Scientists have long debated the effects of caffeine on blood pressure. But an analysis of 34 studies seems to have delivered a verdict. On average, consuming 200 to 300 mg caffeine (the amount found in one or two cups of coffee) raises systolic blood pressure by 8 mmHg and diastolic blood pressure by 6 mmHg. And the effects can last for up to three hours. (For reference, 8 ounces of drip coffee contain 100-125 mg of caffeine; the same amount of tea, 50 mg; an equal quantity of cola, about 40 mg.)
While you shouldn't shrug off the change, there's also no need to panic. "Obviously, nothing happened overnight inside a woman's body or to her health with the release of the guidelines," says Dr. Naomi Fisher, director of hypertension service and hypertension innovation at the Brigham and Women's Hospital Division of Endocrinology, Diabetes, and Hypertension, and associate professor of medicine at Harvard Medical School.
Providing at least 5 servings of vegetables and 4 servings of fruits daily, which help ensure that you eat plenty of foods that are full of stomach-filling volume yet are low in calories, enhancing weight-loss efforts. Losing excess weight is one of the most effective ways to lower blood pressure in the short term. Eating plenty of nutrient-rich fruits and vegetables also means you’ll be eating excellent sources of potassium, magnesium, and calcium. Many studies have found that foods rich in these minerals help blunt some of the toxic effects of sodium.
Dear Dr. Kernisan, you don’t know how thrilled I am to hear back from you!! There seems to be so little kindness these days that I so appreciate your caring response. I have had little success finding information about malignant hypertension. You mentioned following up was a lot of work, but it has been so consuming for me due to my fear, but also trying for a decent quality of life with as few side effects as possible, that my daughter says I need to find something else to do. (I have no other family left)…Besides a very stressful job, and caregiving for my mother who lived to be 97, I have always done volunteer work, so am really ready to get back to being productive…As far as my malignant spikes, I have asked every doctor and no one has an answer as to why it suddenly developed. That is one reason it is so scary. The nephrologist says he guesses it was from years of chronic stress. All the tests (kidney and carotid artery) were negative. I do a ton of research and am so glad to have found your site!! I found you through a link in a Washington Post article by Janice Neumann on August 17 “New Blood Pressure Guidelines Can Cause Problems for the Elderly”… I did not find a way to contact her. I have had no luck finding similar patients but need to learn social media skills. Thank you again so much!!!! I will be a faithful follower from now on!!! Best Regards, Kathy
Diabetics often have lower recommendations for blood pressure, the maximum normal value being seen as 130/80-85. However, it’s questionable whether it’s a good idea to medicate your blood pressure levels down to those values. Diabetics can probably stick to approximately the same upper limit as people with heart disease: 140/90 (according to new studies and expert comments, as well as the latest recommendations from the American Diabetes Association, ADA).
It's time to heed your partner's complaints and get that snoring checked out. Loud, incessant snores are a symptom of obstructive sleep apnea (OSA), a disorder characterized by brief yet potentially life-threatening interruptions in breathing during sleep. And many sleep apnea sufferers also have high levels of aldosterone, a hormone that can boost blood pressure, according to University of Alabama researchers. In fact, it's estimated that sleep apnea affects half of people with high blood pressure.
