Problems eating carbohydrates / Increased blood pressure
I have a problem eating basic carbohydrates. Rice, oats, potatoes, etc. When I eat rice my blood pressure will elevate a bit from normal, increasing 30-50 points systolic and 10-15 points diastolic. Along with this comes a feeling of tightness and discomfort in my chest and an increase of heart rate. The feeling is bad enough that I go to ER and get checked out. EKG etc & cardiologist says there is no problem with my heart. All of this goes away 3-5 days later. Oats cause the same effect. Wheat causes symptoms of celiac disease.
Typical scenario: eat a small amount of rice and in a few hours blood pressure will elevate with increased heart rate. I will get a tightness in my chest but not angina or heart attack pain. for the duration, I will also have a feeling in my body like there is something wrong. I just do not feel good and this feeling lasts for the duration. After 12-24 hours I will have controllable loose stools during my normal poop schedule. Then 1-2 days of higher than normal BP and HR. On the last day, I will urinate a lot more frequently for a couple of hours. The next day I feel fine.
Potatoes increase BP & heart rate a little bit but not like rice & oats do. With potatoes, I get an irregular heartbeat once in a while. Maybe a couple every hour or so.
This situation has been getting worse over 6-7 years. I’ve asked several Drs along the way but the only response has been the wheat is probably celiac disease. I’ve not had a biopsy to confirm celiac. I just stopped eating wheat. Rice allergy test is negative. Blood sugar is OK. What specialty should I see to understand this better?
I am 65 yo male. 5′-8″ and 160lbs. I have heart disease. Previous stents. Meds are statins, asprin 81, losartan, and metaprolol (off and on as I have difficulty with this). My normal resting heart rate is usually around 60-65 without beta-blockers. Blood pressure is usually around 115/70 first thing in the morning. I exercise 2-3 times a week on a treadmill or elliptical and some weights, etc. I walk a lot and usually choose stairs over the elevator in my building.
I don’t feel this is a heart issue. I think it is the processing of the food triggering the heart and digestive issues. Maybe I’m short on some enzyme needed or something. I don’t have a lot of options for complex carbohydrates. What specialty should I see to understand this better? Any thoughts are appreciated. Thanks.
