Why does the high blood sugar level cause you to be sleepy? Is sleeping through meals or the wrong food a sign that you have diabetes?’ Diabetic and pre-diabetic patients often ask these concerns. Patients want to learn about the effect the sugar has on their sleep routines.


In this article, we’ve examined whether sugar is a factor that causes your sleep and the connection of this issue with the condition known as Diabetes Mellitus.

Many people start feeling exhausted after having their meals. The habit of sleeping after meals has become the norm for a lot of people. While some think it’s an acceptable practice, others say this could pose a severe indication of diabetes.


Knowing the science behind the subject is essential to determine if the practice is a suitable or risky activity.

We will also discuss the research behind sleep after eating and the benefits of this method, the risk of developing diabetes, as well as how to go to sleep safely.


Why is it that the blood sugar level rise makes you feel sleepy?

Many people might have heard of the expression “sugar can make people tired. But, the majority of them should be aware of the reason that causes it. In the event that we consume sugar, the body releases insulin in order to control the blood sugar level. It is a hormone that lets cells absorb glucose from the bloodstream to provide energy.


However, it is true that when we consume a large amount of sugar, our body can produce more insulin than required, which could cause glucose levels in the blood to decrease quickly.


An abrupt decrease in blood sugar could cause feelings of fatigue and lethargy, often called”the ” sugar crash.” In addition, excessive consumption of sugar can result in the body’s innate inflammation, as well as stress within the body, which could create a feeling of exhaustion and lower energy levels.


In addition, eating sugar prior to going to sleep can alter the sleep pattern, which can cause tiredness and drowsiness later in the day. Sugar consumption can trigger an increase in blood sugar levels, which can interfere by releasing hormones that induce sleep, like the hormone melatonin.

The disruption in the sleep-wake cycle could cause daytime drowsiness as well as decreased cognitive function.


The science behind sleeping when you eat

After eating, our bodies begin the digestion processes in which they break down foods into small molecules that the bloodstream is able to absorb. Digestive enzymes, along with other substances in our intestines and stomach, aid in this process. After the bloodstream takes them, they are delivered to our cells, which are utilized to generate energy and also to maintain and repair the tissues of our body.

Sleep is an important moment when our bodies are able to heal and rebuild themselves. While we sleep, the body releases hormones that encourage the growth of tissues and repair and strengthen our immune system. is also more active to fight off infection and other dangers.


However, when we go to sleep right following eating, the body needs to divide its resources between repair and digestion, which can disrupt both of these processes.

Many factors influence the effects of sleeping following eating. The kind of food we consume can affect the speed at which it is taken in and digested. For instance, food items that are high in protein and fat are more difficult to digest than carbs, which slows the digestion process.


Furthermore, the level of activity we have after eating may affect the way our bodies digest food. Simple activities such as walking can aid in digestion and lessen discomfort. Asleep or lying down may delay the process and result in pain.


Sleeping in a safe environment is a good habit to avoid after eating.

Although it is widely thought that a night of sleep after eating may disrupt the digestion process, research has proven that there could be benefits to this routine. One of the significant benefits is improved digestion.


While we sleep and our bodies rest, they can concentrate on healing and restoring cells. This will aid in supporting the digestive process. The digestion process is improved and could be enhanced by giving our bodies the ability to focus on restoration and repair.


Another advantage of a night’s sleep after eating is the reduction of stress levels. When we’re stressed, our body releases hormones that may hinder digestion and cause inflammation in the gastrointestinal tract. The ability to sleep after eating can lower stress levels and create a more relaxed state, which could help improve digestion and overall well-being.


Additionally, sleeping in the evening after eating may result in better quality sleep. While we go to sleep, our bodies go through various stages of sleep, which include REM as well as non-REM.

These stages are vital to repair and restore our cells. They can also aid in improving mental function, mood, and overall well-being. When we sleep after eating, we aid in promoting these restorative phases of sleep, which results in greater quality sleep for all.


Research suggests that sleeping in between meals can help in weight loss. Sleeping in can reduce hormones that cause appetite and aid in reducing the amount of food eaten late into the night and eating binge.

Furthermore, promoting higher-quality sleep will help us lower stress levels, enhance our overall health, and promote healthy weight management.


Is falling asleep following a meal an indication of diabetes?

Although sleeping immediately after eating can offer advantages, people who are at risk of developing Type 2 Diabetes must know the risk of this behavior. Research has proven that sleeping right after eating can raise glucose levels in the blood, which can increase the likelihood of developing diabetes.

After eating, your body produces insulin, which regulates the blood sugar level. But when we go to bed, our bodies are less responsive to insulin, which could result in higher glucose levels in the blood. This is especially true when eating a big meal prior to bedtime before falling asleep.


A steady rise in blood sugar levels could result in insulin resistance, which is a condition where the body’s response decreases to insulin. This may eventually cause Type 2 diabetes, a chronic condition that is marked by elevated blood sugar levels, as well as a variety of health issues.

How do you sleep after eating safely?

There are many ways to get a good night’s sleep after a safe meal. “We must eat our food roughly couple of  hours before sleep time, as how we finish our dinners is important… Additionally, it is important not to eat enormous meals prior to Bedtime, which is a time when you can experience insomnia and distress. In addition, meal composition is vital to eat an adequate meal that is rich in fiber, protein, and healthy fats. Additionally, engaging in gentle exercises following meals, such as walking, will improve digestion and lower the risk of developing type 2 diabetes.

CGM’s role CGM in enhancing our sleeping habits

Frequently Asked Questions

Why does high blood sugar make you feel tired?

High blood sugar causes your body to produce more insulin than needed, which can lead to a quick drop in blood sugar levels. This “sugar crash” can make you feel tired and lethargic. The inflammation and stress high blood sugar puts on your body can also contribute to fatigue.

Is it okay to sleep after eating?

Sleeping after eating can aid digestion by allowing your body to focus on repair and restoration while you rest. However, eating large meals or lying down too soon after eating can disrupt digestion. Allow 1-2 hours between eating and sleeping for best results.

What are the risks of sleeping after eating for diabetics?

For those at risk of developing diabetes, sleeping soon after eating can raise blood sugar levels during sleep when the body is less responsive to insulin. This chronic high blood sugar can increase insulin resistance and risk of type 2 diabetes over time.

How can you sleep safely after meals?

To sleep safely after eating, have your meal 2+ hours before bedtime and avoid large portions. Eat a balanced meal high in fiber, protein and healthy fats. Take a short walk after eating to aid digestion. Manage stress levels before bed.

How can a CGM help manage blood sugar and sleep?

A continuous glucose monitor (CGM) provides 24/7 data on your blood sugar fluctuations. This helps identify highs and lows, especially overnight, so you can better manage your blood sugar for healthy sleep habits. Popular options are the Dexcom G7 and Freestyle Libre 3.
