Is it normal to experience weird blood sugar spikes while taking cytomel (liothyronine)?

Is it normal to experience weird blood sugar spikes while taking cytomel (liothyronine)?

No: I hardly remember a single case where thyroxine (or Cytomel (liothyronine) for that matter) is having any impact on blood sugar levels. If the reason in taking Cytomel (liothyronine) is autoimmune thyroiditis, then theoretically there is a risk of developing auto inflammation in the pancreas (about 10-15% of type i diabetics will develop autoimmune thyroiditis). Please discuss this with your endocrinologist. ...Read more

Blood Sugar (Definition)

The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more

What should my blood glucose/ blood sugar be at?

What should my blood glucose/ blood sugar be at?

70-99mg/dl fasting: Normal blood sugars are between 70-100mg/dl when you are in a fasting state (at least 8hrs). Diabetes is present when the number hits 126mg/dl in the fasting state. When the sugars fall in between these ranges (100-125), this would be considered impaired fasting glucose or pre-diabetes (borderline diabetes). ...Read more

Will 4 grams of sugar affect fasting blood glucose?

Do you have diabetes: If you have diabetes the more sugar you take the higher your blood sugar is likely to be. If you don't have diabetes it is likely that 4 grams of sugar won't affect your diabetes. Why are you taking 4 grams of sugar? Are you really weighing it? ...Read more

I smoke rarely, every few days i would have one. Would i be able to keep a good blood glucose/sugar level if i just have just one cigarette?

Your blood: Sugar depends upon thousands of things, most of which you cannot control. You can, however, control diet, exercise, risk factors, medication, monitoring, glucose control etc. Smoking is one of those thing you an also control. It's not up to me to tell you how much you can get away with before you have trouble, because it's impossible to state with certainty. Your choice. I can't give permission. ...Read more

What is making my vision blur? Its worse when i eat sugar or blood glucose goes below 5.0mmol but is sometimes blurred when glucose level is good.Idea

Fluctuating glucose: Patients with fluctuating blood sugar levels often have fluctuations in vision. It could be simply that, something like latent hyperopia and need for glasses, or something more serious. You need a good eye exam to diagnose. Diabetics need to be seen annually at the least. ...Read more

I'm on Levothyroxine and Cytomel (liothyronine) for T3 and T4 and my blood work came back TSH w/Reflex to FT4 is 0.01 L and T4, FREE is 0.6 L. What does this mean?

I'm on Levothyroxine and Cytomel (liothyronine) for T3 and T4 and my blood work came back TSH w/Reflex to FT4 is 0.01 L and T4, FREE is 0.6 L.  What does this mean?

Several things: Hi. Without seeing your thyroid function over time, I'd say the fact that you have a goiter & 2 cm nodule (same thing, or different?) AND taking T4 AND T3 (liothyronine), (liothyronine) you may be over-treated with T3 (liothyronine) so that your TSH is suppressed and that causes low free T4, which is not made up for by the levothyroxine you're taking. I suggest you talk with your doctor, who won't have to guess like we do! Good luck! ...Read more

If T3 (liothyronine) is converted from T4 inside the cell, how can they measure the free T3 (liothyronine) in the blood test?

If T3 (liothyronine) is converted from T4 inside the cell, how can they measure the free T3 (liothyronine) in the blood test?

Similar to free T4: Both T4 and t3 (liothyronine) circulate in bound and free forms after formation in the thyroid (t4) and peripheral (t3 (liothyronine)) cells. The free t3 (liothyronine) can be measured but the results are much lower and less meaningful than free t4. ...Read more

Not sure why a t3 (liothyronine)...: was tested--definitely not a standard screening test. if your tsh is normal there's nothing to worry about. you should speak to your doctor who ordered the test to review the additional laboratory data and answer your questions. ...Read more

My reverse t3, (liothyronine) serum is 35ng/dl. It seems really high for my age (35/m), with normal blood pressure.  Any suggestions on how to lower rt3?

Depends: This depends on the cause of the high RT3. Common causes are low iron, low B12, and cortisol imbalances. More info: http://drfairchild.blogspot.com/2012/12/thyroid-testing-and-treatment.html ...Read more
