareness of hereditary angioedema in patients with unexplained, recurrent angioedema and abdominal pain, facilitating timely intervention and optimal long-term outcomes.
