Does subclinical hypothyroidism make it hard to lose weight?

No: You just have to do it the old fashioned way - eat less and exercise more.

Yes: It definitely does not help weight loss. Consider treating with armour thyroid.

Absolutely: Hypothyroidism can be primary - caused by a weak thyroid gland or secondary to other hormonal problems, like a pituitary problem. Or your thyroid can become dysfunctional secondary to high insulin, estrogen or cortisol. If you have functional hypothyroidism, this problem can go undetected by routine screening tests. More extensive testing can often reveal abonormalities. This is very common.
