High Blood Pressure Dizziness Fatigue

Low Blood Pressure As A Cause Of Dizziness

Dizziness, lightheadedness, and the feeling of passing out is a common complaint in people who have low blood pressure. When the blood pressure is too low, not enough oxygen-rich blood is delivered to the brain, and its function can be affected. If the brains blood supply is decreased too much, the person may pass out . Symptoms may worsen when changing position from lying down or sitting to standing up.

In addition to feeling dizzy, associated symptoms may include:

In individuals who are dehydrated or anemic, blood pressure readings may be normal when they are lying flat however, the lack of fluid is unmasked when they stand up quickly. The lack of blood to the brain may cause dizziness and lightheadedness. This feeling may pass in a few seconds as the body adapts. However, if dehydration or medications prevent the body from reacting by constricting blood vessels and increasing the heart rate, the dizziness may persist to the point at which the patient passes out .

Some diseases are associated with an inability to compensate for changes in body position . Normally when a person stands, blood vessels contract to increase blood pressure slightly, and the heart rate also increases slightly, to pump blood uphill to the brain against gravity. In autonomic dysfunction, a person may become dizzy when they move from a lying position to sitting or standing up. Examples of these diseases with this syndrome include diabetes, Addisons disease, or Parkinsons disease.

What Are The Signs Of Hypoglycemia

An individual may frequently wake up in the middle of the night as a result of nighttime hypoglycemia. In other instances, though, people may know if they experienced hypoglycemia during their sleep if they notice the following symptoms:

• Waking up with a headache
• Waking up in a sweat
• Getting unusual feelings of tiredness throughout the day
• Experiencing anxiety or heart palpitations
• Feeling confused, dizzy or weak

Cardionomic Circuit Dysfunction And Blood Pressure Symptoms

The first stage of Cardionomic Circuit Dysfunction has to do with the adrenal component and cortisol output. This is where you can start to notice high blood pressure symptoms, such as heart pounding, dizziness, and breathlessness.

After cortisol is increased, the sympathoadrenal hormone system of the ANS gets activated. This is the system that regulates adrenaline and norepinephrine. When these hormones are out of balance, more problematic cardiovascular symptoms appear, such as subclinical POTS .

If the dysfunction progresses further, it can damage the cardiac nodes, which regulate the heartbeat. This can lead to more specific blood pressure symptoms, such as postural hypotension, where you get a sudden drop in blood pressure upon standing up. You can also get atrial fibrillation and idiopathic supraventricular tachycardia.

And as the Cardionomic Circuit dysregulates more, the severity and frequency of such symptoms increase, as well as damage to the heart and blood vessels. You can also see full-blown POTS, panic attacks, and severe insomnia. Its possible to end up bedridden with a lot of cardiac damage.

Dizziness Fatigue High Blood Pressure And Nausea Or Vomiting

• Medical Author: Melissa Conrad Stöppler, MD

Reviewed on 12/1/2020

Dizziness and fatigue are common symptoms that can accompany many conditions and can be related to fluid lost through vomiting. High blood pressure often occurs without a known cause. Nausea and vomiting can occur with infections or conditions like food poisoning. If you are experiencing troubling symptoms that do not improve, contact your healthcare provider.

While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:

Your Reading Is Above 140/90

Blood pressure readings consist of two numbers. The top number is your systolic blood pressure and the bottom one is your diastolic blood pressure. Generally, a normal blood pressure reading was considered to be more than 120 over 80 and less than 140 over 90. However, in 2017, major heart health organisations around the globe unanimously decided to lower the blood pressure levels for the diagnosis of hypertension from the older threshold of 140/90 mm Hg and 150/80 mm Hg to 130/80 mm Hg and higher for all adults. Based on this new criteria, if your numbers are over 130/80 mm Hg then you should consult a doctor immediately or find ways to lower your blood pressure.

It is essential to keep tabs on your blood pressure, especially when you lead an unhealthy life or have a family history of hypertension. You can easily purchase a blood pressure monitor from your local pharmacy and drugstore to keep a check on your blood pressure. The readings are very accurate and similar to what you would get in a hospital.

Your blood pressure keeps changing constantly to adjust to your bodys activity level, hydration, sleep, food intake, and other factors. In order to get an accurate reading, you may need to take several readings of your blood pressure over time.

Pick a time when you are calm and well-hydrated, and repeat the test weekly or monthly under the same conditions. Write down the dates and readings so that you can take them with you on your next doctors visit.

Complications Of Type 2 Diabetes

Itâs important to get your blood sugar under control to avoid these serious conditions:

• Hypoglycemia. If your blood sugar falls below 70 milligrams per deciliter , it can lead to accidents, coma, and death.
• Hyperglycemia. Blood sugar that goes above 180 to 200 mg/dL can give you heart, nerve, kidney, and vision problems. Over the long term, it also can cause coma and death.

Over time, people with type 2 diabetes may have other health problems:

• Diabetic ketoacidosis. When you donât have enough insulin in your system, your blood sugar rises, and your body breaks down fat for energy. Toxic acids called ketones build up and spill into your urine. It can cause coma and death if you donât treat it.
• Heartand blood vessel diseases. People with diabetes are more likely to have conditions like high blood pressure and high cholesterol, which play a role in heart disease. Also, high blood sugar can damage your blood vessels and the nerves that control your heart.
• High blood pressure. Diabetes doubles your risk of high blood pressure, which makes you more likely to have heart disease or stroke.
• Nerve damage. This can cause tingling and numbness, most often in your feet and legs. But it can also affect your digestive system, urinary tract, blood vessels, and heart.
• Eyedamage. Diabetes can cause:
• Glaucoma, a buildup of pressure in your eyes
• Cataracts, a cloudiness of your lens
• Retinopathy, which is damage to the blood vessels in your eyes

Common Cause Of Dizziness May Spell Heart Trouble

Blood Pressure That Falls When You Stand May Be a Clue to Coming Heart Failure

March 19, 2012 âBlood pressure that drops when a person stands up may signal a higher risk for heart failure, a new study shows.

If further research supports the studyâs findings, a simple test that measures blood pressure change as a person gets to their feet may one day help doctors spot heart failure early, when it is most manageable.

The study followed more than 12,000 middle-aged adults for nearly two decades.

At the start of the study, researchers measured blood pressure while people were lying down and then several times over a two-minute period after they stood.

âIf the top number, the systolic number, fell by 20 or more points, or the bottom number, the diastolic blood pressure, fell by 10 or more points, then it was defined as orthostatic hypotension,â says Christine D. Jones, MD, an internist and resident in preventive medicine at the University of North Carolina at Chapel Hill.

In orthostatic hypotension, the blood pressure drops when the body is in an upright standing position, as compared to a reclining position. Sometimes the sudden dip causes a brief dizzy spell or head rush. In severe cases it may cause a person to faint.

âSometimes people can have it and not feel a thing,â Jones says.

What Do The Diastolic And Systolic Numbers Mean

How is blood pressure measured?

Blood pressure is measured with a blood pressure cuff and recorded as two numbers, for example, 120/80 mm Hg . Blood pressure measurements are usually taken at the upper arm over the brachial artery.

• The top, the larger number is called the systolic pressure. This measures the pressure generated when the heart contracts . It reflects the pressure of the blood against arterial walls.
• At the bottom, the smaller number is called the diastolic pressure. This reflects the pressure in the arteries while the heart is filling and resting between heartbeats.

Exercise Food And Alcohol

For people with type 1 diabetes, maintaining the correct blood glucose level involves balancing how much insulin you inject, the amount of food you eat, and how much energy you burn during exercise.

Hypoglycaemia may occur if youve taken your dose of insulin as usual, but your carbohydrate intake is lower than normal or has been used up more quickly. This may happen if you delay or miss a meal or snack, dont eat enough carbohydrate, or exercise more than usual.

People with diabetes whove drunk too much alcohol, or drank alcohol on an empty stomach, can also get hypoglycaemia.

However, its not always possible to identify why a particular episode of hypoglycaemia has occurred, and sometimes it happens for no obvious reason.

Other Causes For Fatigue With High Blood Pressure

Although fatigue can be a symptom of high blood pressure, a lack of sleep may actually be a contributing factor, too.

Sleeping 5 hours or less per night may raise your risk for developing high blood pressure. And if you already have high blood pressure, lack of sleep could be making it worse.

In addition, obstructive sleep apnea is a known risk factor for hypertension, especially in older age groups.

Some prescription medications used to treat high blood pressure can also cause fatigue.

Another cause of fatigue could be due to pulmonary artery hypertension. This is when you have high blood pressure in the vessels that carry blood between your heart and lungs. Along with fatigue, it can cause chest pain, shortness of breath, and lightheadedness.

There are usually no symptoms or warning signs that you have hypertension. Thats why its so important to monitor your blood pressure.

Its especially important to see your doctor if youre experiencing:

• fatigue

• stress management
• drinking alcohol in moderation

Your doctor will also consider your age, coexisting conditions, and any other medications you take when treating your blood pressure. If necessary, your doctor may prescribe hypertension medications. These include:

Some of these medications can cause you to feel tired.

Other treatments depend on the extent of damage to your heart, kidneys, and overall health.

What Is Considered High Blood Pressure

The American Heart Association and the American College of Cardiology have recommended guidelines to define normal and high blood pressure .

Guidelines to define normal and high blood pressure stages chart

Based on these new 2017 guidelines defining high blood pressure, as many as half of all Americans will have this disease . Uncontrolled high blood pressure is responsible for many cases of death and disability resulting from a heart attack, stroke, and kidney failure.

According to research studies, the risk of dying of a heart attack is directly linked to high blood pressure, particularly systolic hypertension. The higher your blood pressure, the higher the risk. Maintaining lifelong control of hypertension decreases the future risk of complications such as heart attack and stroke.

About 1% of people with high blood pressure do not seek medical care until the high blood pressure is very severe, a condition known as malignant hypertension or a hypertensive emergency.
