Gastrointestinal issue to hyperthyroidism?

[mjunebug98]

It started out as a gastrointestinal issue: nausea, fatigue, loss of appetite, diarrhea, etc.  Then all of a sudden, I couldn't sit or stand without my heart rate soaring.  Now, my BP and heart rate are high.  I'm on a beta blocker, which has helped and the Dr. said that my TSH levels are low indicating hyperthyroidism.  Last night, I woke up with my heart racing and had chills like I had the flu.   What can this be and what do i do??

i too have all the same symptoms you have,  and have had for over a year now.  no doctor can explain what i have.i have had numerous tests,  and nothing..they all want to say that i have high blood pressure and anxiety..and then throw all these pills at me that dont work,  iam too on atenanol a beta blocker,  and do you have anxiety with the rest of your symptoms...my gp ordered a test for my thyroid and it came back today as my levels being on the low side.  im now in contact with an internist to have more testing done,  so im hoping finally some awnsers,  hope this helps

Could you have been exposed to Lyme Disease?  It is one possibility.  I have had all the symptoms you describe, and I went undiagnosed for a while because I didn't have the expected joint or muscle pain, and I also tested false negative.  Most doctors aren't familiar with all the symptoms and don't realize a negative blood test does not exclude it.
