Neurally mediated hypotension syndrome (NMHS) is also known by the following names: the fainting reflex, neurocardiogenic syncope, vasodepressor syncope, the vaso-vagal reflex, and autonomic dysfunction, orthostatic hypotension variety. Hypotension is the formal medical term for low blood pressure, and syncope is the term for fainting.
NMHS is a condition of sudden decrease in blood pressure that causes light-headedness, nausea and sometimes fainting. It is very common in people with CFS. It occurs when the usual mechanisms for maintaining blood pressure fail. Normally, when a person stands, blood pressure is increased to keep blood flowing to the head.
In patients with NMHS, this process is reversed and blood pressure falls. Dizziness or fainting can also be caused by the release of adrenaline.
NMHS occurs in susceptible individuals in the following settings:
- after prolonged periods of quiet upright posture (such as standing in line, standing in a shower, or even sitting up for long periods)
- after being in a warm environment (such as in hot summer weather, a hot crowded room, a hot shower or bath)
- after exercise
- after emotionally stressful events (seeing blood or gory scenes, being scared or anxious).
- some individuals get symptoms soon after eating, when blood flow has shifted to the intestinal circulation during the process of digestion
Patients that do not response well to standard treatment recommendations (increasing blood volume through the consumption of more fluids and salt, wearing support hose, avoiding long periods of standing) may be benefit from the comprehensive treatment protocol designed by Carmen Care Advanced Laser Therapy which include Laser Energy Detoxification and photobiomodulation.
