Can you please discuss definition of hypertension and describe causative factors?

BP above 140/90: Normal BP is below 120/80. BP between 120-139 systolic or 80-90 diastolic is prehypertension. BP at or above 140 or 90 is hypertension. Main causative factors are overweight, alcohol, too much salt, and genetics. You can be a thin non-drinker and still have genetic hypertension. Rare causes include some medications, and kidney or adrenal disease. Happy to answer any other questions you may have.
