You kinda sound like you have diabetes not to scare you. But my brother was the same way when he got low. I'd keep checking this for a few days when you feel weird they take a bit to figure things out. Your heart rate is kinda low did they send you to a cardiologist?
See a ep this stuff happens to me to and my tilt came back positive.
Thanks so much for responding. However, I believe I was tested for diabetes in the hospital and it turned out negative. And yes a cardiologist talked with me and they had an ultrasound on my heart and monitored it for a night. They want to put a holter monitor on me and do a stress test, but my question is: for those tests you need to a) go about your normal business so they discover it and b) walk or run on a treadmill for how long, so how am I supposed to do either when I can't even stand long enough to take a shower before my heart starts pounding harder and I feel faint? I will mention my "tilt" though when I see another doctor.
Unless I overlooked you mentioned a specific HR only once, a HR of 40. This is low even for an athletic person, some have no negative side effects, other get dizzy and can even faint. A low HR coupled with a low blood pressure will increase dizziness.
I do not know how to interpret your grandmothers (happy mothers day to her and your mom) blood sugar test, seems it indicated an out-of-bounds result.
You may do better with the post on some other forum given there are no heart issues other than an unusually low HR.
I'll send a notice to the forum management asking if they have a recommendation on a better place to post your problem.
Thank you for your post! In the hospital it even went down to like 37 and all the cardiologists and nurses said it was normal and okay because of my age and how I exercise. Also my blood pressure is usually normal and not too low at all. Thank you so much for sending a notice. That is so remarkable to me that a stranger would do that. Thank you thank you thank you. I'm also visiting a doctor today, so I'm writing down all of my responses I get to give to him. Happy (belated) mother's day to you as well!
Rather than have a blood test to check for diabetes, you may be better off having a glucose tolerant test.
It does appear that the shakiness and feeling faint and dizzy is a sign of low sugar levels. This is called hypoglycaemia and you do not have to be classed as a diabetic to suffer from this. The important thing is to make sure you eat little and often so that your sugar levels do not drop so low. Also make sure that you are drinking enough water.
It is a good idea that your cardiologist is checking your heart for abnormalities.
The ear popping sounds like you have congestion and it would be worth having your ears checked out. Ear problems can make you feel sick and dizzy too. If the doctor finds that you have an infection, he will prescribe an antibiotic or ear drops. If you have a viral infection then antibiotics will not help. Your doctor can also prescribe medication for the dizzy spells if he feels that this will help. But first you need to get checked out for any bacterial or virus infections.
Hope you get sorted out soon.
