Sorry should have supplied more info. Been hypo for 2 years, various symptoms a big one being anxiety. All last year TSH hovered around the 2 on 75mcg/100mcg Levo on alternate days and I felt quite good. Then last couple of months some symptoms returned, short of breath, tiredness, anxiety and last test TSH 3.9 but my doctor said not to increase my medication. then started getting this sudden fatigue, the problem I have is that whenever they increase my meds I seem to get intense anxiety and have to lower them again. Just wondered if these sudden fatigue was a symptom as it's a new one to me.
It can be a number of things. It could be do to your sugar levels or thyroid. Have you been checked by your doctor?
Sounds like hypo to me but hard to comment without your history.
Post yr thyroid function levels here.
