Tomtit [17]
Emily's symptoms include frequent headaches, light sensitivity, nausea and vomiting. The risk factors are her smoking habit and the birth control pills that she is currently taking. A possible diagnosis could be an acute condition which is caused by a serious interaction between her smoking activity and her birth control pills. It has been proven that women who smoke while on contraceptive therapy have an increased risk of heart attack and stroke. This is because nicotine increases heart rate and blood pressure, while certain hormones present in some birth control pills (such as estrogen) increase the tension on blood vessels. For further diagnosis, the healthcare professional should check Emily's blood pressure and ask her family history on blood clots, heart problems, or stroke cases.
