Causes Of Low Diastolic Blood Pressure
There are three known causes of isolated diastolic hypotension:
- Alpha-blocker medications. These blood pressure medications work by causing your blood vessels to open up . Because they lower diastolic pressure more than systolic pressure, they may cause isolated diastolic hypotension. Common brand names include Minipress and Cardura.
- The aging process. As we age, we lose the elasticity of our arteries. For some older adults, arteries may become too stiff to spring back between heartbeats, causing diastolic blood pressure to be low.
- Too much salt in your diet. Dietary salt can decrease elasticity of your blood vessels. If you take in too much salt, you may increase your risk for low diastolic blood pressure.
There are several common causes of overall hypotension, which would include a low diastolic number.
- Overtreatment of high blood pressure. For some people, especially people over age 60, lowering systolic blood pressure below 120 may cause diastolic pressure to fall below 60.
Treatment Of Low Blood Pressure And Fever On The Regular Medical Floor
Your blood pressure has to be stable and improving in order to continue treatment on the medical floor. If your blood pressure goes low again, they will transfer you to the ICU right away. They will continue IV fluids and IV antibiotics and check your vital signs frequently. You will be hospitalized until your fever comes down. They may monitor you in the hospital for 24 hours or more after the last fever. If everything looks good after that, you may go home on antibiotics.
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:
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.

Can You Be Healthy And Have Low Blood Pressure
According to Luke Laffin MD, a preventive cardiologist at the Cleveland Clinic, There are many normal reasons for lower blood pressure, including younger age and small stature. Some people just have a genetic predisposition to low blood pressure.
Generally, if there are no symptoms, low blood pressure is not considered a problem. Though some people do naturally have blood pressure that tends to be on the low side and have no symptoms.
Can A Person With High Blood Pressure Also End Up With Bouts Of Low Blood Pressure
Dr. Laffin explains that treatment of hypertension can sometimes result in episodes of low blood pressure. In other words, the medication prescribed may lower blood pressure too much. Additionally, certain blood pressure medications have an increased effect if you’re dehydrated, says Dr. Laffin. For example, ARBs and ACE-inhibitors will have more of a blood pressure lowering effect if you’re dehydrated.

Treatment Of Low Diastolic Blood Pressure
Treating isolated diastolic hypotension is more difficult than treating general hypotension. If youre taking an alpha-blocker, your doctor can change you to a different high blood pressure medication.
If you have isolated low diastolic pressure and youre not on blood pressure medication, the only option may be to see your doctor more frequently for checkups and to watch for symptoms of heart failure. Currently, there isnt any medication available to treat isolated diastolic hypotension.
Treatment of general hypotension depends on the cause.
Overtreatment of high blood pressure can be managed by adjusting or changing medications. The goal is to keep the diastolic blood pressure between 60 and 90 mm Hg. Your doctor may also change other medications that cause hypotension.
Dehydration can be treated with fluid replacement. In some cases, you may need medications that increase blood pressure.
What Other Medications Can Accidentally Cause Low Blood Pressure
There are a variety of other medications that can unintentionally cause your blood pressure to drop, including cardiovascular drugs, diuretics, and beta blockers that are used to treat high blood pressure. Drugs used to treat erectile dysfunction can also result in low blood pressure, as can certain antidepressants, as well as medications prescribed for Parkinsons disease.

Symptoms Of Low Diastolic Blood Pressure
Symptoms of isolated diastolic hypotension include tiredness, dizziness, and falls.
Because low diastolic pressure decreases blood flow to your heart, you may also have chest pain or symptoms of heart failure. Heart failure symptoms may include shortness of breath, swelling of your feet or ankles, confusion, and heart palpitations.
Seek immediate medical attention if you have chest pain or difficulty breathing.
Symptoms of low diastolic blood pressure along with low systolic blood pressure include:
What Causes Low Blood Pressure
The cause of low blood pressure isn’t always clear. It may be associated with the following:
- Some prescription medicines such as for high blood pressure, depression or Parkinsonâs disease
- Heart failure
- Heart arrhythmias
- Widening, or dilation, of the blood vessels
- Severe dehydration from vomiting, diarrhea, or fever
- A reaction to medication or alcohol
- A severe allergic reaction called anaphylaxis that causes an irregular heartbeat
Who Gets Postural Hypotension?
Postural hypotension, which is low blood pressure when standing up suddenly, can happen to anyone for a variety of reasons, such as dehydration, lack of food, or being overly fatigued. It can also be influenced by genetic make-up, aging, medication, dietary and psychological factors, and acute triggers, such as infection and allergy.
Postural hypotension occurs most frequently in people who are taking drugs to control high blood pressure . It can also be related to pregnancy, strong emotions, hardening of the arteries , or diabetes. The elderly are particularly affected, especially those who have high blood pressure or autonomic nervous system dysfunction.
Hypotension after meals is a common cause of dizziness and falls after eating. This is most common after large meals containing a lot of carbohydrates. Itâs believed to be caused by blood pooling into the vessels of the stomach and intestines.
Common causes of naturally occurring postural hypotension include:

When Is Low Blood Pressure An Emergency
In many cases, low blood pressure readings are not a cause for concern. A person with low blood pressure may not even be aware that their blood pressure is low, as it does not cause symptoms in many cases.
There is also no specific cutoff point at which blood pressure becomes too low or dangerously low, as it may vary from person to person.
Some people may have chronic low blood pressure and can be otherwise healthy. The American Heart Association note that most doctors will only consider chronic low blood pressure to be dangerous if it causes other symptoms.
Severe symptoms that come on suddenly may also be a cause for concern.
While symptoms may vary from person to person, they typically include:
If a person experiences any of these symptoms, they should contact a doctor.
When blood pressure is very low or drops rapidly, it can also be a medical emergency. The note that extremely low drops in blood pressure may put the bodys organs at risk of not getting enough blood, which may lead to shock.
Some concerning signs accompanying very low blood pressure to look out for include:
- rapid, shallow breathing
- very weak but rapid pulse
- cold, clammy skin
- blue hue to the skin
Anyone experiencing these symptoms should seek emergency medical attention.
Faq #: Is Hypotension A Serious Medical Condition
Hypotension is not usually a significant medical condition. However, if there are any concerning symptoms like a loss of consciousness, mental confusion, and a weak, rapid pulse it is important you should seek immediate medical attention. Moreover, especially for people who are older, it can potentially result in accidents from fainting and falling.
This is not good news for the elderly, who potentially have brittle bones and other issues. If hypotension is not addressed, the brain, heart, and other organs will be deprived of blood and will be unable to function correctly. Shock, which can be lethal, can result from severe hypotension.

Ayurvedic Remedies For Low Blood Pressure
According to Ayurveda, low blood pressure is caused by vitiation of vayu in the body. It considers a nutritious, balanced diet with proteins and carbohydrates to be helpful for people with this condition. Dry fruits, chicken, rabbit, mutton, soups of black gram and meat, legumes, and fruits like mangoes, apples, bananas, and grapes are especially recommended. People with low blood pressure are also advised to avoid strenuous exercise.17
Stroke And Brain Problems
High blood pressure can cause the arteries that supply blood and oxygen to the brain to burst or be blocked, causing a stroke. Brain cells die during a;stroke;because they do not get enough oxygen. Stroke can cause serious disabilities in speech, movement, and other basic activities. A stroke can also kill you.
Having high blood pressure, especially in midlife, is linked to having poorer cognitive function and dementia later in life. Learn more about the link between high blood pressure and dementia from the National Institutes of Healths Mind Your Risks®external icon;campaign.
Symptoms Of High Blood Pressure
Even though high blood pressure levels can negatively affect the body, it typically doesnt cause symptoms until it leads to a serious health problem like a stroke or heart attack. This is why its sometimes referred to as the silent killer. When it does cause symptoms and side effects, people with high blood pressure may experience one or more of the following:;;;
- Irregular heartbeat
- Blood in the urine;
If you have any of these symptoms, it doesnt necessarily mean that your blood pressure is too high. Some people will have one or more of these symptoms for unrelated reasons, so its always a good idea to check your blood pressure on a regular basis.;
What Can Cause Low Blood Pressure
Factors that can cause low blood pressure include:
- Medical conditions like heart problems, hormonal problems, septic shock, neurological disorders, anemia etc.
- Certain medications for instance, some antidepressants or beta blockers prescribed for heart conditions
- Blood pressure tends to drop during the first twenty-four weeks of pregnancy.34

What To Do If You Experience A Sudden Drop In Blood Pressure
A single low blood pressure reading is no cause to be concerned unless you experience other symptoms.
A sudden drop in blood pressure as little as a drop from 120 to 100 in your systolic number can be dangerous if it triggers dizziness and fainting. Such symptoms can be a sign of an underlying problem that may need medical attention.
You should keep a record of your activities and when symptoms happen to discuss them with your doctor. If you experience any low blood pressure symptoms related to shock, you should seek immediate medical attention.
What Can I Do To Prevent Or Manage High Blood Pressure
Many people with high blood pressure can lower their blood pressure into a healthy range or keep their numbers in a healthy range by making lifestyle changes. Talk with your health care team about
- Getting at least 150 minutes of physical activity each week

Improving Health With Current Research
Learn about the following ways the NHLBI continues to translate current research into improved health for people with abnormally low blood pressure. Research on this topic is part of the NHLBIs broader commitment to advancing heart and vascular disease scientific discovery.
- Testing Treatments for Cardiac Arrest and Trauma. The Resuscitation Outcomes Consortium clinical trial network tested treatments to address high morbidity and mortality rates from out-of-hospital cardiac arrest and severe traumatic injury. ROC investigators compared different strategies for supplemental fluids in trauma patients who have low blood pressure. Other ROC studies found a link between low blood pressure readings and the need for emergency procedures.
- Understanding How Low Blood Pressure Affects Diverse Populations. NHLBI-supported researchers are studying low blood pressure in different populations. Investigators in the NHLBIs Atherosclerosis Risk in Communities Study found that people who have low blood pressure when standing up, known as orthostatic hypotension, are at higher risk for stroke. In a follow-up study of NHLBIs Honolulu Heart Program, researchers found older Japanese men who had orthostatic hypotension were nearly twice as likely to die within the next four years as those who did not have orthostatic hypotension. NHLBIs Cardiovascular Health Study found that orthostatic hypotension was common in older adults, increases with age, and is linked to cardiovascular diseases.
Serious Injuries And Shock
Low blood pressure can also be caused by serious injuries or burns, particularly if you have lost a lot of blood. This can mean that there is less blood being pumped around your body. Low blood pressure can also occur if you go into;shock after having a serious injury.
Other kinds of shock are described below.
Anaphylactic shock, or anaphylaxis, is caused by an allergic reaction to something – for example, a wasp sting or a peanut. During an allergic reaction, your body produces a large amount of a chemical called histamine, which causes your blood vessels to widen and leads to a sudden, severe drop in blood pressure.
Cardiogenic shock occurs when your heart cannot supply enough blood to your body, so your blood pressure drops. This can happen during a heart attack.

What Is Low Blood Pressure
Hypotension is the medical term for low blood pressure .
A blood pressure reading appears as two numbers. The first and higher of the two is a measure of systolic pressure, or the pressure in the arteries when the heart beats and fills them with blood. The second number measures diastolic pressure, or the pressure in the arteries when the heart rests between beats.
Optimal blood pressure is less than 120/80 . In healthy people, low blood pressure without any symptoms is not usually a concern and does not need to be treated. But low blood pressure can be a sign of an underlying problem — especially in the elderly — where it may cause inadequate blood flow to the heart, brain, and other vital organs.
Chronic low blood pressure with no symptoms is almost never serious. But health problems can occur when blood pressure drops suddenly and the brain is deprived of an adequate blood supply. This can lead to dizziness or lightheadedness. Sudden drops in blood pressure most commonly occur in someone who’s rising from a lying down or sitting position to standing. This kind of low blood pressure is known as postural hypotension or orthostatic hypotension. Another type of low blood pressure can occur when someone stands for a long period of time. This is called neurally mediated hypotension.
