What Causes Rise In The BP Level During Sleep?
BP runs in the area of 125 over 70 with a pulse of 65. At night, however, It runs around 200 over 110 with a pulse of 59. I have to eliminate 3 or 4 times through the night and after doing so I will take my pressure. Prostate has many miles left on it and was just checked. I am a white male, aged 73 and in excellent health otherwise. P.S. I drink 2 cups of coffee a day, one in the A.M. and one around 2pm. Most of the time its decaf. Ques. Is it normal for the blood pressure to rise this high during sleep periods? Could the lack of oxygen to the body impact this?

Hi,
Thank you for your query. I can understand your concerns.
It seems that you are having nocturnal hypertension.
Nocturnal hypertension defines a pattern of BP where BP measured during sleep is higher than that measured when the patient is awake.Normally, there is a diurnal variation in BP, with a 10% to 20% decrease in systolic BP during sleep, which is described as the normal dipping pattern.In some patients,BP rises above day time pressures rather than falling during night. These patients is also referred to as risers,or extreme non-dippers.
Obstructive sleep apnea/hypopnea syndrome (OSAHS) can also give rise to nocturnal high BP.The intermittent hypoxia, negative intrathoracic pressure variations, and arousals characteristic of apneas and hypopneas lead to increase in blood pressure at the termination of disordered breathing events evolving into sustained hypertension subsequently via chronically heightened sympathetic nervous system activity and arterial baroreceptor dysfunction.
Nocturia is common in OSAHS.
You need to undergo ABPM (Ambulatory blood pressure measurement ) as initial investigation and Polysomnography (PSG) as indicated..
