Hypoglycemia is a general term used to describe a mixed bag of symptoms that are due to a derangement of glucose metabolism. Under the strict medical definition, hypoglycemia mainly refers to a drop in fasting blood sugar below 50mg% (normal range 70-90mg%). This drop can be associated with differing symptoms depending on the rate at which the blood sugar falls. The causes of functional or reactive hypoglycemia (not absolute or fasting hypoglycemia) can be divided into 3 categories:
There are different interpretations given to different patterns seen on glucose tolerance testing. One such system describes three types of curves: Type 1 (Neuroglycopenic) This type results in a rapid rise in blood glucose within the first hour followed by a pronounced or precipitous drop in blood glucose in the second hour. Symptoms of this type of response are rapid mood swings, volatile personality, erratic behavior before and after eating. Possible cause of this response is gastric dumping, too large an insulin response (pancreatic problems) and glucose tolerance factor problems (liver problems). Type 2 (Adrenergic Type) After ingestion of glucose the blood sugar rises for the first three hours followed by a hypoglycemic rebound at 4 to 6 hours. Symptoms associated with this type of response are tiredness 2 hours after eating, allergic responses or food intolerances, and shakiness before meals. When blood sugar falls rapidly, the early symptoms are those brought on by a compensating secretion of adrenalin; these include sweating, weakness, hunger, racing pulse and an "inner trembling". This response can be due to adrenal cortical insufficiency or thyroid deficiency. Type 3 (The Flat Curve Response) In this case the blood glucose does not deviate more than +/- 15% from fasting level through the whole test. Symptoms that may appear are fatigue, apathy or hypotonia (poor muscle tone). These symptoms are due to poor digestion and absorption of nutrients. Patients with hypoglycemia of varying causes appear to show similar personality patterns, suggesting hypoglycemia can cause personality disorders. The term "hypoglycemia" may be better named "carbohydrate intolerance syndrome" and treated accordingly. |

GLOSSARY
Adrenal Insufficiency: Also known as Adrenal Exhaustion or Low Adrenal Function, this is a condition where the adrenal gland is compromised in its production of epinephrine, norepinephrine, cortisol, corticosterone or aldosterone. Symptoms include primarily fatigue, weakness, decreased appetite with ensuing weight loss, as well as nausea, vomiting, abdominal pain, diarrhea or constipation, or increased pigmentation of the skin. Cortical insufficiency (low or no corticosteroids) produces a more serious condition called Addison’s Disease, characterized by extreme weakness, low blood pressure, pigmentation of the skin, shock or even death.
Bipolar Disorder: Also known as manic-depression, this disorder is characterized by alternating periods of extreme moods, usually swinging from being overly elated or irritable (mania) to sad and hopeless (depression) and then back again, with periods of normal mood in between. The frequency of the swings between these two states, and the duration of the mood, varies from person to person.
Carbohydrates: The sugars and starches in food. Sugars are called simple carbohydrates and found in such foods as fruit and table sugar. Complex carbohydrates are composed of large numbers of sugar molecules joined together, and are found in grains, legumes, and vegetables like potatoes, squash, and corn.
DHEA: Dehydroepiandrosterone (DHEA) is a steroid produced by the adrenal glands and is the most abundant one found in humans. DHEA may be transformed into testosterone, estrogen or other steroids. It is found in the body as DHEA or in the sulfated form known as DHEA-S. One form is converted into the other as needed.
Diabetes Mellitus: A disease with increased blood glucose levels due to lack or ineffectiveness of insulin. Diabetes is found in two forms; insulin-dependent diabetes (juvenile-onset) and non-insulin-dependent (adult-onset). Symptoms include increased thirst; increased urination; weight loss in spite of increased appetite; fatigue; nausea; vomiting; frequent infections including bladder, vaginal, and skin; blurred vision; impotence in men; bad breath; cessation of menses; diminished skin fullness. Other symptoms include bleeding gums; ear noise/buzzing; diarrhea; depression; confusion.
Enzymes: Specific protein catalysts produced by the cells that are crucial in chemical reactions and in building up or synthesizing most compounds in the body. Each enzyme performs a specific function without itself being consumed. For example, the digestive enzyme amylase acts on carbohydrates in foods to break them down.
Fasting Blood Sugar: (FBS): Blood is drawn before breakfast (i.e., after fasting), then the glucose (sugar) in the blood is measured.
Glucose: A sugar that is the simplest form of carbohydrate. It is commonly referred to as blood sugar. The body breaks down carbohydrates in foods into glucose, which serves as the primary fuel for the muscles and the brain.
Glucose Tolerance Factor: (GTF): A compound containing chromium that aids insulin in regulating blood sugar levels.
Hormones: Chemical substances secreted by a variety of body organs that are carried by the bloodstream and usually influence cells some distance from the source of production. Hormones signal certain enzymes to perform their functions and, in this way, regulate such body functions as blood sugar levels, insulin levels, the menstrual cycle, and growth. These can be prescription, over-the-counter, synthetic or natural agents. Examples include adrenal hormones such as corticosteroids and aldosterone; glucagon, growth hormone, insulin, testosterone, estrogens, progestins, progesterone, DHEA, melatonin, and thyroid hormones such as thyroxine and calcitonin.
Hypoglycemia: A condition characterized by an abnormally low blood glucose level. Severe hypoglycemia is rare and dangerous. It can be caused by medications such as insulin (diabetics are prone to hypoglycemia), severe physical exhaustion, and some illnesses.
Hypothyroidism: Diminished production of thyroid hormone, leading to low metabolic rate, tendency to gain weight, and sleepiness.
Hypotonia: Lessened tension; arterial relaxation.
Insulin: A hormone secreted by the pancreas in response to elevated blood glucose levels. Insulin stimulates the liver, muscles, and fat cells to remove glucose from the blood for use or storage.
Metabolism: The chemical processes of living cells in which energy is produced in order to replace and repair tissues and maintain a healthy body. Responsible for the production of energy, biosynthesis of important substances, and degradation of various compounds.
Milligram: (mg): 1/1,000 of a gram by weight.
Nervous System: A system in the body that is comprised of the brain, spinal cord, nerves, ganglia and parts of the receptor organs that receive and interpret stimuli and transmit impulses to effector organs.
Protein: Compounds composed of hydrogen, oxygen, and nitrogen present in the body and in foods that form complex combinations of amino acids. Protein is essential for life and is used for growth and repair. Foods that supply the body with protein include animal products, grains, legumes, and vegetables. Proteins from animal sources contain the essential amino acids. Proteins are changed to amino acids in the body.
Schizophrenia: Any of a group of psychotic disorders usually characterized by withdrawal from reality, illogical patterns of thinking, delusions, and hallucinations, and accompanied in varying degrees by other emotional, behavioral, or intellectual disturbances. Schizophrenia is associated with dopamine imbalances in the brain and defects of the frontal lobe and is caused by genetic, other biological, and psychosocial factors.
Stomach: A hollow, muscular, J-shaped pouch located in the upper part of the abdomen to the left of the midline. The upper end (fundus) is large and dome-shaped; the area just below the fundus is called the body of the stomach. The fundus and the body are often referred to as the cardiac portion of the stomach. The lower (pyloric) portion curves downward and to the right and includes the antrum and the pylorus. The function of the stomach is to begin digestion by physically breaking down food received from the esophagus. The tissues of the stomach wall are composed of three types of muscle fibers: circular, longitudinal and oblique. These fibers create structural elasticity and contractibility, both of which are needed for digestion. The stomach mucosa contains cells which secrete hydrochloric acid and this in turn activates the other gastric enzymes pepsin and rennin. To protect itself from being destroyed by its own enzymes, the stomach’s mucous lining must constantly regenerate itself.
Thyroid: Thyroid Gland: An organ with many veins. It is at the front of the neck. It is essential to normal body growth in infancy and childhood. It releases thyroid hormones - iodine-containing compounds that increase the rate of metabolism, affect body temperature, regulate protein, fat, and carbohydrate catabolism in all cells. They keep up growth hormone release, skeletal maturation, and heart rate, force, and output. They promote central nervous system growth, stimulate the making of many enzymes, and are necessary for muscle tone and vigor.
