The research is conducted to explain the aims, Pathophysiology of Hypoglycemia, causes and effects of Hypoglycemia, Somogyi effect and Dawn phenomenon. In this document there is guidance relating to low blood sugar, precautions which can be adopted to maintain blood sugar level.
The term – Hypoglycemia is derived from the Greek words in which “hypo” means low “glykys” means sweet and “haima” means blood. Hypoglycemia is a scientific word for peculiarly less quantity of sugar (glucose) in the blood (Ferry, n.d). This is the condition within which serum glucose intensity (the glucose or sugar amount in the blood) drops under 70mg/dl that recognized as Hypoglycemia, and is potentially dangerous.
It is usually caused by undue oozing of insulin by the islet cells of the pancreas. If insulin secretion is too much it results in hypoglycemia and if insulin secretion is too less it results in hyperglycemia. If no insulin is secreted, the result is diabetes (Dherbs, n.d).
Aim: The objective of the study is -
Getting Top Grades is No Longer a Dream for You.

REGULATION OF GLUCOSE HOMEOSTASIS:
During normal condition insulin and glucagon regulates the extracellular supply of glucose. When the glucose level increases after a meal, glucose enters the pancreatic beta-cells. Inside the cells, phosphorylation of glucose-6-phosphate is under taken by the enzyme glucokinase. This function as the glucose sensor, which leads to series of incidences enabling the entry of calcium and release of insulin hormone.
The function of insulin is to help in restoration of normoglycemia by the following two ways:
Such responses cause reticence of production of hepatic glucose and enhance marginal consumption of the glucose load, which is not taken up by the liver. As a consequence, level of plasma glucose generally returns to baseline values within quite a few hours (Cryer, 2011).
To protect the brain, several physiological mechanisms control the effects of hypoglycemia. In a non diabetic adult when glucose cannot be obtained from the intestinal absorption of food, the plasma glucose concentration starts declining. Glucose counter regulatory mechanisms prevent falling plasma glucose concentrations in blood. This mechanism starts before the onset of symptoms of hypoglycemia.
Impairment of behavioral and counter regulatory responses- In diabetic patients Hypoglycemia is the effect of the interaction of relative or absolute restorative insulin excess and compromised behavioral and physiological defenses against declining glucose level of blood.
Previous investigation done in United States of America and Britain compared such responses in older plus young non-diabetic adults yielded confounded interpretation and conflict results of the data, due to several participants had co-morbidities. These results are of less value, as hypoglycemia was persuaded mostly by an intravenous bolus vaccination of insulin.
According to clamp studies on evaluating young and elderly non-diabetic people, it was determined that –
At times the glucose level of blood goes under 60 mg/dL, hypoglycemia symptoms begins appearing. Several time individual might feel symptoms on the above of such level. Lessening of blood glucose amount below 50 mg/dL is very unsafe as brain is greatly affected.
Early symptoms – The hormone Adrenaline is the major hormones released during hypoglycemia. It causes the majority of the early symptoms.
Symptoms later set – When brain remnants deprived of glucose than symptoms later set follows:
Scientifically the hypoglycemia is classified into two categories:
o Neurogenic (autonomic) – Lessening level of glucose and cause patients to identify that they are experiencing a hypoglycemia incident. Stimulated by the ANS and are arbitrated in part through sympathoadrenal discharge of catecholamines (epinephrine and nor epinephrine) from the adrenal acetylcholine and medullae from postsynaptic sympathetic nerve finishing’s.
The symptoms of Neuroglycopenic takes place as a consequence of deprivation of brain neuronal glucose. Its symptoms comprises –
In a diabetic patient the insulin effects is drastically eliminated. It is due to doesn’t enough produce of pancreas (type 1 diabetes) or because cells are not as much of responsive to it (type 2 diabetes). In order to deal with such situation patient generally depends on insulin or several other drugs premeditated to lower levels sugar of blood.
If an individual takes so many insulin relative to the level of glucose in your streams of blood than it gives result in blood sugar lessening concentration i.e. hypoglycemia. After the diabetes medication patient should take adequate amount of food, in absence of this i.e. after diabetes medication if patient do not take meal or exercise more than the normal, hypoglycemia may be caused.
It is not always the case that the hypoglycemia occurs before meals but sometimes it may also be caused after meals. It may be due to more production of insulin in the body than actually required. This type of hypoglycemia is referred as postprandial or postprandial hypoglycemia. It is observed in the patients who have undergone gastric bypass surgery as well as in other people who haven't had surgery (Mayo Clinic Staff, 2012).
Hypoglycemia has following effects:
The stress hormones adrenaline is produced by the Adrenal gland in response to the message given by the body at the times when level of insulin is much high as well as sugar level of blood is low. On adrenaline secretion, insulin is “turned off” as well as it continues to sustain balance via adaptation. The experiences of hypoglycemic person are panic, fear and terror. This is due to fuel (glucose) deficient of brain and concurrently it is flooded with stress hormones-adrenaline, as a result of emotions symptoms (like nightmare, palpitation, panic attacks, nervousness, rage, violence, phobias and even fits) occur.
“Over time steady attacks and stress of over secretion hormones deplete the body resistance and might also degrade organs of the body, resulting in adrenal fatigue as well as finally loss of pancreas causing diabetes. Thus, anxiety in hypoglycemia person is a consequence of over emission of stress hormones and immediate concentration of low blood sugar.
According to research, it was identified that there is an association among low levels of GABA and more levels of insulin. GABA acts as neurotransmitters and supports in inhibition of calming the body and stress signals. Benzodiapienes and Valium work by raising level of GABA (During and et. al., 1995).
Several times hypoglycemia could cause other illness, such as arthritis, ulcers, mental disorders, impotence, allergies, epilepsy and asthma. Functional hypoglycemia has been removed in person with such disorders as hyperactivity, delinquency and obesity, drug addiction, alcoholism, juvenile delinquency, schizophrenia (Hypoglycemia, n.d).
