Functional Hypoglycaemia (Low Blood Sugar)

Hypoglycaemia is low blood sugar and ‘functional’ hypoglycaemia occurs when the body is unable to stabilise blood effectively. It often occurs after prolonged periods of stress or anxiety. Women may find that their symptoms worsen before the onset of their periods.

Main symptoms are:

  • Tiredness, vagueness, shakiness that is resolved by eating
  • Tiredness/ irritability first thing in the morning or when hungry
  • Sugar cravings
  • A feeling of being hungry all the time
  • Headaches – relieved by eating
  • Anxiety – relieved by eating
  • Waking at night feeling very hungry

Tiredness and headache are common symptoms of low blood sugar


  • Prolonged stress
  • Diet – over consumption of refined carbohydrates or high alcohol intake


  • Chromium and magnesium are important minerals necessary for controlling blood sugar levels.
  • Chromium is found in whole grains, nuts and cheeses.
  • Magnesium is found in green leafy vegetables, pulses, nuts, wheat germ, whole wheat and oats.
  • Zinc is also important but is only likely to be low in diets that are low in protein. High levels are found in meat, shellfish and poultry, lower levels in pulses, nuts and seeds. Dairy and eggs also contain small amounts.
