Ask Dr Miriam

QI feel a bit dizzy every now and then, especially when I stand up suddenly or get out of bed. Do you think this is serous?

AThis kind of lightheadedness can be a minor problem resulting from a sudden drop in blood pressure when you stand up.

Usually it goes within a few seconds.

But if it happens frequently and you’re still feeling dizzy after three to four minutes of standing up it can be a sign of a more serious condition.

Researchers at Harvard University found people who had a prolonged drop in blood pressure after standing up had both an increased rate of brain diseases plus higher death rates.

I’m not suggesting the kind of dizziness you’re talking about falls into this category, but it’s a warning sign.

So you should go along and see your doctor and describe your symptoms.

Your doctor can check your blood pressure regularly, your heart, your arteries and your blood cholesterol.
