Do You Often Suffer From Low Blood Sugar?

Are you one of those people who often have low blood sugar and need food – now? You are far from alone. But is it really low blood sugar you feel?

There are many who have experienced the feeling that their blood sugar range is falling and as a result have become easily irritated and hungry. Most people have probably heard someone complain about low blood sugar and that they need food – now! The term has been criticized in recent years as a healthy person who does not suffer from diabetes can not get too low blood sugar. By low blood sugar is meant a value below the normal curve 4 – 8.7 mmol / liter.


When studies have made high blood sugar levels measurement on healthy people who often experience that they get low blood sugar, it has not been seen that the blood sugar has been low at the same time. On the other hand, in some cases it has been seen that the symptoms correlate with a decrease in blood sugar within the normal curve. Therefore, it is not really completely wrong to say “I have low blood sugar” as it may actually be a falling blood sugar that the brain tries to raise by signaling hunger and cravings.  


Interestingly, short blood sugar dips below the normal curve can actually be seen in healthy people after a meal. This mainly applies to thin people with high insulin sensitivity and in those who have lost a lot of weight. Even women with moderate overweight on the lower part of the body (buttocks and thighs) have been shown to be sensitive to falling blood sugar after a. A healthy person will raise blood sugar again through the body’s various mechanisms.   


As the brain is dependent on a constant supply of glucose, the body has a number of mechanisms in place when blood sugar begins to fall. The hormone glucagon produced by the pancreas stimulates the release of glucose from stored glycogen in the liver. Glucose can also be formed from lactate (also called lactic acid), glycerol (a component of fat) and glucogenic amino acids (specific amino acids that can be converted to glucose). These mechanisms ensure the risk of developing low blood sugar.

However, a person with diabetes or prediabetes who releases too little insulin or is insulin resistant will not be able to absorb a sufficient amount of glucose. This causes the glucose in the cells to become too low while the glucose present in the bloodstream, the block sugar, becomes too high. It is dangerous with both low and high blood sugar and it has been shown that a relatively high proportion of Sweden’s population is prediabetic.

Obesity, low physical activity, poor diet, stress, smoking and genetics are all factors that affect the risk of developing type 2 diabetes. If you are overweight and experience that your blood sugar monitor  fluctuates frequently, you should therefore measure your blood sugar at a health center. The earlier disorders in the blood sugar regulation are detected, the better it is for the right efforts to be made.  


In most cases where people experience low or high blood sugar levels, it is probably about hunger or cravings. Hunger occurs about every four hours. This corresponds to the time it takes for the stomach to be emptied and nutrients to be absorbed after a meal. An empty stomach will signal to the brain that we are hungry. Falling glycogen levels in the liver, blood sugar and free fatty acids will also affect our hunger.


Regardless of whether your perceived drop in blood sugar range is a falling blood sugar or is due to other signals from the body that say you need food, the dietary advice is the same. Eat nutritious foods that keep you full for a long time and avoid fast energy in the form of sugary foods. Try out how often you need to eat because it is highly individual, although for most people they should be about every four hours. Regular exercise helps you maintain a stable blood sugar and also reduces the risk of type II diabetes.
