Are You On Antidepressants When the Real Problem Is Your Thyroid Gland?

Rate This

Are you on antidepressants when the real problem is your thyroid gland? One of the symptoms of hypothyroidism can be depression, and many patients that come to me on antidepressants really need treatment for thyroid problems. So why is this often missed by laboratory testing?

Hashimoto's thyroiditis is the most common type of thyroiditis covering approximately 80% of thyroid patients. It is an autoimmune disease in which the body turns against itself, creating antibodies that attack the thyroid gland. Most people with Hashimoto's develop hypothyroidism and must take thyroid hormone replacement therapy. Inflammation of the gland will initially cause the gland to go through a phase of hyperthyroidism that will eventually damage the thyroid and lead to a state of low hormone production. In a patient with Hashimoto's, the doctor will feel a painless enlargement of the thyroid gland.

The diagnosis for Hashimoto’s disease is often missed in medicine or it’s treated incorrectly. The reason for this is because the patient may have a normal thyroid stimulating hormone (TSH) test, they can be in the normal range for free T3 and free T4, and normal range for T3 and T4. At that point their doctor may rule out thyroiditis because of the blood tests. However, it’s important to also check the TPO antibodies (thyroid peroxidase antibodies) because they are an excellent indicator of Hashimoto’s. Sometimes the TPO antibodies are extremely high even though the other tests seem to be in the normal ranges.

A couple of years ago Jane, a young woman in her mid-thirties, came in to see me complaining of abnormal weight gain within the last few months. She also had fatigue and difficulty concentrating. She had been to a couple of other doctors and her blood tests seemed fine. We ran a new test to check for TSH, free T3, free T4 and TPO antibodies. Sure enough, the other hormones were in the normal ranges but the TPO antibodies were greater than 1,000--the norm should have been less than 34! Jane was exhibiting all the symptoms of hypothyroidism but the only problem showing up in tests was the TPO antibodies.

I have had chronic ME for 23 years> My hands and feetwere freezng and my core body temperature was always low. I saw a Dr MYhill in Wales uk who tested my thyroid levels and although they were 'within the normal range' they were at the lower end of the scale and all symtoms pointed to hypothyroidism. She started me on thyroxin and within 1 week I was out of bed for the first time in 20 years. I felt warm and strong and have since made amazing progress.
Thyroxin has not cured all my symptoms, but has made a very significant change to my life.
