Low blood sugar (also known as hypoglycemia) is when blood sugar levels fall below normal. This can lead to a range of symptoms including confusion, clumsiness and loss of consciousness. You may feel hungry, weak, sweaty, shaky, or ill. These symptoms usually appear quickly. Diabetes medications such as insulin or sulfonylureas are the most common causes of hypoglycemia. Diabetes sufferers who eat less than they used to, exercise more than usual, and drink alcohol are at greater risk. Hypoglycemia can also be caused by kidney disease, liver disease, insulinoma, certain tumors, hypothyroidism and starvation. If a baby is not eating for several hours, low blood sugar can occur. Hypoglycemia can be defined by a range of glucose levels. Diagnosis is made for people with diabetes if the glucose level falls below 3.9 mg/l (70 mg/dl). Adults without diabetes are diagnosed if they experience low blood sugar or low blood sugar during symptoms. If blood sugar levels improve, it is considered a diagnosis. A level below 2.8mmol/l (50mg/dl), after eating or exercise, may be used to confirm the diagnosis. Hypoglycemia is a condition in which a newborn's blood sugar level falls below 2.2 mmol/l (30 mg/dl), and lower than 3.3 mg/l (60 mg/dl), if there are symptoms. The blood levels of insulin and C-peptide may also be helpful in diagnosing hypoglycemia. Preventing diabetes is as simple as matching food intake with exercise and medication. A glucose monitor can be used to test for low blood sugar. Low blood sugar may not be apparent at first. This group should be tested regularly. Hypoglycemia can be treated by eating simple sugars and taking dextrose. Insulin or nasal spray may be helpful if the person is unable to eat by mouth. Treatment of hypoglycemia that is not related to diabetes involves treating the underlying condition and eating a healthy diet. Sometimes, the term hypoglycemia is incorrectly used to mean idiopathic posterior syndrome. This condition, which has similar symptoms and occurs after eating but has normal blood sugar levels, is a controversial one. Hypoglycemia refers to a condition where your blood sugar (glucose), is lower than normal. Your body's primary energy source is glucose. Diabetes treatment is often associated with hypoglycemia. Low blood sugar can be caused by other medications and conditions, some of which are rare. When blood sugar levels drop, hypoglycemia must be treated immediately. A fasting glucose level of 70 mg/dL (mg/dL) or 3.9moles/liter (mmol/L) should be considered a warning sign for hypoglycemia. Your numbers may be different. Ask your doctor. The goal of treatment is to quickly get your blood sugar levels back to normal using high-sugar drinks, food, or medications. The long-term treatment of hypoglycemia requires the identification and treatment of the root cause.
