Primary vs. Secondary Hypertension

Wiki

Although poor diet, genetics, and other risk factors can increase a person’s likelihood of hypertension, most cases of hypertension have no clear cause. These cases are defined as primary hypertension. In a small percentage of cases, hypertension indicates the presence of another medical condition, such as kidney disorders, hormonal imbalances or drug use. In most cases, a search to determine the cause of hypertension is not economical or beneficial for the patient.

A combination of factors play a role in the rise of blood pressure in primary hypertension, including 
  • Genetics–some people are more susceptible to developing hypertension. This is a heritable trait.
  • Physical changes–such as those brought on by aging.
  • Lifestyle choices–such as a poor diet and lack of physical activity.
Secondary hypertension happens as a result of having another condition. Some conditions that may cause secondary hypertension are:
  • kidney disease
  • obstructive sleep apnea
  • congenital heart defects
  • problems with your thyroid
  • side effects of medication
  • use of illegal drugs
  • alcohol abuse or chronic use
  • adrenal gland problems
