Blood pressure My blood pressure has increased to 170/74

i don't know. if you feel your readings are true, visit your doctor or hospital promptly. don't delay.
i suspect you may not be having a proper compression fitting on the arm with the lower reading.
some **** stores here have a ' no charge ' machine at a bench, that lets you test your blood pressure. you might like to try that on both arms and record the numbers. many electronics retailers sell a wrist band [ about $20 ] that reads pressure and pulse.

Rena: Normal blood pressure is a reading below 120/80. Your bottom number is a little too high. Here is where to start: decrease salt in your diet. Try to decrease stress (like taking a stress management class). Increase your daily exercise. Herbs that may help lower blood pressure include basil, cinnamin, flaxseed, garlic, ginger, hawthorn, celery seed, French lavendar, and cat's claw (but NOT the real cat!) :) Take your blood pressure at different times of the day and keep a record. Uncontrolld high blood pressure can lead to stroke by damaging and weakening your brain's blood vessels, causing them to narrow, rupture or leak. High blood pressure can also cause blood clots to form in the arteries leading to your brain, blocking blood flow and potentially causing a stroke. I used to work in a dialysis clinic and there were always plenty of men that did not control their blood pressure for many years and eventually wore out their kidneys. If you consistently stay above the recommended numbers, go see your doctor.

nothing to eat unless you want to clog up the heart but dehydration or lack of regular water intake affects blood pressure
talk with a doctor as you need to fully understand "blood pressure" and what it means in the body
Low blood pressure readings are normal and it is the high pressure readings that are dangerous
Again talk with a doctor to be correctly informed and what your particular blood pressure readings should be

Check with GP

Go to see your GP

low blood pressure
dont muck about get to a medical professional for ECG
and advice

could mean medication like blood thinners

First age is not a factor.
60 mm Hg or less is generally considered low blood pressure
This is usually caused by congestive heart failure, and as far as increasing the pressure it would be a question for your Cardiologist.

perhaps the safest way to increase it to first talk to your Doctor.
