Constipation is more likely a symptoms of still being hypo. Do you have other symptoms of being hypo, like the 26 typical symptoms shown in this link?
Also, please post your thyroid related test results and their reference ranges shown on the lab report so that members can better assess your testing and treatment.
That severe constipation scares me so I stopped the Synthroid . I took Metamucil everyday trying to take care of this with no avail.
here is my level before treatment 1 year ago :
TSH 7.0 ( normal from 0,.4 - 4.5 )
FT4 1 ( Normal fr 0.8 - 1.8 )
and the same results also were obtained recently prior to treatment.
Yes, I do have the symptoms . Weight gain, high chlesterol ( 235 , usually between 185 - 200 ) , and high blood pressure that is difficult to control with medication , less energy and slower memory.
My PCP not sure if I have subclinical hypo which should be treated so I was refered to an endocrinologist . The endo believes I have hypo so started me with 50 micrograms of Synthroid . After 2 weeks, severe constipation began.
also , T3 uptake 35 ( range from 22 - 35 % )
Thyroid Peroxidase AB normal 26 ( normal < 35 )
Thyroglobulin AB (< 20 ( normal < 20 )
You said the the same results were obtained recently prior to treatment. Do you mean that the TSH and FT4 test results were exactly the same as before?
You are missing the most important thyroid test, which is for Free T3. FT3 largely regulates metabolism and many other body functions. Scientific studies have shown that it correlated best with hypo symptoms, while Ft4 and TSH did not correlate. In the future, you should always make sure to be tested for Free T3, along with Free T4 and TSH. You probably should go ahead and get those tests done now to better understand your current status.
Many patients find that when they start the meds, the TSH will go down and the thyroid gland will produce less natural thyroid hormone; therefore, there will be very little or no effect on test results and symptoms until the dosage is increased enough to raise the levels of FT3 and FT4. Many patients, myself included, report that symptom relief for them required Free T3 to be adjusted into the upper third of its range and Free T4 adjusted to around the middle of the range.
A good thyroid doctor will treat a hypo patient clinically by testing and adjusting Free T3 and Free T4 as necessary to relieve symptoms. symptom relief should be all important, not just test results. You can get some good insight into clinical treatment from this letter written by a good thyroid doctor for patients that he sometimes consults with from a distance. The letter is then sent to the PCP of the patient to help guide treatment.
In the letter take note of the statement. "the ultimate criterion for dose adjustment must always be the clinical response of the patient."
Excellent article . Yes, that first doctor who did the study should have included Free T3 measurement as well . Ironically, the guy is board certified endo but still could miss on this .
My question again is " can constipation be one of the side effects of Synthroid " ?
