Questions of a newly dx'ed hypothyroid...

1. I know one of the symptoms of hypothyroid is having cold arms and feet. Does having "cold" arms and feet literally means being cold of all the arms and feet? If so, then why do I have only the hands and feet being cold?

This can be one of the symptoms of hypothyroidism; not everyone experiences it. If you stop and think about it, the hands and feet are the farthest points from the heart. If your heart is pumping slowly because you're hypothyroid, it's harder to get the blood to them and so they may feel cold.

2. I was prescribed 25mcg of Thyrax, and I was going to take every morning. What are the side effects of this drug?

Thyrax is a brand name for the drug Levothyroxine, the most commonly prescribed medication for hypothyroidism. It really has no side effects generally. It sometimes does take time, though, to get the proper balance of hormones in your body. It may take about six weeks for you to feel the full effects of the medication. Adjustments in the dosage of medication may need to be made to get to just the right dose for you. Be sure to follow up with your doctor on this.

3. And how long do I have to take this medication to cure my hypothyroidism? Is it gonna last for life?

Hypothyroidism is nearly alway a chronic condition. The medication you're taking is not a cure for the condition, but a replacement of the hormone your body is missing because the thyroid gland isn't working right. In that way, it's somewhat like diabetes, where the body isn't producing enough insulin so supplimentation is needed.

Take your medication every morning, follow up with your doctor and you should be completely healthy and able to do everything a healthy person does.

I kept having blues before my medication.
My hands were always cold and my feet would freeze in winter.
I started feeling better the same evening I started my meds. My doctor started me right off at 100mg. In two weeks I was feeling wonderful.
I feel so great now. I'm never going to stop taking mine. :)

I had unexplained weight gain almost a year ago that i complained to my doctor about. I am very active and always lose my winter weight during the summer months working outside, cutting and hauling trees, etc., hard work. Last summer was the first time that the winter weight would not budge, I was gaining instead of losing. My doctor ordered bloodwork and said I had hypothyroid.
I started taking the 100mg synthroid and took it for 3 months and gained 5 pounds every month. I stopped taking it. I went back in and told him this and he said "synthroid will not make you gain weight, be patient" HA! Anyway, he ordered more bloodwork and the numbers were even worse so he put me on 150 mg. He told me to be patient and not get on the scale. I have been taking this higher dose for about 2 months now. I am having some dizziness and headache this past week. (No weight loss either) I am to have more bloodwork next month (after 3 months of 150mg) to see what my numbers are at that point. I don't like feeling bad. Also, I read a lot about how taking it when you go to bed is better than in the morning with all of the waiting period, etc with food. I was very sluggish when I was taking it in the morning (the first go round). I now take it at night when I get into bed. Anyone have any advice for me?
