What Causes Panic Attacks And Anxiety?
Anxiety
Detailed Answer:
I am sorry to learn about your panic attacks.
I agree with you that it is important to rule out a potentially treatable medical condition before ascribing your symptoms to depression.
I noted the thyroid history you shared above but it would be worthwhile knowing the current thyroid function status by running a simple blood test. I will mention it at the end along with other tests.
There is condition called pheochromocytoma that mimics panic attacks. It is very important to rule out.
So when I see someone with anxiety/panic attacks, I order the following tests
1 Complete hemogram
2 Electrolytes
3 Calcum
4 Creatinine
5 Glucose
6 SGOT/SGPT
7 Albumin
8 TSH
9 Plasma fractionated metanephrines
The last two tests are in connection with the thyroid and adrenal respectively.
Medications may interfere with the adrenal test so first do the test and if it abnormal then confirmatory testing can be done after considering if the medications need to be stopped in consultation with your prescribing physician
