Thanks for the additional information. Well, it sounds like you need a comprehensive physical examination and possibly some lab studies. It is possible that you are having low blood pressure and nausea from dehydration, over active vagus nerve, anemia (or if you are sexually active, pregnancy). The treatment for these different causes vary wildly, so it is important to get to the root of the cause. In the meantime, keep well hydrated. If you have any fainting, black or bloody stools or abdominal pain, or other concerning symptoms, you need to go to the ER right away.

I dont have anemia and I can't be pregnaunt. My own gp has done does tests including kidney function and liver. I am sorry but I don't find that answer useful.

Well, another possibility is an over active vagus nerve. In this sense, when you are standing up, your blood pressure is not being maintained properly. This is called orthostatic hypotension. Generally this is seen in older people and worsened with medication, but it has been reported in younger women as well. The physician to see is a neurologist. Treatment depends on the cause.You will need to have more tests.

Can this still be the case when everytime my gp takes my blood pressure, its ok

Expert:  Dr. Cameron replied 7 years ago.

You need to have your blood pressure taken sitting/lying and standing. I doubt your GP did that.
