I have been on 50 mcg of levothyroxine for 5 months and I have gained 15 pounds. My doctor tells me that it should be the opposite and that I should loose weight. Is this possible? Have any of you taking this drug has experienced the same?

I was on 50mg for about 2 weeks and noticed I had gained 10 pounds. So I stopped taking it and gained another 15lbs. now my test showed me to be 5.9 and my new doctor put me on 15mg. She said this will help me loose weight that the 50mg wasn't strong enough to help me not gain the weight.

I have gained 15 pounds on synthroid. It made me edgy and caused gastrointestinal problems.

I also was on Levothyroxine 50 for a few months and gained 10 pounds and had severe constipation. My doctor told me not diet and take Metamucil. I felt sure it was the medicine working opposite because maybe it wasn't strong enough. Either way, I stopped it and my constipation has gone away, but still have the extra weight.

I have been on levothyroxine 75mcg for 4 years and have gained 130 lbs. My docs don't seem to care. They keep telling me to go on a diet and even prescribed me phentermine. No weight loss to date.

I had a thyroid surgery four years ago, starting taking levothyroxine 80mcg and I gained 25 lbs, until I started adjusting my diet and doing excercises around a year ago, I have lost 25 lbs already and I am being able to maintain my weight, but keeping the diet and exercises.

I have been taking levothyroxine for 6 months and I continue to gain weight - my dosage is 88 mcg currently. I cant help but think it is the medication causing this -over 10lbs (approximately) in the last 6 months. I am devastated - why is this happening? I am exercsing, eating well, nothing is making a difference - the scale keeps creeping up !! and up !! I am going for bloodwork this week again.

I also have been on levothyroxine for almost a year now and continue to gain weight.I am at 88 mcg currently and this past summer I put on 10 pounds between June and September. Since I was diganosed as hypo and put on medication I have gained 30 pounds. Sometimes wonder if I was better off without the medication, at least I was 30 pounds lighter 2 years ago!

I have been on the medication for 4 months and lost 13 lbs in the first 2 months. Now the weight is slowly starting to creep back on and the doctor states that my numbers are good. I even started exercising more and my diet is no different than before I started the medication.

Sometimes when I get up in the morning my legs hurt a great deal and I walk like I am 80 years old and I am only 48. The doctor said it could be the onset of arthritis.

I exercise daily with a day off, every so often. Have been on Levothyroxix 50 MCG for 3 months and have noticed a 5lb weight gain, I feel bloated and gassy, and have a drop in energy during the mid-day. This is very depressing as I feel I have a very active healthy lifestyle. I am now looking to modify my diet and see if that helps. If I continue to see a weight gain I may ask to stop taking this. I was also Hypo, but feel like my symptoms were more Hyper, and asked my doctor if I could modify my diet rather than be on a medication. I don't like to hear that a "pill" is the answer.

Sweetie, I'm hoping that your putting mg and not mcg is a typo because thyroid medication is in micrograms (mcg) and not milligrams (mg). MAJOR difference. Also, if I were you, I would RUN, not walk, to another doctor as soon as possible. If you were on 50mcg and the doctor dropped you to 15mcg because your other dose of 50mcg wasn't strong enough, that is a HUGE HUGE red flag that your doctor has no clue how to properly treat thyroid disease. It's not uncommon to gain weight when put on thyroid meds. Reason being is that even though you were given meds, you will probably continue going further into hypo until your dosage is at the right strength. Most regular GP's and even many Endocrinologists do not know how to properly treat thyroid disease. Many base everything on labs alone instead of listening to their patients. Everyone's perfect levels are different and most drs don't realize that and go strictly by way out of range "normal ranges." Find another dr and also have them check kidney function (GFR). and complete metabolic panel (CMP) shows sodium, potassium etc. Renal problems are common in thyroid patients, especially when their drs prolonged the actual diagnosis. Sometimes the weight gain is more water weight than fat accumulation. If you're levels are right, you shouldn't gain or lose it unless you're trying. Best of luck to you.

I began taking thyroid meds 3-4 years ago (mostly Tyrosint) and I found it even harder to lose weight and my weight did creep up, despite a lot of exercise and an (at times) very low calorie diet. If I went over 1200 calls a day, I would either not lose weight or gain weight. Could not lose a pound no matter how hard I tried or how much I exercised and dieted (and I am good at both). I probably gained about 15 pounds all told. About 6 weeks ago, I decided to stop the meds and see what happened and how I felt, I did so in between appointments, as I wanted to see what my unmediated bloodworm was. I dropped 10 pounds so fast it made my head spin! Still losing and no longer gaining weight by looking at food! Not sure what is up with this. I have tried to Google and Get answers, but really have not found any, but, not sure I will take them again...
