The last few mornings I have been feeling light-headed when I get up, can anyone shed any light on why this could be? If this continues I shall have to see my doctor but thought I would ask here to see if anyone could answer.

I am not a doctor or have any background in the medical field. This is INFORMATIONAL ONLY. Consult with your medical provider for concrete diagnosis

Light-headedness is a common and often unpleasant sensation of dizziness and/or feeling that one may be about to faint, which may be transient, recurrent, or occasionally chronic. In some cases, the individual may feel as though his or her head is weightless. The individual may also feel as though the room is "spinning" or moving (vertigo). Most causes of dizziness are not serious and either cure themselves quickly or are easily treated.

Keeping a sense of balance depends on the brain processing a variety of information from the eyes, the nervous system and the inner ears. However, if the brain can't process signals from all of these locations, if the messages are contradictory, or if the sensory systems aren't functioning properly, an individual may experience dizziness and loss of balance.

Light-headedness can be simply an indication of a temporary shortage of blood or oxygen to the brain due to a drop in blood pressure or rapid dehydration from vomiting, diarrhea or fever. Other causes are low blood sugar and anaemia. It can also be a symptom of many other conditions, some of them serious, such as heart problems (including abnormal heart rhythm or heart attack) and also stroke, bleeding and shock. If any of these serious disorders are present, the individual will usually have additional symptoms such as chest pain, a feeling of a racing heart, loss of speech or change in vision.

Many people, especially as they age, experience light-headedness if they arise too quickly from a lying or seated position.

Eat! And eat regularly. Good quality foods. It could be anything! Go to a doctor if you're not on a diet or anorexic.Use your common sense...

In many cases, lightheadedness upon standing indicates that blood is responding to gravity and pooling in your legs, leaving your brain with a deficiency of blood & oxygen. To test this, take your blood pressure while lying down after you have been lying down for several minutes. Then stand up and take your blood pressure again. If it has dropped substantially, you have your answer. Either way, you have useful information.
