I need women to pay close attention here. I’m talking about thyroid hormones in excessive doses. Look in your box for levothyroxine. Brand names include Synthroid, Levoxyl, or Euthyrox. I’m almost certain many of you are holding this box right now.
Levothyroxine is one of the most prescribed drugs in the world. Millions of women over 50 take it every day for hypothyroidism. And let me tell you, the problem isn’t the medicine itself. Levothyroxine is an excellent drug. When the dose is right, it protects, it balances, it’s necessary. The problem is the dose. When the dose is higher than necessary, a condition we call iatrogenic hyperthyroidism (meaning it’s caused by the prescribed treatment), the excess thyroid hormone accelerates the bone remodeling cycle. And when I say accelerates, imagine this: instead of the bone rebuilding at a normal pace, the demolition team starts working at double speed. The construction team can’t keep up. The result is bone being destroyed faster than it’s being formed, every single day, silently.
Are you holding Puran T4 or Synthroid? Then answer me this: when was the last time you had your TSH checked? When was the last time your doctor re-evaluated your dose? Because many, and I mean many, women start on a dose and nobody adjusts it for 5, 8, or 10 years. The dose that was right at 55 might be too high at 65, and the excess is accelerating bone demolition without you feeling a thing. Your mission: go to your endocrinologist and ask, “Doctor, is my dose still appropriate? Do we need to re-evaluate?”
2. The Common Steroid That Kills Your Bone-Building Cells
Everyone knows this one. I’m talking about glucocorticoids, the famous corticosteroids. Look in your box for prednisone, prednisolone, dexamethasone, or deflazacort. Brand names include Meticorten, Prednicen, Decadron, or Calcort. This is the most well-known bone destroyer in medicine. It’s no secret; any doctor knows. But what many people don’t know is the speed at which it acts.
Corticosteroids are the most common cause of drug-induced osteoporosis worldwide. The medication is a triple threat. First, they kill osteoblasts, the builders, directly inhibiting new bone formation. The builders are sent home. Second, they reduce calcium absorption in the intestine. So even if you eat well, the calcium doesn’t get absorbed properly. Third, they increase calcium loss through the kidneys. Your body flushes calcium out in the urine. It’s a three-pronged attack.
And the most frightening part: bone density loss can begin in just three to six months of continuous use. Months, not years. And here’s the part that surprises many people. “Oh, Dr. Andre, but I don’t take prednisone.” What about that injection the orthopedist gave you for your back, knee, or shoulder pain? Often, that injection is a corticosteroid. The golden rule for corticosteroids is the lowest possible dose for the shortest possible time, and never stop it abruptly. Weaning must be done by a doctor.
