Why is my blood pressure high when I first wake up?

Why is my blood pressure high when I first wake up?  It starts out around 150/90 then drops fairly rapidly to around 130-140/80-85 as I stand up and move around.  After an hour or more it will eventually drop to normal 115/75.

I used to wake feeling sleepy and sluggish, but when the blood pressure is high, I wake energetic and HAVE to move around.

According to this web site from the Mayo Clinic there are several possibilities for high blood pressure in the morning. They include the following: sleep apnea, tumors of the adrenal gland, and kidney disease. I bought a blood pressure monitor at my local drugstore, and I check my blood pressure on a regular basis since I have high blood pressure and take meds. Take care and the best thing for you to do is check with your doctor to be on the safe side.

I recently went to a new doctor and noticed he was located in something called the Professional Building. I felt better right away.

PB, I found the following:

~ Blood pressure is usually highest from morning to mid-afternoon.

~ It normally dips to its lowest level during sleep. Some people (particularly postmenopausal women) have a condition called nondipper hypertension, in which blood pressure does not fall at night.

~ Upon waking, blood pressure in most people typically increases suddenly. In people with severe high blood pressure, this is the highest risk period for heart attack and stroke.

If it continues and concerns you at all, you might ask your doctor about it.

P.S. You could also cut down on salt intake (if you haven't already) and avoid stress. Oops... I guess that means we shouldn't have stuck you with Chex... Sorry!

Granny, Thanks.  It used to be the other way around, my blood pressure was too low upon waking up (70/40).  Reducing stress, salt, and especially added chemicals seemed to help.  I'm beginning to wonder if I suddenly became normal and am just not used to it.  I never understood people who could wake up and be raring to go, but then I became one.  I don't like it.  I'm hoping that it's not dangerous or unhealthy.

I'm trying to get even more exercise than my normally active lifestyle as a precaution.

Why Is Blood Sugar Highest in the Morning?

Please scroll down to read text

Many people with diabetes find that their fasting blood sugar first thing in the morning is the hardest blood sugar to control. In addition, they find that if they eat the same food for breakfast as they do for lunch or dinner they will see a much higher blood sugar number when testing after breakfast than they see at the other meals.

The reason for this is a normal alteration in hormones experienced by many people not just people with diabetes. It is called "Dawn Phenomenon." What Causes Dawn Phenomenon? The body prepares for waking up by secreting several different hormones.

First, between 4:00 and 6:30 a.m. it secretes cortisol, epinephrine, and norepinephrin. You may recognize these as the hormones involved in the "fight or flight response." In this case, their job is more benign, to give you the energy to get up and moving.

Besides giving you a burst of energy, these hormones raise blood sugar. You aren't going to be able to make any kind of energetic response if you don't have fuel, and after a long night's sleep, the fuel your body turns to to get you going is the glucose stored in the liver.

So after these stress hormones are secreted, around 5:30 a.m., plasma glucose and, in a normal person, insulin start to rise.

Though the normal person gets a rise in insulin to help cells use the morning glucose, people with diabetes don't, so instead of giving their cells a dose of morning energy, all they get is a rise in blood sugar. Growth Hormone is the Trigger for Dawn Phenomenon Researchers who have infused different hormones into experimental subjects have found that the trigger for dawn phenomenon is a nocturnal surge in growth hormone. If they block the growth hormone, blood sugars stay flat.

This may explain why some people, particularly older people, do not experience a rise in blood sugar first thing in the morning. They may no longer produce significant amounts of growth hormone.

It's possible that people who are "morning people," the ones who bound out of bed filled with energy have a stronger growth hormone response, too. Those of us, no matter what our blood sugar status, who drag out of bed half dead and need three hours to get going and are at our best later in the day, may not. Another Reason why Fasting Blood Sugars May Not Rise Another reason that may explain why some people with diabetes do not see a surge in their early morning fasting blood sugar may be that this rise is relatively slow and may be countered by what is left of their basal insulin production.

In people whose diabetes is caused primarily by a flaw in first phase insulin response--the response to the sudden sharp rise in glucose caused by a meal--the basal response may still be strong enough to keep the blood sugars controlled.

However, even people with normal or near normal blood sugars experience much higher blood sugars after eating a high carbohydrate breakfast. This was demonstrated in the CGMS study discussed HERE

The reasons for this are not yet known, but may turn out to be a result of early morning changes in the liver caused by the dawn phenomenon hormones.

Whatever the reason, you can expect to see higher blood sugars if you eat carbohydrates for breakfast than you will if you eat them later in the day, even if you are on medications. Somogyi Effect? If you read about dawn phenomenon online you will often see the "Somogyi Effect" cited as a cause. This term refers to a phenomenon also known as a "counterregulatory response." It occurs when the blood sugar drops low enough to alarm the body into thinking a dangerous hypo is occurring. When this happens, the body releases stress hormones to raise the blood sugar back to the safety zone. After this happens, the body becomes more insulin resistant for several hours afterwards.

The usual cause for this kind of low is taking too much basal insulin at night, especially if you are a Type 2 who still produces a tiny bit of your own. If you are going to go low it will usually happen between 3 AM and 4AM.

A counter-regulatory response is a release of stress hormones which raise the blood sugar. It may also cause you to wake up suddenly after a nightmare or with your heart pounding. By the time you wake up, your blood sugar has risen in response to the stress hormones. To see if a low is causing the blood sugar rebound you will have to test earlier, before the time you'd be woken up by the response.

Dr. Richard K. Bernstein casts doubt on whether the Somogyi Effect is real, blaming a strong blood sugar rebound after a low on the high doses of carbohydrates many people on insulin use to correct lows. However, I have experienced a rebound effect myself when I was taking too much basal insulin or, for that matter, too much R insulin at dinner, so I have no doubt it occurs.

I noticed that a raising my dose of dinner insulin too high always resulted in a higher, rather than lower blood sugar the next morning. The rise would be about 20 mg/dl (1.1 mmol/L). Eating 10 grams of carbs before bed eliminated the problem, and I would see a lower blood sugar the net morning. So did lowering the dinner dose of insulin. Another, Unsuspected, Cause of Morning Rebound Blood Sugars--Too Much Blood Pressure Medication Taking a bit too much blood pressure medication can also cause your blood sugar to go up first thing in the morning. That is because if your blood pressure drops too low at night, the body will also secrete stress hormones to raise the blood pressure back into the safe zone, and they have the side effect, as we've seen, of raising blood sugar.

Again, the tip-off that this is happening is that you are likely to wake up at 3 or 4 a.m. with your pulse pounding, sometimes you will think this is because of a vivid nightmare, but it is more likely that the nightmare was a response to the surge of stress hormones that raised your blood pressure.

If you measure your blood pressure after waking, the main thing you'll see is a faster pulse. The blood pressure will be back in the normal, or even slightly high zone. If you raise your medication because the blood pressure is too high first thing in the morning, you may make the situation worse!

If you are waking up with a pounding pulse in the early morning hours and see your morning blood sugar rising, too, talk to your doctor about whether your blood pressure medication needs adjustment.

Often, as you bring down your blood sugar by cutting down on your carbohydrates, your blood pressure will start dropping, too, even if you haven't lost significant amounts of weight, so an adjustment will be needed. Metformin also can lower blood pressure naturally after you have taken it for several months. How Do You Lower High Fasting Blood Sugars? Take the Load Off Your Beta Cells at Meal Time For many of us the answer is by bringing down our post-meal blood sugars. If your beta cells aren't spending four or five hours trying to bring down a very high post meal blood sugar, they may be able to secrete enough basal insulin to bring down the fasting blood sugars.

That was certainly my experience. I was unable to lower my fasting blood sugars through diet alone even when cutting carbohydrates down to less than 12 g per meal. However, when I started using using mealtime insulin or Januvia to control my post-meal blood sugars I saw a 25 mg/dl (1.4 mmol/L) drop in fasting blood sugar over several months. Try a Before-Bed Snack Some people find that they can reduce their fasting blood sugar by eating a small snack before bed. Some people use a protein snack, which can be thought of as "slow release carbohydrate" since about 60% of protein turns into carbohydrate over a seven hour period.

Others find a couple crackers or a pretzel helps. Split Basal Insulin into Two Doses Another solution if you are on a basal insulin and believe you are going low in the early morning hours may be to split your daily dose into two and take a larger dose in the morning and a smaller dose 12 hours later. Talk to your doctor about adjusting your dose if you believe you are going low. Medication If your fasting blood sugar continues to be higher than normal, even after you've lowered your carbohydrate intake, it may be a sign that you are getting past the point where you can control your blood sugar with diet and exercise alone. A swiftly rising fasting blood sugar may be a sign that your beta cells are starting to fail and the best response you can make would be to give them whatever help you can using medications. If you do this as soon as the problem emerges, you may be able to restore beta cell function. Wait to long, and those cells will be gone for good.

It is much harder to control your blood sugar when your cells are dead and your fasting blood sugar control is completely gone. So don't wait until you are waking up with blood sugars of 180 mg/dl (10 mg/dl) to consider medication. Any time you can't get near-normal fasting blood sugars with diet alone, it is time to consider medications. I'd suggest talking to your doctor about starting diabetes medications if after making changes that bring your blood sugars after meals into the normal or near normal zone you are still consistently seeing blood sugars over 110 mg/dl (6.1 mmol/L) in the morning.

That is because over the years I've seen that the people with the kind of Type 2 diabetes mainly caused by insulin resistance almost always get truly normal fasting blood sugars (mid-80s 4.7 mmol/L) as soon as they cut way back on carbohydrates. If you can't, there is something more than insulin resistance going on and well-chosen drugs can be a huge help.

My best guess is called "metabolic syndrome"  a catch-all phrase which means od and out of shape.   Two months of regular exercise eliminated the symptoms.

I have an almost identical problem, and nobody seems to be able to address the situation (clearly no one has addressed your question). The only discussion I have read alludes to BP being lowest in the morning and increasing during the day. I take no BP meds.  My BP will be up over 150 when I get up and quickly drop to 130. I've not been to the doc but am planning on getting some answers this summer, which I would gladly share with you. In the meantime if you learn anything please share.
