Early warning signs and symptomsEarly signs and symptoms of diabetic hypoglycemia include:
- Shakiness
- Dizziness
- Sweating
- Hunger
- Irritability or moodiness
- Anxiety or nervousness
- Headache
Nighttime Symptoms
- Diabetic hypoglycemia can also occur while you sleep. Signs and symptoms, which can awaken you, include:
- Damp sheets or bedclothes due to perspiration
- Nightmares
- Tiredness, irritability or confusion upon waking
Severe Symptoms
If diabetic hypoglycemia goes untreated, signs and symptoms of severe hypoglycemia can occur. These include:
- Clumsiness or jerky movements
- Muscle weakness
- Difficulty speaking or slurred speech
- Blurry or double vision
- Drowsiness
- Confusion
- Convulsions or seizures
- Unconsciousness
- Death
Take your symptoms seriously. Diabetic hypoglycemia can increase the risk of serious — even deadly — accidents. Identifying and correcting the factors contributing to hypoglycemia, such as medications you take or irregular mealtimes, can prevent serious complications.Informing people you trust, such as family, friends and co-workers, about hypoglycemia is important. Their knowing what symptoms to look for and what to do in case you`re not able to help yourself can make a potentially difficult situation easier to manage. It`s also important that they know how to give you a glucagon injection, in case it becomes necessary. Symptoms can differ from person to person or from time to time, so it`s important to monitor your blood sugar levels regularly and keep track of how you`re feeling when your blood sugar is low. Some people don`t have or don`t recognize early symptoms (hypoglycemia unawareness). If you have hypoglycemia unawareness, you may require a higher glucose goal range.
When to see a doctor?
Hypoglycemia can leave you confused or even unconscious, which requires emergency care. Make sure your family, friends and co-workers know what to do.If you lose consciousness or can`t swallow:
- You shouldn`t be given fluids or food, which could cause choking
- You need an injection of glucagon — a hormone that stimulates the release of sugar into the blood
- You need emergency treatment in a hospital if a glucagon injection isn`t on hand
If you have symptoms of hypoglycemia several times a week, see your doctor. You may need to change your medication or your dosage or otherwise adjust your diabetes treatment program.
Hypoglycemia is most common among people who take insulin, but it can also occur if you`re taking certain oral diabetes medications. Common causes of diabetic hypoglycemia include:
- Taking too much insulin or diabetes medication
- Not eating enough
- Postponing or skipping a meal or snack Increasing exercise or physical activity without eating more or adjusting your medications
- Drinking alcohol
Blood Sugar Regulation
The hormone insulin lowers glucose levels when glucose is elevated. If you have type 1 or type 2 diabetes and need insulin to control your blood sugar, taking more insulin than you need can cause your blood sugar level to drop too low and result in hypoglycemia. Hypoglycemia also may result if, after taking your diabetes medication, you eat less than usual or exercise more than you normally do. Your doctor can work with you to prevent this imbalance by finding the dose that fits your regular eating and activity patterns.
If you ignore the symptoms of hypoglycemia too long, you may lose consciousness. That`s because your brain needs glucose to function. Recognize the signs and symptoms of hypoglycemia early because if untreated, hypoglycemia can lead to:
- Seizures
- Loss of consciousness
- Death
On the other hand, be careful not to overtreat your low blood sugar. If you do, you may cause your blood sugar level to rise too high (hyperglycemia), which can become a problem with repeated episodes of hypoglycemia.
