Managing diabetes involves keeping your blood sugar levels within a healthy range. High blood sugar (hyperglycemia) can occur when you consume too many carbohydrates, miss your medication, or reduce physical activity. Stress and certain medications can also raise blood sugar levels. Symptoms include frequent urination, fatigue, and increased thirst. Low blood sugar (hypoglycemia) happens when you don't eat enough or exercise too much. Symptoms include sweating, shaking, and confusion. To manage blood sugar, monitor it regularly using a glucose meter. The American Diabetes Association recommends testing at least four times a day if you're on insulin. Continuous glucose monitors can also help. For high blood sugar, adjust your diet, medication, and activity levels. For low blood sugar, follow the 15-15 Rule: consume 15 grams of carbs, wait 15 minutes, and recheck your levels. Always consult your doctor for personalized advice.
