Brenda, a 48-year-old single mother, is the first to admit that she had an unhealthy lifestyle. "I ate a lot of sugar. A lot of junk food. I do not exercise," she says.
Brenda says she received a major wake-up call when she started having heart palpitations while driving in the car with her daughter. "At the time in which this was going on, I thought I was going to die," she says.
After running a biophysical on Brenda, Dr. Oz found that on top of being anemic and vitamin D deficient, Brenda had a thyroid problem. "Your thyroid levels were the worst they had ever seen," he says. "You weren't making any at all. That actually was leading to your muscle literally breaking down." Dr. Oz says this may have caused Brenda's heart palpitations. "Over and over again, especially in women, we see the thyroid gland not functioning correctly. And when it happens in the severe nature, you actually fall apart. And your heart muscle, which is one of the muscles, can also stop."
Since Brenda has been following the YOU: Staying Young plan, she says she is feeling much better. "I'm better able to handle stress, I work out regularly and I'm not as tired," she says.
Dr. Oz stresses the importance of taking care of thyroid problems by having your thyroid levels checked. "It's one of the key blood tests you have to get on yourself," he says.
