When something is not right for the body, it sends some signals after which we can recognize if there is a problem. Discomforts and consequences are the body’s process designed to tell all of us that there is a problem. In the case of having high glucose (sugar) levels in the blood, it is an indicator that your pancreas is not working as it should, and requires quick attention, thus reducing the complications that a blood glucose level can bring. not controlled .

Blood generally has sugars such as carbohydrates and glucose, and this glucose offers vitality to the organs and cells of the body. To keep the amount of sugar in a regular range, the body needs insulin. Insulin is the body’s hormone that delivers sugar to body tissues. In a person with type 1 diabetes, the tissues in the pancreas that produce insulin are affected. In people who have type 2 diabetic disease, their bodies make insulin, but they cannot use it normally.

Signs of very high blood sugar levels

Once blood sugar levels rise, they start to cause problems. Blood vessels end up damaged and can lead to many problems. It can trigger kidney disease, stroke, or even vision loss, among many other chronic injuries or conditions.

The rapid diagnosis of high blood sugar levels will help you prevent these consequences and many other conditions that can even be fatal, if you do not keep a rigorous glucose control.

1. Tingling and burning

High amounts of glucose can cause chills in the feet, hips and legs and fingers, you can feel a tingling sensation and not being able to keep your legs still, it looks like restless legs syndrome . This symptom is created by nerves damaged by diabetes (neuropathy), one of the consequences of diabetic disease.

2. Constant hunger

Without adequate blood glucose levels to support the vitality of the body, you may feel the urge to eat and never feel full. This leads to blood sugar levels continuing to rise, making the situation worse.

3. Very frequent urination

The average person generally has to urinate four to seven times in 24 hours, but people with diabetes can urinate much more.

Why does this happen? Normally, the body reabsorbs glucose as it passes through the kidneys. But when the level of sugar in the blood rises , the kidneys may not be able to return it all, this causes the body to produce more urine, and that requires fluids.

You will have to go to urinate more often . Because you are urinating a lot, you may be very thirsty. When you drink more, you also urinate more, and although you appear well hydrated, your mouth will be dry and your skin may itch.

4. Very thirsty

High levels of blood sugar and urine are responsible for the prolonged feeling of thirst, which is not even satiated even if several glasses of water are drunk in a row.If this is your case, it is an unequivocal sign that you need to consult a specialist as soon as possible.

5. Weight loss or gain for no reason

Once the cells of the body do not obtain the necessary sugar, the body burns the fat and the vitality of the muscle. It can lead to unusual or unexpected weight loss and weight gain. Although weight loss can be due to various causes, it is advisable to measure blood sugar levels as soon as possible.

6. Exhaustion and lethargy

Your body converts the food you eat into glucose, which your cells use for energy. But cells need insulin to carry glucose, and when your body doesn’t make enough insulin or if your cells resist the insulin your body makes, glucose can’t get into them and you don’t have energy. This can make you feel hungrier and more tired than usual.

7. Difficulty concentrating

Once the body is out of balance, the mind also suffers from these symptoms. High sugar levels can cause memory problems and problems to focus on a specific task, causing stress and frustration in those who suffer from it.

8- Difficulty healing wounds

High amounts of glucose damage nerve fibers. If injuries such as cuts or bumps are slow to heal, you should monitor your blood sugar level.

9. Blurred vision and instability

Obstructed view and instability should not be ignored in any way, especially if they happened suddenly. Higher sugar levels can be a reason behind them, but although it can happen from one moment to another, for the eyes to be affected, it has had to suffer for a long period of changes in blood glucose.

10. Nausea and vomiting

When the body turns to burning fat, it produces “ketones.” These can accumulate in the blood to dangerous levels, a potentially fatal condition called  diabetic ketoacidosis.  Ketones can make you feel very sick to your stomach.

Below, you will find an illustrative video on the optimal glucose levels for the body in a healthy person. Fasting glucose levels and postprandial glucose levels (2 hours after meals) are displayed .
