I started this medication last fall for an underactive thyroid. Since then I've been packing on the pounds even while watching every bite I take and excercising regularly.

Diagnosed 6 yrs ago hypothyroidism my Dr has increased my mcg to 112 my weight has gone from 115 to 170. I stopped taking levo for several months and I lost a few pounds. Decided to see an endocrinologist and see if there were other problems, all she did was check thyroid put me back on levo and I gained 5 more pounds. I hate this medication. I am going back to all natural way, again.

Has anyone had success losing weight after stopping levothyroxine? I took Synthroid and Cytomel for about 5 weeks and gained about 15 pounds. I couldn't fit into any of my clothes, particularly pants and jeans. Even my underwear didn't fit!! I'm usually a medium and XL barely fit. I also was so bloated and looked pregnant. With my doctor's approval, I've now weaned off the meds. It's only been about a week and I'm feeling better and lighter. I'm really hoping to lose this weight as quickly as it came on. Has anyone had success quitting Levo / Synthroid?

I have taken this drug for approx 3 weeks and now look pregnant! I am so glad for the people that posted their experiences and based on those experiences I am throwing out this medication!! I am a healthy eater and I never looked like this before in my life! I just came back from a clothing store where I was in the dressing room looking at myself in a mirror and wanted to cry. It must be from the meds because I am always careful about what I eat. This medication is not for me!!! Hopefully will get back down to a normal weight soon. I should have known better but the doctor kept saying it's such a low dose. BS!!

I know I'm late to the party, however I wanted to chime in because I too am looking for answers. I myself am a physical therapist assistant & my wife is a pharmacist.
I'll start in 2015, I competed as a figure NPC model, physique class. I weighed 170lbs at 5'10". My body fat pre contest was always 8%. Competition hits 4-5%. My cardio sessions in the morning, either High intensity or jogging, I aternate to keep the body guessing every morning. The sessions last 30-45 minutes. I also weight lift 6 days a week taking off on Sunday only. I have the same food every day, 1500-2000 calories. I've never been a big eater, so my dreams of bodybuilding a massive 300lbs physique are not in my cards. I spread my meals out every 3-4 hours. I only take carbs in after my weight training sessions. 50-60grams in my recovery shake depending on the intensity. I only drink water. I don't use caffeine or any drugs/alcohol. I was sending my physique pics to magazines to try and get a sponsor for two years. I only elaborate because I was in amazing condition. I rivaled any top physique athlete and won a few competitions.
I had some routine bloodwork done, and my thyroid came back hypo. Not drastically, but enough to warrant my doctor to put me on Levo. I was excited, because I thought wow I can lose even more fat and get even more lean and really make something happen on stage. Anyone ever been 5% body fat holding 170lbs of muscle knows every percent of Body fat you loose is weeks of consistency. I rocked a 30" pant and had to wear a belt because it was too big. Every muscle in my body stood out like a race horse. Vascular, hard, lean. So proud of my accomplishment...
So I started the Levo, small dose... After 1 week I noticed all I wanted to do was eat. And eat. And eat. So the first week or two I was eating horrible food, not a lot, but a doughnut once or twice a week. But I quit when he scale hit 175. 5 pounds and I freaked...
Fast forward 4 months, I finally went to the Doc, I have been flawless on my diet, it's at 2000 calories, I hit the cardio for 45 in the AM and the weights in the PM for 1.5hrs. Over 2 hours a day in the gym. Every day, Sunday's just cardio. I weighed 203lbs and had a body fat read of 17.6%...
The only thing that has changed in 4 months is Levothyroxine. I have gained 33lbs, 10% increase of body fat. My joints hurt. Running hurts daily. I would love to blame it on something else. Trust me.
My wife the pharmacist swears that goes against the purpose of levo thyroxine, and I told her big pharma butt to chill because as of today I'm done taking these pills that 1 million % caused my weight gain. I would have had to eat 5600 calories a day to accomplish that feat. My anxiety has always been way to bad to eat more than 2500 cals. 33lbs of fat? I now wear 36" pants!!! Im embarrassed. Ashamed. I am depressed. I don't leave my house unless I'm fully cloaked from head to toe. Sick to my stomach.
I tried fasting for 4 days and didn't lose an ounce. I'm resorting to all kinds of unhealthy measures and am at a loss for words. It's put a strain on my social life I stopped speaking to everyone because I'm that embarrassed. So much so I've never been a member of a "forum" and now I am because I'm at a loss. I'm 31, at 30 I was 7% body fat, 31 I'm 17%. That's not healthy.

Boy have I ever. I started Levo in September and on October 30 i weighed 214. Apt In Feb I weighed 235. I eat clean and gluten free. I exercise daily. the Levo was supposed to fix the Thyroid which is why they said I went from 189 to 214 in one year with no changes to diet or exercise. So in total in 18 months I have went from 189 to 235. With clean eating and daily exercise whole time. I go back to Endo this week and i am asking for Armour instead of Levo because I have heard many say they gained on Levo and than lost it on Armour.

I was diagnosed with Hashimotos and given levothyroxine cause my tsh was high. All other was in range. I had a pair of pants that I tried on in sept 2015 which didn't fit. I didn't want to weigh myself. In November upon request my endo changed my med to armour. I tried the pants on yesterday and got them on. Not sure how much I lost but definitely did since changing meds. I'll never go on levo again. I'll take nothing if armour isn't available.

I started taking my meds in 2005, I started with Hyper thyroids and now I am Hypo... in the mist of taking these meds I went from 145 lbs to 175 in 4 months. I am still at 175 and have been for years. I did get to 165 but gained my weight back quick. I have dieted, exercised, walked, and I can't seem to lose weight. I was never this big until I started taking these meds. I read someone else gained weight and they look like they were 6 months pregnant, that's how I look. My stomach is out there and it is uncomfortable and doesn't look right. I have decided to stop taking these meds at least for 6 months to see what happens. If I lose weight, than I know it was the meds. I hope this helped.

I'm on a very low dose of Levothyroxine and have gained 20 lbs.i have gained so much weight in my upper belly that it looks like I'm pregnant. I have always had a flat tummy until I started taking this med. I'm gonna stop for awhile and see if I lose. I feel miserable. I watch what I eat and exercise.

I am on .075MG of Levothyroxine, and have been for one year, and I am a healthy person who runs, eats healthy (MOST of the time) and is very active with a fitbit and everything. I have gained about 10+ pounds in one year, and it is steadily climbing. Before that, I was the same weight, give or take a couple pounds, for almost a decade. I am 31, so at first I thought it was just hitting that 30's wall of being harder to lose weight. I look like I am in my second trimester of being pregnant!!! It is ridiculous. None of my clothes fit. After reading this, I am thinking about stopping my medication for awhile to see what happens. When I started, my levels were over 5, but my recent lab results stated I am a 2.23 now. My question is... What happens when I stop the meds? Is it safe to do? What other things could I be supplementing with in order to keep my levels where they need to be? Thanks for all your help! :)

Hi I have experienced the same thing, I have only been on the drug for 5 months and I'm gaining weight when before I always struggled to gain any, it's also messed my period up and was stopping me getting pregnant! I stopped my meds 2 days ago after discussion with my doctor as my levels weren't too bad to begin with, but I have to be tested again in 6 months x

Not a medical person so I am speaking from my own feelings. I have been on a very low dose of levothyroxine for about 5 or 6 months. I have gained around 30 extra pounds; sluggish to no energy. I am 52 and it may be my age, heart trouble, bone disease, fibromyalgia, plantar fasciitis, my depression or just the fact that I hurt too bad to move much. I just know that I have had 3 children and my stomach was not this large, round, or hard when I was 9 months pregnant. I am beyond miserable.

In June I opted to have my thyroid taken out due to Graves disease. About a week afterward I started taking Levothyroxin. In 5 months I have gained about 80 lbs, my cholesterol has risen about 30 points (it was at 102 which is amazing), and I am always cold unless it gets to be about 75 which is comfortable. My dr has risen the dose, but I have not picked up the perscription. I know its impossible, but Im half tempted to have the dr replace my thyroid. Yes, I was overweight but I was steady, my mood was constant, and I was comfortable. This medicine is completely horrible. There has to be a better treatment out there because I simply cannot stand to continue to pack on the pounds.
Its gotten so bad that my back cant support me anymore and at being 31 I have to walk with a walker, I have to use the auto buggies at the store, and use a shower chair because after only 5 minutes of standing Im in horrible pain. I only eat once a day (I know, not good for me), and even that meal is very small. Any body have any suggestions?
