Did you call someone while the rapid heartbeat was happened no? I took metformin and my three other diabetes medications through all of my treatments. See what the oncologist says.

@lucyholly18 what did you learn from your appointment with the oncologist today? What type of chemotherapy are you on?

Yeah, its the Red Devil, because it's red! Ono. Sent me to the Emergency there at his office building to run EKG,CTwith contrast, they drew 4 times my blood to have tested, lab sent all 12 viles back !finally after 2 hrs a nurse came in a machine that could locate my good vain,then it could be read by lab! It was like I had air in my blood!!crazy! !! Having Palpitations, dizzy, tightness in right side,low blood pressure for 5 days, i was sent home to go get more testing from Primary Doc and my Indocrinologist within a few day's because something is going on! My low thyroid was hyper,and low mag.! TONIGHT i feel this chemo has done this to me! I CAN'T UNDERSTAND IF i was stage 0-1,no other spread limp node, after mass removed, cancer free,Why am I taking a Poison like Chemo?

@lucyholly18, many feel that taking chemo is their weapon against cancer, especially the invisible parts. But for everyone it is a personal choice. Sometimes the side effects of treatment are unbearable and can cause difficulties that lead to other health problems. This is very different from person to person, even if you have the same cancer type.

I think the most important thing is to have an open and frank discussion with your oncologist to find out
a) is the chemo the cause of the other health issues?
b) if yes, what are your options? Reduce dosage? Stopping chemo for a period of time or permanently? Different type of chemo?

If you choose to not have chemo, be sure to understand what this would mean for you. Does this increase the chances of cancer returning? If yes, by how much?
You see, there are many questions unanswered. I encourage to ask questions and ask again until the answers make sense to you. I often use the tactic of speaking back to my doctor what I understood. That way she can see where I may have misinterpreted something. I also like to think that I am doing them a service by speaking back their explanations in plain language. Maybe that gives them laymen's terms to use for the next patient. Who knows, right?

After 2 months of chemo now, Was sent to Emergency Rm for Heart Palpitations after my 2 nd chemo treatment, results of testing showed my thyroid had went hyper from having Hypothroidism for over 40 yrs . Got my newest lab results back,my T3 and Free levels are still very low ,my Primary Doctor had changed my Medication dose from 90mg to 60mg over a a month ago, I was told to keep taking that medication for now ! I have been so tired ,sore throat , and a really bad swallowing issue to the point of only have a liquid soft diet ! My Care team at the Chemo treatment center hasn't been concerned about my thyroid ,.matter fact they actually not even mention it ,,, shouldn't this be a major issue considering It could cause a heart attack or stroke? Anyone else that's had treatments to totally mess your thyroid levels up ?

Hi, @lucyholly18,

I'm sorry to hear about the heart palpitations, thyroid, tiredness and sore throat.

You mentioned concerns about your thyroid and your primary care doctor changing your medications.

I noted you said previously you had an endocrinologist. If you still have concerns about your thyroid, have you by chance gone to see him or her to offer an opinion?
