My blood pressure has been borderline recently
Some very good books available at amazon to help....
A machine at home is reassuring, as my readings are often lower when at home/relaxed.....
Eating foods high in potassium (bananas/apricots are high..) are good too,as they counteract sodium in your body...
Avoid salt/sodium at all costs.... any processed / fresh packaged food is normally laden with it... check your labels where poss.
Any meal with over 0.5-0.8g+ of salt is considered 'high' .
ANY water retention 'spikes' a BP reading, so try & 'p' prior to your appointment..
Mines just starting to come down following these guidelines, give it a try.... relax at the surgery....& good luck
