TSH Range in the Philippines

I have a thyroid problem and it's only now that I understood that I have hyperthyroidism since my TSH is always below the normal range. My doctor is using the range of .27-4.2 as the normal range. For 2 years I was thinking that I have hypothyroidism because my TSH is always below the normal range.

My Lab

Thyroid Removed TSH Levels Went Up

My thyroid was removed due to thyroid cancer however my TSH levels were .07 before the surgery. Now, 3 months later, my TSH levels were at 9. So my Synthroid was raised to 175 and I still feel extremely tired. So I'm waiting on labwork to see if I might need a higher dosage of Synthroid. I'm scared now. I'm pushing 200 mg of Synthroid and wonder how bad that could be to my body.

Hypothyroidism with values from 3.0/0.5 up to hundreds or even thousands as described in these posts makes me think that there must be something fundamentally wrong with the measures and possibly we are talking about different illnesses. According to my doctor I am hypo with 4.0. I feel slightly better only when my THS drops below measurement level (0.01). I can't even imagine how I would feel with a value of 300.

TSH Level Over 150

Has anyone ever heard of someone's TSH levels ranging over 200? Mine were and the doctors tried to treat me with synthroid. The treatment failed miserably and I was trapped in a year-long nightmare. My levels eventually returned to normal on their own. Does anyone know what and why this happened? It was very scary and I felt like I was going losing my mind...literally.

TSH at 2.75

My osteopathic physician has placed me on a selenium supplement every other day and kelp iodine every third day. She prefers TSH levels no greater than 2.5, but does not medicate with prescritption drugs unless the patient presents with definite symptoms. I agree and prefer not to be medicated until absolutely necessary. My level has increased since December, so selenium, liquid kelp, and daily exercise are part of my daily routine now. Let's hope it actually makes a difference.

Weight loss

I got my TSH, T3 and T4 Checked up which came as .31,1.13 and 9.08 respectively. I am losing weight constantly but doctor says the thyriod is O.K. and my weight loss problem is not due to thyriod. Please give your opinion.

Thyroid Storm

FYI: if you have severe hyperthyroidism, it's lethal. Read about "thyroid storm". Do it.

Under Then Over

I had an under active thyroid for a few years so they thought. The New doctor discovered I was overdosed on thyroxine and now I have an over active thyroid. I am still not confident that I am over active. I am now on propyithiouracil 50mg and am back to constipation and feeling tired. I preferred the feeling before medicatns and wonder if I should just come of medications entirely.
—Guest Trisha


My tsh is below .1. I wonder if that is dangerous for getting pregnant.
