alarm reaction

the first stage of the general adaptation syndrome; the response of the sympathetic nervous system to either physical stress or a strong emotional state (see also stress reaction). It is an automatic and instantaneous response that increases the body's capability to cope with a sudden emergency. The physiologic changes that occur increase physical strength and mental activity. The blood pressure is elevated, the blood glucose level is raised for additional energy, the blood coagulates more readily, and the flow of blood to muscles needed for activity is increased, while those organs not needed for “fight” or “flight” receive a diminished blood supply. One of the most striking manifestations of this reaction is the involution of lymphoid tissues due to the action of adrenal hormones. Called also sympathetic stress reaction and fight-or-flight reaction.

Patient discussion about alarm reaction

Q. is there cause for alarm if i have a white thick discharge?

A. Hello, ruffdee, if the discharge is white, and NOT causing any itchy feeling, burn sensation, and not smelly, it probably still is in normal range.
But once you feel itchy, burning, its color turns yellowish or greenish, and it has bad smell, it might be a sign for an infection, and it is recommended then you to find a doctor to get the specific therapy to cure the infection.

Q. How do you wake up in the morning if your narcolepsy is so severe you can't hear the alarm clock, phone ring? biggest problem is sleep paralysis, can't wake up. Late for work, everything, life is suffering because of severity. Have tried ritalin, natural supplements, hypnosis therapy, Provigal, antidepressants, nothing seems to work. Employer thinks it's an excuse, friends are irritated, I'm at my wits end. Life is spent sleeping more than awake.

A. Narcolepsy cannot yet be cured. But EDS and cataplexy, the most disabling symptoms of the disorder, can be controlled in most patients with drug treatment. Often the treatment regimen is modified as symptoms change. For decades, doctors have used central nervous system stimulants-amphetamines such as methylphenidate, dextroamphetamine, methamphetamine, and pemoline-to alleviate EDS and reduce the incidence of sleep attacks. For most patients these medications are generally quite effective at reducing daytime drowsiness and improving levels of alertness. However, they are associated with a wide array of undesirable side effects so their use must be carefully monitored. Common side effects include irritability and nervousness, shakiness, disturbances in heart rhythm, stomach upset, nighttime sleep disruption, and anorexia. For full article: Hope this helps.
