High Blood Pressure

Description An in-depth report on the causes, diagnosis, treatment, and prevention of high blood pressure. Alternative Names Hypertension Highlights Blood Pressure Measurements Blood pressure is measured in millimeters of mercury (mm Hg). The higher number indicates the systolic blood pressure, the pressure in your arteries while your heart is pumping blood. The lower number is the diastolic blood pressure, the pressure when your heart is relaxing and refilling with blood between beats. For adults: Normal blood pressure readings are below 120/80 mm Hg. High blood pressure (hypertension) is generally considered to be a blood pressure reading greater than or equal to 140 mm Hg (systolic) or greater than or equal to 90 mm Hg (diastolic). Blood pressure readings in the prehypertension category (120 -139 systolic or 80 - 89 diastolic) indicate an increased risk for developing hypertension. A blood pressure reading of 139/89 mm Hg or below should be the minimum goal for everyone. People with heart disease, peripheral artery disease, diabetes, or chronic kidney disease should strive for 130/80 or less. Blood pressure goals are being reexamined for African-Americans and for people with dia Continue reading >>

    Hello, I know this title may sound strange, but I am a medical student and so we've been doing a simulation of life as a diabetes patient as part of our learning program, and part of this requires daily measurement of blood glucose levels with an actual official glucose meter. All the equipment is standardized etc. Anyway, I am a 21 year old male and I consider myself fairly fit, definitely on the lean/skinny side but always have been, and do not have any family history of diabetes, obesity, or metabolic issues.
    I tested my blood sugar just recently, 2 hours after i had dinner, and got a reading of 6.8 mmol/L... this seems concerning to me especially as a young guy, it should not be that high right? I mean shouldn't my reading go back to normal by now? I was told the normal range was between 4-7, but its my understanding that 7 is a borderline upper limit that is suggestive of pre-diabetes. I had measured my blood glucose earlier in the day after I had a light lunch (two sandwiches and a potato salad-- not a lot for me as I have a high metabolism and burn it all off anyway), and i got a reading of 4.2 mmol/L about 20 min after eating. Considering my blood glucose barely went up that time, how did it go up by so much this time? I am wondering if the time it takes for your blood sugar to return to normal depends on how much food you ate? Because I was pretty starving when I had dinner at around 7:30, and I ate a huge amount of food (even for my standards), to the point I was basically in a food coma lol. Also I must clarify the food was very starchy (giant bowls of white rice).
    I sat down for about 2 hours to do some schoolwork and that's when i checked my blood sugar again. I am still feeling somewhat uncomfortably stuffed even now, due to the sheer volume of food that I ate, could this influence the results or is a healthy person supposed to be able to normalize their blood glucose back to baseline no matter how much food they ate? Do you guys think this is a concerning result that warrants investigation? I feel like its probably nothing but I wanted to make sure. Thanks!!

    BGL isn't from how much you ate but how many carbs you ate. A lot of white rice is a lot of carbs. Weird they didn't go over that for simulating a diabetic life for a medical student.... I mean you're also comparing a post meal reading with a fasting reading for "suggestive of pre-diabetes."

    true, i read online though that the blood sugar is supposed to return to normal after 2 hours, and if not then that may suggest pancreatic insufficiency or insulin resistance? we weren't really told the correlations between meals/blood sugar per se but would a higher carb meal take longer for even a normal person to absorb from the blood or is the insulin supposed to act in one single burst?
