136 Possible Causes for Syncope, Variable Hypoglycemia

  • Hypoglycemia

    Glycemic variability portends increased risk for hypoglycemia and should be a focus of further research.[ncbi.nlm.nih.gov] A 64 year-old African female was brought to the emergency room with a 1-month history of recurrent syncope, weight loss, and abdominal bloating.[ncbi.nlm.nih.gov] The symptoms include being: Hungry Shaky Sleepy Anxious Dizzy Confused or nervous Sweaty Irritable Syncope (Passing out, losing consciousness) Some people have trouble speaking[hormone.org]

  • Cardiomyopathy

    […] present Hypoglycemia Hepatomegaly Cardiomyopathy Lab Fasting ketogenesis: Low Diagnostic testing Organic acids Normal with random testing or during myalgic episode Hypoketotic[neuromuscular.wustl.edu] Dogs diagnosed this way had more VPCs, polymorphic VPCs, couplets, triplets, VTs and R-on-T-phenomenon and syncope, decreased right ventricular function and dilatation in[ncbi.nlm.nih.gov] The following symptomatology may be seen in patients with HCM: Dyspnea Pre-syncope or syncope Chest pain Orthopnea Dizziness Paroxysmal Nocturnal Dyspnea (PND) Palpitations[symptoma.com]

  • Autonomic Neuropathy

    […] an algorithm for prediction of hypoglycemia in both bedbound and active patients with type 1 diabetes (T1D).[ncbi.nlm.nih.gov] Here, we report clinical characteristics and patterns of autonomic involvement in a 75-year-old patient who presented with recurring syncopes.[ncbi.nlm.nih.gov] Sometimes, this may cause dizziness or even fainting (syncope). In most cases, a cause for the POTS is never identified.[symptoma.com]

  • Ventricular Arrhythmia

    No direct correlation could be found among different variables of glucose profile, corrected QT interval, and ventricular arrhythmias.[care.diabetesjournals.org] Symptoms seem to be aggravated by emotional stress or exertion, most common being palpitations, dyspnea, chest pain and syncope.[symptoma.com] In multivariate analysis, the factors significantly associated with an increased risk of VA were syncope (p 0.007), age 7 μg/L (p 0.04), and dobutamine use during hospitalization[ncbi.nlm.nih.gov]

  • Long QT Syndrome

    Penetrance is variable.[nature.com] Patients with syncope following intensive emotional stress should be evaluated for malignant arrhythmias in the context of LQTS.[ncbi.nlm.nih.gov] Syncope in LQTS patients should not automatically be labeled TdP.[ncbi.nlm.nih.gov]

  • Addison's Disease

    Abstract A 19-yr-old intact female variable flying fox ( Pteropus hypomelanus ) presented with lethargy, behavior changes, and substantial weight loss.[doi.org] Signs and symptoms include low blood pressure, nausea and vomiting, syncope, hypoglycemia, hyponatremia, hyperkalemia, a metabolic acidosis, lethergy, confusion, and convulsions[openanesthesia.org] […] following signs and symptoms are usually presented by patients with primary adrenal insufficiency: Anorexia Weight loss Fatigue Muscular weakness Hyperpigmentation Hypotension Syncope[symptoma.com]

  • Septicemia

    This conclusion is supported by the wide variability in hypoglycemia rates reported with protocols [ 205, 206, 207, 212, 213 ].[doi.org] This conclusion is supported by the wide variability in hypoglycemia rates reported with protocols [ 205 – 207, 212, 213 ].[ncbi.nlm.nih.gov] A recent retrospective PICU study reported associations of hyperglycemia, hypoglycemia, and glucose variability with length of stay and mortality rates. [ 331 ] No studies[doi.org]

  • Hypertensive Encephalopathy

    This highly variable prognosis is exemplified by patients that get encephalopathy from hypoglycemia.[medicinenet.com] 肥大型骨関節症 hypertrophic subaortic stenosis 肥大性大動脈弁下狭窄[症] hypertrophy 肥大(厚) hyperuricemia 高尿酸血症 hyperuricemic gout 高尿酸血症性痛風 hyperventilation 過換気、過呼吸、換気亢進 hyperventilation-induced syncope[j-circ.or.jp] 25% in the first 8 hours) 2-1/3 reduction in the first 6-8 hours 3-Not achieving below 95% before 24- 48 hours Excessive reduction leads to diminished cerebral blood flow, syncope[ncbi.nlm.nih.gov]

  • Factitious Hypoglycemia

    The variability of results between point-of-care testing glucose meters and the central laboratory analyzer. Arch Pathol Lab Med. 2006;130:1527-32.[us.bestpractice.bmj.com] The patient was referred to endocrinology to rule out hypoglycemia as the cause of syncopal episodes after a venous fasting blood glucose level of 41 mg/dL was found.[elsevier.es] […] is variable.[en.wikipedia.org]

  • Dumping Syndrome

    In patients with treatment-refractory dumping syndrome, surgical reintervention or continuous enteral feeding can be considered, but the outcomes of such approaches are variable[nature.com] The dizzy spells and syncopal attacks disappeared with dietary adjustment.[ncbi.nlm.nih.gov] A 2-year-old boy, having undergone fundoplication for gastroesophageal reflux disease and fed by gastrostomy, presented with recurrent emesis, syncope with hypoglycemia, and[ncbi.nlm.nih.gov]
