Question: Hi Dr Sanghvi

You may remember a few days ago I contacted you recently about my raised ALT of 74 with other LFT normal and raised TSH at 6.4 with normal T3 and T4. You very kindly reassured me to have LFT repeated and to have thyroid antibodies.

I have had the LFTS repeated and ALT is now 47. TFTs taken at same time (2 days ago) now show TSH at 13 with normal T3 and T4.

Please could you advise on latest results.

Thanks XXXX

Brief Answer:
You have hypothyroidism.

Detailed Answer:
Hi, dear
I have gone through your question. I can understand your concern.

Your ALT comes down to normal so nothing to worry about that.

Your TSH level is increased further with normal T3 and T4.

You have sub clinical hypothyroidism.

Most common cause of hypothyroidism is Hashimotos thyroiditis.
However transient rise in TSH may occur sometimes without any disease.

But you should investigate for thyroiditis once for early detection.
You should go for TPO antibody test and free T4 level.

It will give you exact idea. Then you should take further treatment accordingly.

Hope I have answered your question. If you a have any doubts then feel free to ask me. I will be happy to answer. Thanks for using health care magic. Wish you a very good health

Thanks. Yes good news re ALT. I asked my GP for thyroid antibodies and he said they were not necessary and to start levothyroxine immediately. I have asked for the test regardless and should have results in next day or so. I shall wait until results of antibodies before starting medication and let you know results? Thanks

Brief Answer:
Levothyroxin is needed.

Detailed Answer:
Hi, dear
I have gone through your question. I can understand your concern.
Yes you have hypothyroidism so levothyroxin is needed but still you should go for antibody test. Because if it is hashimotos thyroiditis then other treatment is also required. Please give me follow up with your reports. You can start levothyroxin without waiting for reports.

Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health.

Brief Answer:
Over dosage can leads to arrhythmia.

Detailed Answer:
Hi, dear
I have gone though your question. I can understand your concern.

You should start with minimal dosage because high dosages can increase the sympathetic activity and coronary events or arrhythmia can precipitated.
So start with minimal required dosage. It will avoid development of hypothyroid symptoms.

Generally life long treatment is needed. But once dosage is set, semiannual assessment is required.

Thanks. Will start with low dose and see how it goes. Will let you know thyroid antibody results. Just to be sure are there any further tests I should have done? Was kind of linking the paroxysmal AF with the suddenly raised ALT (although normal on last test) and now TSH. Was worried there was done other explanation such as carcinoma, sarcoidosis etc etc

Thanks

Brief Answer:
Thyroid antibodies test and free T4 level are required.

Detailed Answer:
Hi, dear
I have gone through your question. i can understand your concern.
Thyroid antibodies test and free T4 level are required. No other test required at this stage. Don't worry much about that. it is not related with your paroxysmal AF.

Give me fallow up with test results. Start levothyroxin according to your doctor's advice because it is prescription based medicine.

Hi XXXXXXX I have been back to the medical centre and thyroid antibodies are all completely normal. They have advised to hold off on the levothyroxine due to antibody test and being asymptomatic and retest in 6 months and have thyroid ultrasound in meantime too. Thanks XXXX

Brief Answer:
You should retest after 3 months.

Detailed Answer:
Hi, dear
I have gone through your question. I can understand your concern.
It is good news that your antibody test is negative.

So now you have subclinical hypothyroidism with only with high TSH and normal t3 and t4.

Whether to start with levothyroxin or not is controversial in asymptomatic cases. Some physician start the treatment with TSH level more than 10. However transiant rise in TSH is one issues.

Many physician goes with wait and watch approach.

If your physician says that ypu should hold off with levothyroxin then yhere is no harm in that.

But in my opinion you should not wait for 6 months. Just repeat your TSH after 3 months. If it comes to normal then its ok. And if it increase further after 3 months then you should start treatment irrespective of symptoms to avoid symptomatic hypothyroidism.

Go for ultrasound neck and if youphave any nodule then fine needle aspiration cytology is also helpful.

Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health.

I have symptoms of what appears to be hypothyroidism (hair loss, weight loss, heart palpitations and spikes in blood pressure, shaking, dizziness, thyroid nodules, a now-visible lump, etc. These symptoms are now getting worse. I have had several tests: thyroid sono showed nodules, nodules are palpable, and iodine uptake moderately high at both testing times. However, my blood tests were relatively normal and do not seem to match up with my symptoms and the other tests. My cortisol level was slightly elevated at 21.1 ug/dl. Thyroid Stimulating Immunoglobulin was 22, Free T4 was 1.49, Free Triiodothyronine was 3.7, and TSH was 3.84. The endocrinologist was truly stumped; she consulted with others in the practiced and they were stumped as well. She told me that they had only seen these sorts of results once or twice in several years. She said it could be thyroiditis, or thyrotoxicosis(?), but never gave me any sort of diagnosis. She prescribed propranolol for the palpitations, and that was about it. She released me back to my family doctor. Now my thyroid is much more swollen, and is visible. It has become painful, especially when swallowing or turning my head. My hair loss is getting worse, and the weight loss is becoming alarming to my family and friends. Have you ever heard of these sorts of results? And do you have any idea how I should proceed?

I have had Hashimoto s Thyroiditis for 23 years and have been on El Troxin for that time. About 1 month ago, we switched my treatment to dessicated thyroid, starting at 1/4 grain 2X a day and raising it after 10 days to 1/2 grain 2 x a day.. My throat had started to feel sore so we raised it to the 1 grain daily. On taht day, I had a wonderful feeling of energy and positiveness that I had not experienced for 20 years. About 3 days later the sore throat came back with a vengeance and my neck swelled up - not in the thyroid area but on the side of the neck and as well the lymph nodes under the jawline. My doctor did not raise the dosage again because he did not feel that the sore throat and swelling was related. The pain and swelling got so bad that I had to go back to the El Troxin. The swelling went down a for a few days but now the sore throat is perisitent and the swelling/innflammation has conme back. I have just been searching the internet and see that the sore throat and swelling can be quite related to Hashimoto s. But I did not have these symptoms before switching to the dessicated thyroid. I would like to try switching back and raising the dosage sooner. This is what they suggest in the book Stop The Thyroid madness . Could I have awakened the thyroid by switching medications thereby causing this symptom? I do have symptoms of hypothyroidism that are becoming more apparent What would you suggest? I am 58 years old and have an extreme allergy to electromagnetic fields which has been recently diagnosed. I left my career as a real estate agent in a large city and moved to a small town away as much as possible from EMF s. I weigh 128 lbs.

i was diagnosised with thyroiditis 3 years ago. I have been on synthroid for almost 3 years. But before that, I had an infection and was placed on oral doxycycline. we have a pool and i was out in the pool all weekend with sunscreen on. Then my daughter and i went to the beach, stayed about 2 hours, walking around and sitting on the beach. no problems. then on our way home, i started to get sick, nausa and diarrhea. by the end of the night, i was having chills and teeth chattering. thought it was from dehydration, but i was hydrated through out the day. ever since then, every time i am in the sun and get a slight redness, i go through the same thing again. it has been going on for 3 1/2 years. no one seems to know what is the problem. i have been tested for lupus, and so far it has come back negagtive. I also had a ct scan to rule out carsonoid syndrom. That was negative also. I am going to be tested again in december for lupus. not sure if anyone else has anything similar to this. my doctor doesn t know where to go from here, but she keeps trying to find something by reading.... so for now, i mainly hibernate in the house on hot days. boo boo, cuz i like the sun! also something i forgot, I am on hormone replacement and it has helped with alot of the red face with being in the heat. so who knows what is the problem... any suggestions?
