A woman's nearly year-long struggle with severe, unexplained illness culminated in the discovery of life-threatening blood clots in her lungs, a condition she believes was triggered by hormones in her birth control.
In September 2025, the then-41-year-old marketing professional experienced severe heartburn and nausea, symptoms she initially attributed to a stomach virus. However, the persistent gastrointestinal distress, coupled with a hacking cough, led her to seek medical attention from her gastroenterologist. Despite medication for an acidic flare-up and anti-nausea treatment, her condition worsened.
By the ninth day of her illness, the woman was experiencing significant weight loss and a debilitating cough that disrupted her sleep and work. Hospital scans of her abdominal organs and bloodwork revealed no abnormalities, leaving medical professionals perplexed. On paper, she was a healthy individual who had recently been training for a half-marathon.
Escalating Symptoms and a Critical Diagnosis
Weeks passed with no improvement. The persistent nausea, lack of appetite, and coughing fits left her weak and increasingly concerned she was facing a serious illness like cancer or pneumonia. After a chest X-ray and a course of antibiotics and steroids proved ineffective, her symptoms took a dangerous turn. One morning, she awoke with severe chest pain and began coughing up blood.
Upon returning to the hospital, medical staff were unable to identify the cause of her distress, despite normal oxygen saturation and negative tests for flu, COVID-19, and RSV. A physician ordered a CT scan of her chest as a last resort. This scan revealed bilateral pulmonary embolisms—blood clots in both lungs.
The clots were identified as provoked by the hormones in her birth control. She was instructed to cease taking it immediately. The subsequent six months were dedicated to recovery, involving daily blood thinner medication, and consultations with specialists including a hematologist, cardiologist, and pulmonologist to manage the lung damage and prevent further clot formation.
Uncovering a Genetic Predisposition
Following her recovery from the immediate crisis, the woman underwent genetic testing. This revealed she has the prothrombin gene mutation, also known as Factor II. Carriers of this mutation have a significantly increased risk of developing deep vein thrombosis (DVT) or pulmonary embolism (PE) when using hormonal birth control or hormone replacement therapy.
Having taken hormonal birth control for over 20 years, initially for erratic cycles and later for pregnancy prevention, she considered the daily pill to be benign. While acknowledging that hormonal birth control carries risks of blood clots, she noted that for many individuals, these risks are low, emphasizing the importance of consulting a medical professional.
Armed with the knowledge of her genetic predisposition, the woman stated she no longer lives in fear of her body betraying her. She described regaining a sense of control over her health, finding a gift in the diagnosis that allowed her to move forward without the pervasive anxiety that had previously overshadowed her life.
