What is a hypo?

"Hypoglykämie, often referred to as a 'hypo' is when blood sugar levels are too low, usually below 4 mmol/L," says Douglas Twenefour, deputy head of care at Diabetes UK.

"Low blood sugar can happen if the balance of food consumed, körperliche Aktivität, and diabetes medication taken, such as Insulin or a Sulfonylharnstoffe, isn't right," he explains. "For example, hypos can sometimes happen if you don't consume enough carbohydrates, if you do lots of exercise without having extra carbs or reducing your insulin, or if you take more insulin than you need."

Hypoglycaemia is different from Hyperglykämie, which occurs when you have too much sugar in your bloodstream. This affects people with diabetes whose medication isn't controlling their blood sugar well enough.

Although people can have different symptoms of Hypoglykämie, the most common symptoms of low blood sugar are feeling shaky, sweaty, hungry, disorientated, ängstlich, tired, tearful or irritable.

Someone experiencing a hypo may also go pale and experience Kopfschmerzen, palpitations, a fast pulse or blurred vision, or may find it difficult to concentrate. Sometimes, the lips can feel tingly too. In cases of severe or untreated hypoglycaemia, these symptoms can lead to confusion, impaired Sehen, loss of consciousness, Anfällen or even death.

"Hypos can happen quickly, and there is evidence that regular hypos can be linked to an increased risk of kardiovaskuläre Erkrankungen," says Twenefour. "A severe hypo can lead to death if not treated, so it's important to know how to prevent it, what to look out for, and how to treat it."

"While hypos are less common in those without Diabetes, they can sometimes occur, usually due to other medical conditions or as a result of long periods of fasting, or consuming a lot of alcohol," says Twenefour.

If you don't have diabetes, hypoglycaemia can happen if your body isn't able to stabilise your blood sugar levels. It can also happen after meals if your body produces too much insulin. However, hypoglycaemia in people who don't have diabetes is much less common than hypoglycaemia that occurs in people who have diabetes or related conditions.

"Hypos are the most common side effect of insulin treatment, and are more common in people living with Typ-1-Diabetes - which is managed using insulin - compared to those with Typ 2," adds Twenefour.

There are two types of hypoglycaemia - reactive and non-reactive. Reactive hypoglycaemia occurs when someone experiences low blood glucose levels a few hours after zu essen a meal, due to too much insulin being produced and released.

Non-reactive hypoglycaemia is not directly related to food consumption. It can be caused by certain medications, such as quinine, as well as illnesses involving the liver, kidneys, pancreas or adrenal glands.

It can also be caused by fasting, Alkohol overconsumption, hormonal problems and tumours, which can impact the body's ability to release insulin and lead to low blood sugar levels. Hypoglykämie can also occur among people who have had gastric bypass surgery.

Wenn Sie Diabetes, you can reduce your chance of getting a low blood sugar level if you check your levels regularly when you are taking medication that can cause hypos. Insulin and sulfonylureas are the most commonly prescribed diabetes medicines which can lead to hypoglycaemia.

It's also important to be aware of the symptoms and to carry a sugary snack or drink with you, such as glucose tablets or sweets. You can also prevent hypoglycaemia by eating regular meals and being careful when drinking alcohol.

If you are drinking alcohol, don't consume large amounts, check your blood sugar level regularly and eat a carbohydrate-based snack afterwards. When Sport treiben, eating a carbohydrate snack before exercise can help to reduce the risk of a hypo too.

If you take some types of Diabetes medicine, your doctor may recommend you take a lower dose before or after doing intense Bewegung. It's important to talk to your diabetes care team if you keep experiencing hypoglycaemia.

If you don't have diabetes and think you are getting symptoms of low blood sugar, speak to your doctor so they can try to find out the cause.
