Re: Weight & HBP
Losing weight is only one item in fighting high blood pressure. This assumes you are overweight.
Restricting salt (sodium) in your diet, including those foods high in salt (regular canned soups, pickles, etc.).
Regular exercise cleared with your doctor is also important.
If all the above fail to get your resting BP under 140/90, or if you have heart disease 135/85, then it's time for medication. There are 3 categories of drugs to reduce HBP and many choices under each one.
Since you are using equipment at the EMS, assuming you are resting for several minutes before you take it the first time, I assume the equipment is reliable.
The best specialist to treat HBP is a cardiologist. If this doctor does not satisfy your needs, find a cardiologist.
