RNY Struggling Loser with no Thyroid, thoughts?

[Lisa Coffman 0]

On 11/16/20 I had gastric bypass. I had my thyroid removed, half 25 years ago, half 10 years ago. I also had a full hysterectomy 12 yrs ago. No hormone replacement. I feel like the world's slowest loser. Tomorrow starts month 3 and I'm only down 19 lbs. However, in May '17 I weighed 343, lots of up and down in between (back up to 291 May of 20) but was down to 261 on surgery day, only 19 lbs so far since surgery, keeping calories at 800ish. I'm either freezing or sweating. 2 weeks ago after calling the endocrinologist cause I felt awful, my tsh was .09 so I was hyper, now he has me skipping one day a week of my .125 Synthroid. I am not losing like the reports I see, I'm exercising a little, treadmill & bike 10 min 2-3 times a day most days. I'm feeling frustrated because my results don't feel commensurate with my effort. I'm mortified at the thought of increasing calories. I am getting my Protein. There are so many opinions and schools of thought regarding calories. I'm just never comfortable, ice cold or sweating when I shouldn't be. Seems weird. Thoughts?

how is your Water intake? not drinking enough will slow your weight loss. also your vitamin's etc. are very important. I also have no thyroid and have been thru menopause with no hormone treatment. You are loosing 10 lb. a month which is not bad. Keep up what you are doing and give your body some time to adjust. It's been thru a lot. I also have hots and colds not sure why . You are doing GREAT just hang in there. 😃

As you lose weight a lot of hormones, etc. are released into your body that were stored in your fat which can cause issues. For me, the oestrogen that was released stopped my menopause symptoms (they came back when I reached my goal weight unfortunately) & my cholesterol levels rose very quickly (back to the level it was pre surgery now). My general liver function was off too. My GP & surgeon were concerned & I was having monthly blood tests & scans. It was my dietician who explained what was happening & that things would settle when I reached my goal which they did. I was still glad I had all the tests though - better safe than sorry.

This could be what’s happening to you too. It’s worth discussing with your endocrinologist. Hope they find a answer soon.

PS - feeling cold is very common as you lose weight. All that insulation is disappearing. I almost need to wear thermals to go grocery shopping in the middle of summer.
