Hello XXXXXXX
Recieved you response to the query. Now this was a new piece of information that you develop a low
heart rate. I would agree that beta blockers should be avoided.
I don't think you have
gastritis, and I definitely don't think that you need antianxiety drugs.
I would like to know one thing, not that I know that you are from UK. Do you use a napkin (tied to neck) when you eat? Or wear some clothes that are tight towards your neck?
The reason I ask this is because I feel that you have "carotid
sinus hypersensitivity". Now what exactly is that?
Carotid sinus is a small structure in the neck in the
carotid artery in the neck. What it usually does is that it monitors the blood pressure in the body. And sends signals accordingly to the brain to regulate the blood pressure.
Now it is well known, that any pressure on the neck, often by even tight collared clothes causes it to send signals to the brain, causing the heart to slow down.
I think this is what is happening. Unfortunately there is no safe way to test this. However, now that you know what this is, I think you can think back yourself if such is the case. Any pressure on the neck- napkin, tight collar, tight shirt that presses on your neck if you bend forwards to eat- can cause this.
The best way to avoid this is to avoid tight clothes.
The other possible option that may be happening is that when you eat, the intestines take away the blood from the rest of your body. This may in turn trigger the similar response as in "carotid sinus hypersensitivity" and eventually cause the heart to slow down.
Again there is no safe way to test it. The
tilt table test is present, but only few neurophysicians attempt it.
However, the solution is again simple. After you have finished, assuming that the problem happens after meals, don't get up immediately. Relax, wiggle your toes before you get up, and have plenty of fluids. Better still, if possible, do not get up at all, and sit with your legs raised for some time, like in bed. The idea is to switch the blood from legs to the intestines.
I am sure this will help .
Would like to help you further if you have any further queries.
Best of luck.
