winter increase in NDT?

Morning everyone. I hope you're going to have a good time this evening - whatever you're doing, and can I wish you all a happy - and healthy- new year.

I understand it is sometimes advisable to increase NDT during the winter. I've been on 2 grains since the spring and have felt 10 times better than on levo. However, I was feeling a return of symptoms so started to increase after posting on here about it. I have now increased to 2.5 grains per day.

Has anyone else done a 'winter increase' and by how much?

Thanks all xx

I think it's fine to go by how 'you feel' and a small gradual increase is o.k. As you are at 2.5 grains and in a couple of weeks you still feel you need an increase I'd only go up by 1/4 grain at one time. You can then reduce back easily by 1/4 grain.

(I am not medically qualified but believe that adjusting doses slightly is o.k.(up or down).

Dr Blanchard, usa doc and writer of some books on hypoT recommends this for all patients (T4 or NTH etc). Equally you can reduce in the summer. Depends on how you feel.

How far away from the equator do you have to be for summer and winter to be different enough to justify a change in dosing?

Not sure about distances. I am thinking southern france and up for the Northern section.

Yes, I always increase in winter, by quarter of a grain, but I'm going to try another quarter now as I'm not coping well this winter.
