What Causes Sudden Weight Gain While On Synthroid?

Hi, I have hypothyroidism and am an insulin dependent diabetic x 42 years. I am taking Synthroid. My dose was recently increased to 50 and I suddenly gained 6 pounds (I am 5 0 ) and became constipated, bloated stomach and sleep disturbances. I stopped taking the meds and all side effects went away. I don t know what to do - I know I need to take the meds. I am looking into iodine supplements. My TSH is not going down even with the increased dosage.k

Hi,

As per your history it looks that you had gained weight because of hypothyroidism and now your dosage of medication has been increased. You also said after increased dosage the TSH level is not coming down.

Normally it should come down after the dosage is raised if it was working normally. You need to take medication as prescribed by your endocrinologist and mention which side effects you are having apart from weight gain.

Second thing you need to maintain the blood sugar level too because polyphagea will also help to gain the body weight. Also take regular light exercises too that will help in diabetic as well as weight gain issue.


Hope I have answered your query. Let me know if I can assist you further.

Regards,
