Caffeine may impair the function of insulin though may not affect the blood glucose levels among young and healthy adults. The effect of caffeine such as high blood sugar levels may likely be felt by people suffering from type2 diabetes. Caffeine may be present in tea, coffee, cola or energy drinks, cocoa and chocolate. It may affect people physically and emotionally when taken in quantities beyond what the body can process. It is also a kind of a drug that elicits responses just like that of the stress response in the body. However, though people may take the same kind and the same amount of caffeine, the effects may vary depending on the body’s reaction to it.

Young healthy individuals may not have to worry about moderate intake of caffeine but those who have type2 diabetes may have some problems in maintaining normal blood glucose levels. Some studies show that after a large dose of caffeine, blood sugar levels and insulin levels rises among patients with type2 diabetes. The high insulin levels indicate the inefficiency of the body to utilize the hormone to be able to reduce the high glucose level in the blood. Healthy persons would be able to metabolize glucose at about an hour after eating but not for diabetic patients.

For people with diabetes, minimizing caffeine intake may be better if it cannot totally be avoided. Diabetic patients must also be aware that coffee is not the only source of caffeine so it is advisable to read and study labels on food packages and check all ingredients or contents. Caffeine per se does not create blood sugar but it may affect glucose levels in the blood especially when taken together with carbohydrate-rich foods. People’s body reactions to caffeine vary and individuals especially those with diabetes will have to take note about it to help them to be able to keep regular blood glucose levels within range.
