How is this different from normal fatigue?
Ordinary fatigue is a normal and useful reaction: it appears after exercise, is proportionate to it and goes away after rest and sleep. In chronic fatigue syndrome, all three conditions are violated. Fatigue occurs from disproportionately small efforts, lasts disproportionately long and is not restored by rest, no matter how long it may be.
- Significant decrease in the ability to perform usual activities, lasting at least 6 months
- Fatigue is new, distinct, not associated with continued excessive loads
- Rest and sleep do not bring recovery
- Sleep is not refreshing: a person wakes up as tired as he went to bed
- Post-exertion deterioration is a mandatory sign
- Additionally - memory and concentration problems or intolerance to vertical position
- Often accompanied by pain in muscles and joints, headache, sore throat, sensitivity of the lymph nodes
Separately, it is worth mentioning cognitive impairment, which patients themselves describe as “fog in the head.” This is not forgetfulness or absent-mindedness in the everyday sense: it is difficult for a person to keep the thread of a conversation, find words, count, or work with several tasks at the same time. Often it is these complaints, and not fatigue, that become the reason for losing a job, because the load on attention in modern work is high, and from the outside everything looks quite healthy.
Post-exertional malaise is a major symptom
If you have to name one symptom that distinguishes this condition from all other causes of fatigue, this is it. After physical, mental or even emotional stress, the condition worsens sharply, and with a delay: often not on the same day, but after 12–48 hours. It is the delay that confuses both the person and the doctors, because the connection with the load is not obvious at first glance.
- Deterioration does not occur immediately, but after a few hours or the next day
- It is disproportionate to the load: it can be triggered by a simple trip to the grocery store or a long telephone conversation.
- Recovery takes days, sometimes weeks, not hours
- The whole set of symptoms increases, not just fatigue: pain returns, brain fog, sleep disturbances
- It can be provoked by mental stress, stress, and even sensory overload - noise, light, crowd
- A person gradually learns to predict the threshold beyond which deterioration will begin.
There is only one practical conclusion from this and a very important one: you need to plan activity based not on how a person feels now, but on what will happen tomorrow. This is where the basic approach to management comes from - a distribution of forces in which the load is deliberately kept below the threshold, even if on a particular day you feel good. This is counter-intuitive and takes some getting used to, but it does reduce the frequency of severe rollbacks.
What to exclude before making a diagnosis
This is the most practically valuable part of the topic. Chronic fatigue syndrome is a diagnosis of exclusion, and behind the same picture there are conditions that are perfectly treatable. To make a diagnosis without checking them is to condemn a person to years of living with a problem that could be eliminated in a few weeks. Basic examination is inexpensive and accessible.
- Анемия и дефицит железа: общий анализ крови и обязательно ферритин, потому что при скрытом дефиците гемоглобин ещё может быть нормальным, а усталость уже выражена.
- Нарушения щитовидной железы: ТТГ. Гипотиреоз даёт слабость, зябкость, сухость кожи, запор, прибавку веса и снижение настроения — картину, почти неотличимую от описываемой.
- Апноэ сна: громкий храп с остановками дыхания, утренняя головная боль, дневная сонливость. Крайне частая и крайне недооценённая причина, особенно у мужчин с избыточным весом.
- Депрессия и тревожные расстройства: они и вызывают утомляемость, и сопутствуют ей. Отличие в том, что при депрессии обычно снижено само желание что-либо делать, а здесь желание сохранено, но силы заканчиваются.
- Дефицит витамина D и витамина B12, а также нехватка белка и калорий при строгих диетах.
- Сахарный диабет, diseases печени и почек, хронические инфекции, включая гепатиты и туберкулёз.
- Побочное действие лекарств: некоторые препараты от давления, антигистаминные средства, снотворные и успокоительные могут вызывать стойкую сонливость и слабость.
- Целиакия, воспалительные заболевания кишечника и другие состояния с нарушением всасывания.
The distinction with depression deserves a separate discussion, because this is where people most often make mistakes in both directions. With depression, loss of interest and pleasure and self-blame come to the fore, and physical activity usually improves the condition. With chronic fatigue syndrome, interest in life is preserved - the person wants to, but cannot - but stress worsens the condition. At the same time, one does not exclude the other: a long-term illness with loss of work and misunderstanding of others in itself contributes to depression, and its treatment improves the quality of life, even if the underlying condition remains.
Why the advice to “play sports” can be harmful
The advice to increase physical activity incrementally sounds logical and actually works for most conditions with fatigue. But this is where it can make things worse, and this is one of the few exceptions in medicine to the general rule that “movement is good for you.” The reason is post-exertional malaise: a load exceeding an individual threshold does not cause a training effect, but a rollback.
- Programs with a mandatory gradual increase in load, regardless of health, performed poorly in this group and were abandoned
- Instead of “increase” - the principle is “keep below the threshold” and increase activity only with sustainable improvement
- It’s better to split up the activity: several short episodes instead of one long one.
- Between tasks, plan breaks in advance, and not when you’ve already run out of energy
- On a good day, it's helpful to consciously do less than you want - this reduces the likelihood of relapse
- If you are intolerant of a vertical position, many exercises are best performed lying down or sitting
- Complete immobility is also harmful: the goal is not a refusal to move, but movement within the limits of the available
Separately, it is worth mentioning the intolerance of a vertical position, which occurs in a significant proportion of people with this syndrome: when standing up, the pulse quickens, the vision becomes dark, and weakness and fog in the head increase. Quite simple measures help here - sufficient fluid and salt intake in the absence of contraindications, compression hosiery, slow rise, refusal to stand for long periods of time. Sometimes it is recognizing this feature that provides the most noticeable improvement.
What helps: management plan
There is no cure for this condition today, and any promise of a quick recovery should be cause for concern. But this does not mean that there is nothing to help: thoughtful management can significantly improve the quality of life, reduce the number of difficult periods and return some of the usual activities. Work is going on in several directions simultaneously.
- Распределение сил как основа: вести дневник активности и самочувствия, определить свой порог и планировать дела с запасом.
- Восстановление режима сна: постоянное время подъёма, отказ от дневного сна дольше короткого отдыха, ограничение экрана вечером. При подозрении на апноэ — обследование сна.
- Treatment всего сопутствующего, что найдено: дефицит железа, нехватка витамина D, гипотиреоз, депрессия, мигрень, синдром раздражённого кишечника.
- Работа с непереносимостью вертикального положения: жидкость, соль по согласованию с врачом, компрессионный трикотаж.
- Обезболивание и лечение сопутствующих болевых синдромов по назначению врача.
- Психологическая поддержка — не как лечение «выдуманной болезни», а как помощь в адаптации, работе с потерями и планировании жизни в новых условиях.
- Регулярное наблюдение у терапевта: состояние волнообразное, и тактику приходится корректировать.
It’s worth setting realistic expectations up front. The course is usually undulating: periods of relative well-being are followed by deterioration, often without an obvious reason. Full recovery is possible, more often in young people and with early management, but for many it is a matter of significant improvement and life within a framework that is gradually expanding. This kind of honest goal setting works better than waiting for a complete return to the previous pace, followed by disappointment.
Life with this condition: loved ones, work, exacerbations
Much of the severity here is not due to the symptoms themselves, but to the misunderstanding of others. The person looks healthy, the tests are mostly normal, and loved ones sincerely don’t understand why they can’t just get together. This creates a feeling of guilt and makes you overestimate your strength, which directly worsens the course. Therefore, talking with family is not a secondary task, but a therapeutic task.
- Explain to loved ones the deferment mechanism: today’s activity is paid for tomorrow
- Agree on specific assistance in specific matters, rather than “support” in general terms
- At work, where possible, discuss a flexible schedule, breaks, and some tasks remotely
- Do not quit or break ties during the first difficult period: the state is undulating
- Make a plan in advance in case of an exacerbation: what is canceled, who picks up the cases, what minimum is preserved
- Limit sensory overload on difficult days: noise, bright lights, long conversations, phone feeds
- Maintain the minimum available level of social contacts - isolation worsens both mood and flow
Planning rare important events - a wedding, a trip, an exam - deserves special attention. The experience of people with this condition boils down to a simple strategy: decompress the days leading up to the event, minimize involvement in preparation as much as possible, and allocate days in advance for recovery after. This approach does not eliminate rollback, but makes it predictable and manageable, and most importantly, it allows you not to exclude everything important from life for the sake of stability.
