Generally in a young person who is not overweight or a smoker, the hypertension is caused by genetic factors. Some people are just wired that way and it can develop at any time. It can also be secondary to other problems such as chronic kidney problems. Hormones play a factor and this is probably the hereditary part.
Because we can reduce some of the risk with a healthy diet, exercise and avoiding bad habits such as smoking and excess alcohol, we tend to think we can prevent all of it but in truth, a small percentage will still have it in spite of their best efforts. This doesn't mean you shouldn't continue to do these good things, since the bad lifestyle will make it worse and cause other problems. But, just realize that not everything can be prevented. You should take your blood pressure regularly to get a good picture of the average, since some fluctuation is normal.
You may need to take medication for high blood pressure for life. At least there are effective treatments. Your doctor will monitor and experiment with medications until you have the right one. Some people even require more than one to do the job since there are different categories of medications that can help.
After you become stabilized you will likely return every six months to be monitored. Whenever you take a diuretic it is important to have your labs checked regularly to be sure you don't lose other important electrolytes such as potassium and magnesium and you must drink plenty of water daily.
