Question: hypothyroidism and not much of appetite and losing weight

 sun-ray - Thu Oct 30, 2008 5:07 pm

Hello I was diagnosed with hypothyroidism I used to be 193 and I am 5 foot 5 but I am now 162 and I keep on losing more and more weight I take synthroid 7.5 mg but I guess that was because they have been trying to help me get the right amount because my thyroid has been off. I know I have had more energy but I'm also tired alot too and am beginning to worry if its the thyroid meds or my bipolar meds that are changing my weight I'm worried I might have cancer or something or is it just the synthroid I would like any help I can with this subject I'm so confused thank you

User avatar Hello,

Since you are on thyroid hormone replacement it is essential to be checked for the thyroid hormone level and the TSH (thyroid function tests) to make sure you are receiving the proper dose.

If you are shifting from a hypothyroid state to a hyperthyroid one this will make you lose more weight and also feel fatigue. Changes in the level of your hormone may result in disturbance in the body electrolytes like K, Ca levels which would make you get tired easily.

However, if you are starting the treatment, it is expected that there will be a transition period in which you may lose weight since hypothyroidism make you more towards weight gain and fat deposition.

I would advise you to follow up with your doctor he might recheck your thyroid function tests as well as other tests accordingly. For drug interaction between your medications you better also consult your doctor.

Please keep us updated.
Best regards.

Thank you so much for the information written back. I went to the dr and they want me to get my blood taken for my thyroid disorder. They also did an x-ray on my stomach and told me I was constipated. I take meds for my bipolar and also I am hypothyroid so I guess I should've guessed that but my synthroid I thought was helping in that situation. Guess not I am going to have to watch more of what I eat I feel when it comes to that. More fiber as I have found that with hypothyroid plus being on meds for bipolar does not help. I thank you so much for writing me back. I will keep you informed when the test results come back on my thyroid disorder. I know you have alot of people that must be writing for help. I am very much relieved after the x-ray of my stomach and also for the information you gave me on what the medication synthroid can do to you when it comes to losing weight Thank you
