Hi, thanks for using healthcare magic
Hypertension can be classified as primary or secondary. Primary (there is no obvious cause) is more common, in younger persons like yourself , however, doctors would usually rule out a secondary cause before assuming it is primary.
To determine if there is a secondary cause blood are necessary to check for a variety of hormones, that if elevated ,can cause hypertension. In addition imaging is necessary - the abdomen specifically the kidneys at least.
A 24 hr urine collection to check for abnormal levels of hormones is also usually required.
If there is a secondary cause then this would have to be treated.
In primary hypertension
there is something called the DASH diet
which basically consists of low salt, reduction in alcohol, use of foods high in calcium and potassium, reducing in sodas and low fat foods as well.
Exercise and using prescribed medication is also advised
hope this helps
