Type-2 diabetes (adult-onset or non-insulin-dependent diabetes) is a common metabolic disorder in which the body is unable to regulate the amount of glucose in the blood. The condition affects nearly 1.5 million people in the UK (Diabetes UK, 2004), and may be undiagnosed in as many as a million more. It develops when insufficient insulin is produced by the body, or when the body's cells no longer respond to insulin (insulin resistance).
The four common symptoms of type-2 diabetes are: excessive thirst, passing large amounts of urine, tiredness and weight loss. Over time, the high blood sugar levels caused by type-2 diabetes causes damage to blood vessels. This leads to atheroma, which can cause problems such as poor circulation, angina, heart attacks and stroke. It can result in diabetic complications, including eye disorders, nerve damage, foot problems, kidney disease and impotence.
The cause of type-2 diabetes is complex, involving an interplay of genes and environmental factors. It tends to occur in people over 40 and is strongly associated with being overweight. Weight loss (plus increased physical activity) is more effective than drug therapy for preventing or delaying the development of type-2 diabetes (Knowler 2002). Stress hormones such as cortisol cause blood glucose to rise and promote insulin resistance (Purnell 2009). Stress may play a role in the development of the metabolic syndrome (Rosmond 2005), which often precedes diabetes, as well as increasing the risk of developing type-2 diabetes itself (Eriksson et al, 2008), and that it can increase the severity of the condition (Oltmans 2006). Depression may contribute to developing the condition (Carnethon 2007).

How acupuncture can help
Chinese medical texts have recognized diabetes as 'wasting-thirsting' for thousands of years, relating it to the consumption of too much rich food. Acupuncture therapy is a common approach to treating diabetes in modern China. However, research is scarce and randomized controlled trials almost non-existent. Most clinical studies have focused on peripheral neuropathy, where there is preliminary evidence for an effect (Jiang 2006; Abuaisha 1998). It may help to treat obesity (Cho 2009), which is the primary risk factor for developing type-2 diabetes, and also depression (see BAcC Fact Sheet 'Acupuncture and Depression').
Studies on physiological mechanisms, both with humans and laboratory animals, indicate that acupuncture may:
regulate insulin production (Lin et al, 2004) and blood sugar levels (Lin 2004; Chang 2006; CabioÄŸlu 2006; Jiang 2006)
improve the blood lipid profile (CabioÄŸlu 2005; Jiang 2006) (dyslipidaemia is common in patients with type-2 diabetes and may lead to cardiovascular morbidity and mortality).
improve blood circulation (Tsuchiya 2007), thus helping to slow the onset and progression of diabetic circulatory complications
moderate the stress response (Sakai 2007)
Most people use acupuncture as part of an integrated diabetes treatment plan because they are already using Western medication. Acupuncture can be safely and effectively combined with Western biomedicine and other treatments such as relaxation exercises and herbal medicine. In addition to offering acupuncture and related therapies, acupuncturists will often make suggestions as to dietary and other lifestyle changes that may be beneficial. Eating a healthy balanced diet, taking regular physical exercise, reducing stress and maintaining a healthy body weight can help to prevent or delay the onset of type-2 diabetes and slow the progression of the disease. Working with a supportive therapist can help people commit to these positive lifestyle changes.
