Severe Hypoglycemia symptoms are very serious and can be life threatening. People with diabetes who have a history of episodes of hypoglycemia should carry glucose tablets or injectable glucagon (glucocorticoid) on hand in case they have an episode.
Symptoms of Hypoglycemia
When the blood sugar level is low, it can be difficult to think clearly and perform everyday tasks. It can also affect your mood and cause you to feel tired or depressed.
Your doctor may check your blood sugar by doing a fasting test or a mixed-meal tolerance test. This test can help to determine if your symptoms are caused by hypoglycemia or another condition.
You can also check your blood sugar by doing a self-monitoring blood glucose test. This is an inexpensive test that allows you to know your blood sugar levels and see how they change when you eat or drink different foods.
If you are concerned about your symptoms, talk to a healthcare provider or call 911 immediately. The sooner you get help, the better the chances are that your symptoms will be less severe and you can continue with your normal daily activities.
Symptoms of Hypoglycemia that aren’t treated can be life-threatening, especially in people with type 1 or type 2 diabetes. They can lead to a coma or death.
The best way to prevent or treat hypoglycemia is to monitor your blood sugar regularly and adjust your treatment plan if you have frequent episodes. It is also important to understand your personal warning signs and make sure you keep a symptom diary so you can track your symptoms and how long they last.

Your healthcare team can recommend treatments that will bring your blood sugar back to a healthy level. These may include eating a sugary snack or taking an oral medication.
You should avoid eating or drinking too much alcohol if you have a history of episodes of hypoglycemia. Excessive alcohol consumption can inhibit the liver’s ability to release glucose from its glycogen stores into the bloodstream.
Other medications can also cause hypoglycemia, especially in children and people with kidney failure. Medications such as pentamidine and quinine can reduce the amount of glucagon your body produces and may cause an episode of hypoglycemia.
When you have an episode of severe hypoglycemia, your doctor may give you a shot or inhaler of the hormone glucagon to raise your blood sugar level and restore consciousness. If you have a family member or other person with you who is trained in using the injection, they can help administer it to you.
A glucagon kit can be purchased from your local health department. This kit contains several types of glucagon and other necessary supplies, such as an injection site and an injectable device.
The glucagon can be used on its own or in combination with other medicines. If you have a severe episode of hypoglycemia, call your doctor right away and ask them to prescribe a glucagon injection.
