Hormone Imbalance, Perimenopause, and Menopause
Hormones set the tempo for how you feel every day, and when they fall out of balance the effects reach everywhere, energy, mood, sleep, weight, libido, and clarity of thought. For many women, perimenopause and menopause bring these shifts into sharp focus, while men experience their own gradual hormonal decline. Recognizing the symptoms and understanding what is happening is often a relief in itself, because these changes are common, measurable, and manageable.
Hormone concerns are evaluated by Dr. James Petros, MD, founder of NexGen Health and a physician board certified in Anti-Aging Medicine, Functional Medicine, Regenerative Medicine, Physical Medicine, and Interventional Pain Management. With his medical degree from Tulane University School of Medicine and training at Stanford, Dr. Petros founded the practice in 2021 around bespoke, science-driven care, approaching hormones as one connected system rather than isolated numbers.
Recognizing Hormonal Change
Hormonal shifts produce a wide range of symptoms, and they often arrive gradually enough to be mistaken for stress or aging.
- Hot Flashes and Night Sweats: sudden heat and sweating linked to estrogen changes.
- Mood Swings: irritability, anxiety, or low mood that feels out of character.
- Sleep Disruption: trouble falling or staying asleep through the night.
- Fatigue and Low Energy: persistent tiredness not explained by activity.
- Weight Changes: gradual gain, especially around the midsection.
- Low Libido: reduced desire and changes in sexual function.
Understanding the Transition
In perimenopause, estrogen and progesterone fluctuate, often for years before menopause is complete, producing irregular cycles and shifting symptoms. In menopause, sustained low hormone levels affect bone, heart, brain, and metabolic health. Men experience a slower decline in testosterone that can bring fatigue, reduced strength, and mental fog. Thyroid, cortisol, and insulin imbalances frequently overlap, which is why testing tells a clearer story than symptoms alone.
