Many folks are becoming increasingly concerned about high diastolic blood pressure. Given that 116 million persons in the United States suffer from hypertension, according to CDC data, it is critical to comprehend the reasons for high diastolic blood pressure in 2025.
The pressure in your arteries during the period between heartbeats is measured by diastolic pressure, which is the lowest figure in a blood pressure reading. This handbook provides clear statistics, professional guidance, and doable measures to treat high diastolic blood pressure.
Many Don’t Understand High Diastolic Blood Pressure
Compared to systolic blood pressure, diastolic blood pressure is frequently disregarded. Even though a 2021 study published in the Journal of Hypertension found that 6% of adults under 50 suffer from isolated diastolic hypertension, many people are unaware of the causes of elevated diastolic blood pressure.
It’s difficult to determine whether your readings are problematic or how to treat them if you don’t know what causes high diastolic blood pressure.
Uncertainty results from this ignorance. Do your diastolic measurements seem excessively high? Do you need to worry? You could overlook early warning signals of a significant health problem and endanger your heart if you don’t know what causes high diastolic blood pressure.
The Risks of High Diastolic Blood Pressure
There are major health hazards if you don’t know what causes high diastolic blood pressure. According to CDC data, hypertension was a contributing factor in over 670,000 fatalities in the United States in 2020, primarily from heart disease and stroke.
In particular, a 2022 study published in the American Journal of Cardiology found that high diastolic pressure raises the risk of heart failure in persons under 60 by 25%. These risks are increased when the cause of high diastolic blood pressure is ignored.
The effects are not limited to the long term. According to a 2021 study published in the Journal of Clinical Hypertension, 20% of patients have everyday symptoms, including headaches and fatigue, as a result of high diastolic blood pressure.
Additionally, according to Psychosomatic Medicine, 15% of patients report feeling stressed out by their results. Being unaware of the causes of high diastolic blood pressure can drive you to put off taking action, which will harm your health.
Uncovering What Causes High Diastolic Blood Pressure
By 2025, the causes of elevated diastolic blood pressure are clearly defined by study. With the use of statistics and professional opinions, this part describes the primary causes, risk factors, and workable management strategies.
What Is Considered High Diastolic Blood Pressure?
Systolic (top) and diastolic (bottom) blood pressure readings are expressed in millimeters of mercury (mmHg). The definition of high diastolic blood pressure is as follows.
Normal Diastolic Pressure
- Range: Less than 80 mmHg
- Note: This is the healthy range for most adults, per the American Heart Association (AHA).
Elevated Diastolic Pressure
- Range: 80–89 mmHg
- Note: This is a warning sign and can progress to hypertension if not addressed.
High Diastolic Pressure (Hypertension)
- Range: 90 mmHg or higher
- Note: This defines what causes high diastolic blood pressure to be a concern, per AHA guidelines.
Main Causes of High Diastolic Blood Pressure
Several factors contribute to what causes high diastolic blood pressure. Here are the primary culprits.
Obesity
Being overweight causes artery stiffness, which raises diastolic pressure. According to a 2022 study published in the Journal of the American College of Cardiology, isolated diastolic hypertension was present in 40% of obese people. One of the main reasons for elevated diastolic blood pressure, particularly in those under 50, is obesity.
High Sodium Intake
An excess of sodium raises arterial pressure by causing fluid retention. According to the FDA, 45% of American adults in 2020 consumed more sodium than the recommended daily limit of 2,300 mg, which is often the cause of high diastolic blood pressure.
Stress
Prolonged stress causes the release of chemicals like cortisol, which raises blood pressure. According to a 2021 study published in Psychosomatic Medicine, stress is a major contributing factor to high diastolic blood pressure, as 30% of persons with high levels of stress had diastolic readings above 90 mmHg.
Lack of Physical Activity
Inactivity raises blood pressure and impairs circulation. Lack of exercise is linked to high diastolic blood pressure, as evidenced by a 2022 study published in the Journal of Hypertension, which found that 25% of sedentary individuals had high diastolic blood pressure.
Alcohol and Smoking
Blood vessels are harmed by both behaviors. According to the American Journal of Hypertension, 15% of smokers and 20% of heavy drinkers had high diastolic blood pressure in 2021, demonstrating how these behaviors contribute to the development of high diastolic blood pressure.
Secondary Causes of High Diastolic Blood Pressure
Sometimes, underlying conditions play a role in what causes high diastolic blood pressure.
Kidney Disease
Blood pressure is controlled by the kidneys. 10% of patients with chronic renal disease had isolated diastolic hypertension, according to a 2023 study published in the Journal of Nephrology, which suggests that kidney problems are the cause of high diastolic blood pressure.
Thyroid Disorders
Thyroid overactivity raises blood pressure. According to the Journal of Endocrinology, 8% of patients with hyperthyroidism had high diastolic blood pressure in 2022, indicating that thyroid problems are a contributing factor to high diastolic blood pressure.
Sleep Apnea
Blood pressure is elevated at night due to sleep apnea. According to a 2021 study published in the American Journal of Respiratory and Critical Care Medicine, elevated diastolic blood pressure is a contributing factor in 15% of sleep apnea patients.
Addressing High Diastolic Blood Pressure
A 2023 case study of a 45-year-old man shows how to tackle what causes high diastolic blood pressure.
- Profile: Diastolic blood pressure 92 mmHg, BMI 32, office worker, high sodium diet.
- Challenges:
- Ate 3,500 mg of sodium daily from processed foods.
- Sedentary lifestyle with less than 30 minutes of weekly exercise.
- Interventions:
- Reduced sodium to 2,000 mg/day by cooking fresh meals.
- Started 30-minute daily walks.
- Monitored blood pressure weekly at home.
- Results: Diastolic pressure dropped to 82 mmHg in 3 months, aligning with normal levels.
- Key Insight: Lifestyle changes addressed what causes high diastolic blood pressure, improving his health.
How to Manage High Diastolic Blood Pressure
Here are research-backed steps to manage what causes high diastolic blood pressure.
Reduce Sodium Intake
Don’t exceed 2,300 mg of salt per day. This addressed the cause of elevated diastolic blood pressure, lowering it by 5 mmHg in 60% of individuals, according to a 2021 study published in the American Journal of Clinical Nutrition.
Increase Physical Activity
Every week, try to get in 150 minutes of moderate activity. Regular exercise lowered diastolic blood pressure by 4 mmHg in 70% of participants, according to a 2022 study published in the Journal of the American Heart Association. This helps control the factors that lead to high diastolic blood pressure.
Manage Stress
Engage in deep breathing exercises and other relaxing methods. According to a 2023 study published in Psychosomatic Medicine, 50% of adults who meditated for 10 minutes a day saw a 3 mmHg drop in diastolic blood pressure, addressing the root cause of elevated diastolic blood pressure.
Limit Alcohol and Quit Smoking
Reduce your alcohol intake and give up smoking. Addressing the cause of high diastolic blood pressure, a 2022 study published in the Journal of Hypertension revealed that 80% of persons who stopped smoking experienced a 5 mmHg drop in diastolic blood pressure.
Professional Perspective: “Lifestyle changes can have a significant impact,” says Johns Hopkins cardiologist Dr. Mark Evans. “The first step to controlling high diastolic blood pressure is understanding what causes it.”
Challenges in Managing High Diastolic Blood Pressure
Not everyone can easily address what causes high diastolic blood pressure due to various barriers.
