When i take my bp reading at home it ranges from 123/87to readings of 130/95 when i go to the doctors office i get a reading ranging from 118/79 to 150/100 should i take bp meds or change diet/ lifestyle? what causes my bp to raise at doctors office?

Normal BP: This is entirely normal. Nobody's BP is the same every time; it fluctuates with exercise, body position, food intake, and all sorts of other influences. Anxiety always raises BP, so often higher at doctor's office ("white coat hypertension"). Average BP over many measurements over days or weeks is what is important. If average <130 systolic (first number) and <80 diastolic (2nd no.), you're fine.
