My Weight Battle with Methimazole and My “Hot” Thyroid Nodule”

In January 2019, I was notified that it was time for my annual free Medicare check-up which included a blood work-up. Dr. Rebecca Talley, my General Practitioner, called me with the results. “I’m referring you to your endocrinologist. You have thyroid nodules.”

The thyroid sits just below our voice box near the base of the neck. Two hormones made by the thyroid gland help regulate our metabolism — the chemical processes in your body that break down what you eat to make energy. They can affect how fast your heart beats, how deep you breathe, and whether you gain or lose weight. They can also help control your body temperature, cholesterol levels, and women’s menstrual cycles.

As a follow up to the blood lab, Dr. James Millen had an ultrasound test done on my thyroid and found several nodules sitting in my thyroid. One was “hot” producing too much T-3 hormone. He put me on 10 mg of methimazole, to calm it down, and the fun began

I had lost all the way down to 220 pounds from 236 by heating healthy and walking two miles five to six times weekly. My goal was and is 200.

Ha! Forget losing weight. Methimazole caused my weight to go up. When I noticed the unwanted weight gain, I Googled the drug. Alas, I found out that patients on Methimazole gain weight, a lot of weight even as much as 30 pounds! Ouch!

My weight ballooned up to 230 seemingly overnight. I determined not to gain more.

To complicate matters, I am 68 years old and a T-1 insulin dependent diabetic. I use a Medtronic 530g insulin pump to control my blood sugar. That and walking and eating healthy keeps my A1c around 7. Dr. Millen wants it around 5 which I find near impossible.

(The hemoglobin A1c test tells you your average level of blood sugar over the past 2 to 3 months. At 7, that’s an average blood glucose or blood sugar of 150. At 5, that’s an average of 97).

So, back to my 230 pounds issue. I’m doing my best to manage my diabetes and lose weight at the same time.

I did get it down to a remarkable 228 which I was very proud of. But, it’s hard to sustain it, and I can’t seem to lose any more. It fluctuates from 228 to 230.

This morning’s (September 9) weigh-in is 230.4. That’s an increase of 1.3 pounds from yesterday’s 228.2 😩. But at least I can account for it.

Last night, we ate at Wild Wings Cafe with my brother. I was determined to order a healthy salad and got THE BIG BUFFALO FRIED CHICKEN SALAD. I ordered fried onion rings for an “appetizer” and my brother added tater tots.

Fried chicken salad + fried onion rings + tater tots = 1.3 lb gain.

Oh well, back to the drawing board. It’ll probably take me two weeks to lose what I gained in 30 minutes. But, it sure was fun gaining it!
