ME/CFS in pregnancy, birth and postpartum.

As any sufferer of ME/CFS will know, getting answers to questions relating to your wellbeing is notoriously difficult. Having questions answered during pregnancy is no different. According to the world around you -  health professionals, bosses, clients - you are the same as you were before, except now you’re pregnant. 


Despite the advocacy efforts of incredible patient groups and enlightened research professionals, the evidence around what happens to the pregnant and birthing body in ME is sparse. We know that ME sufferers get pregnant and give birth - I am case in point - but the diversity of experiences, much like the illness itself, makes it difficult to pin down things that might help.


Being pregnant in and of itself is a strain on the body. You’ve got to grow brains, bones, sinew and vital organs. Some research suggests over the course of pregnancy a person will need to consume 50,000 calories (Samuel et al 2024). This equates to the energy needed to run 30 marathons. Now I’ve never run a marathon but I have been pregnant with ME twice so I guess I’m an athlete now? But seriously, the toll this can take on an already depleted system is significant and one that we don’t talk about enough. 


Since becoming a doula I’ve been thinking more and more about how unbelievable it is that people with chronic conditions manage it all. The physical, spiritual and mental impact that having a child has on people is hard to overstate. So being pregnant with a battery pack that’s half juiced is a pretty big undertaking. And that’s before we’ve even got to thinking about birth. 

With all of this, knowing what I know, but also knowing that my case is on the milder end of the wildly diverse spectrum, how can I be the best support to people in a similar boat? If you’re pregnant or planning to be, postpartum or have a loved one who is facing this incredibly magical but incredibly draining season of life, I humbly offer here a few things I think might help. But first, let’s take a look at what the research says… 

The Research

ME/CFS affects an estimated 250,000 people in the UK, the majority of whom are women of reproductive age. Despite its prevalence the evidence base around pregnancy, birth and the postpartum period for people with ME/CFS remains remarkably thin. The most comprehensive review to date - a mixed-methods systematic review by Slack et al. - essentially concluded that the current evidence around ME/CFS in pregnancy is limited, inconclusive and that more high-quality research is urgently needed. 


What data does exist paints a genuinely mixed and highly individual picture. One retrospective survey found that 41% of respondents reported no change in symptoms during pregnancy, 30% improved, and 39% got worse (Schacterle & Komaroff, 2004 ). Some specialist clinicians report higher rates of improvement particularly in the second trimester, thought to be related to the immunological and hormonal shifts of mid-pregnancy (Allen, 2008), but these are not particularly robust studies.


What is absent from almost all of this is clinical guidance. The ME Association, which is currently funding a pilot study specifically examining pregnancy in ME/CFS, has acknowledged the lack of evidence in the area and the need to establish clear clinical guidelines. This means a person with ME/CFS planning a pregnancy in the UK is navigating a maternity system with no tailored clinical guidance, no obligation on care providers to adapt their approach, and no pathway to specialist support specific to their condition.

ME/CFS in pregnancy

Being pregnant with ME is at once amazing (look at my body doing what I have asked it to do!) and also confusing (is this normal pregnancy tired or ME tired?). This miracle that your body is suddenly performing following years of giving you absolute grief is confounding to say the least. 


For many people with ME there are hallmark symptoms, or rather the ones you become overly familiar with. These are different for everyone. For me they have been consistently fatigue (shocker), brain fog, a buzzy body (a feeling you’re nervous system on the fritz), floaty body (dissociation), lightheadedness and dizziness and a whiplash of debilitating flu like symptoms following any audacious uptick in mental or physical load. 


It sounds quite the cocktail and it is. But I'm also used to it. One of the most annoying parts though is when your body sends you a weird curveball every once in a while. I once  felt like my organs were on fire for a week for example and another time my lower limbs felt so heavy I just couldn’t mobilise for an extended period. Every so often my life just seemingly capsizes for a bit, and just as I reach the point of acceptance that this is going to be my new life forever, the boat flips back over into its ‘normal’ ME state. So for what for most would be a panicked dash to A&E, for the ME/CFS aficionado is just another spin round the merry-go-round. 


And that’s when the intersection with pregnancy gets quite spicy. This unfamiliar ground throws up many a new symptom. Morning sickness is perhaps the most expected, you know when it hits and can handle it to some extent. Other things that come out of the blue that are less known however can bring a sense of fear and unease. For example when you feel you might pass out suddenly during your second trimester or have weird heart palpitations in your third, it is hard to know whether ME is playing tricks on you or if it's something you should genuinely investigate. The mind can play horrible tricks when you are in such a high-stakes state and the sense of responsibility for decision-making around yours and your baby’s health can be crippling. 


There is discourse in the birth world to ‘trust your body’ in birth and pregnancy. This can be quite triggering for the chronically ill who have been betrayed by their bodies often for years. That kind of trust once broken is very hard to regain which adds a level of precarity to pregnancy that is hard to describe. So the same body that couldn’t get out of bed for days because you had an extra glass of wine at dinner, worked for that extra hour in the evening, or watched that extra episode of trash tele too late is the same body I’m supposed to grow and birth the most precious thing imaginable? It's hard to imagine, even harder to trust.  


I wish I could write a long list of all the weird and wacky symptoms we can put in the ‘normal’ box to give my fellow CFSers the mental break they so deserve. However, given the lack of high quality research around ME in pregnancy there is little I can offer beyond an expansion on my own experience and what I found to be helpful. This may all be futile given the expanse and diversity of experience (not to mention possible co-morbidities and complications to pregnancy) out there but if one person can take even one little nugget then it’ll be worth it. So here goes, some titbits you might put in your locker:


  • Add a dollop of conservatism to your energy planning - i.e. ditch optimistic pacing. Pregnancy tired + ME tired do stack. So if you’re used to having a restful morning to account for work in the afternoon, stick some extra buffer time on top of it to account for pregnancy (if you can!)

  • Pace even on your good days - don’t let that second trimester trick you into thinking you have extra reserves. It’s so great to feel great but don’t let it bite you in the bum too hard by going wild as a result (tell that to the me that thought I could handle a festival with thunder crotch).

  • Get a good team around you - not everyone ‘gets’ ME and that’s ok. Having trusted people who I could share my fears and concerns with was invaluable. Get over your fear of telling clinical teams about your condition (I know, I know they ignored you before but keep telling them) and someone might just write it in your notes.  

  • Build an ME-aware birth plan - we all know that birth can be a marathon and can be exhausting beyond belief. Help yourself as much as possible by planning for the most rest as humanly possible - think restorative positions, genuine nourishment, conservation in early labour and avoidance of interventions that will prolong and potentially complicate your labour.

  • Don’t accept complete exhaustion as normal. This is a weird one I know as often people with ME have fatigue that isn’t improved with rest. However if you feel completely depleted and cannot catch your breath this could be a sign of some form of iron deficiency, thyroid or other clinical issue which is worth exploring with your GP. I caught some very low iron levels in my second pregnancy which I was able to get supplementation for for example. This can be hard to do, I know. As a community we are used to adding symptoms to our rosters and generally avoid the doctor for fear of dismissal but your pregnancy health matters and if there is something else going on then you may be able to find some support.

  • Get to know your local Maternity Assessment Unit (MAU) -they provide urgent care, monitoring, and triage for pregnancy-related concerns. I am a BIG believer in trusting your gut so if anything is truly niggling at you then it's worth contacting them for peace of mind. 

  • Don’t google your symptoms - this needs no explanation.

ME/CFS in birth

The CDC (the leading public health authority in the US) currently recognises post-exertional malaise (PEM) as the hallmark symptom of ME. PEM is a worsening of illness that can start immediately or hours to days after even minor physical or mental activity and can last for hours up to several months. Given that labour is one of the most physically demanding events a body undergoes, it will require specific preparation for people with energy-limiting conditions. 


I was very lucky in the sense that my baseline was relatively high in my first pregnancy following a year of health and relative work-life balance. This is not to say that birth didn’t scare the shit out of me. I worried a lot. I worried about being in labour for days (I was) and for interventions that would knock my nervous system, spirit and energy into the stratosphere (they did). Turns out all that worrying was not only unhelpful but incredibly draining to my already limited energy. Turns out what I thought would help my energy (early pain relief if needed) turned out to be the thing that obliterated it. 


Second time round I was going to do it differently. I designed a much more energy aware plan that was much more focussed on managing my interactions with the maternity system, cluing up on birth physiology and practising self-advocacy. For the soon-to-be parents out there here is what I’d consider again for an energy aware birth-plan:


  • Find positions that don’t drain energy - lying over the birth ball, or side lying with peanut ball in between the legs were personal winners

  • Rest in early labour - it's very exciting when it all kicks off, but resist the urge to feather the nest and rest rest rest!

  • Minimize interventions that extend exertion - non-clinically motivated induction for example.

  • Consider pain relief wisely - it might help you rest but it also might lead to further complications.

  • Birth where you feel safe - if this is at home in your paddling pool or in hospital hooked up to every machine, feeling safe is going to make your labour experience so much better.

  • Get a support team that knows and understands your condition - if the midwife or care team hasn’t heard of it, educate them. It’ll be worth it for your peace of mind. Tell them at every appointment (when care continuity is absent).

  • Get a doula - research shows doula support during childbirth can increase the chances of vaginal birth, shorter labours, decrease the need for pain medication, improve the perception of the birthing experience, and even lower levels of postpartum depression (Sobczak, Alexandria et al. 2023). A good one will help you build a plan that accounts for your baseline. 

  • Make sure your birth partner knows your plan - having someone who knows you inside out and can advocate for you in the moment will make all the difference.

  • Ditch the shame - it is a slippery slope to shame-town when we don’t feel we’ve birthed in the “right” way. All birth is valid and legitimate and if that means booking a C-Section in avoidance of labour (note recovery is also major!) then so be it. 

ME/CFS in the postnatal period

People with ME/CFS already experience profound fatigue that doesn’t go away with rest. The postpartum experience overlays completely new levels of sleep deprivation and physical recovery on top of this. How does someone with ME manage this? Current clinical guidance for ME in general is to observe a pacing strategy to regulate symptoms. The problem is, this requires a level of control over your output that is wildly incompatible and unrealistic with a newborn. If you are ‘allowed’ 10 minutes of mental exertion an hour, how on earth are you meant to deal with 30 minutes of high-stakes decision-making in the middle of the night when you’re operating on limited sleep?


In the (highly unlikely) event that I were going into this period again, in an effort to mitigate the sledgehammer of postnatal exhaustion, I would design a postnatal plan beyond all postnatal plans. I would have enhanced support beyond what would normally feature. This would include:


  • Be forthcoming in the 6 week GP checkup: I would flag my ME to the doctor and push for this to be integrated into my postpartum care. I fell into issues with both my mental and physical health following pregnancy and I wish this context had been captured. 

  • Proper mental health check-in - some studies, although not particularly robust, have found higher levels of postnatal depression amongst mothers with ME (Underhill 2009). As someone with ME I was very used to dealing with feelings of doom, despair and generalised anxiety which may have masked some symptoms of PPD. I would have a frank conversation with loved ones about how I was feeling, how I was presenting and if this felt different to the normal low-mood of managing a senseless illness.

  • More side-lying boob - having my body physically horizontal for the seemingly billion hours of breastfeeding as a more restful position

  • Limiting visitors - trying to recover whilst hosting is near impossible, even with the loveliest of loved ones. 

  • Doula support - I would get a kick-ass doula who was well-versed in newborns, nourishing meals and even ME (if there is such a person excluding myself). Knowing they were coming once or twice a week in the early postnatal period would be mentally so alleviating. 

  • Accept help - if you’ve got it. Ask for more of it than you think. 



This is all needless to say but not everyone can afford to have so much extra support built in. Our communities are not designed well for the postpartum period and sadly huge inequalities abound. ME/CFS additionally poses a severe economic burden causing high unemployment and significant income loss, disproportionately affecting those with low household incomes. *Please note that if you're on a low income or facing financial hardship, you can access free or heavily subsidized doula support through several UK charities (Doula UK access Fund, Doula without Borders, Birth Companions, Neighborhood Doulas). To qualify, you usually need to be referred by a midwife, social worker, or healthcare professional.*  


Beyond these very practical plans and the usual batch cooking etc. it's worth naming the fear that can also come with the postpartum period with particular regard to relapse and symptoms worsening. This is one of the most reported concerns in the ME/CFS community and deserves honest discussion. Relapse just doesn’t feel possible with the gargantuan responsibility of raising another human. 


As well as this, the emotional weight of grief, guilt, and identity when your body can’t do what you ask of it is a lot to carry and something you might mention to your care team to build context around your mental health. This is especially important for detecting postnatal mood disorders when ME/CFS already affects mood, sleep and cognitive function. 


To round off I would like to say that if any of this resonates with you or you have any questions you’d like to ask about your own experience with ME in the perinatal period then please do not hesitate to reach out. From one parent to another, I see you, this shit is hard, but my goodness your babies are going to have one tough cookie as a parent!
