Im 28 w/extensive blood clot history now high blood pressure wht could cause high bp at my age? bp meds are not working

Need Workup: Hypertension is often genetic and it is not unusual to develop it under the age of 30. But there are other factors that should be considered. Some kidney diseases can cause blood clots and high blood pressure (lupus is one). Some medications can do the same (oral contraceptives). There are other factors (alcohol, obesity, adrenal disease) and medications that can increase BP without causing clots.
