Hi
Welcome to the MedHelp forum!
Chronic yawning can be the first sign of a vasovagal attack. The complex group of symptoms are mediated by the vagus nerve. This nerve is irritated by prolonged standing, standing up suddenly, stress, pain, hunger, dehydration, intense emotion etc. A tilt table test, holter monitor, echocardiogram etc are done for confirmed diagnosis.
It can also be a sign of sleep deprivation, improper sleep pattern, sleep apnea or nasal blockage. It could also be a sign of depression.
Electrolyte imbalance in the blood due to any cause like vomiting, diarrhea, kidney problems etc can cause this. Anemia too could be the cause. Chronic obstructive lung diseases like asthma too could be a cause.
On a more serious note, chronic yawning can be a sign of a brain problem like multiple sclerosis, progressive supranuclear palsy, opiate withdrawal, epilepsy, Parkinson’s disease, infection in brain or even brain tumor.
This is not something you can ignore. Do discuss this with your doctor (another one if you do not get help here) and get yourself examined. Take care!
thanks so much for your answers I am waiting to get into my doctor for an appointment, recently I've started feeling really tired no matter the amount of sleep I get, I have very low energy and am starting to get weak spells (even while sitting or lying down at times) Im wondering if any of the problems you listed above might have these symptoms as well? or could it be something completely different?
