High blood pressure and type 2 diabetes are two of the most common long-term health problems in the world today. Many people live with one of these conditions, often managing them with medication and lifestyle changes.
However, new research shows that when a person has both conditions at the same time, the health risks become much more serious.
A new study from Columbia University’s Mailman School of Public Health, published in the journal Diabetes Care, has found that people who have both high blood pressure and type 2 diabetes face a much higher risk of dying, especially from heart-related problems.
The findings highlight the importance of paying attention to both blood pressure and blood sugar, even before they reach dangerous levels.
High blood pressure, also called hypertension, happens when the force of blood pushing against the walls of the arteries is too high. Over time, this can damage blood vessels and increase the risk of heart disease, stroke, and kidney problems.
Type 2 diabetes is a condition in which the body cannot properly control blood sugar levels. High blood sugar can also damage blood vessels and organs.
When these two conditions occur together, their harmful effects can combine and become even stronger. According to the study, nearly half of adults in the United States already have high blood pressure, and about 15 percent have type 2 diabetes.
In addition, more than one-third of adults have prediabetes, which means their blood sugar levels are higher than normal but not yet high enough to be diagnosed as diabetes. Without changes in lifestyle, many of these people will develop diabetes in the future.
The researchers analyzed health data from almost 49,000 adults who took part in a national survey between 1999 and 2018. They divided the participants into groups based on whether they had no conditions, only high blood pressure, only diabetes, or both conditions.
Over time, the number of people living with both high blood pressure and diabetes increased significantly, doubling from 6 percent to 12 percent. People with both conditions were more likely to be older and to have lower income or education levels. They were also more commonly found in certain communities, including Black and Hispanic populations.
The study followed participants for about nine years to see how many people died and what caused their deaths. The results were clear and concerning.
About one-third of people who had both conditions died during the follow-up period. In comparison, 20 percent of people with diabetes alone and 22 percent of people with high blood pressure alone died. Among those who had neither condition, only 6 percent passed away.
Having both high blood pressure and diabetes was linked to a doubling of the risk of death from any cause. The risk of dying from heart disease was even higher, nearly three times greater than for people without these conditions. These patterns were seen across different groups of people, although women generally faced slightly higher risks than men.
The study also found that the danger begins earlier than many people might expect. Even people with prediabetes and slightly elevated blood pressure had up to a 19 percent higher risk of dying compared to those with normal levels. This shows that small changes in health can still have a meaningful impact over time.
When comparing groups more closely, people with both conditions had a 66 percent higher risk of death than those with only high blood pressure, and a 25 percent higher risk than those with only diabetes. The risk of dying from heart disease was especially high when both conditions were present.
These findings suggest that doctors and patients should pay close attention to both blood pressure and blood sugar levels. Managing just one condition is not enough if the other is also present or developing. Early action, including healthy eating, regular physical activity, and proper use of medications, can help reduce these risks.
The researchers also emphasized the need for better public health strategies. This includes improving access to healthcare, supporting people in managing their conditions, and creating programs that address multiple health risks at the same time.
As the population continues to age and chronic diseases become more common, the importance of prevention becomes even greater. By understanding the risks and taking action early, people can improve their chances of living longer and healthier lives.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and natural coconut sugar could help reduce blood pressure and artery stiffness.
