Blood pressure readings with a systolic pressure from 120 to 139 mm Hg or a diastolic pressure from 80 to 89 mm Hg, are considered prehypertension.
This condition is usually without symptoms, but, increasing in blood pressure values can be manifested with headaches and fatigue.
Prehypertension is likely to progress to hypertension overtime, and poses the same risks for heart diseases as hypertension.
30% of people with increased blood pressure experience rapid heart rhythm, or tachycardia.
It's true that women suffering from PCOS have greater chances to develop hypertension, diabetes and increased blood cholesterol levels.
The drug you use, medroxyprogesterone, is also related with hypertension and tachycardia as side effects.
