Do these results indicate hyperthyrodism?

So i went to get some lab work done as a yearly check up
             Range

Ft3   7.98   3.8 -8.3 pmol/L
Ft4   28.13  9 - 20 pmol/L
Tsh   1.77   0.3- 5 pmol/L

Yes, those results do indicate the likelihood of hyperthyroidism.  The next thing you need to know is the likely cause.  Two possibilities that need to be checked out are Graves' Disease and nodules on your thyroid gland that leak hormone faster than normal and result in high levels of Free T4 and Free T3.  Although Graves'  usually shows a low TSH, I would still test for Graves', with the Thyroid Stimulating Immunoglobulin test (TSI).  If that is negative, then an ultrasound of the thyroid gland would show the condition of the gland, and if there are nodules.  

What kind of symptoms, if any, are you having?

Your TSH isn't as low as we'd expect with thyroid levels that high, but, typically, those are what we might consider hyper thyroid levels.  That does depend on whether or not you have symptoms of being hyper.

It would be helpful if you could let us know what, if any, symptoms you might have.

Also, please tell us whether or not you're currently taking any replacement thyroid hormone medication.  If so, what medication(s)/dosage(s) and how long have you been on it/them?

I am on no medication, I believe I had my thyroid levels checked a few years ago, they came back normal, the only I reason I decided to go check was because I wasn't gaining weight and muscle pain and mild insomnia, I am going to the doctors tomorrow but is Hyperthyroidism life threatning?
And could it be caused by high iodine intake? I don't really show symptoms of graves disease like high heart rate or large thyroid and none of my family have it
Hyperthyroidism "can" life-threatening, if one goes into a thyroid storm, which requires emergency care.  Left untreated, it can affect the heart, eyes (Thyroid Eye Disease), etc. Most people feel too bad to leave it untreated.

High iodine can cause, either hyper or hypothyroidism.

As gimel mentioned, hyperthyroidism can be caused by Graves Disease, which is an autoimmune condition in which the body produces too much thyroid hormones.  It can also be caused by nodules that produce hormones independently of the thyroid.  A third cause is Hashimoto's Thyroiditis.  While Hashimoto's is, typically, associated with hypothyroidism, many people go through periods of hyper, in which the thyroid "dumps" hormones as the thyroid sputters prior to stopping working.  These periods can alternate with periods of hypo or even normal.  I believe I alternated between hyper, hypo and normal for, at least 10 yrs before becoming permanently hypo.

Along with antibodies to test for Graves (Thyroid Stimulating Immunoglobulin (TSI), you should ask for the antibody tests to rule out Hashimoto's.  Those are Thyroid Peroxidase Antibodies (TPOab) and Thyroglobulin Antibodies (TgAb).

The most common symptoms of hyperthyroidism are weight loss/inability to gain, diarrhea, hand tremors, rapid heart rate, heart palpitations, irritability, mood swings, nervousness/high energy, fatigue (I know that sounds contradictive to have high energy and fatigue at the same time, they do), insomnia, etc. Not everyone has all the same symptoms.

Autoimmune conditions, often run in families, but not always and family members don't always get the same autoimmune conditions... for instance, I have Hashimoto's and Pernicious Anemia, my son has Type I Diabetes and my daughter has Lupus.  They're all autoimmune, we just didn't all get the same condition.

Be sure to let us know how your doctor's appointment goes tomorrow.
Thank you so much for replying, is it possible that I might have no throid related disease because I have done some research and it says
"Euthyroid hyperthyroxinemia is defined as a condition in which the serum total thyroxine (T4) and triiodothyronine (T3) concentrations are increased, but the thyroid-stimulating hormone (TSH) concentration is normal and there are no clinical signs or symptoms of thyroid dysfunction. These changes may be transient or persistent. [1]

In the past, euthyroid hyperthyroxinemia was a diagnostic challenge and many patients were inappropriately treated for thyroid disease. Today, serum TSH is a screening test for thyroid function, and a normal TSH value should not be followed by measurement of total T4. In these circumstances, euthyroid hyperthyroxinemia frequently remains undetected with no harm to the patients."
Could this be what I have? And tomorrow my appointment is with a gp, would it be better to see a specialist


Anything is possible, but I'd never just stop with a measurement of TSH, though it's considered the "gold standard" in thyroid testing.  TSH is a pituitary hormone, not a thyroid hormone. It's a diagnostic tool and can help find, both, pituitary/hypothalamus and thyroid issues.  Because your TSH isn't as low as we might expect, doesn't mean you don't have a thyroid issue.

It's also possible that your thyroid is dumping hormones and your pituitary gland (or hypothalamus) has a problem and doesn't realize that there's a problem...

You need to have a thyroid ultrasound done to see if you have nodules that could be producing hormone independently and you also need to have the antibody tests done to find out why your hormone levels are high.  

You do need to know what's going on, even if you don't have symptoms.  High thyroid hormone levels can cause other problems in your body over time, such as with the heart, eyes, reproductive system, bones, etc.

Would you mind telling me how old you are?
I am 20 years old, my doctor today (gp) told me to go see a specialist tomorrow which is what I am planning on doing. Have you ever had higher ft4 levels?
Would it be a good idea to start a low iodine diet
I have had high FT4 levels, as well as slightly high FT3, but I also take replacement thyroid medication.  

When I think I was going through hyper periods prior to diagnosis, no one ever tested my levels, so I don't know if they were high or not.  I did have quite  a few symptoms of being hyper, at times, though.

Did your pcp give any indication of what s/he thought might be the problem?

I assume the "specialist" you're going to see tomorrow is an endocrinologist?  

I think I'd just see what they say before I made any changes, since it doesn't seem like it's taking you long to get in to see doctors.  Often it takes months to get an appointment with a specialist in some areas.
My doctor decided to retest my thyroid, these were me results

Tsh   1.89    0.25-5
Ft3   5.02    2.6-6.8
Ft4   20.23   10-22

Your Free T4 is still plenty high, but at least the results are all back into the normal ranges... how are you feeling?  

You still need to have antibody testing and an ultrasound to find out why your levels spiked previously and whether it's likely to happen again.
