Dehydration is double edged sword as far a blood pressure is concerned. It can cause High blood pressure as well as low pressure depending on over all health and age of the person. High blood pressure is linked to ageing and the chronic dehydration leads to accelerate aging process. This makes a direct link between both conditions. So it can easily be derived that it is not really the ageing but the dehydration that leads to high blood pressure. 

This also means that all the other coronary diseases like stroke, multiple sclerosis and heart and many kidney diseases are all also caused indirectly by dehydration. 

With chronic high blood pressure the blood vessels can become weak with poor tones. These weak vessels will ultimately become saggy which can not constrict properly causing low blood pressure.

It is irony that dehydration causes problems on both ends of the blood pressure spectrum. This behavior has a significant impact on the kind of medication you take to reduce blood pressure.

Diuretics taken to reduce blood pressure may cause dehydration and you get into a vicious cycle. Therefore the best diuretic you should use is water. It will not let you dehydrate as well as act as diuretic.

The relationship between water and salt absorption by the body is very complex and confliction researches make it even more confusing. Therefore sticking to natural way of managing blood pressure and keep it normal is far better than taking medication.

Drink a lot of water daily to ensure that you remain properly hydrated through out the day. Over a long period this habit will bring you blood pressure to normal levels.

Dehydration cause many other medical conditions so avoid chronic dehydration.
