So, genetic and environmental factors affect results at the end. If the person didn't have a healthy lifestyle (well-balances diet and exercise), he or she is definitely more prone to reveal symptoms of diabetes earlier in life. AND alterations in metabolism, such as obesity, act as a trigger to accelerate disruptions in homeostasis.

Thank you for translating that into English
