Whether or not your blood sugar is normal when your fatty liver clears up depends on whether or not the elevated blood sugar is associated with the fatty liver. If it is related, then the fatty liver will recover and the blood sugar will return to normal; if it is not related, then even if the fatty liver is recovered, the blood sugar may not be normal. Clinically, fasting blood glucose higher than 6.1 mmol/L and 2-hour postprandial blood glucose higher than 7.8 mmol/L can be called hyperglycemia. Physiological factors, genetic factors, and certain disease factors can cause hyperglycemia. 1. Physiological factors: common in 1~2 hours after meal. In addition, high sugar diet, short-term strenuous exercise, emotional excitement, etc. can cause a temporary increase in blood glucose. 2. Genetic factors: those with elevated blood glucose in their immediate family have a higher risk of developing hyperglycemia. 3. Certain disease factors: obesity, hepatitis, fatty liver, hyperthyroidism and so on. 4. Other factors: tumors, drugs, stress factors, etc.
