The Most Trusted Lab for Hormones
Since 1998, ZRT has tested the hormones of 1.25 million women around the world.
Menopause is not a single point in time when hormone production is switched off for good, but a gradual evolution that brings an end to female fertility. The ultimate pause in ovarian function is a normal feature of growing older that reshapes the way women think and feel as they phase into their “second adulthood.”
The right balance of hormones is vital to a woman’s health. But in menopause, when levels are dropping, a deficiency of one hormone can trigger a relative excess of another and result in common imbalances such as:
Results in mood swings, migraines, fat gain in hips and thighs
Triggers hot flashes, night sweats, palpitations, foggy thinking, memory lapse & vaginal dryness
Leads to decreases in bone or muscle mass, metabolism, energy, strength, stamina, exercise tolerance & libido
Results in insomnia, anxiety, sugar cravings, feeling tired but wired & increased belly fat
Causes chronic fatigue, low energy, food and sugar cravings, poor exercise tolerance or recovery & low immune reserves
Changes in estrogen and progesterone levels can impact neurotransmitter levels. For instance, a drop in estrogen can result in a drop in serotonin.
Changes in estrogen levels can lead to thyroid symptoms like slowed metabolism and always feeling cold. In fact, many women experiencing menopause will be diagnosed with hypothyroidism.
Sufficient levels of Vitamin D, estrogen and testosterone are important for maintaining bone health in the menopause years.
