Possiblity of GastroCardiac syndrome?

I am willing to give this diet a shot. Thanks for the advice!

However, I have tried the keto diet and also cutting out carbs before, but there was no difference. Cutting out dairy also made no difference.

My energy crashes the least when I eat candy . I have no symptom of diabetes, but I need to eat hard candy in the morning to reduce dizziness. My energy crashes more when I eat fruits/vegetables in the morning. My energy crashes the most when I eat heavier protein.

Exercise can trigger the heart palpitations as well. Sometimes I have a thumping headache near my temples, before my heartbeat increases and I fall asleep

Hi there, I found this article online and am having very similar symptoms. Have you ever found an answer for this? I am currently on a heart monitor and feel like it’s related to GI issues. I also have pain in temples and feel like my stomach sinks. I also have a lot of sinus issues and when I blow my nose it feels like my ears block and I can’t breathe until I swallow which spikes my heart rate. Just wondering if you ever got this figured out.

I'm a 49 year old active male who's been fit my entire life. My main physical activity is cycling. about 10 years ago I began having sudden episodes of tackycardia, highblood pressure and anxiety. For no particular reason my body would go into the flight or fight response soon after a meal. I've ended up in the ER a few times after an episode since it feels like I am or about to have a heart attack. I have seen several cardiologists, nuerologists, urologists and gastrointestinal doctor. After under going many tests, they've never found the cause or problem. It wasn't until two years ago that I linked the episodes to my digestion/ eating. I've suffered from IBS for many years and have been diagnosed with gastritis. On one occurance, I went through a month where I suffered from severe anxiety and depression. Having considered myself a strong minded person, this was the first time I had ever felt this way. It was as if a switch was turned on in my body which I had no control of. During this month I had 3 occurring episodes of fight or flight responses. Doctors could not find an answer to what was causing it since my EKG were fine and all tests were normal. At the time of the episodes my heart rate would spike to 150-165 for a few seconds, My blood pressure would shoot up to 160/110 or so. The episodes lasted anywhere from 2- 10 minutes but my legs and arms felt heavy and I felt tired after each episode. There were days were I just felt so depressed I cried. I had a hard time sleeping due to anxiety. I refused to get on any anti depression or anti anxiety pills as this was not a normal feeling for me. I wanted my doctors to find out what caused this switch to turn on rather than to treat my symptoms. During this time I realized what if I wasnt suffering from IBS but rather it was the cause of my problem. I quickly cut out all sugars, flour, meat and high fat from my diet. I was strictly on fruits, veggies fish and chicken. After two weeks on this diet, the switch was turned off. No more anxiety, no more depression no more fight or flight episodes. I continued on this diet for 3 months and went from 185 to 165 lbs. I began doing some web browsing on diet and my symptoms and came across Romeheld Disease (gastric cardiac syndrome). Needless to say, I tend to get careless about my diet every now and then and but now I'm able to recognize the symptoms before they worsen. Doctors haven't diagnosed me with Gastric Cardiac Syndrome since non of the doctors here are familiar with it. I've given up on Doctors since they're main objective is not find your cure but to make sure you're not dying. Hope this helps someone.
