Yes your TSH is high and your T3 and T4 low but it would be helpful to give the normal ranges in brackets.
Were you given any diagnosis or did you only receive test results?
Is there any reason for your weight loss?
Have you had any difficulty with eating that has caused you to eat less?
Any problem with lumpiness in throat? Swallowing problems? Tenderness?
Could you ask your Doctor to arrange for you to have an Ultrasound scan of your Thyroid gland?
You will also need Thyroid Antibodies blood tests.
If you then have diagnosis of Hypothyroidism your Doctor should treat you with low dose Levothyroxine to begin with and retest in 6 - 8 weeks and increase dose gradually.
In my experience people with Hypothyroidism have unexplained weight gain. My Hypothyroidism was caused by Hashimoto's Autoimmune Thyroiditis.
You say you have been in good health apart from weight loss. Have you experienced any symptoms at all?
Your weight loss averages out at less than 1kg per month. This would be ideal for someone on a healthy reducing diet. Have you been eating your normal full diet?
Hope you find this helpful. Have also sent you a pm.
