1- Dehydration cause Diabetes

It’s a good idea for everyone to stay hydrated, but it’s especially important if you have diabetes. When your body is low on fluids, the sugar circulating through your blood becomes more concentrated, leading to higher blood sugar levels. Ward off dehydration by drinking plenty of water or zero-calorie beverages throughout the day, but minimize caffeine. Make plain water tastier by adding fresh lemon, lime, or cucumber, or try herbal iced teas.


Caffeine may help you feel more alert, but it can also boost your blood sugar. If you drink coffee, soda, black or green tea, or any other caffeinated beverages, track how they affect your glucose levels and adjust your intake accordingly. Or switch to caffeine-free options.


Stress can trigger the body to release hormones that cause blood sugar to rise, especially in people with type 2 diabetes. You can’t eliminate all stress from your life, but you can learn healthy ways to respond to it and lessen its effects on your body. Removing yourself from stressful situations, learning stress management techniques, and exercising can all help reduce stress. Even just taking a few deep breaths can interrupt your body’s stress response.


A number of prescription and over-the-counter medications can tamper with blood sugar. Cold or sinus medications that have decongestants may cause elevated glucose numbers, and some cold remedies contain alcohol or sugar, both of which you want to avoid.

Lack of Sleep

Not only can a poor night’s sleep leave you groggy and unfocused, it can also increase your blood sugar and decrease your sensitivity to insulin. A study published in 2010 in Diabetes reported that insulin sensitivity was reduced by 20 percent in study participants whose sleep was restricted to just four hours. Try to get a full night of restful sleep; if you have problems falling or staying asleep, talk to your doctor.
