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.
Has anyone experienced major weight gain after starting Levothyroxine?

Yes! Me too, at too rapid of a pace! I've only been on it a few months. All my pants are too small or too tight!
I can't stop this appetite!
I'm also breaking out in welts n hives. I'm not happy anymore etc.
The same thing happened to me. My gynecologist suggested that I take levothyroxine because my blood test shows that I have hypothyroidism and I wanted to get pregnant. I started gaining weight after taking levothyroxine. My weight was always stable and any occasional weight gain would go down after I cut back a little on the food.
I told my gynecologist about how levothyroxine is causing me to gain weight, have irregular periods, and even a low libido. Everything was normal before taking levothyroxine. She had me do blood work several times, but nothing ever got changed as far as medication.
I don't think levothyroxine is working the way it should. I've read in some other studies that they need to have certain combinations of thyroid medicine in order to work for some people. It's not a one size fit all.
I was on levothyroxine and gained 50 pounds. About 35 or that was in a couple months and I looked pregnant it was a weird kind of weight gain like padding all of a sudden. I have never weighed this much in my life even when I was pregnant. All the doctors I saw gp endo and naturopath who put me on this said that that wasn't possible. That was a year and a half ago. I switched to liothyronine which I was on before which made me kinda hyperthyroid.
I have not lost any of the weight . It is so embarrassing as people do not recognize me. I am not doing anything different. I don't eat very much and I eat healthy. I walk for exercise.
Has anyone else not been able to release this weight. I heard it was a reserve T3 reaction as my body was not able to convert T4 to T3. Although I am on straight T3 now and the weight is not budging. I hope this hasn't damaged my metabolism.
I am working with a fertility doc to get pregnant. After first round of blood work and testing I was prescribed levothyroxine. The doc said my thyroid was within the normal range but a touch higher than ideal.
I started the pills on the 5th of the month. By the 23rd I had gained 8 lbs. I have weighed between 123 to 128 (about a 5 lbs range) for well over a decade. Gaining 8 lbs in less than three weeks freaked me out. My jeans were so tight they were digging into me when I sat down. I stopped the medication and told doc if I'm within the normal range, then I object to the prescription. I think the doc considers me "difficult" and I'm being transferred to a different doctor. Fine by me!!! I'm so glad I stopped taking this pill when I did.
I started this medicine levothyroxine after being told I had a very very underactive thyroid. I had never even heard of any such thing before. So I been taking it for months now. Started on a low dose, then the dr took blood and said it was worse so she up the dose to 100mg now. She called me in a script without seeing her due to her knowing I needed it, but I have missed a few doses here and there. What's the deal with if u miss doses or stop taking it??? And I have also noticed I've gained a lot of wait but I don't eat great or exercise so I figured it was the reason for weight gain. But I've always ate the same and the last time I was this big is when I was pregnant 12 years ago. Also I have noticed, I was telling my husband how it's weird that the medicine was supposed to well male me feel better (right)??? Instead when I take it I feel tired all day and just wanna lay around ALL day. Grrrr I'm wondering if u stop it would it hurt me even more?
I'm 57 and never had the symptoms of a low thyroid, but after numerous blood tests my doctor put me on Levothyrocin. In a year I gained 20 pounds and my stomach is really big. I have a double chin and look horrible. I'm not the healthiest eater, but my diet hasn't changed plus I get a lot of exercise. When I look at pictures of myself from a few years ago to now, I could cry. I feel like going off the Levothyrocin to see if I lose weight. Do I need to gradually stop taking it?
I'm on levothyroxine and have been on it 18 months and I've gained 45lbs and I'm only on 50. Been to my doctors today because of my weight gain and he's doing full bloods ethic and said if my thyroid is steady he will up.my does to 75 to help me lose weight. But from reading this I'm.not so sure now. I want to lose weight not gain it...
I was diagnosed with hypothyroidism about 20 years ago by an endocrinologist. My dermatologist referred me to him because she saw that I had several symptoms, including hair loss, of hypothyroidism. I was started on synthroid. I had several bad side effects from it and asked to go on a compounded natural desiccated thyroid (NDT) medication. My dose was raised, and lowered, throughout the years. I went to a naturopath who tried me on the T3 protocol for Wilson's Syndrome, where it is supposed to clear up your hypothyroid state to where you don't need medication any longer, just natural thyroid supplements. It did not work for me. I was told it could be because I have Hashimoto's Thyroiditis, which is a very common cause for hypothyroidism.
I have been taking Nature-Throid, an NDT, which contains T4, T3, T1, and T2, which is supposed to make absorption more effective. It is similar to Armour-Thyroid, but the main difference being that Nature-Throid has hypoallergenic fillers, so to avoid problems for anyone who could have an allergic reaction to any of these medications.
In spite of all the different protocols I have been on to treat my hypothyroidism throughout the years, I continued to gain weight.
I even went to a naturopath who took me off all thyroid medication and put me on thyroid supplements alone. It still did not alleviate my problem with gaining weight.
At this point, I have come to the conclusion that, regardless of which medication regimen I am put on, or decide with my doctor or naturopath to get put on, the weight gain continues. This leads me to wonder this:
Maybe the weight gain is NOT CAUSED BY the medication, which ever one you are prescribed, or no medication if you choose to go that route, or natural supplements or natural desiccated thyroid hormones - at least in my case -
the WEIGHT GAIN continued.
I am beginning to believe that the fact that I am HYPOTHYROID is the cause of the weight gain. And once you become HYPOTHYROID, regardless of how you treat it, you are going to continue to gain weight, and not be successful in losing weight, at least in any great amounts. I was able to fluctuate 10 pounds here or there, but always gained it back, and sometimes more. I think WEIGHT GAIN is just an inevitable part of becoming a HYPOTHYROID person. It is an unforgiving disease, and I have to just accept it. The different medications might alleviate some of the suffering caused by having this condition, but I think weight gain is a permanent part of being HYPOTHYROID. :-(
Since there has been a problem recently with Nature-Throid being on back order, creating a shortage of being able to get a prescription filled for it, I tried cutting my existing pills in half to make them last longer. I just quit taking it for weeks, resulting in a puffy face and water retention among other things. I have a few Nature-Throid pills left, which I have started back on. My doctor left her practice, and I have just gotten an appt. with a new doctor. I will continue to take my remaining prescription until I see her in a few weeks.
I am not willing to put myself in the position of suffering any damage to my thyroid by stopping my medication in the meantime, without having a doctor involved in my health regimen.
Bottom line: My opinion, from my personal experience is -
hypothyroidism causes weight gain, REGARDLESS...
Same here, my weight went from 120lbs to 195 lbs in less than a year... despite excising and dieting, I do not eat junk food or fast food, only organic & healthy foods and drink lots of water , my Endo will not listen to me :( she just keeps uping my Synthroid dose ,I am now taking 125 mcg Synthroid started at 50mcg a year a go , yet I am still very tired,hair falling out in chunks and recently a craving for sweets that I am, fighting off and the weight is just piling on , Endo suggested taking 200mcg I SAID NO! I look like I am 8 months pregnant ,I have a huge belly ,my clothes do not fit anymore wearing a size 20W in pants and xxl tops ! I am beyond frustrated and mad, I am going to stop the Synthroid gradually and see what happens.
I still have ALL Hypothyroid symptoms despite being on 125mcg, something is not right, my blood tests show TSH 8.03 , she refuses to run T4 tests and I do not have the money to go to another Dr., so I have to stay where am at, where my Insurance covers it.
No matter the dosage, I am still gaining weight every day and being only 5'2 I am very short and now very wide and round that cant be very good for my heart or my body ,it is way too much weight,I am so afraid of having a massive heart attack, I am very obese due to taking Synthroid !
These boards are dangerous. Non-professionals shouldn't be advising other non-professionals how to take... or not take... or stop... any prescription medications. Opinions and personal experiences are fine, but leave the diagnosing and prescribing to the people who have spent years in medical school.
i gained a bunch of weight also..i'm getting off it now and see what happens
Yes I have. I work out almost every day and I eat ok most of the time and I've gained weight after starting this medication.
I have been taking this medicine for 20 years and I'm tired of being over weight and fighting tooth and nail to lose weight. After reading comments, I am taking myself off and see what happens.
Doc prescribed levo due to slightly high tsh. I took for a month but I had to quit it because not only did I gain 20 lbs almost instantly, I would wake up in the middle of the night in a puddle of sweat. I'm 31 male, I was 255 athletic build but could've lose a few pounds. I work out heavy weights 1-2 times a weeks, crossfit 3 times a week, and mountain bike at least once a week. I'm super active person. I jumped to 275 almost instantly. I felt like I was holding a lot of water so I dropped my carbs (and levo) below 30 and instantly dropped 10 lbs. It's been 2 weeks since stopping and I can not lose anymore weight. I've been low carb and working out. My body use to in the past respond well to low carb. Not only that I am still sweating in my sleep. I've never sweat in my sleep ever before unless I was sick. Also I'm EXHAUSTED beyond belief. I'm lucky I don't have a normal 9-5. I am good for one crossfit workout then I have to take a nap.
One day I took 3 naps! I rarely ever take naps but since I've quit levo I have to take at least one a day. I'm beyond myself, I don't know what to do. I'm at my heaviest I've ever been in a long time. I'm afraid to drink a beer or eat a single carb as I'm afraid I'll blow up even more.
I have gained a lot of weight, my Doctor put me up to a 100 mcg of Levothyroxine from 50 and all of a sudden in 3 months I gain 30 lb. and feel like I am bloated all the time. I am going to cut myself back to 50 mcg and see what happens. I asked the doctor is there anything nature I can do? He said No... Cazy... I am so tired and feeling fat...
