Hi, Some studies have suggested that there is an association between taking the birth control pills and having mood swings and increased risk of depression. New research adds another potentially adverse psychological effect to the list that is impaired social judgement. Your body s levels of estrogen and progesterone fluctuate on their own, usually over the course of your menstrual cycle. When you start using birth control pills, the higher levels of these hormones in your body can make it easier to become annoyed, sad or angry. These because hormones like estrogen have a real, noticeable effect on your mood. Scientists found that women given high doses of estrogen were more likely to experience fear and anxiety than their peers. Other studies show that progestin hormones can induce irritability, depressed mood and anxiety when given to women. In short, the hormones in birth control probably won t affect you but if they do, they could make you feel more easily annoyed, depressed, anxious or angry than normal. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Zubayer Alam, General And Family Physician
