How coffee causes exhaustion, fatigue and addiction, Pt 6

Dr. Hibbs describes a male patient suffering from many effects of stress, including fatigue and constipation. The patient relied heavily on coffee to keep him going physically and had developed chronic adrenal fatigue. Dr. Hibbs took him off caffeine and sugar, which are both stimulants and were taxing his system. Appropriate exercise and dietary changes were made and he was put on adrenal supportive supplements containing glandular tissue, herbs, and nutrients. His bowel habits normalized quickly and remained that way when he stopped the adrenal supplements several months later.

The adrenal exhaustion/stress/fatigue/hypoglycemia syndrome is tied to caffeine use as well. Caffeine has an overall effect of increasing blood sugar (especially when it is sweetened), as it stimulates the adrenals. Both stress and sugar use tend to pressure and weaken the adrenal function. Recovery from the resulting fatigue requires rest, stress reduction, and sugar avoidance, but caffeine can override this fatigue and restimulate the adrenals. This process can eventually lead to chronic fatigue, adrenal exhaustion, and subsequent inability to handle stress and sugar intake. Caffeine will then be of little help.

Research is revealing that cortisol and DHEA, both produced in the adrenal cortex, hold an inverse relationship. As serum cortisol increases, DHEA levels fall. It may be that stress and caffeine create such a high need for cortisol that the exhausted adrenals simply cannot maintain production of DHEA at optimal levels.

Caffeine is undeniably an effective central nervous system stimulant. It stimulates the brain, increases the secretion of adrenaline (epinephrine), and boosts heart rate. Although relatively safe, long-term use in excess of 250 to 300 mg daily may cause numerous health problems. Caffeine has been known to raise blood-cholesterol levels, deplete B vitamins, irritate the stomach and bladder, exhaust the adrenals, and possibly lead to breast and prostate problems.

Far too many people overconsume caffeine, however. This occurs, I think, because people simply do not have enough natural energy. Instead of getting enough sleep, nutrients, and exercise to provide the energy they need, people depend upon caffeine to push them through the day. The short-term price for this dependency is nervousness, irritability, insomnia, and a "rebound effect" of lethargy and mental lassitude. The long-term price is burnout of the adrenal glands, and a body that has been exhausted by artificial stimulation.

Fatigue, childbirth, or injury to the kidney-adrenal area, also steroid drugs or excess use of stimulants, including caffeine, to the point of adrenal exhaustion, can all harm sexual strength for men and women alike. Muscles can become weak. Blood circulation and nerve sensitivity can become impaired. These are important factors in sexual strength. Some sexologists think of the vagina as a muscle.

According to Leon Chaitow, N.D., D.O., dizziness when standing after sitting or lying down can be an indication of adrenal exhaustion. The individual should take action to restore adrenal health by stopping the use of stimulants (caffeine, tobacco, alcohol) and via rest and normalization of lifestyle and nutritional balance.

"In other words, caffeine affects your body just like any drug: Addiction and withdrawal"

Caffeine is the most widely used drug in the world. Studies show that abstinence induces a withdrawal syndrome of fatigue, headache and drowsiness within 24 hours and lasts about a week, on giving up the habit.
Bartrams Encyclopedia of Herbal Medicine by Thomas Bartram, page 83

The second way that caffeine contributes to depression is, of course, the withdrawal reaction, the most prevalent symptoms being headache, depression, and fatigue. Three facts are important to grasp in regard to withdrawal. First of all, each of the symptoms compounds or magnifies the depressive effect. Secondly, withdrawal can occur even in light caffeine users. And third, withdrawal reactions can be evident even when caffeine is withheld for just a few hours. Some people feel depressed or anxious if they’re simply late for their morning or afternoon cup. That’s not only a powerful motivation to consume the beverage, but it also creates an often-unidentified source of background stress.

Almost all of the research that has been done on caffeine agrees that it is definitely physically addictive. It is a mood-altering central nervous system stimulant. Though milder in its effects, caffeine manipulates the same neurochemical channels that amphetamines, cocaine, and heroin do. Overuse of caffeine can result in a variety of symptoms, including irregular heartbeat, sleeplessness, headaches, nervousness, tremors, irritability, and depression. Withdrawing from heavy caffeine use can cause symptoms, too, principally a nagging headache that is unaffected by aspirin or other over-the-counter painkillers, as well as fatigue, muscle pain, lethargy, and feelings of depression. To break a caffeine addiction, therefore, it is best to cut down gradually to avoid an uncomfortable withdrawal period.
