Like type 2 diabetes, developing prediabetes is a growing and concerning trend; affecting around 15% of the population. If not kept in check, it commonly progresses to type 2 diabetes. Certain population groups are at risk, such as African-Caribbean, as are those who experience certain medical conditions, such as gestational diabetes. Although blood sugar levels do not reach the level of type 2 diabetes, living with prediabetes does increase the risk of diabetes complications. Yet, individuals often do not realise that they have the condition. Insulin resistance is present in prediabetes so preventing this from developing means preventing insulin resistance from occurring. Diet and lifestyle can halt the progress of this disease and it can be reversed. Weight loss is key, as is eating a healthy diet, such as the Mediterranean diet. Physical activity can also help to offset prediabetes and this should include resistance training as well as aerobic exercise. It is a growing trend in younger adults not normally associated with developing this condition, and so it is important that prediabetes is identified to prevent the longer term health consequences.
