In a new statement from the American Heart Association, researchers suggest that losing weight can be crucial to controlling blood pressure.
But when diet and exercise fail to help, medications and surgery are appropriate treatments.
High blood pressure, or hypertension, can lead to kidney problems, heart injury and stroke.
But only a fraction of eligible patients is prescribed weight-loss medicine or referred for metabolic surgery.
Even though treatments might help prevent serious complications, he said, they often aren’t considered until after someone has suffered organ damage.
In the statement, the team says when combined with lifestyle changes, anti-obesity medicines and surgical procedures can be effective long-term solutions for weight loss and blood pressure control in select individuals who are overweight or obese.
Weight loss through a healthy diet and increased physical activity is the cornerstone of treatment for high blood pressure that’s related to being overweight.
National guidelines recommend a heart-healthy diet to help manage weight and control blood pressure. The Mediterranean diet and Dietary Approaches to Stop Hypertension (DASH) are well-established options.
Both emphasize eating more fruits, vegetables, legumes, nuts and seeds; moderate amounts of fish, seafood, poultry and dairy; and low quantities of sweets and red and processed meats.
The statement also looked at intermittent fasting, an approach that alters the timing of eating and fasting during the day or week.
It produced modest reductions in blood pressure in a few studies involving people with metabolic syndrome, a group of conditions that can lead to heart disease.
However, analyses of several studies found intermittent fasting had a weak impact on blood pressure and was no more effective than other diets in reducing weight.
Maintaining weight loss in the long term is challenging. So when diet and exercise aren’t working, health professionals should consider prescription medications for people who have a weight-related health issue such as high blood pressure.
A class of medications called GLP-1 receptor agonists has been shown to help with sustained weight loss and significantly reducing blood pressure, according to the statement.
GLP-1 agonists, such as liraglutide and semaglutide, are synthetic hormones self-injected daily or weekly that reduce appetite and help people feel full.
Both medications were initially prescribed to treat Type 2 diabetes because they lower blood sugar by stimulating the release of insulin.
The Food and Drug Administration recently approved both for weight management and weight loss in people classified as overweight or obese.
The statement also includes a research review on metabolic surgery, also called bariatric surgery or gastric bypass surgery.
It can aid weight loss in people with severe obesity, defined as people who have a BMI of 40 or higher, or if they have a BMI of 35 or higher along with an obesity-related health condition such as hypertension.
High blood pressure resolves in 63% of people who have metabolic surgery, the report said, and several studies show less use of blood pressure-lowering medicines after surgery.
If you care about blood pressure, please read studies about this common nutrient may help prevent high blood pressure and findings of scientists discover new major cause of high blood pressure.
For more information about blood pressure health, please see recent studies about the key to treating high blood pressure and results showing that this eating style may help lower blood pressure, improve weight loss.
The study is published in Hypertension. One author of the statement is Dr. Michael E. Hall.
