  • Oh lord I’ve put so much on. Used to be able to drop winter weight now I feel like a moose

  • #1 thing I was worried about—but so far my weight has stayed within a 5lb range (as in it flucuates within that range depending on the day)

  • You have no idea, I’m sick of working on losing or even just maintaining it!

  • Yes. I’ve gained weight and can’t keep it off.

  • The most fluctuations I’ve ever had to deal with— there is no maintaining

  • Only 3 months post op so thankfully not too much.. I’m anticipating a gain, but choosing better choices now

  • Tremendously. I’ve gained over 45 lbs in the 5 months. It’s the pits

  • I’ve lost weight when I was suppressed. Already thin, so I looked and felt very sick.

  • More or less the same weight

  • I have gained almost a stone and a half and I can’t get rid of it

  • Weirdly no. I don’t understand it because I feel like crap and my levels still aren’t right. Grateful though.

We also asked survivors their tips for losing/maintaining weight as a thyroid cancer survivor. It really came down to staying in touch with your health and perfecting your mindset.


  • Perspective is everything, don’t let this take over your life

  • Know that a lot is going to change, but it’s ok, you can handle it

  • Fatigue is real and will rob you of your energy, but find small ways to move to help your spirit

  • Be kind to yourself. I’m in the midst of it and still how to do that

  • Don’t let it take over every thought. Exercise helps a lot too but it can be hard sometimes

  • Give yourself grace. You fought cancer and all good fighters have some scars.

Don’t give up on your health

  • Keep up with bloodwork on a regular basis. Don’t let it go!

  • Don’t forget to get checked up every other month

  • Go organic, better for the hormones

  • Energy is key to working out with you need to lose or maintain your weight. B12 shots!

  • Massage therapy on the neck. There were tight spots I didn’t realize were there!

  • Try to eat as healthy as you can with lots of water and fluids too. Speak to your thyroid consultant.

  • Talk to your professionals, get connected with the thyroid cancer support groups

  • Try eating low-carb! It helped me get rid of that bloated feeling.

  • Water, water, water!

  • (If it's possible for you) try a smart watch like the AppleWatch or Fitbit! They can help you stay motivated.
