Hi, Thanks for using HCM.
BP of 140/80 and 150/90 means it is fluctuating. Just check for BP at regular intervals. If it is constantly more than 140/90 at 2 readings then you can start medicine. But since yours is normally good do dieting consulting your nutritionist and exercise and you can control your BP, sugar and lipid level with this.. But get check your heart once. ECG, echocardiography
and treadmill test are required to rule out any problem.
Hope I answered your question. Feel free to ask me if you have any further queries. Wish you good health. Take care.
