OKLAHOMA CITY, OK – October 20, 2026 – Most women begin the menopausal transition between ages 45 and 55, and the average age of menopause in the United States is 52, according to the National Institute on Aging. Dr. Cassie Smith, MD, a dual board-certified endocrinologist and the founder of Modern Endocrine in Oklahoma City, described how her practice approaches the symptoms that bring women in during those years.
“A woman tells her doctor she’s waking up soaked at three in the morning and can’t find words she used to find easily, and the answer is that this is what her age looks like,” said Dr. Cassie Smith, MD, founder of Modern Endocrine. “Sometimes that’s true. But it’s a conclusion you reach after measuring, not instead of measuring.”
How the transition is recognized
The National Institute on Aging lists hot flashes, night sweats, trouble sleeping, joint and muscle discomfort, moodiness, forgetfulness and difficulty concentrating among the symptoms the menopausal transition can bring. It also notes that some midlife changes may be part of aging rather than menopause itself, and that it can be difficult for a woman and her doctor to tell whether the transition has started.
According to the institute, a doctor may ask about a woman’s age, symptoms and family history to judge whether the menopausal transition is the likely cause. In some cases, for example when periods stopped at an early age, a doctor may suggest a blood test to check hormone levels. Menopause is confirmed only once a woman has gone a full year without a period or spotting.
What testing is for at Modern Endocrine
Dr. Smith’s practice uses lab work to separate symptoms that trace to hormones from symptoms with another cause. Its evaluation reads hormone levels alongside thyroid function, metabolism and gut health, so that a result pointing away from estrogen still gives the patient and her physician something to investigate next.
“Testing isn’t there to talk anyone into treatment,” said Dr. Smith. “Half the value is ruling things out. If estrogen isn’t the problem, a woman deserves to hear that too, along with where we’re going to look next, whether that’s thyroid, insulin, cortisol or sleep.”
The National Institute on Aging notes that many women find they do not need treatment for menopause symptoms, and that the decision belongs in a conversation with a doctor about symptoms, medical history and preferences.
