Some hormonal imbalances are from natural aging while others can range from stress to endocrine dysfunction. Others may be caused by side effects or medications.  Some just tend to worsen with age.  Some of the main causes of hormone imbalances are: Thyroid Dysfunction If your thyroid gland is not working properly it can cause abnormal thyroid levels considered either underactive or overactive. Chronic Stress Stress can have a major effect on your body’s cortisol levels which can then affect other hormones in your body. Birth Control or Hormone Replacement Drugs Most birth control and hormone replacement medications contain synthetic or “man-made” hormones which can cause numerous imbalances in the body.  Synthetic hormones are not natural to the body, and just by adding these common hormones to your body it can cause a myriad of symptoms. Medications Certain medications can cause a hormonal imbalance such as steroids and diabetes medications. Endocrine Disruptors Endocrine disruptors are common chemicals that mimic your body’s hormones and can cause severe hormone imbalances.  Common endocrine disruptors are toxins, pollutants, chemicals, herbicides, pesticides, plastics, environmental contaminations and certain foods we eat can interfere with the endocrine system. These are just examples of the many endocrine disruptors.
