Blood sugar imbalances, particularly hypoglycaemia and diabetes, have reached epidemic levels in the UK and most Western countries due to poor diet, sedentary lifestyles, chronic stress, and rising obesity. Hypoglycaemia causes fatigue, irritability, and dizziness from low blood sugar, while diabetes results from impaired insulin function, leading to persistently high glucose levels and long-term complications such as cardiovascular disease, kidney damage, and neuropathy. The prevalence is fuelled by processed foods, excessive sugar intake, and modern lifestyle patterns. Addressing these epidemics requires education, early detection, lifestyle changes, and integrative medical approaches to restore balance and prevent disease progression.
