You don’t have to have prediabetes or diabetes to worry about your blood sugar levels. Unbalanced levels can affect how you feel on a daily basis, and meal separately.
“When blood sugar is poorly regulated after a carbohydrate-rich meal, snack, or sugary drink, a person may develop post-meal fatigue, mood swings, or even more cravings,” Crouch says. “When this happens, it’s because the insulin response is overshooting, causing sugars to drop too little which leads to cravings for sweets to raise blood sugar again. This becomes a vicious cycle that can lead to decreased insulin sensitivity.”
Crouch says a healthy blood sugar is one of no more than 140 mg/dL after meals and drops to less than 100 mg/dL about two to three hours after eating. You won’t know these numbers if you don’t get a lab or use a glucose monitor, but prolonged high blood sugar has some specific symptoms.
Vision may be blurry, excessive thirst, getting up to urinate frequently at night, unintended weight loss, mood swings, and brain fog. Signs that your blood sugar levels are irregular.
