Stress and Hormone Balance

According to the Random House Dictionary, "Stress": can be physical, emotional or mental tension—or any factor that would cause these things. Physical stressors include such things as illness, severe injury, surgery, food allergies, chemical sensitivities, heavy metal exposure and poor nutrition. Emotional and mental tensions can result from a host of sources, such as job expectations, work overloads, parenting challenges and relationship problems. Beyond the hormones that we know as the 'sex hormones, estrogen, progesterone and testosterone, the body relies on many other hormones, such as insulin, cortisol, adrenaline, and serotonin.

In response to a stressful event, the body revs up the sympathetic nervous system—the so-called ‘fight or flight’ mechanism. The adrenal glands quickly release adrenaline and cortisol to provide the needed energy. A process called gluconeogenesis actually causes the breakdown of muscle protein so that amino acids can be released into the bloodstream. These aminos are then used by the liver to manufacture needed glucose, which raises the blood sugar level, supplying the brain with instant usable energy. In a normal stress response—like a near-miss car collision—the body sends out substances after the event to normalize (reduce) the levels of cortisol and adrenaline. Our shaking hands and pounding heart eventually return to normal. When we remain in a state of perceived stress for hours or days at a time, a host of problems can result due to the continued presence of cortisol. Blood sugar levels (insulin) remain elevated. Blood pressure can also remain elevated. Progesterone, needed for synthesis of cortisol, is being gobbled up by the adrenal system and is diverted away from other functions. Before long, a woman’s body can become progesterone-deficient and thyroid function may be compromised. (hypothyroid) A weakened adrenal system also fails to produce adequate levels of DHEA, leading to premature aging, low sex drive and cardiovascular problems.

DHEA , aldosterone and pregnenolone (and that's just a brief list!), to regulate ongoing bodily functions. It can negatively affect mental health, bone health, colon health , cardiovascular health, immune function and hormone balance.

Continuous, prolonged stressors can result in adrenal fatigue or worse, complete adrenal exhaustion. Exhausted adrenals produce less and less progesterone, which will most likely result in estrogen dominance. Cortisol also appears to block the efficient conversion of thyroid hormones, resulting in fatigue, weight gain, depression, brain fog and fibromyalgia symptoms.

Another adrenal hormone, aldosterone, is necessary for regulating the balance of minerals, chiefly sodium, potassium and magnesium. When stress causes a release of this hormone over an extended period of time, potassium deficiency and magnesium imbalance can occur, leading to high blood pressure and water retention. Cortisol may also contribute to hot flashes as it is thought to compete with estrogen and progesterone receptor sites.

There is a definite correlation between ongoing excess cortisol and weight gain. The pressures of Western culture, such as job expectations, unrelenting financial difficulties, lack of proper exercise and poor nutrition, can cause the adrenal system to collapse under the weight of it all. Pregnenolone, also called 'the mother hormone', is thought to be diverted away from the proper pathways during times of stress. This phenomenon is called 'pregnenolone steal'. This malfunction 'steals' hormone materials from the metabolic pathway that would normally be used for progesterone, DHEA, testosterone and estrogen production. Instead, it is diverted down another pathway and converts into more and more cortisol.

Several herbal and nutritional supplement companies have jumped onto the scene, promising to rescue us from this stress hormone. You may have heard or seen ads promoting such products as Cortislim and Relacor. These products claim to assist with weight loss by reducing the amount of cortisol in circulation.

Karen Collins of the American Institute for Cancer Research confirms the link to between stress, cortisol and weight problems and writes, “Some research suggests that cortisol may affect where body fat is stored. In one study, baseline levels of cortisol had no relation to women’s fat distribution. But those whose cortisol levels jumped the most in response to stress tended to have proportionally more waistline fat – even if they had a healthy weight. A greater proportion of fat at the waist was related to increased levels of ongoing stress related to work or finances, or lower levels of self-esteem. This waistline fat that gives people an apple shape poses the greatest health risks….”

What's the connection to osteoporosis ?

Stress causes magnesium to be excreted at an abnormal rate. Calcium, magnesium and potassium need to be present in proper levels to prevent bone loss. Also, the very presence of magnesium can lessen the stress response in the first place. For many reasons, it is a critical nutrient for healthy bones.

There are many things that you can do to combat stress-induced hormone imbalances.

First and foremost, support your body with quality food choices and extra antioxidants, such as vitamin C and B-complex. Other supplements might include magnesium (see Natural Calm below), pantothenic acid, L-theanine and kava. Support your mind and mental health with physical exercise, supportive friends, and relaxation and/or meditation techniques. If you don’t already own one, consider adopting a pet at your local animal shelter. Make quality time a priority with your family. Volunteer in your community or get involved with a local church or synagogue. Remember, doing something for others is always a good tonic.
