What Can Happen If You Have High Blood Pressure

Summary And Future Directions

What causes high blood pressure?

We have attempted to summarize and highlight key elements of our recent thinking on the role of the sympathetic nervous system in long-term blood pressure regulation in humans. Our goal has been to use the marked inter-individual variability in MSNA seen in humans to begin to explore this topic. In normotensive young men MSNA is proportional to total peripheral resistance but the effects of this relationship on blood pressure are limited by a reciprocal relationship between MSNA and cardiac output and the fact that adrenergic sensitivity is blunted in subjects with high levels of MSNA. In young women these relationships are absent and there is some evidence that 2-adrenergic receptor mediated vasodilation limits the relationship between sympathetic activity and vascular resistance.

When we consider our findings and those of others in the context of emerging demographic trends for conditions like obesity, sleep apnea, physical inactivity and perhaps social stress we propose that an era of sympathetically driven hypertension exacerbated by the factors discussed above is here.

Get To Know Your Numbers

Because there arent any symptoms, its important to have your blood pressure checked regularly. Get to know the numbers and when to get help from your doctor.

Your blood pressure will have two numbers:

  • Systolic is the upper number, measuring when your heart is forcing blood through your vessels.
  • Diastolic is the lower number, measuring pressure between heart beats.

For example, 120/80 indicates a systolic blood pressure of 120 and a diastolic blood pressure of 80 mm/Hg.

Maintain A Healthy Weight

Being overweight is a risk factor for having high blood pressure, and your risk increases further if you are obese.

There are two ways to check if you are overweight:

  • Body Mass Index – This is your weight in kilograms divided by your height in metres squared. In the UK, people with a BMI of between 25 to 30 are overweight, and those with an index above 30 are classed as obese. People with a BMI of 40 or more are morbidly obese.
  • Waist size – Using a measuring tape place the tape round your waist between the bottom of your ribs and the top of your hip bone. The table below indicates how much your health might be at risk, your ethnicity should also be taken into account.
Sex
Over 80 cm

The best way to tackle obesity is by reducing the amount of calories that you eat, and taking regular exercise. Your GP can provide you with further information and advice on how you can do this.

Should I Be Concerned About Having High Blood Pressure And A Low Pulse

If youre taking blood pressure medication and have slightly high blood pressure and a low pulse, this generally isnt anything to be concerned about.

But if youre not taking any medication, its best to work with a doctor to figure out whats going on. This is especially true if you have symptoms of a low pulse, such as dizziness or shortness of breath.

The typical range of 60 to 100 beats per minute is both the average pulse measurement as well as the rate at which most peoples heart needs to beat to pump enough blood through their body.

Some people may simply have a lower pulse. Examples include athletes or those in very good shape. Theyve conditioned their heart muscle to be stronger. As a result, their heart pumps more effectively, meaning it doesnt need to beat as often. Learn more about why athletes have lower pulses.

Exercising can also temporarily raise your blood pressure. So, if you exercise regularly, you may have a naturally low pulse and higher blood pressure right after you work out.

Causes Of Sudden High Blood Pressure

According to the Centers for Disease Control and Prevention, one of out every three American adults suffers from diagnosed high blood pressure with only one half keeping their pressure under control. Sudden high blood pressure usually occurs to a small percentage of people with high blood pressure. This can include young adults, including a high number of African-American men, and those experiencing:

  • Collagen vascular disorders
  • Pregnancy-induced high blood pressure

Sudden high blood pressure can also be brought on by daily activities and practices.

  • Medication use such as over-the-counter pain relievers, a combination of various medications, and abuse of cocaine and marijuana can spike blood pressure levels.
  • Smoking can cause a sudden increase in blood pressure as the chemicals, including nicotine, damage the linings of our blood vessels.
  • Diet habits are critical to maintaining normal blood pressure levels as the bad fat and sodium found in many foods increase the blood solute content. It also can build up and block the blood vessels, leading to major heart trouble such as a stroke.
  • Stress is part of our everyday life and becoming anxious about your worries can increase risk for spikes in blood pressure twofold.
  • Medical conditions like kidney disease, spinal injuries, adrenal gland tumors, thyroid issues, and scleroderma can raise blood pressure rapidly.

A note from Cleveland Clinic

If you dont treat high blood pressure, it can put you at risk for developing serious illnesses later in life such as heart attack, kidney failure and stroke. But if you follow your providers instructions, you can control your blood pressure. Be sure to take any medicines your provider ordered as instructed. Keep taking them even if your blood pressure numbers begin to fall into the normal range.

How High Is Too High For Blood Pressure? Cardiologist Explains

If youre new to performing your own blood pressure readings, it can be helpful to understand what exactly your blood pressure reading is telling you. Your reading will be comprised of two numbers. The American Heart Association explains that the top number represents your systolic pressure or the pressure when your heart beats. The bottom number represents your diastolic pressure which is the pressure when your heart is in between beats.

For the average adult, a normal blood pressure reading is below 120 over 80 . If you have higher than normal blood pressure, it can range anywhere from elevated blood pressure to hypertensive crisis. According to Healthline, a person with elevated pressure may just need to adapt a to get their pressure to a healthy range, while hypertensive crisis warrants a trip to the emergency room. Hypertension is the medical term for high blood pressure and there are various degrees of severity which will impact what type of treatment plan your doctor prescribes.

What Diet Helps Control High Blood Pressure

  • Eat foods that are lower in fat, salt and calories, such as skim or 1% milk, fresh vegetables and fruits, and whole-grain rice and pasta.
  • Use flavorings, spices and herbs to make foods tasty without using salt. The optimal recommendation for salt in your diet is to have less than 1,500 milligrams of sodium a day. Don’t forget that most restaurant foods and many processed and frozen foods contain high levels of salt. Use herbs and spices that do not contain salt in recipes to flavor your food. Dont add salt at the table.
  • Avoid or cut down on foods high in fat or salt, such as butter and margarine, regular salad dressings, fatty meats, whole milk dairy products, fried foods, processed foods or fast foods and salted snacks.
  • Ask your provider if you should increase potassium in your diet. Discuss the Dietary Approaches to Stop Hypertension diet with your provider. The DASH diet emphasizes adding fruits, vegetables and whole grains to your diet while reducing the amount of sodium. Since its rich in fruits and vegetables, which are naturally lower in sodium than many other foods, the DASH diet makes it easier to eat less salt and sodium.

Learning To Cope With Stress Can Help

Stress and hypertension have often been linked, but researchers are still looking into a direct relationship between the two. Still, the best advice to hypertensive patients: Try to relax.

When you are stressed, your body sends stress hormones adrenaline and cortisol into the bloodstream. These hormones create a temporary spike in blood pressure, causing your heart to beat faster and blood vessels to narrow. When the stressful situation is over, blood pressure goes back to its normal level.

Chronic stress, however, may cause your body to stay in this highly-charged state longer than natural.

While stress itself may or may not affect blood pressure, how you cope with stress does. For instance, overeating, smoking and drinking alcohol in response to stressful situations are direct causes of sustained high blood pressure. On the flip side, healthier coping mechanisms like exercising, practicing yoga and meditating can all help lower blood pressure.
