My Experience of Pituitary Tumour and Pregnancy

I’ve already written about my experience of hypermobility and pregnancy (and birth!), so it feels like time to write about my experience with my pituitary tumour (pituitary adenoma).

My Experience of Pituitary Tumour And Pregnancy

Before trying for a baby

My husband and I went to talk to my endocrinologists about the possibility of trying for a baby over a year before we actually wanted to start trying (we had a wedding in between!). And it was just as well we did, because there was a lot of planning involved…

At the time, I was taking a medication called Somatuline Autogel (lanreotide) for my pituitary adenoma. There’s no data on its safeness (or otherwise) in pregnancy, and in fact it isn’t even technically licensed for my condition. I have a pituitary tumour which produces thyroid stimulating hormone (TSHoma), and they’re so rare that there actually isn’t any medication licensed for the condition. However, I’ve taken lanreotide on-and-off for nearly ten years, and fortunately it always worked well to control my symptoms.

But because it’s not known how safe lanreotide is in pregnancy, my doctors were keen to see whether I could manage without the medication during a pregnancy – or whether my thyroid levels would start going up again. So I agreed to do a trial period off the medication. All went well for a couple of months, and then I could feel my symptoms coming back, and blood tests confirmed that my thyroid levels had risen again. So, a new plan was needed.

My doctors then suggested trying cabergoline, a drug that’s used for a different kind of pituitary adenoma called a prolactinoma. They estimated to me that, based on their previous experience, there was about a one in five chance of it working for my tumour as well. And although cabergoline is not licensed for use in pregnancy, there have been more case studies etc. of women using it in pregnancy, so my endocrinologists thought it would be a better bet than lanreotide… If it worked for me.

So I have it a go… And it worked! To my surprise, it was just as good as lanreotide, if not better because it’s much more convenient. With cabergoline, I take two tablets per week (weird schedule, I know), whereas with the Somatuline Autogel it was an injection once a month which my husband had to do, and we had to keep the injections refrigerated beforehand. Plus, with Somatuline, because it messes with the function of your gallbladder, I had to eat an extremely low fat diet for 5 days out of each month, which could be a real pain when we were out and about. So not having to do that was a real bonus!

During Pregnancy

During the course of my pregnancy, I had to have blood tests once a month to check on my thyroid levels. Fortunately, they were well controlled throughout the whole time. I also had some bonus hospital visits so my endocrinologists could check up on other symptoms. Because the pituitary naturally enlarges during pregnancy, they like to check up on your visual fields to ensure that between that and the tumour, it’s not putting pressure on your optic nerve.

Planning for Breastfeeding

I really wanted to try breastfeeding, but being on cabergoline meant that could be tricky. Cabergoline inhibits the production of prolactin – the hormone that stimulates the production of breastmilk. My doctors recommended that I stop taking cabergoline six weeks before my due date, to give myself the best chance of breastfeeding, as the drug takes about four weeks to leave your system. Hopefully I would then be able to breastfeed for a couple of months before my symptoms returned and I had to go back on the medication.

So, I duly stopped taking cabergoline at 34 weeks… And then Little Man showed up at 37 weeks, rather earlier than expected! Breastfeeding didn’t work out for us. Although I made colostrum, my milk never came in, and it’s not clear whether it’s because the cabergoline wasn’t out of my system yet, or the stress and separation when Little Man ended up in intensive care for several days.

Planning for the Birth with a Pituitary Tumour

With regards to the birth, my endocrinologists were confident I could have a normal birth. Because the pituitary is involved in producing the hormones that kickstart childbirth, I did ask whether there was any reason to think that I might be less likely to go into labour naturally. But the doctors said that there was no evidence that women with pituitary tumours are more likely to need inductions.

The doctors did specifically write in my notes that I was allowed to have an epidural, as they said sometimes people can mistakenly think it’s not allowed after having transsphenoidal pituitary surgery. They also advised that there should be steroids on hand, to be administered if I experienced any unexplained low blood pressure, in which case an adrenal crisis should be suspected. Fortunately it wasn’t needed.

What advice do I have for other women with a pituitary tumour who are trying for children?

After two transsphenoidal pituitary surgeries, there was always a risk that the function of my pituitary gland had been damaged by the surgery and I might find it difficult to conceive. Fortunately we were very lucky and I was able to get pregnant. Because we knew it might take a while, we planned a long time ahead, and I’d definitely recommend talking to your endocrine team to work out a plan of action well in advance of when you want to start trying to conceive.

Trying me on/ off various treatments took over a year from when we first discussed it, due to delays from the hospital’s administration and us deciding to go back on my regular medication for the three month period of our wedding and honeymoon, to make sure I felt well for it. If we had been actively wanting to start trying for a baby, that would have felt incredibly frustrating and slow. It was frustrating enough even when we knew we didn’t want to start trying until after the wedding!

My Experience of Joint Hypermobility Spectrum Disorder and Pregnancy

I thought it might be useful to write a post about my experience of Hypermobility Spectrum Disorder (formerly known as Joint Hypermobility Syndrome, apparently rheumatologists like renaming stuff) during pregnancy, as I would have found it helpful to read something like this when I was pregnant!

What is hypermobility spectrum disorder?

Basically it’s an overarching term for a group of conditions relating to joint hypermobility – i.e. in simplest terms, your joints extend more than they’re supposed to. I was diagnosed with it when I was 17, although at that point they called it joint hypermobility syndrome.

I actually meet the diagnostic criteria for a condition called hypermobile Ehlers-Danlos Syndrome (hEDS) although I’ve never been formally diagnosed with it. I did once see a dermatologist about something totally unrelated, and as it turns out he specialised in the dermatology of hEDS and was very excited to run a bunch of tests on my skin.

Hypermobility Spectrum Disorder and Pregnancy

How can hypermobility affect pregnancy and birth?

I was referred to an obstetrician once I was pregnant, thanks to all my stupid medical conditions, and she discussed the key potential issues from my hypermobility spectrum disorder and pregnancy, which basically are:

  • Risk of the birth progressing quite quickly once you reach 4cm dilated.
  • Risk of poor or slow wound healing.
  • Risk of resistance to local anaesthetic.
  • Risk of waters breaking early.
  • Risk of additional pain during pregnancy due to the extra weight and hormone changes placing stress on the joints.

So which of these issues did I actually encounter? I’ll go over them in order…

Increased joint pain during pregnancy

Oh boy did I get this one. It actually started very early too, around week 12 or 13 – well before any significant weight gain, so I assume the issue was caused by the hormone relaxin, which your body produces during pregnancy and causes joints to loosen. If you already have loose, hypermobile joints, that’s not great.

You’re recommended to sleep on your side during pregnancy, but I found that when I slept on one side, the hip on the bottom would gradually partially dislocate during the night and it would eventually wake me up with the pain. Then I’d swap sides, and it would repeat on the other side. By the end of the night I would only be getting maybe half an hour on each side before the pain woke me up, and my joints were so sore and stiff in the mornings. It was not fun, and it got worse as my baby bump got bigger.

I did, however, find that physiotherapy really helped. I saw a great NHS physio who have me exercises to strengthen the muscles around my hips and it made a massive difference to my pain levels, although it didn’t cure it completely.

I’m now four months out from the birth and I would say that although the sleeping pain resolved basically as soon as I have birth, I can feel that the pregnancy has had a lasting effect on my left hip joint, which feels noticeably less stable and more often painful than previously.

Premature rupture of membranes

My waters broke at 36 weeks and 5 days, which is technically premature, but only just (37 weeks is technically full term). Premature rupture of membranes (waters breaking early, if you’re not a doctor) is a risk of hypermobility, so it’s possible that it was related.

Hypermobility and rapid labour

I didn’t go into labor naturally but was induced due to my waters breaking. I was put on the syntocinon drip and told to expect to progress by dilating about half a centimetre per hour. The midwife said she would check on my dilation at about the four hour mark, and that she expected me to progress about half a centimetre dilation per hour.

Two hours later I was in massive amounts of pain, they weren’t letting me have gas and air (because they said you had to be 4cm dilated first) and I felt that I definitely couldn’t cope with another 12 hours or more of it, so I asked for an epidural. The midwife put in the request, but the anaesthetists were in theatre so it wasn’t going to happen any time soon. Shortly afterwards, I got the very distinct feeling that my body was starting to push. I told the midwife but she didn’t seem that bothered. Fortunately, my husband then insisted that she check how dilated I was. She had a look, realised I was fully dilated and that I was indeed pushing.

Then it was panic stations! The midwife apparently had to write loads of stuff on the computer at this point, and thus had to call in a second midwife to take over with me.

Although the dilation stage had happened really quickly, the pushing stage did not. Fortunately they did let me have gas and air at last, which helped a lot with the pain.

They wanted the baby out within two hours of starting pushing (not sure if this is standard or due to the fact my waters had broken a long time before and they were worried about infection). At some point, a doctor appeared and said that if I didn’t make good progress in the next two pushes, they were going to do an emergency caesarian. Seemingly I did make enough progress, because she went away again. Then, some time later, a couple of other doctors appeared and said I had two pushes before they would do a ventouse (suction cup) delivery.

Resistance to anaesthetic

In order to get the baby out, they had to do an episiotsomy, which then needed stitches. They gave me local anaesthetic before the stitches, but it really didn’t work, I kept telling the doctor doing the stitching that I could feel it. So I guess I did have the resistance to local anaesthetic issue.

They didn’t seem to be clued up on my hypermobility and the plan to manage it during the birth, because they also used the normal dissolvable thread for the stitches, instead of the silk sutures I was supposed to have, to assist in case of poor wound healing. The dissolvable stitches were okay for me in the end fortunately. One stitch broke, but that could have been because I did so much walking to and from the neonatal intensive care unit in the week after Little Man was born (he developed a very serious case of jaundice and had to go into NICU). I didn’t notice any issues with healing, thankfully.

To be fair, the mess up with the stitches and the insufficient local anaesthetic may have been due to the fact that after Little Man arrived, I had a big post-partum haemorrhage. The alarms went off and lots of doctors and nurses suddenly appeared in the room, luckily I didn’t need a blood transfusion but was put on a drip and super woozy. So it was all a bit crazy in the delivery room, and I can see how things were missed. But I did think it was disappointing that, despite having flagged a lot of these potential issues well before the birth, we were still left with them not being managed very well – especially the rapid labour. Looking back I am annoyed that I was in so much pain with no pain relief and they didn’t even think to check my dilation to see whether things had progressed further than they were expecting.

What advice do I have for other hypermobile mamas-to-be?

If you’re pregnant and have hypermobility or hEDS, I recommend flagging it early to the hospital, but being prepared to advocate for yourself in the delivery room. It’s hard to do when you’re actually in labour yourself, so make sure your birth partner knows about your hypermobility and how it can affect pregancy and birth, and that they’re confident to advocate for you. I dread to think how long I would have been pushing before they thought to check my dilation, if it hadn’t been for my husband advocating for me.

I also highly recommend physiotherapy, as early in the pregnancy as possible. A lot of hospitals have long waiting lists for physio, so try to get on the list as early as possible.

My Pituitary Gland Has A Great Sense Of Timing

So, I have a super rare tumor on my pituitary gland. It’s called a TSHoma or thyrotropinoma, because it produces thyroid-stimulating hormone (TSH). I’ve had surgery on it twice but we’ve never quite been able to get rid of it, there’s still a teeny stumpy bit left.

There’s actually technically no approved medical treatment for my condition, because it’s so rare, but for many years I was treated off-label with a medication called Somatuline, which is used for another kind of pituitary tumor and worked well for mine. However, when my husband and I decided we wanted to try for a baby, my endocrinologists suggested trying another medication, also off-label, usually used for yet another kind of pituitary tumor. It’s called cabergoline and they suggested trying it because it’s been used slightly more often in pregnancy compared to the other medication I was on. My doctors thought there was maybe a one in five or one in six chance that it would work to treat my tumor, so I was pretty pleased when it did.

Cabergoline stops you lactating, because it inhibits the production of prolactin by the pituitary. As I wanted to have a chance at breastfeeding, we agreed that I would stop taking the medication six weeks before my due date with Little Man, to give it a good chance to leave my system and allow me to produce breast milk before he arrived.

As it turned out, Little Man had his own plans. My waters went at 36 weeks and 5 days, and he arrived at 37 weeks exactly (just 2 and a half hours away from being technically premature!). Breastfeeding didn’t work out for us, but when I saw my endocrinologist a few weeks after the birth, I wasn’t having any symptoms from being off the medication, so we agreed I would stay off it for now. I was due to return in three months, and get in touch if my symptoms came back.

Well, now that coronavirus is here and I really don’t want to go to the hospital or GPs, my symptoms are back and I want to go back on my medication. It’s not terrible so far, just occasionally a fast heart rate, feeling a bit jittery, and the odd shooting pain in my neck (always the most unambiguous sign that my thyroid is doing something weird).

The hospital has introduced a great new telephone system where you can’t just phone a department directly, you have to go through a central switchboard. This is great because it means that you can wait on hold for ages to explain why you’re calling to the switchboard operator, who then explains that they can’t help you and will need to put you through to the department. Then you’re on hold again, which is brilliant because the hold music is not at all deeply irritating. Then either a) no one answers and the call just terminates, or b) someone answers and you get to explain why you’re calling again, so they can tell you that they’re not the right person to talk to and they’ll put you through to the relevant person. Then the relevant person isn’t in, so you’re told they’ll call you back. Then, when they don’t call you back, you get to start the whole process again.

It really is a genius of modern system design, because previously when I had to call the hospital, I sometimes only reached medium levels of furious hatred at their appalling administration, whereas now I reach maximum capacity every time.

So, last week I sent an email to my endocrinologist’s secretary, in a bid to avoid having to telephone hundreds of times until my soul is macerated completely and starts to run out of my nose. However, I have not heard back and my symptoms are only getting more noticeable, so I guess telephoning is now my only option. I can’t wait!

The pituitary gland is also known as the hypophysis. And that’s not just a hypothesis.
