Q: I am a 44 years old man feeling dizziness sometimes and everything seems black for a few seconds. It happens when I stand up. Please advise.

A:The symptom of dizziness should not be taken lightly. Many conditions can cause this. To name a few important and treatable ones I would like to mention are: irregular pulse (heart rhythm disturbance), low or high blood pressure, minor vascular incidents in the brain; minor convulsions and many more including stress. The fact that you have experienced this earlier in your life as well would mean that investigations are essential for diagnosis and corrective treatment, I suggest you consult your local specialist and get investigated and treated.
