About This Presentation

Description : Check out this medical PowerPoint presentation titled "Hypoglycemia" by Mahtab Niroomand MD.

This medical PowerPoint presentation talks about hypoglycemia, a condition characterized by low blood sugar levels, typically defined as a glucose level below 70 milligrams per deciliter (mg/dL). Glucose is the primary source of energy for the bodys cells, including the brain, so low blood sugar can cause a variety of symptoms and complications.

Hypoglycemia can be caused by a variety of factors, including Diabetes, Some medications, such as beta blockers and some antidepressants, Excessive alcohol consumption and Some medical conditions, such as liver disease and kidney failure.

Definition All episodes of an abnormally low plasma glucose concentration that expose the individual to potential harm A single threshold value for plasma glucose concentration that defines hypoglycemia in diabetes cannot be assigned because there are varying threshold for symptoms
Slide 5-

Introduction Hypoglycemia is the most common endocrine medical emergency. Hypoglycemia is a clinical syndrome due to underproduction and or over utilization of glucose .

RESPONSE TO HYPOGLYCEMIA IN NORMAL SUBJECT Normal subject : Ability to suppress insulin release Increase counter-regulatory hormones
Slide 13-

Response to hypoglycemia in Diabetic patient Protective response to hypoglycemia impaired in many diabetic patient: Insulin release cannot turn off Effectiveness of counter-regulatory reduce
Slide 14-

IMPAIRMANT OF COUNTERREGULATORY RESPONSES IN DIABETIC PATIENT Glucagon response to hypoglycemia markedly impaired first few years Normal at onset of Diabetes Patient with glucagon secretion defect dependent to epinephrine protection which may impaired due to autonomous neuropathy.
Slide 15-

HYPOGLYCEMIA-ASSOCIATED AUTONOMIC FAILURE (1) Reduced counter regulatory hormone responses, which result in impaired glucose generation (2) Hypoglycemia unawareness, which precludes appropriate behavioral responses, such as eating.
Slide 16-

Hypoglycemia unawareness is reversible and require more than 2 weeks avoidance of hypoglycemia.

Etiology
Slide 23-

Etiology in adults 1. Fasting ( more than 5 hours P.P ) 2. Postprandial (Less than 5 hours P.P)
Slide 24-

Fasting hypoglycemia a. Underproduction: Alcoholism Organ failure Diffuse hepatic failure Uremia Endocrine deficiency G.H Glucocorticoid Catecholamines Glucagon Hypothyroidism Drugs Inanition b. Over utilization: Prolong exercise Sever sepsis Mesenchymal tumors Hepatoma - Sarcoma Lymphoma - Carcinoma… Hyperinsulinism Drugs Autoimmune insulin syn. Insulinoma Insulin receptor Ab.

HYPOGLYCEMIA IN DIABETES
Slide 28-

HYPOGLYCEMIA IN DIABETES Never occurs in patients on diet and exercise . Rare occurs : α glucosidase inhibitors, biguanides and thiazolidinediones. exceptions: elderly chronically ill patients prolonged fasting. More frequent occurs on s.urea and especially insulin
Slide 29-

HYPOGLYCEMIA IN DIABETES Insulin (or oral agent) doses are excessive, ill timed, or of the wrong type 2) Influx of exogenous glucose is reduced (e.g., during an overnight fast or following missed meals or snacks) 3) Insulin-independent glucose utilization is increased (e.g., during exercise) 4) Insulin sensitivity is increased (e.g., with effective intensive therapy, in the middle of the night, late after exercise, or with increased fitness or weight loss) 5) Endogenous glucose production is reduced (e.g., following alcohol ingestion) 6) Insulin clearance is reduced (e.g., in renal failure).

Clinical Manifestation
Slide 31-

Clinical manifestation 1. Neuroadrenergic: ( B.S < 55 - 60 ) Sweating Hunger Tremor Tingling Palpitation Anxiety Hypertension
Slide 32-

2. Neuroglycopenia: ( B.S < 45 - 50 ) Nonspecific: Headach - restlessness - aggressiveness - bizarre behavior - weakness Focal sign: Monoplegia - babinski - paresthesia - diplopia - trismus - vision loss Global sign: Stupor - convulsion - flaccidity - hypothermia - decerebrate rigidity - coma

Classification
Slide 36-

Harm of Clinically significant hypoglycemia Falling Motor vehicle accidents and other injueries Increased risk of dementia (older adults)
Slide 37-

Diagnosis 1. Pseudohypoglycemia: a. Lab.error b.Over utilization: Leukemoid reaction - Leukemia Hemolytic crisis - Polycytemia Vera c. Incorrect method for analysis: Lipemic serum
Slide 38-

Definition Hypoglycemia is threshold dependent B.S less than 45 - 50 mg/dl with symptoms recovery with treatment. ( Whipple triad )
Slide 39-

Differential Diagnosis T.I.A Epilepsy Orthostatic hypotension Arrhythmia
Slide 40-

Treatment
Slide 41-

Treatment Urgent Treatment necessary. When possible sample for documentation of plasma glucose should be obtained prior to treatment glucose administration need not delay until the result for initial sample report.
Slide 42-

Treatment ( emergency ) 1. Conscious patient: Ingestion of 5-20 gr. Soft drink or sugar… 2. Unconscious patient: a) Bolus : I.V 0.5 - 1 g/kg of hypertonic glucose b) maintenance : 5 - 10 g/h of glucose infusion. c) Glucagon : 0.5 - 1 mg I.v - I.m - S.c ( repeat ) 3. Post hypoglycemic coma: Hydrocortison 100 mg /t.I.d 20% Mannitol 200 cc/20 min
Slide 43-

Treatment(emergency) For treatment of BG <70 mg/dl in a patient who is alert and able to eat and drink, administer 15–20 g of rapid-acting carbohydrate such as:a one–15–30 g tube glucose gel or (4 g) glucose tabs (preferred for patients with end stage renal disease). 4–6 ounces orange or apple juice. 6 ounces regular sugar sweetened soda.
Slide 44-

Treatment(emergency) For treatment of BG <70 mg/dl in an alert and awake patient who is NPO or unable to swallow, administer 20 ml dextrose 50% solution iv and start iv dextrose 5% in water at 100 ml/h.
Slide 45-

Treatment (emergency) For treatment of BG <70mg/dl in a patient with an altered level of consciousness, administer 25 ml dextrose 50% (1/2 amp) and start iv dextrose 5% in water at 100 ml/h. In a patient with an altered level of consciousness and no available iv access, give glucagon 1 mg im. Limit, two times. Recheck BG and repeat treatment every 15 min until glucose level is at least 80 mg/dl
Slide 46-

hypoglycemic patient cause by regular insulin excess-nutritional deficit or alcohol can be stabilized and discharged. hypoglycemia caused by intermediate or long acting insulin, First generation or second generation sulfonylurea at risk for prolong hypoglycemia Treatment (emergency)
Slide 47-

ADA Recommendation Individuals at risk for hypoglycemia should be asked about symptomatic and asymptomatic hypoglycemia at each encounter
Slide 48-

ADA Recommendation Glucose (15–20 g) is the preferred treatment for the conscious individual with hypoglycemia (glucose alert value of <70 mg/dL), although any form of carbohydrate that contains glucose may be used. Fifteen minutes after treatment, if SMBG shows continued hypoglycemia, the treatment should be repeated.
Slide 49-

ADA Recommendation Once SMBG returns to normal, the individual should consume a meal or snack to prevent recurrence of hypoglycemia
Slide 50-

ADA Recommendation Glucagon should be prescribed for all individuals at increased risk of clinically significant hypoglycemia, defined as blood glucose ,54 mg/dL,so it is available should it be needed. Caregivers, school personnel,or family members of these individuals should know where it is and when and how to administer it. Glucagon administration is not limited to health care professionals
Slide 51-

ADA Recommendation Hypoglycemia unawareness or one or more episodes of severe hypoglycemia should trigger reevaluation of the treatment regimen. E
Slide 52-

ADA Recommendation Insulin-treated patients with hypoglycemia unawareness or an episode of clinically significant hypoglycemia should be advised to raise their glycemic targets to strictly avoid hypoglycemia for at least several weeks in order to partially reverse hypoglycemia unawareness and reduce risk of future episodes. A
Slide 53-

ADA Recommendation Ongoing assessment of cognitive function is suggested with increased vigilance for hypoglycemia by the clinician, patient, and caregivers if low cognition or declining cognition is found. B
