Why do I always feel faint?Neurology Sport Medicine Health & Fitness
I'm 17 years old, and ever since last year I've been constantly feeling like fainting (but have never actually fainted). I feel like it's gotten worse of late. I don't have any pre-existing medical history. I was low on B12, folic acid and iron, but I've been on supplements so it should have corrected by now. 2 blood tests have ruled out any thyroid imbalance. I'm also a healthy weight, although I'm not exactly fit. Is there any way to explain this, and should I be worried? Thank you!
If you browse through some of the questions here you may find that there are many in relation to fainting or "near-fainting":
This shows how common this symptom is especially amongst the teenage age group.
Fainting has many causes though the vast majority are benign. The most likely cause is vaso-vagal, which usually occurs in young adults and has other features such as vomiting, sweating and greying of vision etc.
However it is important that you have a thorough history and clinical examination from a physician before we come to the conclusion. Some basic clinical tests may also be required. In some cases tests such as echo, Holter and tilt-table testing are done.
Treatment depends on the cause but there are measures you can take to avoid the episodes. If the episodes are fairly frequent and disrupting your quality of life the physician may recommend some medication, but again, in the vast majority, it is not required.
Hope this is of help.
