There are two main reasons for the morning rise in blood sugar levels – the phenomenon of dawn and the effect of Somoji. Consider both reasons, tell you what risk factors can cause a poor feeling in the morning, and also give practical advice on how to better manage blood sugar.
The phenomenon of dawn is associated with natural changes in the body that occur during sleep.
Midnight – 3 am
At this time, the human body does not need insulin. However, any insulin that may have been received during the evening causes a sharp drop in blood sugar levels.
Between 3 and 8 am
The body automatically begins to store sugar (glucose) for the upcoming day. Besides, hormones are released, which actively reduce the body’s insulin sensitivity.
During this period, counterregulatory hormones are released, which can interfere with insulin production, which leads to an increase in blood sugar levels.
Growth hormones are counter-regulating hormones., such as:
When all these processes occur simultaneously, during sleep, the insulin level begins to decrease. However, each of these processes ultimately plays a role in raising blood sugar levels at dawn or in the morning.
Who is affected by the dawn phenomenon?
Although people with diabetes are usually more aware of the dawn phenomenon, it can happen to anyone. Anyway, this phenomenon has a different effect on those who have diabetes and those who do not.
Usually, people who do not have diabetes usually do not notice high blood sugar levels in the morning. This is explained by the fact that insulin in the body regulates the level of sugar, without leaving an excess of glucose in the blood.
And vice versa, people with diabetes can’t control insulin levels. As a result, they often experience an increase in fasting blood sugar.
However, the effect of the phenomenon of dawn is individual. There are no people who react equally to this phenomenon.
Another cause of high blood sugar in the morning can be Somogia effect or chronic insulin overdose syndrome.
The effect of Somodzhi is not as common as the dawn phenomenon. It is named after the researcher who discovered it – Michael Somoji.
The causes of high blood sugar levels in the morning are the same for both the dawn phenomenon and the Somoggia effect.
Exists One major difference between these two phenomena:
- The phenomenon of dawn occurs naturally
- Somodja effect results from poor diabetes control
Usually, the reasons are late taking insulin or skipping meals or snacking. There are two scenarios that can affect the Somoggia effect:
- Too much insulin or not enough food before bedtime. At night, blood sugar levels may drop too low. The body reacts, releasing hormones that should raise it.
- Insufficient insulin dose in the evening. In some cases, the insulin dose may not be sufficient for a person, and as a result, in the morning he wakes up with high blood sugar.
The test for the phenomenon of dawn and the effect of Somodzhi
Since the phenomenon of dawn and the effect of Somodzhi are very similar, it is important that the doctor correctly identifies the cause of high blood sugar levels in the morning.
Usually, doctors begin by checking blood sugar levels for several nights in a row, between 2-3 in the morning. Perfect for this process. continuous monitoring of blood glucose, but you can use a normal blood glucose meter.
If a Human blood sugar is defined as low, it is usually considered a sign of the Somoggia effect. If when testing the blood sugar level is normal or constantly high; it most likely speaks of the dawn phenomenon.
The treatment of the dawn phenomenon largely depends on how high the insulin levels are. there is a few points that a doctor can recommend, including:
- Refusal to consume large amounts of carbohydrates before bedtime
- The correct calculation of the dose of insulin or another diabetic drug
- Switching to another drug
- Changing the evening time for long-acting insulin
- Using an insulin pump that helps regulate insulin dosage
Some of the points can be used to treat both the Somoggia effect and the dawn phenomenon. However, some recommendations for people experiencing the effect of Somoggia, are different. These include:
- Carbohydrate snack a few hours before bedtime
- Consultation with a doctor about reducing the dose of sugar-reducing drugs in the evening
- Reducing the dose of long-acting insulin
For most people, the phenomenon of dawn is short-lived and does not cause additional problems. For people who experience a slight increase in blood sugar levels in the morning, this phenomenon usually disappears with time.
Effect of insulin resistance
Some people are more resistant to insulin in the morning. In such cases, it is recommended to limit carbohydrate intake in the first few hours after waking up.
If you continue to eat carbohydrates in the morning, your blood sugar levels may continue to rise. Thus, high blood sugar levels can last for quite a long period of time. This process should be monitored, because it is dangerous to health. In such cases, it is necessary consult a doctor who will help you adjust your meal schedule and find the right treatment.
Effect of hormonal changes
If you ignore the effect of Somodzhi, complications may occur over time. Since the hormones in our body are constantly changing, the human response to low blood sugar levels may also change. This can lead to the fact that the body is not able to properly adapt to low sugar levels.
Even if you do not notice any symptoms, the body may not cope with the situation and stop giving liver signals about the release of sugar into the blood.
What is important to remember
It is important to remember how the dawn phenomenon and the Somoji effect appear., so that people who experience this will seek treatment in time.
Those who have a high blood sugar level for too long are at risk of developing other diseases, such as heart diseases and stroke. Constant monitoring and proper management of blood sugar jumps are crucial in the healing process.
