The symptoms, which include :

• Shakiness
• A sense of weakness
• Altered or depressed mood
• Confusion
• Fatigue
• Anxiety
• Paleness
• Perspiration
• Increased pulse or respiratory rate
• Hunger

- typically appear a few hours after eating.

Unlike 'true' hypoglycemia (lack of blood glucose) the syndrome does not lead to damage to the nervous system.

The syndrome is widespread - actual numbers are unknown, but some have described it as 'an epidemic'.

The causes are not currently known.

The are suggestions that the syndrome may not in fact be a 'real' disease. In October 1974, The New England Journal of Medicine featured an article entitled Non-hypoglycemia as an epidemic condition describing the condition as a "non-disease".
