Safety of Liotrix10/19/2009 |
I have Hyperthyrodism and taking 100mcg of Synthroid. It recently was increased from 80mcg. I have a great problem with hairloss. Changing from Synthroid to Liotrix or Armour will it help or will my hairloss increase?Thank you very much.
Hypothyroidism is a condition in which too little thyroid hormone is produced from an underactive thyroid gland. Thyroid hormones regulate how the body breaks down food and either uses that energy immediately, or stores it for the future. In other words, our thyroid hormones regulate our body's metabolism.
The usual treatment for hypothyroidism is levothyroxine or T4. The dose of T4 is usually based on a person's weight and other medication or conditions that the person may be taking or experiencing. It usually takes a couple of weeks in most cases to reverse the symptoms of hypothyroidism once a person begins taking the T4. In some cases it may take longer to reverse symptoms such as increased hair loss. You need to work with you physician who can take blood work, which helps to guide her/him in adjusting your dosage of medicine.
If you take too much T4, you can develop a mild case of hyperthyroidism, which is too much thyroid hormone. This could cause muscle weakness, weight loss, vision changes, trembling hands, rapid heartbeat, fatigue, irritability and anxiety, intolerance to heat and sweating, and infertility.
With too little thyroid, The symptoms that occur with hypothyroidism include fatigue or tiredness, depression, feeling cold, weight gain, dry skin and hair, hair loss, constipation, hoarseness, loss of balance, memory & mental difficulties, decreased concentration and menstrual irregularities.
There are other forms of thyroid replacement that are not highly recommended because of the difficultly of absorption or getting into one's body after taking. These other forms can also vary in how strong each batch of medicine may be and the rate at which it gets into someone's system. This is sometimes referred to as potency and bioavailability. Armour Thyroid ® (desiccated thyroid) which is derived from pork thyroid and Liotrix, (thyrolar) contains both thyroxine (T4) and triiodothyronine, or liothyronine (T3). Combination therapy with levothyroxine and liothyronine is not recommended at this time by the American Association of Clinical Endocrinologists.
Thank you for visiting NetWellness.
