Detailed Answer:

Welcome and thank you for asking on HCM!

Regarding your concern, I would explain that your symptoms could be related to thyroid hormone imbalance or synthroid.

I recommend consulting with your doctor for a physical exam, a resting ECG and some blood lab tests ( to investigate for the possible underlying causes):

- thyroid hormone levels
- complete blood count for anemia
- blood electrolytes for possible imbalance
- kidney and liver function tests.

You may need to make changes to the dose of synthroid.

Adding a betablocker could also help reduce tachycardia.

If all the above tests result normal, you should discuss with your doctor on the possibility of adding another antihypertensive drug to your therapy or increase the dose of amlodipine to 10mg daily.

Hope to have been helpful!

Feel free to ask me again whenever you need!

Kind regards,

Recent bloodwork, TSH was 4.06 near top of reference range. Did not address this problem. says it is within normal (I don't agree).
MCHC was low at 31 and RDW was high at 15.3 (out of range). This was a CBC, and TSH bloodwork. The PT with INR -10.1 - within normal is all says. PT -ref range 9.0-11.5. (that's the anemia right?) That would be ok?
I'm taking the amlodipine at 2.5 mg twice a day. When I have tried highr dosage it makes the dystolic into the 70s, but not the systolic which goes above normal. Causes balance or eye problems.
Would you suggest a heart scan to see about blockages? I know I have small arteries. Tryglerides last time were in the 80s my doctor told me. He did not seem to want to spend any time with me. I went in for blood pressure check. He was a substitute doctor.

Detailed Answer:
Hello again!

Thank you for the additional information.

I would recommend checking again your thyroid hormone levels after a month, in order to closely monitor them for possible changes.

Regarding the complete blood count changes, they seem to be indicative of anemia.

I recommend performing some other tests to investigate for the possible causes underlying anemia:

- iron plasma levels, ferritin and transferrin levels for possible iron deficiency anemia
- vitamin B12 plasma levels and folic acid plasma levels.

Considering the fact that amlodipine has such effects on your diastolic blood pressure, I would recommend taking a betablocker (like nebivolol), which do not have such influence on diastolic blood pressure.

I don't think that there is any need of heart scan, because you have no symptoms of coronary artery disease (like chest pain during physial exertion, shortness of breath, etc.).

But, you can perform a cardiac stress test, just to be sure that there is no presence of coronary artery disease.

I recommend performing regular physical activity (walking, aerobics, etc.) and avoid salt and caffeine intake, in order to help you manage better your blood pressure values.

Hope to have been helpful!

Wishing good health,

Dr. Iliri

Hi Dr. Manoranjan, I was diagnosed with hypothyroidism in February of this year. I do have lab-work from 2009 showing a spiked level of TSH (my primary physician ignored it). In June, my TSH level finally reached a normal level of 1.6. It started at 86. However, my weight still fluctuates and I am gaining again. Is it possible that my TSH level has increased again? My endocrinologist also found two small nodules in June on my thyroid that are being looked at again soon. One was less than 1 cm in size all around (he isn t concerned) and the other is about 2 cm in size all around. I am 22 years old. Is it likely that these will shrink? Thank you, Kayla
