There are three broad categories of causes: heart or blood vessel related; reflex, also known as neurally mediated; and orthostatic hypotension. [1] Issues with the heart and blood vessels are the cause in about 10% and typically the most serious while neurally mediated is the most common. [1] There also seems to be a genetic component to syncope.
The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3] Recovery from a reflex syncope episode happens without specific treatment. [2]
This happens via blood flow, the inhalation of cool air, and the occasional tearing of the eyes. It has also been found that yawning occurs before, during, and after instances of abnormal ...
Return of systemic blood to the heart is impeded by the pressure inside the chest. The output of the heart is reduced, and stroke volume falls. This occurs from 5 to about 14 seconds in the illustration. The fall in stroke volume reflexively causes blood vessels to constrict with some rise in pressure (15 to 20 seconds).
Alas, you can add one more unpleasant side effect to the list: persistent and particularly malodorous belching. So what are Ozempic burps, exactly? Read on for the full scoop from a medical expert ...
Yawning. We all do it and yet there's no set explanation on why we do it. And just as mysterious is that the act of yawning seems to be contagious. A new study looking at that issue has found that ...
He [Prophet Muhammad] likened excessive yawning to the howling of dogs to deter people from it and to make it seem repulsive, for when a dog howls, it raises its head and opens its mouth widely, and the yawner resembles it when he yawns too much. This is why the Devil laughs at those who yawn, for he succeeds in playing with them and deforming ...
Aerophagia (or aerophagy) is a condition of excessive air swallowing, which goes to the stomach instead of the lungs.Aerophagia may also refer to an unusual condition where the primary symptom is excessive flatus (farting), belching (burping) is not present, and the actual mechanism by which air enters the gut is obscure or unknown.
