Will these surprising factors really raise your blood sugar?

The Internet contains many claims about factors that increase blood sugar. Some, however, just don’t hold up. For example, stress from sunburn pain, not drinking enough water, and using steroid nasal sprays will not make blood sugar spike. Likewise, it’s unclear if caffeinated coffee, artificial sweeteners, or gum disease will increase blood sugar. However, it is well established that some factors do raise blood sugar over time, such as overeating, a sedentary lifestyle, and obesity.
