Can Low Blood Pressure Cause Nausea

Treatment For Low Blood Pressure Depends On The Cause

Low Blood Pressure or Hypotension, Causes, Signs and Symptoms, Diagnosis and Treatment.

If a cause can be found, a GP will be able to recommend treatment to ease your symptoms.

For example, they may suggest:

  • changing medicines or altering your dose, if this is the cause
  • wearing support stockings this can improve circulation and increase blood pressure

Medicine to increase blood pressure is rarely needed because simple lifestyle measures or treating the underlying cause is usually effective.

Why You Might Have Low Blood Pressure

Low blood pressure has many possible causes, from lifestyle choices, to medication or an underlying health condition.

In some cases, it may just be the result of being healthy and active or a tendency you’ve inherited from your parents.

Throughout the day, it’s normal for your blood pressure to vary depending on what you’re doing. Stress at work, the temperature outside and your diet could all affect your blood pressure reading.

This is why it’s important your blood pressure is checked under similar conditions each time to make sure results are consistent.

High Blood Pressure In Adults

Blood pressure is a measurement of the force exerted against the walls of your arteries as your heart pumps blood to your body. Hypertension is the term used to describe high blood pressure.

Untreated high blood pressure can lead to many medical problems. These include heart disease, stroke, kidney failure, eye problems, and other health issues.

Blood pressure readings are given as two numbers. The top number is called systolic blood pressure. The bottom number is called diastolic blood pressure. For example, 120 over 80 .

One or both of these numbers can be too high.

  • Normal blood pressure is when your blood pressure is lower than 120/80 mm Hg most of the time.
  • High blood pressure is when one or both of your blood pressure readings are higher than 130/80 mm Hg most of the time.
  • If the top blood pressure number is between 120 and 130 mm Hg, and the bottom blood pressure number is less than 80 mm Hg, it is called elevated blood pressure.

If you have heart or kidney problems, or you had a stroke, your doctor may want your blood pressure to be even lower than that of people who do not have these conditions.

Postprandial Hypotension And Blood Pressure

Some people are genetically predisposed to postprandial hypotension. In others, it comes on after a stroke, accident, or other trauma damages key nerves or blood pressure sensors. In most people, though, postprandial hypotension stems from aging-related changes that interfere with the body’s ability to respond quickly to sudden changes in blood pressure.

A major culprit is high blood pressure, which stiffens arteries, making it harder for them to narrow and relax as needed. Failure of blood pressure sensors in the arteries or stretch receptors in the stomach can lead to postprandial hypotension, as can diabetes, Parkinson’s disease, and other nerve-damaging conditions.

Low Blood Pressure: Signs, Symptoms, and Complications

If you have high blood pressure, you will have regular checkups with your provider.

Even if you have not been diagnosed with high blood pressure, it is important to have your blood pressure checked during your regular check-up, especially if someone in your family has or had high blood pressure.

Contact your provider right away if home monitoring shows that your blood pressure is still high.

What Do Blood Pressure Numbers Mean

Blood pressure is measured using two numbers:

The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats.

The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.

If the measurement reads 120 systolic and 80 diastolic, you would say, 120 over 80, or write, 120/80 mmHg.

Parents Of Children With Diabetes

If your child has diabetes and shows symptoms of hypoglycemia, it’s important to check their blood glucose level with a glucometer. If this is not possible, it is best to treat them as if they have hypoglycemia by giving them carbohydrates to prevent symptoms from getting worse.

Your child should have a safety plan in place for when they are not in your care, such as when they are at school, friends homes, or daycare. The plan should include whom they should talk to if they are not feeling well.

Talking to your child about their diabetes and the symptoms to be aware of helps keep them safe. When your child is aware that how theyre feeling is related to their blood sugar levels and diabetes management, they can learn to both self-identify and verbalize or signal to their parents when they need treatment.

What Is Low Blood Pressure

Hypotension, or low blood pressure, is when your blood pressure is much lower than expected. It can happen either as a condition on its own or as a symptom of a wide range of conditions. It may not cause symptoms, but when it does, it can require medical attention.

Hypotension has two definitions:

  • Absolute hypotension: Your resting blood pressure is below 90/60 mmHg .
  • Orthostatic hypotension: Your blood pressure drops within three minutes of you standing up from a sitting position. The drop must be 20 mmHg or more for your systolic pressure and 10 mmHg or more for your diastolic pressure. Another name for this is postural hypotension because it happens with changes in posture.

Measuring blood pressure involves two numbers, top and bottom, in mm/Hg.

  • Systolic : Your systolic pressure is the pressure on your arteries each time your heart beats. To find your systolic pressure, a healthcare provider* inflates a cuff that squeezes your arm. At the same time, they listen to your pulse at a point below the cuff. Your systolic pressure is when they cant hear your pulse anymore because the cuffs pressure is stronger than the pressure from your heart pumping.
  • Diastolic : That number is how much pressure your arteries are under between heartbeats. The provider will keep listening for your pulse to find your diastolic pressure while they deflate the cuff. Your diastolic pressure is the number where they can again hear your heartbeat as the cuff deflates.

What Can I Do For Myself

Does High Blood Pressure Cause Nausea or Dizziness?

There are other things you can do for yourself to help with your symptoms.

  • Wear supportive elastic stockings . They put extra pressure on your legs which helps to improve circulation and raise your blood pressure. For some people this can be enough, but speak to your GP first because they arent suitable for everyone.
  • Stand up slowly from sitting or lying down. You can try other simple movements to get the blood flowing before you stand up, such as straightening and bending your legs.
  • Avoid standing for long periods of time.
  • Drink enough water throughout the day, around 2 litres, so you dont get dehydrated.
  • Eat little and often throughout the day. This avoids low blood pressure after eating.

Why Am I Experiencing Lightheadedness And Nausea

It can be caused by something as simple as an ear infection, or it could be something more serious. Lets take a look at some of the causes:

1. Anemia

Anemia is a condition where there is not enough iron and red blood cells in the body to carry critically necessary oxygen and nutrients where they are needed.

Symptoms: Anemia symptoms include: feeling dizzy, fatigue, nausea, headache, pale skin, and feeling cold.

What to Do: If you suspect you may be anemic, see your doctor. You may need tests to look for a low red blood cell count including:

  • Complete blood count
  • Iron and ferritin levels

Make sure you are eating plenty of iron rich foods such as blackstrap molasses, lean red meats, spinach, and iron fortified cereal and bread.

2. Pregnancy

Two of the most common symptoms of pregnancy are nausea and feeling lightheaded. Nausea is caused by hormonal changes in the body and lightheadedness can be due to the rapid changes in blood and fluid volume to support you and your baby.

Symptoms: Symptoms of pregnancy include: nausea, missed period, tender and sore breasts, lightheadedness or feeling dizzy, bloated abdomen, feeling very tired, and others depending on how far along you are.

What to Do: If you do not have a diagnosed pregnancy, try a home pregnancy test and see your doctor to confirm. If you are diagnosed with pregnancy, try drinking extra fluids and nibble on crackers when you first wake up.

3. Lyme Disease

7. Motion Sickness

Cause: Expanded Blood Vessels

Sometimes your blood vessels widen. That means there’s more space for blood to spread out, which puts less pressure on the walls of those vessels. Some drugs, especially a type called vasodilators, can cause this. So can spinal injuries that damage certain nerves, serious bacterial infections, and allergic reactions. Hormone problems like Addison’s disease, which weakens the adrenal glands, can also do it.

Take Your Medicine As Usual

Insulin is a life-saving medication. Take your insulin as usual, even if you have been feeling very sick and vomiting. Ask your doctor, if necessary, how to adjust your insulin dose based on blood glucose test results.

If you are taking other diabetes-related medications to help manage your blood sugar levels, take these medications as you usually would, even in cases where you have been vomiting. Do not stop taking your medication even if you cannot eat.

If at any time you become doubtful about taking your medication or grow unsure about what the proper dose and time to take your medication should be, contact your healthcare team immediately.

How Is It Treated And Can It Be Cured

Treating hypotension usually starts with finding out why its happening. If that cause is treatable directly, hypotension will usually get better on its own. An example of this is hypotension that happens because of an injury and blood loss. Repairing that injury and replacing the lost blood will stop hypotension as long as the repair to the injury holds. If you take medications that affect your blood pressure, your healthcare provider may change your dosage or have you stop taking that medication entirely.

If the cause remains a mystery, its also possible to treat it directly. However, curing hypotension is only possible if theres an underlying cause thats curable.

When To See A Doctor

If you feel confused or notice fast, shallow breathing, a weak, rapid pulse, and cold, clammy skin, you may be in shock . Get to an emergency room right away. But lower blood pressure numbers, especially without other symptoms, aren’t usually a sign of a big problem. Talk to your doctor if you start to feel dizzy or lightheaded as well.

When To See Your Gp

You should see your GP if you have frequent symptoms of low blood pressure. Your GP can measure your blood pressure and help identify any underlying causes of the problem.

All adults should have their blood pressure checked at least every five years. If you haven’t had yours measured or don’t know what your reading is, ask your practice nurse or GP to check it.

Can Lack Of Sleep Cause Low Blood Pressure

What Causes Low Blood Pressure? Dr.Berg

Sleep provides time for the body to restore and recharge, playing a key role in nearly all aspects of physical health. For the cardiovascular system, insufficient or fragmented sleep can contribute to problems with blood pressure and heighten the risk of heart disease, heart attacks, diabetes, and stroke.

How Does Blood Pressure Work

During relaxation of the heart , the left ventricle of the heart fills with blood returning from the lungs. The left ventricle then contracts and pumps blood into the arteries . The blood pressure in the arteries during contraction of the ventricle is higher because blood is being actively ejected into the arteries. It is lower during relaxation of the ventricle when no blood is being ejected into the arteries. The pulse we feel when we place our fingers over an artery is caused by the contraction of the left ventricle and the ejection of blood.

Blood pressure is determined by two factors:

  • The amount of blood pumped by the left ventricle of the heart into the arteries, and
  • The resistance to the flow of blood caused by the walls of the arterioles .
  • Generally, blood pressure tends to be higher if more blood is pumped into the arteries or if the arterioles are narrow and/or stiff. Narrow and/or stiff arterioles, by resisting the flow of blood, increase blood pressure. Arterioles may become narrower when the muscles surrounding them contract. Arterioles may become stiff and narrow when older patients develop atherosclerosis.

    Blood pressure tends to be lower if less blood is being pumped into the arteries or if the arterioles are larger and more flexible and, therefore, have less resistance to the flow of blood.

    The heart rate increases and the forcefulness of the heart’s contractions increase, pumping more blood through the heart.

    What Medications/treatments Are Used

    Treating hypotension directly usually happens in one of three ways:

    • Increasing blood volume. This method, also known as fluid resuscitation, involves infusing fluids into your blood. Examples of this include intravenous fluids, plasma or blood transfusions.
    • Making blood vessels constrict. Just as there are medications that lower your blood pressure by relaxing blood vessels in your body, there are also medications that have the opposite effect.
    • Change how your body handles fluids. Your kidneys are responsible for maintaining the fluid balance in your body. Certain medications can make your kidneys keep fluid and salt in your body, which can help with low blood pressure.

    Complications/side effects of the treatment

    The complications of either treatment depend on the exact medication or treatment you receive. Your healthcare provider can best explain the possible complications or side effects. Thats because they can consider your specific circumstances, including other health conditions, medications you take and more.

    Low Blood Pressure And Headaches

    A normal blood pressure is considered less than 120/80 milligrams of mercury . The top number is called the systolic reading and the bottom number is the diastolic reading. They correspond to the different parts of the heart’s beating cycle.

    Hypotension occurs when blood pressure is low and causes symptoms. This varies by individual. For example, someone whose resting blood pressure is typically high may experience symptoms of low blood pressure at a higher level than another individual.

    While there is no specific cutoff for blood pressure to be called hypotension, a blood pressure below 90/60 mmHg in an otherwise healthy person may be considered low.

    Headaches can have a range of causes. Low blood pressure is just one of many possibilities.

    Sleep Deprivation And Blood Pressure


    There has been some link between getting less than six hours of sleep per night and increased blood pressure. It is generally thought that adequate sleep allows for the body to better regulate stress hormones and the nervous system. Scientists believe that without providing your body with the rest it needs, we are less able to regulate our stress and therefore increase our likelihood of high blood pressure. Aiming for a regular seven to eight hours of restful sleep each night may be both a prevention and treatment method for high blood pressure.

    How Is Low Blood Pressure Treated

    You will likely get treated for low blood pressure only if it is causing symptoms or if your blood pressure drops suddenly. Treatment depends on your symptoms, how severe they are, and the reasons for the low blood pressure.

    Your doctor may have you:

    • Get fluid through an intravenous line if you are very dehydrated.
    • Change or stop medicines that lower your blood pressure.
    • Take medicine to treat the problem that is causing low blood pressure. For example, you may need antibiotics to treat infection or medicines to stop vomiting or diarrhea.

    Your doctor may suggest that you try some simple ways to prevent symptoms like dizziness. These things may include drinking more water and limiting alcohol and caffeine.

    Low Blood Pressure Symptoms

    If your blood pressure is naturally low, it is not usually something to worry about. However, if you’re suffering from any of the below symptoms, it could be a cause for concern:

    • Feelings of nausea, dizziness or general weakness – standing or sitting up quickly could cause unsteadiness.

    • Fainting – if you experience a sudden, brief spell of unconsciousness.

    • Blurred vision – the inability to see clearly, sight will often feel as though it is out of focus.

    • Heart palpitations – when your heart beats and it is suddenly more noticeable.

    • Confusion – a person’s inability to think or speak quickly could be related to low blood pressure.

    Suffering from any of these symptoms after sudden movements, such as standing up or getting out of bed quickly is known as postural or orthostatic hypotension. If these symptoms are prominent after eating, it is known as postprandial hypotension.

    In acute cases, serious injury and shock have been cited as reasons for low blood pressure. These may include septic shock, toxic shock syndrome, anaphylactic shock and cardiogenic shock.
