Could a pituitary tumor cause temporary one sided facial drooping without paralysis? Low TSH (normal T3 (liothyronine) & T4) Low ACTH. Waiting on more test results.

Could a pituitary tumor cause temporary one sided facial drooping without paralysis? Low TSH (normal T3 (liothyronine) & T4) Low ACTH. Waiting on more test results.

Facial nerve: Any structure that affects the facial nerve along its course from the brain can cause a droop. Pituitary tumor can cause droop in eye, visual changes etc. Its anatomical and the facial nerve has several branches, temporal, zygomatic, buccal, maxillary and mandibular. Good luck. Stroke, Hemifacial spasm and bells palsy other alternative possibilities. ...Read more

My 10yr old daughter had lab work completed and the results show a high esr, low tsh, and normal t3/t4. What are possible diagnosis?

My 10yr old daughter had lab work completed and the results show a high esr, low tsh, and normal t3/t4. What are possible diagnosis?

Possibly thyroiditis: The information is incomplete, but subacute thyroiditis (sat), an inflammation of the thyroid gland can cause hyperthyroidism and high esr. People with sat have severe neck pain. With no pain sat is unlikely. A high ESR is found in many non-thyroid conditions: one can have mild hyperthyroidism and another cause for a high esr. Some people with non-thyroid illness have low TSH without being hyper. ...Read more

Unusual combination: This is a very unusual combination of results +scan. The most likely cause (if you are not taking excess thyroid hormone and have appropriate Iodine levels in your blood) is thyroiditis, Which type would need antibody assessment and exam of the gland. ...Read more

Could a low TSH (.28) & normal T3 (liothyronine) & T4 levels mean a Pituitary issue? Or is that more typical of hypothyroidism? Would high Chloride (111) effect it?

Could a low TSH (.28) & normal T3 (liothyronine) & T4 levels mean a Pituitary issue? Or is that more typical of hypothyroidism? Would high Chloride (111) effect it?

Means pituitary is: A TSH of 0.28 with normal free T4 and free T3 (liothyronine) likely means the pituitary is working properly. A TSH of 0.1-0.4 is lower than the reference range, which means about 2.5% of normal people have a TSH or 0.1-0.4. Thus, one hopes she is normal. Her endocrinologist can follow and recheck her levels in 4-6 weeks to confirm that her levels are stable (TSH not dropping lower; T4 or T3 (liothyronine) not above normal). ...Read more

Low TSH Borderline low T4 normal t3 (liothyronine). Thyroid uptake scan. Low uptake noted w\o nodules. Radiologist said HYPOTHYROIDISM?! All other possible test norm

Low TSH Borderline low T4 normal t3 (liothyronine). Thyroid uptake scan. Low uptake noted w\o nodules. Radiologist said HYPOTHYROIDISM?! All other possible test norm

Need follow-up: 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, there is inconsistency in your results. Both TSH and T4 being low does not add up. You may need to repeat the lab tests, not necessarily the scan, in about 6 months to see what direction these results are going in. ...Read more

0.024 TSH, Normal T3 (liothyronine) and T4, postive antibodies, depressed iodine uptake test. Please interpret results? Confused and not getting answers..

Thyroid tests result: If you have normal output of thyroid hormone (T3, T4) from your thyroid gland then the level of the thyroid stimulating hormone (TSH) should be low, which it is! I'm not sure why your doc ran a thyroid uptake test because you say you have normal thyroid hormone output. Ask the doc for the reason for doing a test. It should always be a good reason that you should understand. ...Read more

Hello, I have low free t4 but normal t3 tsh and all other metabolic panels. What could be causing this?

Hello, I have low free t4 but normal t3 tsh and all other metabolic panels. What could be causing this?

Thyroid: A low free T4 may be important but surely your doctor has discussed this with you.
If this has not happened but you feel OK, relax for a bit.
However, if you really are concerned please have your Primary doctor refer you to an Endocrinologist.

All should go well! Please let me know. ...Read more

What does it mean if my T3 (liothyronine) is low? TSH and T4 totals are normal.

Nothing: First how low is low.

generally T3 (liothyronine) alone does not mean anything. Specially with normal TSH, and T4

that mean your thyroid is functioning well.

check with your doctor. ...Read more

TSH normal at 1.35 T4 8 (range 10-20) T3 (liothyronine) 5.8 (range 3.2-6.0) what are reasons for low T4 levels when TSH is normal and T3 (liothyronine) high normal?

TSH normal at 1.35 T4 8 (range 10-20) T3 (liothyronine) 5.8 (range 3.2-6.0) what are reasons for low T4 levels when TSH is normal and T3 (liothyronine) high normal?

Hypothyroidism: This likely indicates secondary hypothyroidism, due to problem with your pituitary gland. Normally, if the T4 is low, the pituitary will produce more TSH to try and induce the thyroid glad to produce more T4. However, if there is a problem with the pituitary, then the TSH is either low or normal despite a low T4. Be sure to follow up with the doctor how ordered these tests. ...Read more

Can Lamotrigine (Lamictal) affect TSH levels? Also, what do low TSH mean (if T3 (liothyronine) and T4 are normal)?

Can Lamotrigine (Lamictal) affect TSH levels? Also, what do low TSH mean (if T3 (liothyronine) and T4 are normal)?

Not alot: Thyroid interaction is not common with Lamictal, however as with all medications for each individual that can be a possibility. As to your low TSH that is usually a resonse to elevated T3, (liothyronine) T4. Remember that there can be variations in your thyroid measurements from one time to another. How do you feel. Do you have thyoid symptoms: cold, tired, fatigued, skin or nail changes? ...Read more

My T3 levels have been low consistently, TSH normal, T4 on the high end of normal. Is the low T3 anything to be concerned about?

Hypothyroid and T3: If the TSH is normal, then that is strong evidence that you are normal. Pituitary TSH responds mostly to T3. If you T3 were too low, the TSH should be high. Indeed, I am not sure why T3 is being measured. There are more problems with the T3 assay than that of T4. This could just be "lab error". ...Read more

Good control!: Those figures sound swell. The normal range for both circulating thyroid hormones plus a low TSH (= Thyroid stimulating hormone) from your pituitary gland the "controller" at the base of your brain means the medication is being given in the correct dose!! Its good news! ...Read more

I've hit a weight loss plateau after 6 months of successful low carbing. I have normal T3 (liothyronine) and T4 and 0.03 tsh. Could that affect it? I take novotiral

I've hit a weight loss plateau after 6 months of successful low carbing. I have normal T3 (liothyronine) and T4 and 0.03 tsh. Could that affect it? I take novotiral

Low TSH = trouble: A TSH of 0.03 is quite low, meaning that the pituitary is sensing that the t4/t3 levels are too high for you, even if "normal". Too much thyroid hormone can lead to weight gain due to increased appetite, lower impulse control, and feeling too tired to exercise. It can also lead to loss of muscle tissue, and a decrease in metabolism. Work with your doc to get the TSH up around 1 for best results. ...Read more

What does this mean? T3 (liothyronine) free normal, TSH normal, T4 categories-t4 high, t3u low, fti high. Tsh tested again 6 months later, lower but normal. On nuvaring only

What does this mean? T3 (liothyronine) free normal, TSH normal, T4 categories-t4 high, t3u low, fti high. Tsh tested again 6 months later, lower but normal. On nuvaring only

Normal thyroid tests: Normal TSH level indicates normal thyroid function in the majority of cases. Normal free t3 (liothyronine) and normal freet4 usually support the fact. Total T4 (t4) can be high without excess thyroid when the thyroxine binding globulin (tbg), a thyroid hormone carrier, is elevated, as in pregnancy and while taking a bcp. Then t3 (liothyronine) (resin) uptake (t3 (liothyronine)u) is low and fti normal (tests now outdated should not be checked. ...Read more

More info needed: A screening test or on thyroid med? He has a normal TSH and normal free T4, so he is normal or has normal replacement results. The T-3 uptake is irrelevant. Many normal individuals have anti-thyroid antibodies. If his thyroid isn't enlarged or has no nodules, don't worry about it. If you are still concerned ask for a referral to an endocrinologist. ...Read more

Yes: Your endocrinologist is making sure that you do not have an overactive thyroid which may be caused by a lesion on the thyroid. The ultrasound will look for nodules and the iodine 123 will tell if the nodule is producing excessive hormones. ...Read more

What causes high TSH 7.0 (although normal t3, (liothyronine)t4, pth) and low cortisol (1.0)? I'm being referred to an endo. I'm worried.

No worry: In early stages of hypothyroidism TSH is high when T3 (liothyronine) T4 may still be normal. Hypothyroidism is quite common and is easily treatable with an oral medication. However, you must follow your doctor's advice for additional tests and treatments. ...Read more

Diet and exercise: You thyroid test results are normal. Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Reduce you intake of food to control weight. ...Read more

What can cause low TSH of its not a Thyroid or pituitary problem? 0.01 TSH T3 (liothyronine) and T4 free normal, graves and hasmitos negative

2 possibilities: Hi. First of all, Hashimoto's doesn't cause a suppressed TSH, and YES, your TSH is SUPPRESSED, not "low", because your free T4 and total T3 (liothyronine) are "normal". A low TSH (pituitary defect) would cause low free T4 and possibly/probably low T3 (liothyronine). The most likely is a "hot" thyroid nodule (autonomously hyper-functioning); second most likely would be a phase of subacute thyroiditis. Follow over time to tell. ...Read more
