Keto cause my bloodwork to show i am hypothyroid?

[NJjoe]

Hey everyone, I am not sure where to best post this but if you have any knowledge on this please help me out. I have already read a lot of posts on the boards but have some questions. I am a 24 and have been lifting a while now. Every year around November I slack and around april get back into shape. Last May I started a keto diet (ckd) and had great success gaining muscle and getting ripped in about a month. I did it over the summer and exercised until november, where i slacked and did nothing and gained 15lbs (busy w/school and finals and just ate like crap.) After this Paddy's day I went keto again but haven't been lifting, my job was 14+ hours a day in a warehouse i was always beat. I'd carb up on the weekend, but only say 500-800 grams or so. I also know I wasn't eating maintenance caloric intake, probably a couple hundred short. Well i felt beat all the time which i said was just my job and eating and the weather, and while doing a routine lab when registering at the VA hospital in nj i was told i have 1-tested positive for hypothyroidism and 2-overactive liver function. My checkup is in 2 days and I'd love to be able to talk to the doc intelligently about this, mainly a keto-hypothyroid connection. I read that prolonged low carb diets can affect t-4 to t-3 conversion and mess with your metabolism, is this reversible/only temporary? Could the reading have come out that way because I was on day 5 of a lower calorie keto weekly cycle eating less than 20-30 carbs a day? Can anyone throw some literature my way or tell me where to find it, i've had no luck. I've never even met my doc here, this will be my 1st checkup in nj and she is gonna address both problems and in the brief phone phone conversation we had she is already talking about putting me on meds. Another question i had is if i do go on meds, will it affect my natural tendancy to produce t4/3 hormones, that is to say if my thyroid could get back on track by changing diet would the synthetic stuff hinder that? Thanks for your help guys. Reading up on hypo, I can't relate to any of the causes the medical community says are usually behind hypo, and i'm a 24 year old guy, not an older woman like i've read mainly come down with this. Anything you can tell me I will greatly appreciate, I just don't want pills thrown at me, I want to really bring up some points with backing to tell my doc. thanks.
