reactive hypoglycaemia
dietary changes
Reactive hypoglycaemia (RH) is often successfully treated with dietary changes.[44]Kandaswamy L, Raghavan R, Pappachan JM. Spontaneous hypoglycemia: diagnostic evaluation and management. Endocrine. 2016 Jul;53(1):47-57. http://www.ncbi.nlm.nih.gov/pubmed/26951054?tool=bestpractice.com The diet should be high in proteins and low in carbohydrates, with frequent but smaller feeds to avoid the big fluctuations in the insulin secretion from the pancreas.[51]Kabadi UM, Kabadi MU. Idiopathic reactive hypoglycemia: resolution on increased protein intake secondary to decreased insulin response with enhanced glucagon rise. Endocrine Society Annual Meeting, page 540, abstract no. P2-568. Chevy Chase, MD: Endocrine Society; 2006.[52]Ahmadpour S, Kabadi UM. Pancreatic alpha-cell function in idiopathic reactive hypoglycemia. Metabolism. 1997 Jun;46(6):639-43. http://www.ncbi.nlm.nih.gov/pubmed/9186298?tool=bestpractice.com [53]Khan M, Kabadi UM. Postprandial hypoglycemia. In: Rigobelo EC, ed. Diabetes - damages and treatments. Rijeka, Croatia: InTech Open; 2011:117-26. http://www.intechopen.com/books/diabetes-damages-and-treatments/postprandial-hypoglycemia A high-fibre diet or fibre supplementation is also recommended to prevent RH.[54]Sørensen M, Johansen OE. Idiopathic reactive hypoglycaemia - prevalence and effect of fibre on glucose excursions. Scand J Clin Lab Invest. 2010 Oct;70(6):385-91. http://www.ncbi.nlm.nih.gov/pubmed/20509823?tool=bestpractice.com
exposure/overdose medication, toxin, ethanol
supportive care ± psychiatric evaluation and treatment
All patients may require supportive care with glucose and/or glucagon. Those exposed to offending medication/toxin or exogenous insulin/sulfonylurea may require inpatient monitoring and glucose infusion until the effects diminish; timeframe is variable.
Options include D10 or D50 infusion or glycogen infusion or injection, closely monitored with frequent blood glucose checks or, as glucose stabilises in the normal range, glucometer readings. The aim is to monitor for sustained hypoglycaemia and prompt correction.
If intentional overdosing of salicylates, ethanol, insulin, or sulfonylureas is suspected, the patient should be screened to determine whether referral to a psychiatric speciality is warranted.
If suicidality is present, involuntary commitment may be necessary.
bariatric surgery, anorexia, malnutrition, ackee fruit ingestion
supportive care ± referral to specialist
In addition to correcting the glucose deficiency by supportive care with glucose and/or glucagon, referral or consultation with endocrinology, toxicology, or gastrointestinal disease specialists may be necessary in these patients.
insulinoma
surgical excision
If hypoglycaemic events continue after surgery, consideration should be given to repeating surgery to look for incomplete excision of primary tumour or rare malignant transformation with metastases.[7]Service FJ, McMahon MM, O'Brien PC, et al. Functioning insulinoma - incidence, recurrence and long term survival of patients: a 60 year study. Mayo Clin Proc. 1991 Jul;66(7):711-9. http://www.ncbi.nlm.nih.gov/pubmed/1677058?tool=bestpractice.com
supportive care
Treatment recommended for ALL patients in selected patient group
Supportive care while awaiting surgery may include self-administered glucagon injections.
medical therapy
For those who fail surgery or who are not surgical candidates, these pharmacological agents may be used to control hypoglycaemia for a period of time.
Primary options
diazoxide: 3-8 mg/kg/day orally given in 2-3 divided doses
OR
octreotide: 50 micrograms subcutaneously twice to three times daily
OR
streptozocin: refer to consultant for guidance on dosage
supportive care
Treatment recommended for ALL patients in selected patient group
All patients may require supportive care to maintain their blood glucose levels while awaiting definitive therapy.[46]De Buck E, Borra V, Carlson JN, et al. First aid glucose administration routes for symptomatic hypoglycaemia. Cochrane Database Syst Rev. 2019 Apr 11;(4):CD013283. https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013283.pub2/full http://www.ncbi.nlm.nih.gov/pubmed/30973639?tool=bestpractice.com Options include D10 or D50 infusion or glycogen infusion or injection, closely monitored with frequent blood glucose checks or, as glucose stabilises in the normal range, glucometer readings. The aim is to monitor for sustained hypoglycaemia and prompt correction.
focal embolisation or chemotherapy
Treatment recommended for ALL patients in selected patient group
If hypoglycaemic events continue after surgery, one possibility is rare malignant transformation with metastases.[7]Service FJ, McMahon MM, O'Brien PC, et al. Functioning insulinoma - incidence, recurrence and long term survival of patients: a 60 year study. Mayo Clin Proc. 1991 Jul;66(7):711-9. http://www.ncbi.nlm.nih.gov/pubmed/1677058?tool=bestpractice.com
Focal embolisation or chemotherapy may be required for metastatic disease.[47]Stephen AE, Hodin RA. Neuroendocrine tumors of the pancreas, excluding gastrinoma. Surg Oncol Clin North Am. 2006 Jul;15(3):497-510. http://www.ncbi.nlm.nih.gov/pubmed/16882494?tool=bestpractice.com
IGF-II-secreting tumour
surgical excision ± chemotherapy/radiotherapy
The patient with insulin-like growth factor (IGF)-II hypersecretion should be referred to a surgeon for excision of the offending mass.
Therapies that reduce tumour burden (e.g., chemotherapy, radiotherapy) may help to relieve symptoms in some cases.[44]Kandaswamy L, Raghavan R, Pappachan JM. Spontaneous hypoglycemia: diagnostic evaluation and management. Endocrine. 2016 Jul;53(1):47-57. http://www.ncbi.nlm.nih.gov/pubmed/26951054?tool=bestpractice.com
supportive care
Treatment recommended for ALL patients in selected patient group
While awaiting surgery, glucose levels may need to be supported with intermittent glucose infusion or glucagon administration.
renal failure, liver failure, sepsis, or other endocrinopathy
management of underlying condition
Mainstay of therapy in these aetiologies of hypoglycaemia is management of the underlying condition, with supportive therapies to maintain adequate blood glucose level.
supportive care
Treatment recommended for ALL patients in selected patient group
Support with glucose infusion may be necessary until the condition resolves, especially if the patient cannot tolerate oral intake.
