Welcome to HCM,
After going through your history,you suffered transient period of hyperacidity
which was treated but after your dizziness
and slight elevation of Blood Pressure persists.
I presume you are not taking any medicines for blood pressure right now.
140/90 mm of hg is borderline Pre hypertension/stage I, you should follow lifestyle modification and see if your BP comes back to normal range like:
Dietary change such as a low sodium diet
Regular physical exercise like brisk walk or outdoor sport.
If you are overweight
then reduce those extra kgs.
If smoking and alcohol use is there then stop both.
Stress reduction like practising Yoga and meditation
If inspite of these modification your BP is high then Medications for high BP
should be taken to keep BP at optimal level.
