Celebral Blood Flow Restriction
I would start: With cta of the head and neck. ...Read more
Echo saging of the body of AMVL, normal blood flow, trivial MR. Restrictions? Can I live normal and do everything? Only symp skip beats waning/waxing
MVP: Such mild prolapse of the mitral valve is common and should not impact your physical activities, although atrial irritability certainly may occur. You could have a treadmill exercise stress test to see if strenuous physical exertion precipitates significant cardiac rhythm disturbances. Passing such a test will give you peace of mind. I recommend echocardiography every year or two to monitor mvp ...Read more
Tumors need nutrient: When tumors grow in the brain, they make new blood vessels (angiogenesis). These vessels are not normal compared to the non-tumor vessels. As a result, more blood flows into the tumor, which allows for more tumor growth. Since there is more flow, at any given time there is more blood volume in the tumor. Occasionally, there may be so much flow that it can shunt, or divert, flow from normal brain. ...Read more
Not exactly: The flow to the anterior cerebral starts at the heart, goes up the ascending aorta, to carotid arteries which reach the Circle of Willis, and go to anterior cerebral, middle cerebral and posterior cerebral arteries. Anterior communicating can be viewed as a bridging collateral. ...Read more
Is there anyway to see if cerebral blood flow is reduced when standing? Got dysautonomia and suspect cerebral vasoconstriction is too excessive
Dysautonomia: Dysautonomia syndrome causes different symptoms alleviated by avoidance of stimulants, ensuring hydration, using magnesium, vitamin D & omega fish oils (www. Cardiamin. Com, use code: CMC), low dose beta blockers e.g. propranolol 5 to 10mg 2 to 3 times daily and SSRIs e.g. citalopram 5 to 10mg daily. Read Dr. Ronald Hoffman’s MVP book (www. Amazon. Com) and visit www. Dysautonomiainternational. Com. ...Read more
Studies show caffeine reduces Cerebral BloodFlow 27-40%... does this mean caffeine is damaging brain cells? Why not? Reduced blood flow is NOT good!?!
If that were: The whole truth, caffeine would not be the most widely used psychoactive agent on Earth. Caffeine also enhances alertness, enhances mental focus and improves score for all comers in tests of performance and cognition. So, this is what happens when you take one isolated physiologic response and try to then conclude something more complex about cell function, especially the brain. Neurobiology=??? ...Read more
Actually pH: The pCO2 affects the intracerebral acid/base balance which governs auto-regulation. ...Read more
Best diagnostic to detect vasoconstriction and reduced cerebral blood flow? Transcranial doppler?
Would chronically high catecholamines inducing vasoconstriction result in reduced Cerebral Blood Flow and Hypoxia? Why or why not?
Do beta-blockers decrease cerebral blood flow? What meds increase cerebral blood flow through cerebral vasodilation?
What R the lasting effects of a years worth of reduced cerebral blood flow due to vasoconstriction? Does the lack of proper CBF result in cell death?
Cancer and blood flo: Many cancers elaborate factors that enable the growth of new blood vessels. In this way they gain an advantage in growth. When seen clinically on radiologic tests, this is a marker of malignancy and agressiveness, especially in the brain where low grade tumors only do this to a mild degree. Some cancers are treated by agents that interrupt this process, hoping to "starve" them of nutrients. ...Read more
Please explain what it means when there is increased cerebral blood volume and blood flow in a brain tumor?
Is there any drug that selectively increases cerebral blood flow but does not effect systemic blood pressure or heart rate?
Unlikely: I am not aware of such a drug. I am not sure why you might want this. There is not a specific way to do this and many drugs are able to cross the blood brain barrier. See your doctor if you have any symptoms you cannot complain. ...Read more
I've taken. 1mg clonidine 2x/day one week, all week head felt heavy, vision blurry, tapering off it. Is reduced cerebral blood flow permanent effect?
Nifedipine vs Nicardipine for Cerebral Vasodilating and Cerebral Blood flow? The literature says Nicardipine but it's not prescribed often right?
Nicardipine: These two meds are from the same class. Both vasodilate arteries and arterioles, both drop blood pressure, both are designed to have little or minimal effect on myocardial muscle contraction and cardiac conduction systems. Mg vs mg, nicardipine is slightly more potent in these vasodilating actions. The formulations account for this difference, as hypotension is the chief risk and hazard. ...Read more
What cerebral blood flow increasing drugs should I ask my neurologist about if I am having blood vessel constrictive issues effective my mental state?
Dysautonomia causes over vasoconstriction in brain & reduced cerebral blood flow. Is there any vasodilator drugs I can ask my doctor about for this?
Stenosis is the narrowing of a blood vessel that alters normal perfusion. Examples of stenosis in the vascular system are renal artery stenosis or carotid artery stenosis.
The development of atherosclerotic plaques sometimes occludes so much of a blood vessel that stenosis occurs. ...Read more
Yes. In the brain.: Hypercapnea does increase blood flow in the brain by causing cerebral vessel vasodilation. This is part of a process in the brain termed cerebral autoregulation. It also can lead to peripheral vasodilation by direct effects on blood vessels. This may also lead to increased blood flow. However, this would not be a desirable effect for anything other than the body's normal response to changes in ph. ...Read more
Kidney blood flow:
1. Fall in BP
2. Narrowing of arteries to kidney
3. Diseases of glomeruli
4. Salt depletion
5. Drugs like aces or arbs ...Read more
You cant: Everbody is different in the amount that they bleed each month. There is no way to increase the amount of flow that one person has. If you are not getting a period at all, then we can place you on birth control pills to induce a cycle. ...Read more
Many things!: Menstrual flow can be altered by a large number of things. Increased blood flow can be due to fibroids, adenomyosis, endometriosis, bleeding/clotting problems, and uterine polyps, increased estrogen, and MANY OTHER things. Be sure to follow-up with your OB/GYN or primary care physician if you are experiencing changes in menstrual bleeding. ...Read more
Cayenne, Ginger,: Garlic, and Ginkgo are all blood thinners or interact w/prescription blood thinners. Thus, it is very important that you speak w/your doctor about taking these, especially in combo and if you are on a prescription blood thinner. Taking all of the above can be dangerous and produce bleeding. Peace and good health. ...Read more
Ginkgo Biloba: Is used to open up blood vessels and thus increase blood flow. Please consult your doctor before using. If you are on a blood thinner it can be dangerous. Peace and good health. ...Read more
Period: Hi, usually people try to decrease the bleeding during period so why do you want to increase the bleeding? ...Read more
A few: Sometimes being cold or dehydrated can do this. ...Read more
Yes: Blood flow to heart & lungs increase during exercise in order to improve oxygenation of muscles. Blood flow also increases to remove metabolic waste which you can feel as "burn" sensation after strenuous exercise. ...Read more
No: Difficult to do with the liver's circulation, but if theoretically all blood flow stopped, it would die, then "rot" (/necrose) and degeneration/waste products would build up in the body, making it toxic and eventually causing heart function / rhythm problem and death. Likely 3-10 days? ...Read more
