Well, it is true, and it can be very confusing and potentially harmful if not identified and treated.
This condition is called Neurally Mediated Hypotension (NMH), also known as the fainting reflex and autonomic dysfunction, and it is a condition which involves miscommunication between the heart and the brain.
A researcher into this phenomenon recently stated: “We think that in these patients, the heart is generally normal and the brain is normal, but the reflex interaction between the two is what is out of kilter. And what seems to trigger that dysfunction is a state of a low amount of blood in the ventricle of the heart while standing. It is either low because you’ve started with a lesser volume of blood, for whatever reason, or because the amount of effective blood volume that is potentially available is not getting delivered to the heart because of an excessive amount of pooling in the extremities.” We are referring here to an “autonomic nervous system disorder”.
The Autonomic Nervous System (ANS)is the chief regulator of organ function throughout the body and is involved in many vital functions such as controlling the heart rate, blood pressure, temperature, respiration and digestion to name a few.
When the autonomic nervous system is challenged, it can produce what appears to be a malfunction of the organs it regulates. Therefore, patients with a damaged ANS will display numerous unrelated maladies.
One of them is a high pulse rate but a very low blood pressure also described as follows: Chronic Orthostatic Intolerance produces day-to-day symptoms including dizziness and often altered vision (blurred, ‘white outs’, ‘black-outs’), fatigue, nausea, neurocognitive deficits, disordered thermoregulation, palpitations, high pulse low blood pressure, headache, tremulousness, hyperpnoea, difficulty breathing, sweating, and pallor.
For those who are afflicted with Orthostatic Intolerance, there is an excessive increase in heart rate upon standing, resulting in the cardiovascular system working harder to maintain blood pressure and blood flow to the brain.
This condition is one of the least understood of the autonomic disorders and is often misdiagnosed as anxiety or psychiatric problems because of the nature of the symptoms.
Another interesting “NHS” is “POTS” Postural Orthostatic Tachycardia
Chronic Orthostatic Intolerance is associated with Postural Orthostatic Tachycardia Syndrome (POTS). Postural Orthostatic Tachycardia is a syndrome.
And as such, there is an array of symptoms that accompany it. Because the Autonomic Nervous System plays a large role in regulating certain functions throughout the body, the symptoms are widespread. Symptoms will vary from person to person and will include some of the following: palpitations, dizziness, lightheadedness, exercise intolerance, blurred vision, chest pain, high pulse low blood pressure, fainting, fatigue, migraines, blood pooling in limbs, cognitive impairment, gastric discomfort and sleep disorders among others.
The onset of POTS often follows a viral infection or other inflammatory condition. It affects an unknown number of patients, mostly female, between the ages of 12 and 50.
The name Neuropathy is given to a group of disorders involving nerves. The symptoms range from a tingling sensation or numbness in the toes and fingers to paralysis.
Neuropathy is a problem in peripheral nerve function (any part of the nervous system except the brain and spinal cord) that causes pain, numbness, tingling, swelling, and muscle weakness in various parts of the body.
Symptoms include disturbances of blood pressure, heart rate, or bladder and bowel control, muscle weakness, impotence; loss of balance; sensitivity to touch, tingling, extreme pain, reduced ability to perspire, constipation, bladder dysfunction, burning sensation, and inability to focus the eyes depending of which nerves are affected.
In general, it is not well understood what causes Neurally Mediated Hypotension, but doctors have long suspected that its origin may be genetic because these syndromes seem to run in families.
NHS can be triggered in anyone under extreme circumstances. Doctors believe that potentially we could all trigger NHS if we experience extreme heat, stand for long periods of time, suffer from malnutrition or don’t drink enough fluids. Some people experience it every time they get their blood drawn.
NHS, a very interesting set of circumstances that can cause ANS if you feel you may be experiences ANS see your physician quickly.
