Energy

Always tired and a lack of energy?

Many adult prematures have less energy, despite taking sufficient rest. This makes it often difficult for this group to meet all the expectations of the environment and someone has to make choices.

How does it work?

You can see the body as a battery. In the ideal situation our battery starts at 100%. During the day, someone starts doing things such as housekeeping, working or sports. These tasks cost energy and cause the battery to die. Certain tasks cost more energy than other tasks and also cause the battery to die faster. In the ideal situation you will be tired at the end of the day, but still have enough reserves. This reserve is important, because if there is an unexpected situation or a task, it can still be maintained.

In case of a prolonged overload or in case of many adult prematures, this battery often starts at a lower position. In some cases, it can even feel like 50% or lower. In this case too, someone will have to do certain tasks one day. If that is the case, someone will have to claim their reserves more quickly. This person will also be tired at the end of the day, but has no more reserves for the unexpected tasks or situations. If this situation occurs for a long time and someone keeps asking about it, there is not enough rest to build up any kind of reserve. This causes someone to survive and the body is purely concerned with survival and the body is under stress. This position is not helping and will not provide rest and reserves.

But how come?

There is no clear one-sided answer on what causes adult prematures. There are several things that can contribute to a lack of energy. In addition, causes may also lie in life at the moment. For example, illness, stress, poor sleep, hormone abnormalities etc. can also be causes of a lack of energy that are not necessarily related to premature birth. Therefore, stay alert to what is happening at the moment and get help on time from e.g. the GP.

The nervous system:

The nervous system may be part of the cause. In adult prematures, the nervous system is developed differently and reacts more quickly to stress. If someone experiences prolonged stress, the body is in a survival state. This position takes a lot of energy, so the body is purely concerned with survival. Long-term standing in this position causes the battery to run out slowly and not to supplement, because rest is very difficult to experience.

The rest metabolism also called Resting Energy Expenditure (REE):

The Resting Energy Expenditure (REE) has many names and is better known in the Netherlands as the rest metabolism (dust exchange at rest) or the energy consumption at rest.1

In short, how hard the body has to work to stay alive.

The rest metabolism pertains to the amount of energy a person uses to stay alive when someone is in mental and physical rest. In healthy adults, the body consumes about 1kcal/kg of body weight per hour in this state of rest. There is also a difference per part of the body. Thus, the liver, intestines, brain, kidneys and heart constitute about 10% of the total body weight, but require about 75% of the rest metabolism. The muscles require about 20% of the rest metabolism, but represent 40% of the body weight. Finally, fatty tissue requires less than 5% of rest metabolism, but usually represents more than 20% of body weight.2

Several studies have conducted studies on the influence of diet on rest metabolism in adult life in the first few weeks. Here are prematures with a low birth weight compared to those born on time.

It appears that the diet had the most influence on the subsequent effects in the first three weeks. When baby So the body had to work less hard to stay alive. When the diet was looked at at weeks 4 to 9 this had less influence. Part of the outcome was achieved by early growth, but the overall effect was mainly due to the direct effect of early nutrition.3

Another study comparing premature infants shows that higher fat and protein intake resulted in higher total rest metabolism and lower rest metabolism per complete body weight. In short, malnutrition in early life increases metabolism at a later age and consequently requires more energy to survive.4

Research has also been carried out on adult prematures with a low birth weight indicating that their rest metabolism per body weight is higher than in time-born. Socio-economic status, lifestyle, fat percentage, smoking had no influence on this. It is possible that prematures on the metabolic (dust) surface have more active tissue. This may ultimately have a positive effect on the prevention of overweight and hence various chronic diseases associated with it.5

In summary, the metabolism at rest in adult prematures depends on the diet in the first three weeks. This is higher compared to time-borns. In the base the adult premature consumes more energy. All other tasks will be added to this.

Sleep: breathing asleep

Sleep can also affect the energy level. Bad sleep can have several causes. It can be caused by stress, screen usage, irregular working, sleep apnea (breath stops). According to research, adult prematures have a greater risk of snoring, breathing problems due to lung damage and other sleep-distorting breathing problems. This may cause more fatigue during the day.6

Early birth disorders:

Other conditions such aslung damage due to premature birth, brain damage, heart problems and various other diseases arising from early birth increase energy consumption. The body must already make more effort to accomplish the simple tasks, which of course takes more energy than usual.

What can you do?

There are many different ways to work on the energy level. This can be done together, for example, with a psychosomatic therapist or a sleeping therapist. In any case, it is important to exclude physical causes and always consult the general practitioner in case of doubt. In addition, it may be good to talk to the environment about the energy level and to take these people into what is and is not possible. Also for the adult premature itself it is good to learn to recognize their own boundaries, although this can often be difficult.

Practically, resting on a regular basis (no telephone or television) can already help, especially in combination with an exercise such as autogenic training. This is a relaxation exercise in which your body gets orders like it can feel warm and heavy. For this exercise it is only important to listen and the body automatically knows what to do. Other exercises can also be helpful. Certain exercises such as autogenic training can help to charge the battery. By doing the exercise regularly and taking regular rest you can build up reserves in the battery. This will give you more energy and leave you at the end of the day.

How can I make my early birth discussable with my doctor?

In many cases, the GP is the first contact point for physical or mental complaints. He or she listens to the story, asks questions, conducts research and can refer where necessary. So there is a good chance that you will start with the GP at the moment you run into long-term consequences.

It can be difficult to discuss it, because long-term consequences overlap with all kinds of other physical and mental complaints. This can cause a lot of noise and uncertainty. You as a patient experience the complaint and want to do something about it. On the other hand, in a short time (often 10 minutes) the GP must make an assessment of what is going on and what is the best route. As it were, the general practitioner must filter out a lot of information from a patient and determine why this fits in with a particular condition in order to arrive at a diagnosis. If there is a complaint involving a lot of overlap with other diseases, this is very difficult, but not impossible.

Some general practitioners also lack knowledge of the long-term consequences of premature birth and the patient is told that this cannot be the case. General practitioners indicate that they pay particular attention to the period immediately after birth. In their opinion, if a child has developed normally, it is not much different from other children. In prematures, they only see a slightly higher risk of lung problems or development problems (both physically and mentally).* There is therefore often insufficient information on the long-term effects of the general practitioner. Partly because it is generally unknown to general practitioners what changes, for example, around puberty or later on in prematures.

This can cause frustration on both sides in the office. The patient doesn't feel heard or taken seriously. The GP has a patient who is not satisfied and does not receive the right care. This can make a simple problem unnecessarily complex.

Anyway, how do you make this negotiable?

It might already help to get your medical records at the hospital where you were born. This file should be kept for a minimum of 20 years by law. In some cases, it may be chosen to store it for shorter or longer. Making an effort is always worth it. Because you always have the right to request your medical records.

When you are at the GP You can start the conversation by saying that you were born too early and that you suspect you have complaints. Also mention that you have heard about the long-term consequences of peers or have read about them. Always refer to the source where you read it. In addition, you can often ask your doctor for extra time. This way the GP has more time for you and you can also tell your story in peace.

General practitioners may have an interest in the following information:

  • How many weeks were you born;
  • What your birth weight was;
  • Complications in pregnancy;
  • Whether you are part of a multiple;
  • How long you've been in the hospital;
  • A short summary of, for example, 2/3 phrases of what happened at the time in the hospital (e.g. surgery/diseases);
  • What complaints do you now notice as a result.

You can also refer your GP in the conversation to theinformationon thiswebsiteso he can read in. The information is compiled on the basis of scientific articles and the expertise of specialists such as doctors, psychologists, physiotherapists, etc.

But what if all this doesn't work and you're stuck? Then maybe a second opinion at another GP can help you.

The GP

Early birth is a chronic condition

Early birth is a chronic condition. Research has shown that an early birth has consequences even in adulthood.

Thus adult prematures experience more often:

  • Cardiovascular diseases
  • Lung problems
  • Neurological problems
  • Mental problems
  • Metabolism problems
Cardiovascular diseases

Prematures have a higher risk of developing cardiovascular disease early. However, there was no apparent increase in having a stroke or coronary heart disease such as heart attack.

Lung disorders

Pulmonary physiciansfrom Erasmus MC, however, see that many prematures have had lung problems unnoticed throughout their lifetime. They have established the CPL poli where people can go if they have a (suspected) lung disease due to their early birth likebronchopulmonary dysplasia. The doctors indicate that in many cases they can treat this condition well with medication. On the pageBronchopulmonary Dysplasiafind more information about the condition and the CPL poli.

Neurological problems

Prematures can experience various neurological problems. For example, they may have more problems with plans, calculations, executive functions (planing and steering activities), running short-term memory, working memory

In a large part of the cases a person has suffered brain damage or injury as a baby, but thanks to the plasticity of the brain they have been able to develop normally. In these cases no differences were found in the functioning of prematures and on time.

Mental problems

In the area of personality prematures are more often cautious, feel less negative emotions, are more often shy and dutiful. They also show less criminal or risky behaviour and less smoking, drinking or using drugs.

However, prematures experience more difficulty in engaging and maintaining friendships and relationships, possibly because of their withdrawn character. They also experience more anxiety and depression during the transition from child to adulthood.

Metabolism

In the area of metabolism, researchers see that premature type 2 diabetes is more common at young age. Early birth can also have a detrimental effect on kidney development. It can disrupt the further growth of a kidney.

What's the cause?

It is quite possible that the above cases can be explained by several things. First, we look at the pregnancy itself. Here are the genes that someone gets from their parents and grandparents an important influence. In addition, any mental problems or physical disorders of the mother have a major influence on a baby during pregnancy. Even lifestyle and the socio-economic status of the parents are important to the baby.

When a baby is born prematurely, all growth and development processes are disrupted. This must happen suddenly in a stressful irritating environment. It still matters how many weeks a person is born. For example, the brain with 34-35 weeks is not mature enough and the majority of growth still occurs in the last 5-6 weeks of pregnancy. So also the moderately early-born can suffer from this. This while the lungs at 34-35 weeks are already relatively mature and baby disregarded. However, the alveoli still have to develop, so it remains a risk factor for later lung diseases.

Conclusion

These problems therefore arise at a very young age and in many cases persist until adulthood. This is why it is very important to focus attention on this issue. It has to be taken seriously. Many prematures can function relatively normally, some even without complaints. However, there is also a large group that does experience complaints and finds out later. This while they've been carrying a certain complaint their whole life. It is necessary to consider premature birth as a chronic condition.

Also because of the greater risk at later age of developing various diseases due to an early birth which occur only at later age.

It is also recommended for caregivers in the broadest sense to take with them the birth story, pregnancy duration and birth weight of a person by default.

Early birth is a chronic condition

Born premature and then what?

You were born premature, so what? Often prematures receive follow-up from the hospital where they were born. Today it lasts until the 8th year of life. Then the aftercare falls away. Just during puberty and adolescence, much changes in the body and mentally. Many adult prematures say they miss a follow-up at a later age, because they then encounter their complaints or only start developing complaints during that period.

Many adults who were born premature experienced complaints in different areas. Thus they can experience various mental and physical complaints. You can read more on this pageLong-term effects. Nevertheless, adults associate their early birth with words such as fighter, strength, perseverance. Family often describes it as a happiness or a miracle that their baby has been able to develop with the necessary challenges due to its prematureity. Unfortunately, society still describes it too often as fragile, difficult and as a restriction.*

Partly because of this there is often little understanding for this group and they do not get the attention and care they deserve. We want to break through this stigma and see with the prematures what they need in their lives.
