Symptoms low blood sugar may vary depending on the degree of each episode whether the case is mild or severe. As the level of blood sugar falls, symptoms low blood sugar become more severe. The normal level of blood sugar when fasting or in-between meals is usually within the range of 70 to 110 mg – dl.
Mild low blood sugar or hypoglycemia occurs when the blood sugar level is lower than 65 to 60 mg/dL. In this case, symptoms low blood sugar may include feeling nauseous, extremely hungry, jittery or nervous. Other symptoms low blood sugar for mild cases are sweating, heart palpitations, numbness in the lips or fingertips and trembling.
Moderate low blood sugar or hypoglycemia occurs if the blood sugar level continues to decrease, measuring less than 50 milligrams per deciliter, affecting the nervous system. Symptoms low blood sugar in moderate cases include mood changes and a feeling of weakness, fatigue, dizziness, and drowsiness. The person may also develop poor body coordination and will have difficulty in walking or speaking. Confusion, absent-mindedness and blurred visions are other moderate symptoms low blood sugar.
When blood sugar reaches below 30 milligrams per deciliter, severe symptoms low blood sugar will develop including convulsions or seizures and hypothermia. The person may also lose consciousness and slip into coma. Prolonged case of severe low blood sugar can irreversibly damage the brain and heart, especially in individuals who are already suffering from coronary artery disease.
