高血圧の症状と高血圧の原因 High Blood Pressure Symptoms and Hypertension Causes.

 

Have you ever wondered why your blood pressure is higher in the afternoon and evening and low at night? Untreated, significant fluctuations can increase your risk of developing serious health problems and damaging your cardiovascular system.

We make it easy for you to participate in a clinical trial for High blood pressure, and get access to the latest treatments not yet widely available - and be a part of finding a cure.

Circadian rhythms. Your circadian rhythm is connected to the master clock in your brain which regulates your body function throughout the day. In contrast, when the sun is up, your master clock makes sure you have enough energy to stay alert and go about your day. Physical activity. Being active and exercising regularly helps reduce your risk of developing high blood pressure in the long term.

For people with diagnosed hypertension , exercise has been found to cause a blood pressure dip called postc-exercise hypotension PEH. You might notice your blood pressure reading change slightly during or after exercise. This is normal, but a significant change could suggest you have hypertensive response to exercise HRE. HRE is thought to be an early warning sign for developing hypertension. Nervousness and stress. When this happens, your heart rate rises and your blood vessels narrow vasoconstriction , raising your blood pressure temporarily.

This is a normal response from your body. White-coat syndrome. Have you ever wondered why your blood pressure reading is normal at home and rises at the doctors? This is white-coat syndrome , and it occurs when you feel stressed about visiting your doctor or being in a clinical environment. Eating and drinking.

Consuming food and drink affects your blood pressure, with some foods having more of an influence than others. Some common medications like non-steroidal anti-inflammatory drugs NSAIDs and decongestants can also elevate blood pressure.

But how does this affect blood pressure? Their blood pressure started to drop during the day and rise at night when they were awake. However, sleep quality was found to be lower for night shift workers which can cause blood pressure complications. These effects are risk factors for high blood pressure.

This might suggest that some people adapt more easily than others, and sticking to a reversed schedule and avoiding rotating shifts if you can could make it easier for your body to adjust.

You might be asked to monitor your blood pressure with a machine you can use at home. But since blood pressure fluctuates throughout the day, is there a best time to take a reading?

Follow these recommendations to get an accurate blood pressure reading :. Measure your blood pressure at the same time each day. A good first step is to check your blood pressure at the same time every day to help even out fluctuations. You should also try to arrange appointments with your doctor at the same time of day.

Sit in the best position. Sit upright with your feet flat on the floor and your arm supported at the level of your heart rest it on a table or pillow. Use the same arm each time you check your blood pressure. Resist the urge to talk or do other activities while your blood pressure is being taken. Take a reading twice a day. Some experts suggest checking blood pressure twice a day: when you first get up and in the evening after work.

This would be the opposite if you work night shifts. Taking a blood pressure reading twice a day will also help you detect any abnormal fluctuations. Wait 30 minutes after eating, drinking, smoking, or exercising. Leaving some time before you take a blood pressure reading after eating, drinking including alcohol and caffeine , smoking or exercising can allow your blood pressure to stabilize. Keep a record of your readings. Keeping a record of your blood pressure readings is a good way to get an accurate, average measurement and highlight any unusual patterns.

High blood pressure is not diagnosed after one high reading; your doctor will assess your average blood pressure, so being able to show them a blood pressure log will be helpful. Here are some additional tips that can help you get an accurate reading:. Place the cuff on your bare skin, not over your clothes.

Make sure your bladder is empty before checking your blood pressure. You might expect to see a dip at night and pressure gradually rising through the afternoon and evening according to your circadian rhythm. Severe or unusual fluctuations suggest your daily blood pressure pattern is abnormal. Too much fluctuation. If your blood pressure fluctuates significantly or at unexpected times, you might have high blood pressure. Labile hypertension is the medical term for blood pressure that rises suddenly and significantly, causing serious complications.

If your doctor believes you might have labile hypertension, they might ask you to monitor your blood pressure at home and take multiple readings at different times of the day. Blood pressure not falling at night. Ongoing nocturnal hypertension can cause cardiovascular problems, cognitive dysfunction, chronic kidney disease, falls, stroke, and organ damage, so many doctors now recommend taking certain blood pressure medications before going to bed.

Nocturnal hypertension is difficult to spot as blood pressure readings are typically taken during the day, and it can only be detected when you wear a blood pressure monitor at night. Snoring or morning fatigue are typically used to diagnose OSA, so it is often missed in people who sleep alone.

Although the link is still unclear, non-dipping nighttime blood pressure might suggest you have another sleep disorder, such as insomnia. Treating sleep disorders can help reduce the risk of heart problems and restore a normal dipping pattern. Your doctor might recommend exercising in the evening if you have hypertension or nocturnal hypertension.

Blood pressure dropping too low at night. If your blood pressure is too low when you wake up, you may become dizzy or faint when you try to get out of bed.

This is called orthostatic hypotension. Your blood is circulating as normal when you lie down but is unable to reach your brain when you stand up. It can increase your risk of falls and injury, especially if you are older. It can also increase your risk of stroke. These problems can be treated by adjusting your blood pressure medication or the time you take it.

Blood pressure fluctuations can make it challenging to take an accurate, meaningful reading, and severe fluctuations can increase your risk of health problems. You might be wondering if there's anything you can do to reduce this variability and stabilize your blood pressure. Your first priority should be to continue taking your medication as directed. Your doctor can make specific suggestions depending on your individual symptoms and how your blood pressure fluctuates.

This might include taking your blood pressure medication except diuretics at bedtime to reduce nighttime blood pressure, taking them in the morning if your blood pressure is dropping too low, or exercising at a different time of day. If you have resistant hypertension, there are surgical treatments available as a last-resort option. Blood pressure naturally drops at night, increases through the day, peaks at midday, and stays high through the afternoon before decreasing in the evening.

This is affected by the circadian rhythm among other factors, like exercise, food and drink, and stress. Shift workers might see a reversed pattern. People with hypertension often experience wider fluctuations, although these generally stabilize with treatment. Ambulatory monitoring wearing a blood pressure monitor for 24 hours is the only way to assess your daily blood pressure fluctuations. To get an accurate reading, take multiple measurements at the same time each day and wait 30 minutes after exercising, eating, drinking, or smoking.

As early as , the Metropolitan Life Insurance Company published a chart showing that as blood pressure levels rose, life expectancy fell. Conversely, the lower the levels, the longer the life. And who doesn't want a long, healthy life?

For decades hypertension, or high blood pressure, has been recognized as one of the Big Three risk factors for cardiovascular disease, along with elevated cholesterol levels and cigarette smoking. With what we know today, though, diabetes should be added to the list of major risk factors-one of the Big Four. Of course, genes and family medical history play a huge role, but those genetic traits simply predispose you to problems down the road. Eliminate the risk factors that convert the potential to the real, and the question of family history becomes virtually moot.

When I began preaching that mantra twenty years ago, many doctors said I was exaggerating, oversimplifying. Back in , actuarial tables that predicted life span indicated death within ten years for a man of thirty-five who had a family history of cardiovascular disease, had a long list of risk factors, and had suffered a heart attack and undergone bypass surgery.

This means that I should have been dead by age forty-three, sooner rather than later. But I guess I fooled them! Today the vast majority of doctors and medical authorities agree that cardiovascular diseases, and deaths from heart attacks and strokes, are largely preventable. You simply have to make the decision, as I did, to eliminate the risk factors.

As virtually any doctor will tell you, the risk posed by hypertension can be completely eliminated. Here's a happy thought, something to inspire your commitment to good health in general and to blood pressure control in particular. Several-not just one or two-trials have demonstrated without doubt that reductions of systolic blood pressure by as little as one to three points will decrease your relative risk of stroke by as much as 20 to 30 percent.

That's one heck of a return on your investment! The following numbers speak for themselves, and I present them without commentary or fearmongering. In the white population, Nineteen percent of Hispanics and These rates of high blood pressure contribute significantly to the annual occurrences of 7.

But there's a lot we can do to make sure we're not counted in those statistics. Hypertension Risk Factors and What We Can Do about Them Family history certainly plays a large role in determining whether you will develop hypertension, but I prefer to think of it merely as a warning. If the gate goes down and the lights go on at a railway crossing, you've got a pretty good idea that a train is on its way.

A wise person would never put himself or herself in harm's way by trying to race a car across the tracks. We don't tempt fate by indulging in reckless behavior. Just because your grandfather had hypertension and died from a stroke doesn't mean that you can't take steps to avoid repeating that history. Race definitely comes into play. High blood pressure is far more common in blacks than in any other racial group, and it hits at an earlier age.

But we know that African Americans are far more sodium sensitive than whites are and at the same time they have diets that are high in sodium, doubling the problem. The solution seems pretty obvious. Similarly, obesity and diabetes are more prevalent among blacks. Rather than wringing his or her hands in despair, the wise black individual will take appropriate action. High blood pressure is more common in young and middle-aged men than in women of similar ages.

In those age sixty and older, however, it is more common in women. Blood pressure testing, a simple and painless way to know if you're at risk, is available to everyone, regardless of sex. You can certainly take control of the other risk factors involved in the gradual progression of elevated blood pressure and subsequent hypertension.

Obesity plays a big part. The greater your body mass, the more blood is needed to supply oxygen and nutrients to your muscles and other tissues.

Obesity increases the number and length of blood vessels, thereby increasing the resistance of blood that has to travel longer distances through those vessels. Increased resistance results in higher blood pressure. Fat cells themselves manufacture substances that adversely affect both the heart and the blood vessels.

Sedentary behavior boosts your risk by deconditioning the heart muscle just as much as it does other muscles in the body. Couch potatoes tend to have higher heart rates because their heart muscles aren't as efficient and have to work harder to pump blood. Moreover, physical activity is a vasodilator; that is to say, exercise of any sort dilates blood vessels. Combining inactivity with being overweight multiplies the problem. Sodium and salt intake remain controversial as risk factors for hypertension.

While it's true that some individuals are particularly sensitive to sodium, whether from the salt shaker or from sodium-based ingredients in processed and fast foods, not everyone responds to sodium equally.

As we'll see, sodium is but one of many minerals, or electrolytes, that affect blood pressure. Increasing your intake of the others may be as important as, or more important than, decreasing your intake of sodium, other than for people who are proven to be sodium sensitive. Alcohol definitely affects blood pressure, but this is a gray zone.

Excessive alcohol consumption can raise blood pressure, whereas moderate drinking may actually help to keep it under control. Stress is another highly controversial subject in the medical research community, although doctors in clinical practice regularly see the effects of stress in their patients.

Stress boosts the production of harmful substances, increases the heart rate and blood requirements, and can over time raise blood pressure and precipitate a heart attack or a stroke. Again, there are many effective, proven methods to help you cope with stress. Symptoms of High Blood Pressure For the most part, hypertension is indeed a silent killer with no symptoms to tip you off that something might be wrong.

An exception would be someone who experiences a dull headache, typically in the back of the head and usually in the morning.

Bear in mind that such headaches are the rare exception rather than the rule. Ordinary headaches, dizziness, and nosebleeds are not symptoms, at least in the early stages of blood pressure elevation.
