Rapid heartrate/high blood pressure after eating

[budgetguy]

For the past several years I have noticed that after eating food (which ranges from just a cup of milk to a full meal) that my heart rate and blood pressure increases significantly about 30 minutes after eating, and it lasts for about  one and 1/2 hours to two hours.  This occurs about 50% of the time after eating.  My heart rate goes from ~75 bpm up to 140 bmp (max todate), and the blood pressure goes from 130/80 up to 180/102 (max to date).  Note: I am borderline hypertensive and take 20mg of lisinopril a day. I have attempted to determine if there is a particular type of food, or food additive that might trigger the symptoms, and have noticed the symptoms always occur when I eat peanut butter or the snack crackers that are sold in vending machines, and will occassionally happen when I eat homemade macroni and cheese.  Other that these foods, I can find no relationships.  I can have a cup of milk one morning and get the symptoms, then have a cup the next day from the same gallon and have no symptoms.  I have had several tests in the hospital - stress test, sonogram of the heart, gastronomic tests - with no results.  Of course the tests were not conducted just after eating, so I was not exhibiting the symptoms.  Do you have any thoughts on what might be causing this?

You may be intolerant to some foods that create this high pulse rate. Search the Pulse Test by Arthur Coca which  is a pdf public domain material. Everything is free and the method consist of noting the pulse before eating, 3 times after at 30mn, 60mn and 90m. If it raises more than 16 pulses, you are intolerant to this food.
You are welcome :)

Do you stand during any of this?  Some of the symptoms sound like a form of autonomic dysfunction, called POTS.   It is where, when standing, your hear rate will go tachy after some time.  Secondly, on some forms you bp will drop, but on some forms it will stay stationary or it will elevate.  I am not saying this is it, but it may be worth looking into.

I am symptom free after taking Heathers tummy tamers since last two days. Prior to that for 3 weeks it was hell with high bp and pulse after eating even a small meal. I hope this helps. I feel for everyone who is going through this. Don't panic. Try this and hope it helps.

I just want to say, thank you even though it is now the year 2015, I found that I have eaten a lot of these thing which may have had an effect on my sudden rise in BP and rapid heartbeats out of nowhere!

Usually at dinner my BP hit 150/80. One time, I noticed my BP dropped to 130/80 after dinner. I recalled what I consumed for the whole day. The only difference is Yakult Live Lactobacillus casei. I then research its effect on blood pressure. Yakult has an effect in reduction of BP. Now I always consume Yakult.
