What does sub clinical hypothyroidism mean?

What does sub clinical hypothyroidism mean?

Borderline hypo: It is when your directly measured thyroid hormone levels are normal but your tsh (pituitary hormone) is elevated suggesting very mild hypothyroidism. We dont usually have to treat this unless the patient has symptoms or the tsh level is > 10. Also if a woman is pregnant we always want the tsh to be < 2.5 so we would treat it in that case. ...Read more

Nutrient dense foods: Eat foods that are nutrient dense (like meat, fish, poultry, eggs, cheese, low starch vegatables and water) avoid foods that are not nutrient dense (like starches and sugars, including fruit) nutrient dense foods will increase your basal metabolic rate.

I have sub clinical hypothyroidism and increased my dose recently because my level for TSH was 2.6. In range. Is it possible to feel symptoms at 2.6?

I have sub clinical hypothyroidism and increased my dose recently because my level for TSH was 2.6. In range. Is it possible to feel symptoms at 2.6?

TSH of 2.6: A TSH of 2.6 is normal, therefore, i would ask you to ask your doctor to look elsewhere than your thyroid for the answer to your symptoms and get a plan to treat them. Other things cause symptoms of hypothyroidism in those patients with a normal tsh. Good luck. ...Read more

What symptoms of hypothyroidism appear in subclinical hypothyroidism ?

What symptoms of hypothyroidism appear in subclinical hypothyroidism ?

None: True subclinical hypothyroidism should have no symptoms because the free hormone levels are normal. It is only the TSH that is elevated. I think of this as the body is having to work a little harder to produce appropriate amounts of thyroid hormone (thus needing more TSH to meet those needs). ...Read more

I am suffering from  subclinical hypothyroidism and also low ferritin.....suggest me to control both by taking natural foods?

Better options: "Natural"foods are not an easy answer. What is your idea of "natural" foods? Do you consider eating thyroid gland of cows or pigs natural? There are safe and effective medications that will address the issues. Both iron and thyroid supplementation is available in pills that can be taken by mouth. There is no virtue in not taking effective medication. Please consult your doctor for the medications. ...Read more

Hypothyroidism: The proper way to treat hypothyroidism is to administer the correct amount of thyroid replacement to bring the tsh to normal range.

Why are not all doctors familiar with subclinical hypothyroidism... When you have all the symptoms but tests are in normal range. Its so common!

Not real: Symptoms of low thyroid are extremely common in the population. Most people with these symptoms have no thyroid problem. When you say that normal is not normal, it means that there are no normal people in the world. Treating a normal person with a medication (including thyroid) that is not indicated is unethical, against the hippocratic oath, and outright dangerous. ...Read more

and family history.

Test RT3: I bet you did not get reverse T3 tested. This is critical in making the diagnosis for functional hypothyroidism. Check free T3 and reverse t3. Ft3 should be in upper range and rt3 in lower range. If your ratio is off, you may need Armour Thyroid or t3, and synthroid (thyroxine) would be the wrong med for you. Make sure thyroid antibodies were tested too. ...Read more
