Hi, Birth control pills usually do not cause any direct kidney dysfunction. Hormonal pills can cause hypertension over the years in some women which can indirectly cause kidney problems. Cardiovascular or Liver dysfunction is a more common side effect of the drug.I would suggest you to take liver and kidney function test along with abdominal ultrasound to rule out any abnormalities. Abdominal pain or cramps can also occur with a newer hormonal pill. These symptoms will subside in the subsequent cycles as your body adjusts to the newer hormone levels. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Saranya Ramadoss, General & Family Physician
