Q: What causes low blood pressure?
I was recently diagnosed with vasovagal syncope and low blood pressure. What causes low blood pressure? They told me to increase salt and fluid intake but is the only cause of low blood pressure low salt/fluid?

What else can I do?
Thanks
I don’t go to the doctor, wookie.

The doctors have not been very helpful so far.

A: 10-1 there have been other factors ruled out by blood test.
Let me explain why salt and fluid intake have been suggested.

The main reason low blood pressure occurs is because a lack of blood volume, not enough blood, usually due to trauma or such. about 30& of blood is made of red blood cells, the rest is plasma. Blood plasma is made of primary water.

So increasing fluid intake would increase blood volume, there by raising blood pressure. The salt will help retain the water and raise electrolyte levels.

Q: What causes low blood pressure to sky rocket to high blood pressure?
My blood pressure is usually right around the “normal” 120/80 and I was feeling really tired this morning and I took my blood pressure and it was 80/53 so I got a little worried and then I ate a small bowl of veggie soup and then took it again and it jumped all the way up to 163/108. What could have caused that?

A: Your condition is called Labile Hypertension. Read on…..

Labile hypertension is a subcategory of hypertension (high blood pressure). It is characterised by abrupt and repeated fluctuations in blood pressure levels. At times this fluctuation can range from 119/76 mm Hg in the morning to 170/104 mm Hg in the afternoon.

Is the Threat Real?

The threat posed by labile hypertension is real. Though unlike others individuals suffering from labile hypertension never show symptoms of suffering from it, the fact still remains that they continue to silently suffer from it. Even otherwise the surge in blood pressure seems to be insignificant (as it is gradual) but in reality it is dangerous.

People who get regularly affected by labile hypertension (from different types of causes) can experience the same type of damages suffered by those with resident hypertension (hypertension as a part of their life).

There are different causes of labile hypertension. These include factors such as anxiety attacks, too much consumption of caffeine, salt sensitivity, or stress
overload. The causes might be different but the health implication of labile hypertension is the same in all cases- it poses a serious threat to the life of the individual. Hence, it is absolutely necessary to treat this condition.

It is safe to get a complete cardio check to see if there is any problem. Good luck.

Q: What causes low blood pressure and low heart beat?
Everytime I give blood the nurse testing my blood pressure calls for the RN to recheck me. Then she asks me questions like if I’m a marathon runner or if I’m very athletic. I’m also a free bleeder and bleed alot from even small wounds.

From what I pick up from the nurses it’s a good thing but I’m just curious about it.

My blood pressure is like 100/60 and my heart beats around 45bpm at rest, I would think this would help live a long life because my heart doesn’t work very hard.

I’ve taking probably 10 polygraph tests also and they have a hard time just registering a heart beat sometimes because I relax so much while taking them, they’ll stop in the middle of it and ask if I’m still alive.

Thanks for your answers

A: The second figure (60 in your case) indicates the pressure left in your veins after the heart beats. If this is low, then less pressure is being exerted overall on your circulatory system, so that’s a good thing. The first number (100) shows what pressure the heart is exerting when it beats – if you have coronary or other circulatory problems, the veins and arteries might be partially blocked, in which case, the heart has to work much harder to get the blood to flow through your body, and the pressure exerted can be high enough to rupture or damage blood vessels. This is the danger of high blood pressure.

I’m not sure why they are particularly surprised at your blood pressure. I’m a healthy man in my 50’s and my blood pressure has been 110/70, or occasionally 120/80 for the last 30 years.

Marathon runners/athletes train hard and both increase the power of their heart, and reduce the resistance to blood flow in the body, so their blood pressure might be even lower than yours.

In general, if you are in good health, and take regular exercise, your at-rest pulse should be around 60-70 bpm. Your at rest pulse is indeed more like that of a very healthy athlete – you are lucky!

They should be happy that your heart is in good condition and your blood pressure is well within the normal range.

Q: What Causes Low Blood Pressure?
I have recently found out that i have low blood pressure and low iron, i have heard that this is a bad combonation and i am trying to gain a better understanding of why? and what causes low blood pressure, how to fix it and can it cause chest pains and dizziness?

A: For the most part, low blood pressure, or hypotension, is considered to be a sign of good health. This is because higher blood pressure places more pressure is on the heart and the circulatory system. For this reason, individuals with low blood pressure are usually at a lower risk of kidney disease, stroke, and heart disease. In some cases, however, low blood pressure may not be healthy and, like high blood pressure, carries some risks.

With very low blood pressure, the brain, heart, and other vital organs may not receive enough blood. Ultimately, this can cause these organs to fail to function properly and even to become permanently damaged. The lack of oxygen can also cause a person with low blood pressure to experience blackouts, particularly when standing up or sitting up too quickly after lying down. This type of low blood pressure is generally referred to as orthostatic hypotension.

Low blood pressure can also be a symptom of a variety of conditions, some of which are life threatening. These conditions include dehydration, shock, advanced diabetes, heart failure, heart attack, and anaphylaxia, a life threatening allergic response. While low blood pressure does not cause these conditions, it can sometimes be the first sign of them.

For a person to be diagnosed as having low blood pressure, his or her blood pressure must be below 90/60. Normal blood pressure is considered to be anywhere from 90/60 to 120/80. It is possible for only one of these numbers to be less than the normal range. In this case, the person may still be considered to have low blood pressure.

Regardless of the blood pressure reading, doctors do not usually diagnose a person with low blood pressure unless he or she is showing other signs or problems associated with low blood pressure. Some of these signs include dizziness, lightheadedness, and fainting for no apparent reason. Since blood pressure that is low enough to cause health problems is usually caused by other health problems, the first treatment plan is to treat the underlying cause of the low blood pressure. If there is no underlying cause, certain medications may be prescribed to regulate the blood pressure.

Q: suggest ten possible causes of low blood pressure based on the factors that maintain normal blood pressure?
Blood Pressure = Cardiac Output x Total Peripheral Resistance
if you don’t mind please describe whether the causes are hypovolemic, cardiologic, distributive, obstructive, or neurogenic.
(highest rating to the quick and best answer)

A: Possible causes of low blood pressure

Distributive (Excessive vasodilation, a hyper dynamic process)

# Septic Shock
# Systemic inflammatory response syndrome (SIRS) due to noninfectious inflammatory conditions like burns & pancreatitis;
# Toxic shock syndrome (TSS);
# anaphylaxis; drug or toxin reactions, including insect bites, transfusion reaction, and heavy metal poisoning;
# Addisonian crisis;
# Aepatic insufficiency;
# Neurogenic shock due to brain or spinal cord injury.

Cardiogenic

# Following acute myocardial infarction (MI).
# acute coronary syndrome or unstable angina).
# Pericarditis
# A slow heart rate (bradycardia)
# Cardiac arrhythmias

Hypovolemic

# Hemorrhagic shock.
# Dehydration is common among patients with prolonged nausea, vomiting, and diarrhea.Other causes of dehydration include exercise, sweating, fever, and heat exhaustion, or heat stroke.

Obstructive shock

# Pulmonary Embolism
# cardiac tamponade
# Narrowing of the aorta.

Neurogenic shock
# Due to brain or spinal cord injury

Q: How do antidepressants cause low blood pressure?
Ive read on the internet they do and i am doing a assignment and one of the sections is on blood pressure. I cant find anywhere how it causes lo pressure though…
Any help???

A: Tricyclic antidepressants can cause low blood pressure (particularly postural hypotention) in about 17 in 100 people. Low BP is only ever a problem if you are symptomatic. It is due to the anticholinergic effects of the medication. Postural hypotension associated with antidepressant medication is generally caused by a failure of reflex peripheral vasoconstriction.

Q: What are 10 possible causes of low blood pressure?
For each of the causes which term applies to it: cardiogenic, neurogenic, hypovolemic, distributive or obstructive?

A: Cardiogenic (heart related) orthostatic hypotension. In this instance the heart doesn’t respond adequately to demands for greater pumping and blood pressure drops. Conditions such as arrhythmia, heart failure, deconditioning, and pregnancy are examples.
Hypovolemic – Low blood volume (e.g. anemia, dehydration, dialysis)
Medication related (usually too high doses of blood pressure medications or medications for depression)
Primary adrenal insufficiency.
Neurogenic orthostatic hypotension
. Sensory neuropathies (diabetes, alcohol, syphilis, Holmes-Adie syndrome, carotid sinus obliteration by endarterectomy, Riley-Day syndrome)
Multiple system atrophy or Shy-Drager, Parkinson’s, dementia with Lewy bodies. Patients with MSA have intact sympathetic noradrenergic innervation.
Medullary strokes or injuries
Peripheral neuropathy, especially diabetes and amyloidosis
PAF – pure autonomic failure or idiopathic orthostatic hypotension.
Dopamine beta-hydroxylase deficiency

Q: what causes low blood pressure?
well im 15, and sometimes when im lying down on the couch and get up, [its not a quick motion] 15 seconds later i feel like im going to faint. my vision gets a little blurry, my vision gets kinda black but slowly goes back to normal, and i loose my balance. i feel like im actually going to faint one day. the feeling lasts anywhere from 15-40 seconds. i exercise daily, and all i drink is water, and cranberry juice. then someone said this is caused by a drop in blood pressure, and that i may even have low blood pressure. what causes this and how does this affect my body? also, they said anemia is a possibility, what is that? i know of nobody in my family who has this kind of problem, so i feel kinda lost. i plan on going to a see a doctor soon =/ thanks for the help i appreciate it

A: drink something that is osmotically balanced like gatorade (has both sugar and salt) this will increase the volume of your blood. you are also growing. all normal.

Q: Other than low iron, what are the causes of low blood pressure?
I have a normal resting heart rate. I’m not on any medication. Everything about my blood work is normal. I’m not often dehydrated.

?

A: Do you get enough salt in your diet?

Love your new back-up account!

Q: What are the causes of low blood pressure and how can it be treated?

A: Causes

There are a variety of factors that can lead to low blood pressure:

Pregnancy – Blood pressure commonly drops by as much as 5-10 points systolic and 10-15 diastolic during the first 24 weeks of pregnancy due to the expansion of the woman’s circulatory system
Medications – Not surprisingly, many drugs used to treat hypertension (high blood pressure) and heart disease can trigger unexpectedly low blood pressure. Your doctor may need to adjust your dosage and/or medication. Other drugs to treat Parkinson’s disease, depression, and erectile dysfunction (e.g. Viagra) can also cause low blood pressure.
Heart Problems – Heart problems such as bradycardia (low heart beat rate), heart valve problems, and heart attack/failure can lead to low blood pressure. In these conditions, the heart is not able to pump enough blood.
Endocrine Problems – Thyroid problems (underactive or overactive), Addison’s disease (adrenal insufficiency), low blood sugar, and diabetes can all trigger low blood pressure.
Dehydration – In dehydration, your body loses more water than you take in. Dehydration is usually a result of diarrhea, vomiting, diuretic overuse, and strenuous exercise. The drop in volume can cause weakness, dizziness, and fatigue.
Nutritional Deficiencies – Deficiencies in vitamin B-12 and folic acid can lead to anemia, which then in turn can lead to low blood pressure
You need to keep it monitored with your MD or healthcare professional on a regular basis to determine a course of action.

Q: Can chickenpox cause very low blood pressure?
Or would this be an indication of another underlying condition that required investigating? I realise it’s difficult to know without knowing full patient details but in general, can
chickenpox cause low blood pressure? Does it happen often? By the way I’m
referring to an adult not a child.
By the way I should also add that the young adult is otherwise fit and healthy

A: chicken pox by itself will not cause low blood pressure.
in acute state because of high fever and irritability and some times vomiting(chicken pox affects intestines also) leading to dehydration and electrolyte imbalance .patient will not take food and fluids and even water also.
hence low blood pressure.

Q: What are the causes of having Low Blood Pressure?
Is it as bad as having high blood pressure?

A: Both low and high are bad. If you always have low blood pressure then it may just be normal for you.

The causes for low blood pressure are:
Dehydration
Skipping a meal
Pregnancy
Medications
Heart problems
Severe infection

The good thing is that some people just have normal low blood pressure. But if you never had it before then you should talk to a doctor.

Q: low blood pressure, causes??
So I just test my blood pressure, with one of those at home things, and the numbers said 100/63 with an 83bpm. I did another test, and it came out 105/63 with 83bpm. My mom said that its low, so did the arrow on the monitor.

What I want to know, is what could be causing my blood pressure to be that low. I’m 18, 124 lbs, and I was born premature, first week of the 8th month, if thats of any help. Also, my mom had really high blood pressure when she was in labor with me.

I’m just curious about why my blood pressure could be so low, my doctors have said that i’m fine, but I know something is up, because I don’t drink coffee in the morning, rather I rarely do, and I am always wanting to sleep, especially in class. During the week, i sleep an average of about 5-6 hours a night, but the rest I make up for on the weekends (sat & sun).

thank you for the answers in advance. =)

A: Low blood pressure in an otherwise healthy adult is usually caused by dehydration. Are you drinking enough fluids during the day?

Q: What can cause low blood pressure, low potassium and low iron levels in 21 weeks of pregnancy?
I did ask my doctor, he hospitalized me and couldn’t find the reason. I have to see him again next week. My god why do people find the need to answer just to be RUDE!

A: You are providing nutrition for you AND YOUR FETUS–you need your doctor to advise on adding to your daily diet. Suggestions on a public site are not going to be of any value. Pregnancy changes a woman’s body–that is not so hard to understand–you need to stay in touch with your doctor and note all of your changes as they occur. Do not add things to your diet that are not beneficial–do not guess at what forms of sugar and vitamins and minerals you MAY need. Every woman is different–a thousand pregnant women can have a thousand different changes as the pregnancy develops. Relax–Good luck to you.

Q: Renal functions. Patient has extemely low blood pressure caused by congestive heart failure; what is the cause?
A patient has extremely low blood pressure caused by congestive heart failure; unable to provide a urine sample. Patient reports that they have not urinated for two days. Patient is extremely weak and feels terrible. Blood work show elevated levels of urea and imbalance of electroylytes. What is the cause focussing on Renal Functions?

A: I think you should go back to medical college, if you’re asking Yahoo.
