Do you know how high your blood sugar is? If your blood contains more sugar than normal after a full night of sleep and no breakfast, you may be considered prediabetic, a step toward type 2 diabetes.
Prediabetes is a condition that is closely linked to mental health problems. Research in the United Kingdom has found that high blood sugar may play a role in cognitive decline even before type 2 diabetes develops.
STUDIES
Scientists at the University College London (UCL) analyzed data from 500,000 people with an average age of 58. They found that people with prediabetes had a 42% increased chance of cognitive decline over four years. In this group, vascular dementia – caused by reduced blood flow to the brain – increased by 54%.
Even after accounting for age, low socioeconomic status, smoking, body mass index, and cardiovascular disease, these rates remained high. The researchers can't say for sure that high blood sugar causes these brain diseases because the study was observational, not a clinical trial. But given the strong evidence that diabetes increases the risk of dementia and cognitive problems, the link is plausible.
Next steps
The UCL study is unique because the link between prediabetes and cognitive decline has not been previously assessed. To better clarify these links, additional data from a larger group of people needs to be analyzed. If the links are confirmed, the researchers will develop a clinical trial to understand the exact mechanisms.
Chronic high blood sugar is linked to poor blood clotting, and vascular dementia is caused by inadequate blood flow to certain parts of the brain. In prediabetes and diabetes, the blood becomes more viscous and sticky, preventing the transport of necessary nutrients and oxygen to parts of the brain that are supplied by small blood vessels. The condition of prediabetes is reversible, so there is no reason to wait for further clarification.
What can you do about high blood sugar?
Dietary and lifestyle changes are the best way to lower high blood sugar. Eliminate processed, sugary, nutrient-poor foods. Eat whole, natural foods, and don't be afraid of natural fats.
Intermittent fasting can be a simple option, but make sure you're getting enough nutrients, including protein. Focus on nutrients, not calories. Exercise regularly, even if it's just a short walk; 150 minutes of exercise per week is recommended. Stay outside, get some sunlight every day, and prioritize sleep, which boosts your metabolism and reduces cravings for junk food.
Prediabetes is a condition associated with high blood sugar and may be linked to cognitive decline. This doesn't necessarily mean it causes it, but diet and lifestyle advice is helpful for everyone. Ultimately, improving your diet and physical activity can reduce your risk and improve your health and quality of life.
