Understanding What Causes Type 2 Diabetes
If you want to reverse diabetes, and not just manage symptoms with meds, then you need to uncover and address the root cause(s).
The challenge is that these causes are not always clear-cut, as it varies for each person. T2D is always caused by a combination of family history, lifestyle choices, and even environmental factors.
Family History
Diabetes can run in families. If your parents or grandparents have it, you might have a higher chance of developing it too. Scientists have identified more than 36 genes that can increase the risk of diabetes. For example, a gene called TCF7L2 significantly raises the risk, making it worthwhile to check if you have it. Most diabetes-related genes affect how the pancreas produces insulin. While having a genetic predisposition can be a challenge, it does not mean diabetes is inevitable.
Lifestyle Choices
The way we live can also contribute to diabetes. Some key lifestyle factors that can increase the risk include:
Eating ultra-processed foods and not enough protein: Consuming too many calories from junk food, such as sugary drinks and cereals, can lead to weight gain because you’re hungry all the time. Being overweight makes it harder for the body to use insulin effectively.
Lack of strength-training: Lack of muscle mass can reduce how well the body processes sugar, causing it to remain in the blood or be stored as fat.
Excessive Alcohol Consumption: Drinking too much alcohol can increase diabetes risk through several mechanisms, including excess calorie intake, fatty liver, and blood sugar spikes.
Environment and Socioeconomic Factors
Where we live and our financial situation can significantly impact our health. Some people may not have access to healthy foods or safe places to exercise, making it more challenging to prevent diabetes.
Recent Findings
New studies are providing more insights into how diabetes develops:
Fat in Organs: Excess fat in the liver and pancreas can make it difficult for the body to regulate blood sugar. This concept, known as the personal fat threshold, explains why someone who is 6’ and 300 lbs may not have diabetes, while another person who is 6’ and 200 lbs might.
Low Testosterone: There is a direct link between low testosterone and high blood sugar. It’s a "chicken and egg" situation, meaning both issues need to be addressed together for effective management.
Conclusion
Understanding what causes type 2 diabetes can empower us to make better lifestyle choices and even reverse the disease. Eating healthier, staying active, and being aware of family history can all help in prevention and management.
