Dr. Andrew Heyman explains that as men and women age, their hormones change. This hormonal change can be slow and gradual or can be sudden, bringing with it health issues associated with aging. You could be noticing depression and mood changes, weight gain, achiness and joint stiffness, blood pressure changes, numbness or tingling in the toes, feet or hands, loss of muscle and strength, cognitive decline, blood sugar imbalances, dizziness and even changes in your sex drive. You may not realize these issues are related to changes in your hormones. How your hormones are working in your body is influenced by the balance between different hormones – the interrelationship between the hormones, and whether your body is metabolizing (processing) them properly and if any environmental toxins are blocking their effects.
