What is Lightheadedness?

Lightheadedness is a common and typically unpleasant sensation of dizziness and/or a feeling that one may faint. The sensation of lightheadedness can be short-lived, prolonged, or, rarely, recurring. In addition to dizziness, the individual may feel as though his or her head is weightless. The individual may also feel as though the room is what causes the "spinning" or moving (vertigo) associated with lightheadedness. Most causes of lightheadedness are not serious and either cure themselves quickly or are easily treated.

Keeping a sense of balance requires the brain to process a variety of information received from the eyes, the nervous system, and the inner ears. If the brain is unable to process these signals, such as messages are contradictory, or if the sensory systems are improperly functioning, an individual may experience lightheadedness or dizziness.

Questions and answers on "Lightheadedness"

Earlier today I had a sudden onset of severe abdominal cramping which also caused sweating and lightheadedness . Within about 45 minutes I had several bowel movements and I vomited once. Since then, the lightheadedness and sweating has subsised, however, the abdominal cramping is still very much there and I constantly feel like I should be in the bathroom. Along with the cramping, I am concerned about the bright red blood , which may or may not be clots, that appear in the toilet.
Hi, thanks for posting your concern in the HCM. Abdominal cramps with bloody diarrhoea and vomiting may be due to acute gastroenteritis or colitis or enterocolitis due to some infection. Less commonly, they may be manifestations of more serious conditions. Usually fresh blood in stool are due to...

I am 72 years old and have been experiencing lightheadedness in the mornings. I also have noticed numbness in my fingers and feet as well. I just had cataracts done and these symptoms have worsened. I don't feel this surgery has anything to do with it although my eyes are now so sensitive to light and my far-sightness is realy worse and I hope glasses will take care of that problem. Anyway, the lightheadedness goes away as the day progresses as does the numbness in feet and hands. Thank You.

Hi, for the past month now I've been suffering with a acid burning in my throat which I can't seem to get rid off, I've tried Gaviscon and Rennie's but still nothing also for the past week I've also been suffering with lightheadedness and dizziness and often feel like everything around me is going slow, if you could help in anyway I'd be very grateful.

Thank you for trusting HCM

Dear acid burning in the throat may be due to acid reflux with pharyngeal wall erosion.

Avoid spicy food and alcohol avoid smoking and caffeine drinks.

Eat less quantity at dinner, avoid immediate sleeping after dinner, need head end elevation during the sleep....

Welcome in H.C.M.

I have gone through your query regarding lightheadedness and dizziness, no doubt you may be having disease of internal ear and for this you have to consult your ENT doctor.

By your clinical history it appears as you may be sufferring from-

1- Miniere's disease.

My husband gets up and does not feel light headed. He takes his thyroid pill and his blood pressure medication. About two and a half months ago, he began feeling lightheaded two hours after he took the thyroid medication. He found out he had high blood pressure. He was put on blood pressure medication that he took in addition to the thyroid medication. He was told to monitor his blood pressure. His blood pressure went down to normal, but he continues to experience the lightheadedness. The lightheadedness begins around two hours after he takes the medication the first thing in the morning before eating his breakfast. The doctor changed his blood pressure medication. The lightheadedness contined. Then he switched him back to the first medication. The lightheadedness continues. He had many blood tests. His heart rate is normal. He had a brain MRI. There were no abnormalties. He was checked by his doctor a few times since this started and there don't appear to be any abnormalties. He usually only experiences the lightheadness when standing, not while sitting. He describes the lightheadedness as coming from the top of his head. It doesn't appear to curtail his ability to function. He says he thinks he doesn't get enough sleep. He is 81 years old. We don't know what the causes or cause fo this is for this problem is.
Hi and thanks for the question,
what you describe your husband is experiencing is called orthostatic hypotension. (Drop in blood pressure). A dramatic drop in the systolic blood pressure — the higher number in your blood pressure reading — may result in lightheadedness or a feeling of faintness....

Your two problems of upper back ache and persistent cough are  unrelated to each other.

After eating lunch or breakfast and when there's extreme heat when I'm outside [just for a short amount of time] I have lightheadedness, flush, weak feeling, like something is not right, I experience lots of burping. This doesn't always happen just sometimes. I'm not over weight and I'm in good health otherwise.
Try to drink a lot of water. And take Cap. Esomeprazole 40mg one before breakfast to help with symptoms of burping

I have been having lightheadedness and pressure in my head and around my ear. I also have some weakness from time to time in my arm. I am on Betahistine which helps, but I don't want to take it too much and become dependent on it.
I am on a wait list to see a neurologist, but the wait time is about four months. My doctor thinks it is a virus in my inner ear and I just have to wait it out. I am becoming anxious about my whole situation.
