Looking for brand name for synthetic T4 that doesn't convert to t3 (liothyronine).

Looking for brand name for synthetic T4 that doesn't convert to t3 (liothyronine).

ALL T4: Converts to t3 (liothyronine) inside each cell as needed. It's supposed to do that to keep intracellular t3 (liothyronine) levels normal. Why would you want to not have T4 to t3 (liothyronine) conversion? You would then develop hypothyroidism. ...Read more

4-21-14 Thyroidectomy r/t thyroiditis, goiter. On Synthroid (thyroxine) 137 mcg- hypo s/s returning have felt great for months. Would adding Cytomel help?

4-21-14 Thyroidectomy r/t thyroiditis, goiter.  On Synthroid (thyroxine) 137 mcg- hypo s/s returning have felt great for months.  Would adding Cytomel help?

Not specific: The signs & symptoms of hypothyroidism are not specific for hypothyroidism (not a single one). Recheck your thyroid labs. If they're normal, your symptoms are due to something else. Having said that, I'm happy to do a trial of Cytomel with the Synthroid (thyroxine) in patients who want to try as long as I don't make them hyperthyroid. Some people report feeling better with comparable labs taking a little T3. ...Read more

? Gilbert's disease: It is a familial (autosomal dominant), common (2-5% of people), unconjugated hyperbilirubinemia (blood bilirubin measures 1-5mg/dl), not due to breakdown of blood. It is associated with reduced enzyme levels of udp glycuronyl transferase, that results in jaundice when patients fast or suffer an infection. It does not shorten life or raise insurance rates, but may predispose to tylenol (acetaminophen) toxicity. ...Read more

Possibly: Usually a TSH of 0.12 will not inhibit your ovulation. Although its low and your endocrinologist might decide to adjust you medications this level should not affect ovulation. ...Read more

My TSH is 9.75, T3 (liothyronine) is 2.10 and T4 is 0.73. I am taking 50 mg Thyroxine everyday. Is this enough or should i increase my dose?

Need more: TSH is still high. If you have been on same dosage for more than 6 weeks, you should talk to your primary. If dosage has been adjusted recently, you need to give it time for TSH to come down. Typically takes four to six weeks. You can also request a consult on health tap for a charge. ...Read more

Are these labs cause for concern? Calcium 8.7 L

Epithelial Cells- Many 
WBC-10-20

May be WBC: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, I trust the WBC 10-20 was in urine. If so, it should be repeated with proper urine collection of mid-stream specimen, after cleaning the external genitalia. Your doctor can advise on proper collection technique. Others are okay. ...Read more

Thyroid hormone.: We all need thyroid hormones for proper health. If you had your thyroid removed, you will have to take thyroid replacement meds for the rest of your life. If you are taking them, the level has to be monitored to be sure you are getting enough for your body to function normally. If your level is low, the medicine is increased and the level is rechecked regularly to make sure it is stays normal ...Read more

High blood pressure 160 /100 my age 29 y.Test show hi level of  triglycerides , hi level (ldl)  low level( hdl) been a year on healthy diet lose 10 kg?

Keep going : The current weight is not provided, but if not at ideal body weight, further weight will likely help. Weight and diet are two pieces of the puzzle. Environmental factors and genetics predisposition are others. Blood pressure of 160/100 is hi for a 29 year old and most would start blood pressure medications at this point. Great job on the < 20 pounds weight loss. ...Read more
