Hello, I am a 17 year old male.
I have rapidly gained more than 40 pounds over the last one year, even though my appetite has roughly been the same. So, I decided to get my thyroid profile checked, also because a lot of people have told me that my thyroid gland (basically the neck) looks weird. I do not see any reason behind this sudden weight gain besides abnormal thyroid. I have tried losing by working out and going on diets, but nothing works. I constantly feel tired and exhausted. My face looks terribly swollen. Also, I have been a vegetarian for 6 years.
The weight makes me feel really embarrassed and helpless.

Height - 5 feet 10 inches
Initial weight - 110 lbs
Current weight - 160 lbs

Here are my results;

Thyroid Profile, Free, Serum (CMIA)
(Test done on an empty stomach at 9 am in the morning)

T3, Free; FT3 - 3.71 pg/mL
T4, Free; FT4 - 1.23 ng/dL
TSH, Ultrasensitive - 2.260 uIU/mL

Can anyone help me interpret my results?
Thank you in advance.

All the results look within normal range to me. What did the doctor tell you?

The thyroid is an endocrine gland, generally of butterfly-shaped placed in the lower front of the neck. Its function is to create thyroid hormones which help body to use energy and keep all organs working normally. It is essential for normal body metabolism. Thyroid [diagnostics][1] include blood tests, imaging tests, biopsies and other tests.

The most common diagnosing method is blood testing which measures the capability of thyroid hormones level. It defines whether hormone production is overactive, underactive or normal. It measures TSH (thyroid-stimulating hormone) in your bloodstream whose level should remain in the range from 0.3 to 3.0. However, for more details, I am placing one link i.e. http://thyroid.about.com/od/gettestedanddiagnosed/a/bloodtests.htm that helps in knowing your test result accurately.
