Not always, but according to Dr. Markowitz, sometimes unwanted hair growth in younger women can be a sign of something more serious.
"In younger age groups, this can be associated with certain diseases like Polycystic Ovary Syndrome or Syndrome X where women stop menstruating regularly and gain weight," she said. "These diseases are due to insulin resistance that cause hormonal imbalances that leads to hair in unwanted areas like the face and other unwanted side effects like increased weight gain."
Polycystic Ovary Syndrome, or PCOS, is a disease common among women. As we've previously reported, it affects six to 12 percent of people with female sex organs and is caused by ovaries that are enlarged by cysts. PCOS can also cause irregular or infrequent periods, excessive acne, and weight gain, so if you notice any of these symptoms accompanying your unwanted facial hair, it's best to reach out to a doctor.
