Can high T4 cause palpitations and irregular heartbeat?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I have been having difficulties breathing. It feels like mucus is blocking my airways. I also have this feeling that something is stuck in my throat. I did a thyroid blood test, TSH, and T3 which were normal but T4 was high. I did thyroid scan, it showed a soft cyst of 10 mm × 8 mm in my left lobe and another one in my isthmus about 6 mm. I am having a serious stomach acid, heart palpitations, irregular heartbeat, and my pause ranges between 40 to 45 each time I check it. I always feel hot, feel tired easily when doing a hard job. I would like to know if I have hyperthyroidism and for the cyst, do you think I need a surgery or is my problem something which medication can solve.

Hi,

Welcome to icliniq.com.

You are likely to be having thyroid cyst with hyperthyroidism and GERD (gastroesophageal reflux disease).

As far as thyroid problems are concerned, they are managed by medical treatment followed by surgery.

Your other problem of thick mucous and hyperacidity can be managed by a change in lifestyle, dietary habits, and medication. You have to consult your doctor for a thorough examination and necessary investigations to manage it properly.
