The glycemic index is a well-established way of classifying foods based on their potential to raise blood glucose (blood sugar).
Eating a big meal of only high GI foods will cause you to feel hungry only a few hours after that meal, because the blood sugar will dive sharply and this low blood sugar causes hunger again. Dr Dani is a Medical Doctor & American Board Certified in Integrative Medicine (ABIHM). Do we simply have to accept fatigue as part of the human condition, perhaps even rationalize it as natural…a stage of life, a mere symptom of getting on in years? Rather than think of ourselves in terms of an accumulation of years, we need to imagine ourselves in terms of how healthy we are. Fatigue, rather than being an illness unto itself, is a symptom that is often indicative of other more serious diseases. From the obvious to the extremely complex, the cause(s) of fatigue can be as varied and intertwined as the depleted individuals experiencing its affects. From hormone imbalances, adrenal dysfunction, and toxicity, to sleep disturbances, lack of exercise, and a diet too high in sugar and carbohydrates, the fact is while some of the causes are rooted in more serious medical conditions, many more causes are self-inflicted and almost totally avoidable. While constipation is technically an affect of other problems, rather than a direct cause for being tired, a colon cleansing speeds up your transit time, maximizing the elimination of stored toxins, and improving the quality of your blood. For people who do not have medical problems to take into consideration, the easiest way to treat fatigue is to make lifestyle and dietary changes…bit by bit finding ways to eliminate toxins from the body and minimize the intake of foods known to contain toxins, as well as by incorporating regular exercise into daily routines.
Many in the naturopathic field recommend that fatigue sufferers begin with a seasonal herbal colon cleansing or colonic hydrotherapy cleanses.
There are many little things, baby steps you can take to improve your overall health, and free up some of the energy that has been ebbing away from you. Start with one or two easy-to-implement lifestyle changes that will work toward long-term solutions to your fatigue. It’s vital to incorporate a rich, superior–grade multivitamin into your daily routine. Once you have taken care of medical considerations such as iron supplements for anemia, controlled blood sugar levels, supported your thyroid, and had antibiotics to treat any infection, it is crucial, as Dr. Detoxification: Regular cleansings help to rejuvenate your energy levels, especially if you suffer from heavy metal exposure or are sensitive to certain chemicals.
Endocrine glands are ductless glands that produce and release hormones to the blood through diffusion. Endocrine glands may be strictly endocrine, such as the pituitary, thyroid, parathyroid, adrenal, pineal and thymus; or they may be organs that have hormone production as one of many functions, such as the pancreas, gonads, hypothalamus, and others. Hormones are long-distance chemical signals that are secreted by the cells to the extracellular fluid and regulate the metabolic functions of other cells. Most hormones are amino acid based, but gonadal and adrenocortical hormones are steroids, derived from cholesterol. Water-soluble hormones (all amino acid-based hormones except thyroid hormone) exert their effects through an intracellular second messenger that is activated when a hormone binds to a membrane receptor. Lipid-soluble hormones (steroids and thyroid hormone) diffuse into the cell, where they bind to intracellular receptors, migrate to the nucleus, and activate specific target sequences of DNA. Target cell response depends on three factors: blood levels of the hormone, relative numbers of target cell receptors, and affinity of the receptor for the hormone.
The concentration of a hormone reflects its rate of release, and the rate of inactivation and removal from the body.


The half-life of a hormone is the duration of time a hormone remains in the blood, and is shortest for water-soluble hormones. Permissiveness occurs when one hormone cannot exert its full effect without another hormone being present (reproductive hormones need thyroxine to properly stimulate development of reproductive organs).
Synergism occurs when more than one hormone produces the same effects in a target cell, and their combined effects are amplified (glucagon + epinephrine together stimulate more glucose release from the liver than when each acts alone).
Antagonism occurs when one hormone opposes the action of another hormone (glucagon antagonizes insulin). Nervous system modulation allows hormone secretion to be modified by the nervous stimulation in response to changing body needs. The pituitary gland is connected to the hypothalamus via a stalk, the infundibulum, and consists of two lobes: the anterior pituitary, or adenohypophysis, and the posterior pituitary, or neurohypophysis. Two neurohormones are synthesized by the hypothalamus and secreted by the posterior pituitary.
Growth hormone (GH) indirectly (through insulin-like growth factors, IGFs) stimulates body cells to increase in size and divide.
Direct effects are insulin-sparing: mobilization of fatty acids for fuel, inhibition of insulin activity, release of glucose from liver to blood, and stimulation of amino acid uptake by cells. The thyroid gland consists of hollow follicles with follicle cells that produce thyroglobulin, and parafollicular cells that produce calcitonin. Thyroid hormone consists of two amine hormones: thyroxine (T4) and triiodothyronine (T3), that act on all body cells to increase basal metabolic rate and body heat production. The parathyroid glands contain chief cells that secrete parathyroid hormone, or parathormone.
The adrenal glands, or suprarenal glands, consist of two regions: an inner adrenal medulla and an outer adrenal cortex.
The adrenal cortex produces corticosteroids from three distinct regions: the zona glomerulosa, the zona fasciculata, and the zona reticularis. The adrenal medulla contains chromaffin cells that synthesize epinephrine and norepinephrine (stimulus is acetylcholine released by preganglionic sympathetic fibers). Insulin is an anabolic hormone and will stimulate not only glucose uptake but also storage in the form of glycogen (glycogenesis), fat (lipogenesis) and amino acid incorporation into proteins (inhibits amino acid breakdown by liver to form new glucose molecules - gluconeogenesis). Stimuli for insulin release are primarily high blood glucose levels but insulin release is also potentiated by rising blood levels of amino acids and fatty acids and release of acetylcholine by parasympathetic neurons (all of these things happen after a meal). Glucagon is released by the pancreas in response to low blood glucose levels (primarily) and raises blood glucose levels back to within normal range by stimulating glycogenolysis, gluconeogenesis, and release of glucose to the blood by the liver. Indirectly receives input from the visual pathways in order to determine the timing of day and night.
Adipose tissue produces leptin, which acts on the CNS to produce a feeling of satiety; secretion is proportional to fat stores.
Adipocytes also produce adiponectin, which enhances insulin activity, and resistin, an insulin antagonist. Osteoblasts in bone produce osteocalcin, which stimulates pancreatic beta cells to divide and secrete more insulin.
Adiponectin levels are low in type II diabetes, suggesting higher levels may help reverse the insulin resistance characteristic of type II diabetes. Endocrine glands derived from mesoderm produce steroid hormones; those derived from ectoderm or endoderm produce amines, peptides, or protein hormones.


Environmental pollutants have been demonstrated to have effects on sex hormones, thyroid hormone, and glucocorticoids. High glycemic index diets are typically composed of foods that produce a large rise in blood sugar after a meal and cause large amounts of insulin to get released.
Or it can simply be your body’s way of telling you that something is amiss in your life. Each instance of fatigue is unique, so in order to unravel the individual complexities behind each case, it is necessary for fatigue sufferers to work within a relationship of trust with his or her health care partner or naturopath. Since it’s not a life-threatening disease, many of us simply slough it off as something that happens because we take on too many things, which in some cases may be true.
This helps to remove toxins from your system, and ensures that all your body’s systems are functioning at their peak. The stimulus for GHRH release is low blood levels of GH as well as hypoglycemia, low blood levels of fatty acids, and high blood levels of amino acids. Hypersecretion of GH in childhood results in gigantism; in adulthood hypersecretion of GH causes acromegaly (increase in size of flat bones after epiphyseal plates of long bones have sealed). Thryroid releasing hormone (TRH) from the hypothalamus stimulates TSH release; Thyroid hormone (Thyroxine) exerts negative feedback control of both TRH and TSH. Excretion of ketoacids (with their negative charge) by the kidney is accompanied by loss of cations, particularly K+ and Na+. Secretion of resistin is proportional to fat stores; secretion of adiponectin is inversely proportional to fat stores. This causes stress in the body (INFLAMMATION) and causes the body to make new fat cells to store the extra sugar released from the high GI food you just ate.
She splits her time between her medical practice in Vancouver, Canada & her Wellness Centre in Bali. But feeling tired can run the gamut from being a symptom of an immune disorder such as Chronic Fatigue Syndrome, to just plain weariness. In many cases, the prognosis is good because fatigue can be a relatively easy problem to solve.
Others who are seriously concerned about the daily battles they fight with fatigue do not believe it is just natural, a part of the aging process. I can do this,’ and you will be inspired to do more to keep your body from tiring out. This will help to make up for what may be lacking in your food, as well as work to nourish your cellular functioning.
Being fatigued can affect your body in a range of ways that may seem disconnected to the exhaustion you feel.
Healthy nutritional choices can help boost your adrenals and energy, as well as curb your cravings for caffeine and sugar. It can sometimes be a complicated, ongoing, and involved process to determine the underlying cause(s) of a person’s fatigue.
