How Common Is Low Blood Glucose
Low blood glucose is common among people with type 1 diabetes and among people with type 2 diabetes who take insulin or some other diabetes medicines. In a large global study of people with diabetes who take insulin, 4 in 5 people with type 1 diabetes and nearly half of those with type 2 diabetes reported a low blood sugar event at least once over a 4-week period.2
Severely low blood glucose, defined as when your blood glucose level drops so low you cant treat it yourself, is less common. Among U.S. adults with diabetes who take insulin or some diabetes medicines that help the pancreas release insulin into the blood, 2 in 100 may develop severely low blood glucose each year.3

How To Calculate Your Blood Sugar Level: The Complete Guide
To get an accurate reading of your blood sugar level, the best and most effective method is using a glucose meter. This will involve a small prick in your finger so receive a blood sample. The strip is then inserted into the meter and tested.
You may be wondering what your reading should be. There is no normal reading, an ideal reading differs from person to person. Everyone will get different readings at different times of the day. However, there is a rough range to determining a low, normal and high blood sugar level. Blood sugar level is read in mmol/L, which stands for millimoles per liter. Here is a guide as to what an ideal reading is for each diabetic type and non-diabetic patients:
|4 5.9 mmol/L< 7.8 mmol/L||4 5.9 mmol/L< 7.8 mmol/L|
It is advised to check it regularly if you are concerned, show regular symptoms or have diabetes. You should check before meals, exercise, before bedtime and after driving. Everyone is different so it is best to ask your doctor if you are unsure how many times and when you should check your blood sugar levels.

This may be due to over underlying medical conditions that did not know they had or poor lack of judgement.

When It’s Time To Call A Doctor
If any of the symptoms mentioned have begun to impact your life, such as fatigue so severe you can’t stay awake through the day, it’s a good idea to consult your physician. Dr. Fruge warns that “unstable blood sugar levels could put you at higher risk of heart disease and stroke and it is a red flag for serious health issues” — so blood sugar issues should be taken seriously.
You should also see a doctor if you’re experiencing symptoms of hypoglycemia and haven’t been diagnosed with diabetes or any other underlying condition.
If you do have diabetes and your hypoglycemia isn’t responding to the treatments described above, that’s another good cue to call your health care provider.
If testing reveals you have Type 1 diabetes, you’ll need to continue to test your blood sugar levels as often as instructed by your physician, take insulin regularly and participate in regular exercise. This may mean you will need a new glucose monitoring system, so ask your doctor what they recommend. If you’re diagnosed with Type 2 diabetes, you’ll most likely need to do the same as for Type 1, as well as working with health care professionals to make lifestyle changes such as improving nutrition and planning workouts. Medication may be necessary as well.
Healthy eating, regular exercise and other lifestyle changes can help alleviate symptoms and possibly even reverse prediabetes.

Seeking Treatment For Low Blood Sugar
Since the condition can quickly lead to serious complications, dogs with suspected hypoglycemia should be taken to a vet as soon as possible. Once there, a doctor will perform a physical examination and take note of your dogs symptoms. The next step will be to determine, and ultimately stabilize, your dogs blood sugar levels. This testing is usually done with an instrument called a glucometer, like the FreeStyle Libre.
In some cases, your dogs vet may give your dog glucose or corn syrup orally. For more severe symptoms, dogs may require an intravenous injection of concentrated dextrose, a simple syrup made from corn or wheat. They may also perform further diagnostic tests to monitor your pet for liver disease and check on other organs. Both the length of your dogs stay at the vet clinic and the treatment options available to them will depend on the underlying cause of their condition.
In general, dogs respond quickly to treatment. If overexertion is the cause of their low blood sugar, they may simply need to rest. Getting your dog proper nutrition can also help turn things around. In some cases, though, like with excess insulin in diabetic dogs, an ongoing management plan must be created.
