Intermittent Blood pressure spikes and then BP goes normal

Consider a sleep apnea study. Sleep apnea caused
variable BP ups and downs for me.

Good idea check your sleep.
Have you changed your diet. There might be something you are eating your body doesn’t like.

Going for test in October. But I wake up at 3AM every night and BP is normal.

Am seeing a naturopath tomorrow.

HI, I had this issue too. Except, I was 47, I had been sick and went home and straight to bed. That was a Wednesday afternoon, I woke up on MONDAY, in the hospital, Intubated with my arms tied to the bed and had no memory of what happened. They eventually removed the tubes and ties on my arms, and explained that I had been asleep at my house on Friday night and my BP spiked to 218/189 and I had 2 seizers, NOT a stroke before the paramedics got there. I have actually wondered if I had a small stroke because I lost strength in my right leg and right arm and my memory was suddenly terrible. The Doctor gave me BP meds and then my BP dropped so low that I had a RN at my side with a crash cart for 3 hours just incase. 10 years later, I still have BP issues and no diagnosis.

I’m being sent to an endocrinologist and I’m not even sure what they are assessing. But my cardiologist referred due to lability BP. I can go too high or too low.

In 2010, I began experiencing episodes where my blood pressure would spike really, really HIGH, then drop down to normal after several minutes, and continue to do this OVER and OVER again for an hour or so. Then my BP would go back down to normal and stay there. My blood pressure stayed within normal range the rest of the day but would spike like that again the very next day. I made an appointment with a cardiologist, who ran numerous tests on my heart, etc., which all came back normal. He determined that I was not hypertensive/did not have hypertension. He asked me if anything had changed, if I had started taking a new medication, etc. I told him that the only thing that had changed with my medications was that my Primary Care doctor had adjusted my thyroid medication (Synthroid for Hypothyroidism) and had raised the dosage from 125 to 150. And that I had started taking it the very same day that I began experiencing the BP spikes. That's when I realized that the episodes would start about 2 hours after I took the Synthroid. My cardiologist said that it was possible that it could be what was affecting my blood pressure. The next day, I went back to taking the lower dose of Synthroid and the BP spike episodes STOPPED. I did not have another episode after that. After that, I asked my PC about increasing the dose of Synthroid in smaller increments, just in case. I'm not suggesting that this could be the issue in your case. I just wanted to mention this to show that there could be something else going on in regard to other organs in your body, specifically the glands. The thyroid, adrenal, parathyroid, and other glands produce hormones that regulate various bodily functions. You might want to ask your cardiologists about that.

An endocrinologist would be checking various hormone levels. The thyroid, adrenal, parathyroid, and other glands produce hormones that regulate various bodily functions.

I will ask my doctor to refer me.
Thanks

Just had a naturopath analyse my situation. appaerently, I have intolerance
to caffeine, tomatoes, peanuts, food coloring, uncooked vegetables, food
preservatives. Adrenal overloaded and strain on liver.
Can only take best quality vitamins. Most of them have additives that spike
my BP.
Taking Marshmallow root tea, Ashwagandha and expensive vitamin B12. Blood
pressure normal since cutting out all processed foods. I buy from local
farms now.
