Is there a relationship between excessice coffee drinking and high blood pressure?

My daughter-in-law makes 5-6 pots of coffee daily.  She has high blood pressure and gets headaches.  Is she drinking too much coffee that would cause the elevation in blood pressure?  She also takes a lot of prescription pain medicine and a sleep medication.

Caffeine can increase the blood pressure, but the effect usually only lasts for a short time. Experts have yet to make a strong link between caffeine and long term high blood pressure. That being said, a lot of doctors tell patients that have high blood pressure or heart disease that they should limit their caffeine. A boost, even a temporary one, in blood pressure may not be a good idea on top of already high blood pressure. 

Besides coffee, caffeine is found in tea, energy drinks, soft drinks and even in chocolate. Some headache/pain medicines also have caffeine in them. Your daughter-in-law should let her doctor know how much coffee she drinks, as well as other sources of caffeine in her day.  Too much caffeine is often a cause of sleep problems or can make existing sleep problems even worse. 

Hope this helps!
