Hi,thanks for query.Thyroid disorder
can be easily diagnosed by blood test
.When it is negative in most of cases the it is excluded.In case of normal thyroid with above problem you need to look for other hormonal
disorder.Please also check your blood sugar,blood counts and ultrasound
abdomen to look for a cause.I hope you had done all the three tests of thyroid.If not please go for all the three test,not one only.bye.
