Symptoms of low blood sugar or hypoglycemia

Hypoglycemia definition, symptoms, cause, treatment

Low blood sugar or hypoglycemia is a condition where glucose level decrease in the blood. 

It turns into a serious condition if not noticed in time. In diabetic patients with insulin are the most vulnerable group for deadly complications.

Definition of low blood sugar or hypoglycemia in people with diabetes, blood glucose of less than 3.9  mmol/L (70  mg/dL). 

Severe hypoglycemia – the need for external assistance to provide glucose, glucagon or other corrective action actively –

Hypoglycemia or low blood sugar symptoms: 

Most common symptoms of hypoglycemia 


 Pounding  heart 


   Speech  difficulty 


  Inability to concentrate 
  In coordination
   Irritability,  anger

in non-diabetic people, it is called ‘spontaneous’ hypoglycemia.

 common causes and risk factors:

 Rapid improvement in and/or strict glycaemic control 
  Previous severe hypoglycemia
  Impaired awareness of hypoglycemia
  Long-duration type 1 diabetes
  Duration of insulin therapy in type 2 diabetes 
 Severe hepatic dysfunction 
  Impaired renal function
  Inadequate treatment of previous hypoglycemia

  Eating  disorder Lifestyle issues
  Irregular  lifestyle 
  Increasing  age 
  Early  pregnancy
  No or inadequate glucose monitoring
  Factitious  (deliberately )

Treatment of hypoglycemia:

  If the patient is conscious and able to swallow: Give oral refined glucose as drink or sweets. Apply glucose gel or jam or honey to the buccal mucosa
 •  Repeat blood glucose measurement after 10–15 mins 

Symptomatic hypoglycaemia (self-treated) :

 it is recommended that all glucose levels  < 4.0  mmol/L (72 mg/dL) are treated. People with diabetes who recognize developing hypoglycemia are encouraged to treat immediately. 

Options available include: 

Oral fast-acting carbohydrate (10–15 g) is taken as glucose drink or tablets or confectionery.
  Repeat capillary glucose measurement 1–15 mins later. If still < 4.0 mmol/L, repeat above treatment
  If blood glucose remains  < 4.0 mmol/L after three cycles (30–45 mins), contact a doctor. Consider glucagon 1 mg IM or 150–200 mL 10% glucose over 15 mins IV 
 Once blood glucose is  > 4.0 mmol/L, take additional long-acting carbohydrate of choice •  

•Unconscious hypoglycemia treatment:

  If the patient is semiconscious or unconscious, parenteral treatment is required: IV 75–100 mL 20% dextrose over 15 mins. Than again check blood sugar.
