I'm a healthy active 71 year old woman who's been on 50mcg levothyroxine for at least 10 years. The blood test numbers always show normal, but I feel cold much of the time, tired, bloated, depressed, with muscle aches and joint pain. I'm not sure how much of this can be attributable to normal aging. I eat a high fiber diet, including walnuts and soy products, which can inhibit the absorption of the drug. Is it possible my dosage needs to be increased? I will contact my doctor, but first want another opinion.
Since your yearly tests are fine, I suggest the endocrinologist can be of benefit. A normal part of aging is that the body temperature slowly becomes lower over time. When I was twenty, mine was 98.6. Just what they said is right. At 64, I am at 97.0. Aging, medications, diseases, activity are all part of this. People function fine at 97 or even lower. Remember that body temperature is an average. Your doctor can explain more. But don't increase the medication yourself. This would decrease the TSH number. The doctor will know what you need. The TSH should be between .3 to 3.0. Some docs say it is ok at 6.0 or higher. You would be very tired at that level.
