Came across the following statement and I don't have a link for it. I thought it would be useful for some members:-
"Question: I am a physician and I treat hypothyroid patients. Partly because of your writings, some of my patients want more thyroid hormone than ordinary replacement doses. Over the past year, I've found that the higher doses usually work better. I am very concerned, however, about one thing. Many of these patients are middle-aged, deconditioned, and I assume that they have some degree of coronary artery disease. My worry is that the higher doses may cause myocardial ischemia in the patients. In your experience, is this a concern with middle-aged patients?
Dr. Lowe: As I emphasized in The Metabolic Treatment of Fibromyalgia
In most patients, then, TSH-suppressive doses of thyroid hormone don’t harm the heart. This justifies Dr. L.E. Shapiro writing in 1997, "In the absence of symptoms of thyrotoxicosis, patients treated with TSH-suppressive doses of L-T4 may be followed clinically without specific cardiac laboratory studies."[2]
Dr. Gordon Skinner recently wrote that patients with normal thyroid test results who have symptoms and signs of hypothyroidism should be permitted undergo a trial of thyroid hormone therapy. Anticipating objections, Skinner wrote, "The dangers of osteoporosis and cardiac catastrophe—particularly during a three-month trial—are sometimes quoted, but these worries are unfounded and condemn many patients to years of hypothyroidism with its pathological complications and poor quality of life."[3] A correct interpretation of the available scientific evidence compels one to agree with Dr. Skinner.
As I said, some conventional endocrinologists have grossly exaggerated the cardiac risks of TSH-suppressive doses of thyroid hormone. When doctors exercise reasonable precaution with their patients, they can safely ignore these endocrinologists’ exaggerations.
