###Human: Why does my blood sugar level go up even without doing anything? ###Assistant: Hi Thanks for your query It’s good to see ur sugars are good with HBA1c 6.4. Blood sugars go up and down not only with meals but there are many other factors associated as well like other Harmon levels in the body. For example if ur stressed mentally or excited ur cortisol and catecholamines also increase and thus may lead to increase sugar levels as well Same way if u will do exercise it will decrease ur sugar as well as use of alcohol. May be ur eating habits didn’t change much but other factors have something to do with these levels.  Sleep is also important. Along with medications I always advise for intermittent fasting and low carbohydrates with least grains. Exercise even if it’s just walking 45 minutes daily is beneficial Thanks
