It is not uncommon for people to report feelings of morning dizziness from time to time. Dizziness can emerge from many underlying causes, some benign and others more serious. A feeling of dizziness is purely subjective; the term is used to describe specific sensations among which much variation exists. Low blood sugar is sometimes, but not always, a cause of dizziness felt in the morning.
Feeling lightheaded is commonly cited as a specific feeling which accompanies dizziness. This sensation can range from mild to quite strong and is often compared to feeling slightly weak, tired and physically off-kilter. Individuals often feel lightheadedness in combination with other symptoms and sensations of dizziness, typically upon arising or shortly afterward. Morning lightheadedness can be related to a number of underlying factors, such as some medicines, changes in blood pressure and low blood sugar.
Problems with Balance
Another key feature of dizziness is the sensation of feeling off-balance. Like lightheadedness, a problem with balance usually occurs in concert with other sensations and can be indistinguishable from them, as they often occur simultaneously and complicate each other. Although either feeling can precipitate the other, difficulty balancing often follows feeling lightheadedness or the sensation of vertigo or both.
MedLine Plus describes vertigo as a sensation that the room is spinning around. Vertigo can be very uncomfortable and is almost always accompanied by feeling off-balance. While vertigo is often a symptom of other diseases, it is also a condition that occurs by itself and is caused by problems of the inner ear, which are instrumental in regulating balance.
According to Dizziness-and-balance.com, one example of this kind of vertigo is benign paroxysmal positional vertigo, a common condition caused by the presence of collecting debris in the inner ear. It is estimated that 20 percent of all dizziness is caused by this condition, which is triggered by postural changes in head position relative to gravity.
Often when dizziness is related to a sudden drop in blood pressure or low blood sugar, a person can feel as if he is going to "pass out" or faint. This can be a terribly uncomfortable and anxiety-provoking feeling often characterized by one or more of the aforementioned symptoms. It can also include nausea, weakness, increased perspiration and changes in vision and hearing. While fainting itself is not usually harmful, serious injury can result if a person falls.
