Highlights What is Hypothyroidism? Hypothyroidism, also called underactive thyroid, is a condition in which the thyroid gland does not produce enough hormone. Hypothyroidism can be caused by the autoimmune disorder Hashimotos thyroiditis, irradiation or surgical removal of the thyroid gland, and medications that reduce thyroid hormone levels. Anyone can develop hypothyroidism, but people who are most at risk include those who are over age 50 and female. However, only a small percentage of people have full-blown (overt) hypothyroidism. Many more have mildly underactive glands (subclinical hypothyroidism). Symptoms Symptoms of hypothyroidism include: Fatigue Difficulty concentrating Feeling cold Headache Muscle and joint aches Weight gain, despite diminished appetite Constipation Dry skin Coarse hair, hair loss Hoarse voice Depression Menstrual irregularities (either heavier-than-normal or lighter-than-normal bleeding) Milky discharge from the breasts (galactorrhea) Diagnosis and Treatment Hypothyroidism ...
Medications Thyroid Hormone Replacement The goal of thyroid drug therapy is to provide the body with replacement thyroid hormone when the gland is not able to produce enough itself. A synthetic thyroid hormone called levothyroxine is the treatment of choice for hypothyroidism. This drug is a synthetic derivative of T4 (thyroxine), and it normalizes blood levels of TSH, T4, and T3. Brand Names . A number of levothyroxine brands are available. Synthroid is the oldest brand and has been used for over 40 years. In the past, manufacturers of levothyroxine did not need to meet as strict standards as in the production of other drugs. This resulted in thyroid products with varying quality. The FDA has issued stronger requirements that have largely corrected this problem. Generics versus Brand-Name Products. Generic brands are available and are subject to the same FDA guidelines as brand-name products. There is still debate over whether generic thyroid preparations are as effective as brand products...
Full Question :
I have excruciating headaches from morning to night. I also have
hypothyroidism. While I am been treated with T3 at this stage, my TSH is still
not regulated. Last results showed TSH >73 mIU/L. Could this be partly
responsible for the headaches? Fiona.
Simply put -- it's possible. We often find that thyroid levels play a
significant role in headache and Migraine disease. Still, you should mention
this to your doctor and take care not to use either prescription or over-the
counter pain relievers more than two or three days a week to avoid medication
overuse headache .
Good luck, John Claude Krusz and Teri Robert
