if diabetes is a high blood sugar level through hyperglycemia?

Question

what condition do you have if your blood sugar level is low?

Answer 1

Hypoglycaemia is a condition where the level of glucose (sugar) in the blood drops below a certain point - about 3.0mmol/l.

This causes a number of symptoms such as dizziness, sweating and fatigue that usually go away 10 to 15 minutes after eating sugar.

What causes hypoglycaemia?

Insulin is normally produced in the pancreas and helps the body's cells absorb glucose from the blood:


After a meal the glucose level rises after a meal to about 7-10mmol/l.


One to two hours later, the glucose level starts dropping again. By the next meal, the glucose level is back to normal: about 4-5mmol/l. The insulin level in the blood has also returned to normal.



Term watch

A 'hypo' is the short name given to episodes of low blood sugar.


Hypoglycaemic episodes (hypos) can be caused by:


over-treatment - the dose of insulin or diabetes tablets is set too high or you accidentally take too much.


mismatched calorie intake versus demand - this happens when your body needs energy but can't get it from your calorie intake ie if you eat less than usual or exercise more.


alcohol - alcoholic drinks tend to lower the blood sugar.


What happens during a hypo?

You can experience some or all of the following symptoms:


Did you know?

Hypoglycaemic episodes are categorised as:
mild - you can manage these episodes alone.
serious - you'll need help from others, such as a family member or doctor.



paleness


shaking


perspiration


a feeling of weakness


rapid heartbeat


hunger


agitation


difficulty concentrating


irritability


fatigue


blurred vision


temporary loss of consciousness


confusion


convulsions


coma.


Most people do get some warning that hypoglycaemia is happening.

But for some, hypoglycaemia may cause few or none of the milder symptoms before the start of sudden unconsciousness or convulsions - particularly if you've had diabetes for many years.


Caution

The aim of diabetes treatment is to have as near normal levels of blood sugar as possible.
Deliberately running higher glucose levels should only be done on a doctor’s advice.


This means loss of consciousness can occur without warning.

To avoid this, you are advised to:


maintain a higher level of glucose in the blood


measure your blood sugar level more frequently.


How is a diagnosis made?

Diagnosis is made by measuring the blood sugar level with a glucose meter.

A glucose level below 3.0mmol/l indicates hypoglycaemia.

Some people experience symptoms when their blood sugar level is higher than this - eg at 4.0mmol/l.

Hypos can't be detected with urine tests for glucose.

How is hypoglycaemia treated?


Did you know?

If you use insulin, your blood sugar level is:
highest 1-2 hours after a meal
lowest 3-4 hours after a meal.



Mild hypoglycaemia is treated by drinking or eating about 10-20g sugar, eg in the form of sweetened juice, milk or glucose tablets.


In the case of a more serious hypo, an ambulance should be called. The paramedic will then give glucose intravenously or glucagon (GlucaGen) (a glucose-increasing hormone) is injected into a muscle.


Your partner and other family members can also be taught to give glucagon injections at home.

A glucagon kit can then be provided so if you suffer several hypos with unconsciousness, immediate treatment is available. In this way, a hospital visit can be avoided.

If you experience hypos repeatedly, you should measure blood sugar level four times a day. This allows you to adjust your insulin and know when you need a snack.

What can I do about hypoglycaemia?


Be familiar with the warning symptoms of hypoglycaemia. This way, you can get treatment quickly. When in doubt, measure your blood sugar levels.


Always carry sugar - preferably glucose in a rapidly-absorbed form such as glucose tablets.


Measure glucose levels regularly. How often depends on your lifestyle - it's something that a combination of practical experience and expert advice will determine. It can vary from one or two readings a week to several readings a day. Knowing how your blood sugar levels change with various activities means you can adjust your level of insulin and minimise the risk of a hypo.


Follow the dietician’s advice and maintain regular eating habits. Some people experience symptoms of a hypo just before a main meal. To avoid this, have snacks between meals to prevent sugar levels dropping too steeply.


Take care when exercising: exercise lowers glucose levels in the blood. You can counter this by taking less insulin than usual beforehand or by eating more before, during or just after exercise.


Carry an identity card that lets others know you have diabetes.


At night

For many people with diabetes, a low blood sugar level during the night is a big problem because you can sleep through it.

If you wake up with a headache and feel unusually irritable, measure your blood sugar at about 3am.

Lower your risk of a hypo by measuring blood sugar at 10pm or 11pm. If it's below 8mmol/l, eat a snack.

Alcohol lowers the blood sugar just like insulin - so avoid alcoholic binges.

After drinking a lot of alcohol or dancing, eat a snack before going to bed.

In the long term

Normally, hypoglycaemia is easily treatable. A few mild episodes in a week are not harmful.

It starts to become dangerous only when the glucose level keeps dropping below acceptable limits - the brain's only source of energy is glucose.

Answer 4

I am writing to tell you what an incredible impact these methods had on my life! I have had type 2 diabetes for 27 years. For me, the worst part of this horrible disease is the severe pain I constantly get in my feet. The pain is so bad that I avoid standing and walking as much as possible. I've got to tell you that within the first month, my feet stopped hurting altogether and I can now walk totally pain free.

Believe it or not, I even danced at my niece's wedding last month, something I have not done in a many years. I've been following the book for six months now and my blood sugar is well within normal range. I feel great!

I recommend you use the Type 2 Diabetes Destroyer to naturally reverse your diabetes.

Answer 5

Diabetes is the name of the condition in which your pancreas can no longer produce enough insulin to maintain the body's blood sugar levels.

Hyperglycaemia (high blood sugar) and hypoglycaemia (low blood sugar) are the symptoms of diabetes.

Low blood sugar occurs if a diabetic person fails to eat properly, takes too much insulin, or takes insulin and forgets to eat.

High blood sugar would occur if the diabetic person forgets to take insulin or does not take enough, then eats.

I am talking about type 2 diabetes here.

Answer 6

Hypoglycemia is the medical term for low blood sugar and it is more dangerous to have low blood sugar as sugar is what makes your cells work. In the long term Diabetes is bad but in a short term low blood sugar can kill quickly.

Answer 7

Many common natural remedies are claimed to have blood sugar lowering properties that make them useful for people with or at high risk of diabetes. Learn here https://tr.im/m1P3q

A number of clinical studies have been carried out in recent years that show potential links between herbal therapies and improved blood glucose control, which has led to an increase in people with diabetes using these more 'natural' ingredients to help manage their condition.

Answer 8

Low blood sugar is called hypoglycemia. It is most commonly caused by the medication diabetics take. It can occur in some people who have no real disease, if they go to long between meals, especially if they use up sugar by vigorous activity.
There is also a rare pancreatic tumour that cause it by inappropriately secreting insulin.

The first sentance in your question does not quite make sense so I hope my answer includes the information you wanted.

Answer 9

Hypoglycemia-low blood sugar. Needing to eat 5-6 small meals per day, proteins, carbs, etc. to keep the blood sugar level UP to a normal level. A person with hypoglycemia needs to follow the instructions of their dr., and nutritionist.

Answer 10

hypoglycemia - that means your blood sugar is too low, eg. because you produce too much insulin. People with diabetes (type 1 or type 2 on certian treatmets) can suffer from hypoglycemia if we take too much insulin relitive to what we've eaten - this is why people with diabetes sometimes need sugary things like lucozade or glucose tablets or chocolate bars!
