Sick of Being Tired? Sneaky Signs Your Thyroid Is Slacking Off



Dragging throughout the day after logging enough shut eye is one of the most common symptoms of an under-active thyroid.

For all the attention paid to the popularity of sleep medications, it’s surprising to find out that the No. 1 prescription drug in America is one that’s meant to help people out of bed.

With 23 million brand-name prescriptions filled between April 2013 and March 2014, according to IMS Health, the top pill popped in America is the synthetic thyroid hormone levothyroxine. The drug is used to treat hypothyroidism, which occurs when the body doesn’t produce as much thyroid hormone as it needs. Nearly 5 percent of U.S. adults have the condition, according to the most recent estimates available. And its most common form, Hashimoto thyroiditis, is now considered the most common immune disease in America. The number of prescriptions for levothyroxine has increased by more than 40 percent over the past five years.

Doctors say the number of prescriptions might vastly underestimate the disease’s true prevalence. According to the American Thyroid Association, up to 60 percent of people with some form of thyroid disease don’t know that they have it.

“It is now clear that the tests that we thought could easily determine if a person suffers from hypothyroidism are missing the majority of people who could benefit from treatment,” said Kent Holtorf, MD, medical director of the Holtorf Medical Group and president of the National Academy of Hypothyroidism.

In its first update on screening for thyroid dysfunction since 2004, the U.S. Preventive Services Task Force released a new draft recommendation Monday. The expert panel concluded that “the current evidence is insufficient” to recommend for or against screening adults without symptoms.

However, “That’s not necessarily great advice for each individual person to follow,” said endocrinologist Richard Shames, MD, author of Thyroid Mind Power. “Low thyroid is one of the most common illnesses in the country, and the symptoms are many and varied.”

Common symptoms complicate diagnosis

The symptoms of hypothyroidism read roughly like a description of the modern human condition: fatigue, weight gain, digestive issues, irritability, and depression, to name a few. High thyroid hormone (hyperthyroidism) is less common and can trigger weight loss and sleep difficulties.

“Some people have only one symptom, some people have several, and no person has the same presentation,”  “This is all due to the fact that thyroid is the metabolic gas pedal. But it’s a gas pedal that runs everything, not just the speed of the motor. It runs the volume of the radio, the crispness of the air conditioner, how fast the windows go up and down. That’s what a thyroid does—it’s your metabolic control. And no one thinks about it as long as it’s doing fine. It can affect anything, and that’s why it seems to affect everything.”

Internist and hormone expert Erika Schwartz, MD, has worked with more than 15,000 patients in prevention and hormone balance during her career. The following are the telltale signs of hypothyroidism, as Schwartz’s clients have described them to her.
