Conversations about constipation

Clinical

Like most of you, I have to deal with constipation issues within the ED or CAU environment, and most of the time, it’s not the reason the child attends the department! This can lead to a series of awkward questions and issues that parents may ask that we must consider to provide safe, sound, and, most of all, worthwhile advice! 

So let’s go through these questions and issues:

1. My child has a UTI. Why are you talking to me about constipation? 

This is something I get asked not only when a UTI is diagnosed but also about other clinical conditions, including appendicitis, bedwetting, incontinence, urinary retention, obstruction, etc…. it is important that parents understand the implications of constipation, not only from pain and symptoms point of view but also the complications surrounding it. Indeed, many parents also struggle to understand how their child, who is rolling around in agony, is only suffering from constipation (you can feel them questioning your medical acumen). 

During these tough times, I always mention two key points. Firstly, the fact that your bowel covers the majority of your abdomen. A build-up of wind and solid matter in the bowels can bring about severe, gripping abdominal pain when pressing against sensitive nerves. As it covers a lot of your abdomen, when full, it will compress other structures like your child’s bladder, leading to urinary infections, incontinence and retention. The second point is that stools are like toxins your body wants to expel. When it remains in your bowels, it can get into small structures like your child’s appendix and cause it to become inflamed, which leads to appendicitis.

Also, the longer the stools sit in the colon, the more water is absorbed, leading to harder, solid stools. This will cause a blockage and lead to vomiting and obstruction, which may require surgery. 

Once parents understand these points, they’ll be less likely to roll their eyes at constipation! 

2. How are they constipated if they go every day? 

In fairness, this is a good question that used to throw me quite a bit in my early paediatric years, but let’s break it down. Constipation is not simply the time between going to the toilet; rather, it is the build-up and insufficient clearance of stools in your bowels. With this in mind, a child can go daily and pass small amounts of stool but still have a backlog of faecal matter in their bowels. Therefore, also question the time spent on the toilet, straining and pain during defecation. These are all signs of constipation. If you can, ask your young patients, too! 

3. They already drink plenty of fluids

Don’t let this answer fool you. Explore the parents’ meaning of fluids. When we say it, we mean clear liquids like water and squash (preferably sugar-free), but for the parents, it’s anything from water and tea to milk and hot chocolates.

There is a myth that milk makes us constipated, but that’s not the case… well, not entirely. Milk is indeed a liquid, and it doesn’t make us constipated, but it’s thicker and takes longer to digest (hence why in surgery, they stress only clear liquids 4 hours before). Milk fills up the child, reducing their intake of solid food, which will be full of fibre. 

Always remember, parents may say they’ve cut out all the milk, but this may have been substituted for milky teas and hot chocolates, so double-check! 

In terms of managing the milk, appreciate the difficulty the family is about to face. Wean the milk down slowly, starting with the bottles in the middle of the day, then the morning bottle and finally the night bottle. Milk shouldn’t be stopped entirely. Having a 250- 500ml glass of milk daily is perfectly fine. 

4. They eat a good diet 

Whenever I get this response, I immediately think they haven’t, and 99% of the time, I’m right—that says a lot. 

Again, this is either due to a misconception about a good diet or they don’t think it’s an important issue, so they brush it off with this generic statement to get to the medication that will help. Another quick way to check is to ask the child. They usually find it much more difficult to turn a blind eye.

I always try to tackle this in one of two ways:

Tell me what they eat.

It’s surprising how many children don’t have breakfast or any of the three square meals daily. If they do, add tips when you can.

Breakfast: Dried fruits in cereal (especially raisins). Don’t switch the cereal completely but mix in an All Bran, so they’re still getting their tasty favourites, but now with added fibre. Toast—if it’s white bread, freeze it; it’ll keep longer, and placing it straight into the toaster means that the strands of carbs, fats, and protein are bound together and form fibre.

Lunch: Try to include salad in sandwiches. If the parents say they dislike a salad, how do they expect their children to? Encourage healthy eating in the parents as well, to form positive connotations for their kids.

Dinner: Any sauce can hide a multitude of veggies if blended or chopped fine enough – so get them cooking and, where possible, get them to encourage their kids to join in. If they cook it themselves, they’ll appreciate the food and, for some reason, enjoy it more

probably a labour of love! And it’s a great time to leave out and pick on a bowl of fresh berries or grapes; the more accessible things are, the more they get eaten.

Do they eat all their fruit and vegetables?

This again leads to a classic ‘Yes’ response – which falsely reassures many healthcare professionals. In truth, it’s a vague and rather inadequate question to ask. If I told you that my child eats peeled apples and pears, has a glass of orange juice, and then eats loads of veggies, I boil them until they are soft. It might make you think twice about the goodness they’re getting.  So I always ask – Do they eat the skins of the fruit and vegetables? How do you prepare them?

The skin of most fruits and vegetables contains the majority of fibre and various vitamins and minerals required. In all honesty, if you peel apples and pears, you’re left with sugar and water, so I tell parents to give their children the peel instead! 

Again, I suggest microwaving or steaming with veggies, as people tend to overcook them when they boil them. They need a crunch, as that equals fibre. Root vegetables (potatoes, sweet potatoes, carrots, butternut squash, celeriac, parsnips) – all these lovely fibre-rich foods – contain most of the fibre in their skins. I tell parents to roast them long and slow – they’ll taste better (caramelizes the sugars in the veg/skin), so children will prefer them! 

Be mindful of smoothies and fruit juices. Yes, they can count for one of our five a day (soon to be 10 a day), but they can have little to no fibre, especially with the models that separate the pulp. The pulp is fibre!! Try to get them to have whole fruits instead or one 250ml glass of fruit smoothie daily with the pulp. 

5. I have tried all this, and it doesn’t work 

Before you dismiss this answer, make sure you look over the medical background again (cystic fibrosis, hypothyroid disease, Hirschsprung’s). Ask these all-important questions:

In all of these conditions, the child would have always had an issue with constipation since birth, so don’t miss them. 

Once covered, it’s important to review what they have tried. Most parents will only have been given a packet of Movicol and told to get on with it. Look at the summary section to structure a constructive management plan.

6. I’m scared they’ll starve, so I give them what they want. 

How many of us have been told this with little Jonny sitting there looking larger than life?

In general, throughout the developed world, children are unlikely to starve if their parents try to feed them a healthy, balanced diet. There are caveats to this:-

These children will need extra support and input from community and nutritional teams. 

All the other children will always put up a fight (usually a good one!), but then their bodies will give in and want food. This is an important step for parents to understand, especially when the child is too young to go out and get food themselves.

Make sure you tell the parents this won’t be a simple task, and children typically win because carers will be busy and won’t have time to tackle this problem. It’s a quick fix to give them something so they know they’ve eaten

.then the habit starts. I always tell parents to wait until they have a week off and prepare yourself/ yourselves for a bumpy ride. Have a united front; it’s no good if one parent plays the ‘strict/ bad guy’ while the other feeds the problem behind their back. Prepare meals, hide away the unhealthy processed snacks (or don’t buy them first), and leave the fruit out. Again, get the child involved in cooking, build a healthy connection with food and make it fun. Children will most likely throw tantrums at the start, but remind them that their child’s body will eventually give in, and they will come for food, most likely with grumpy faces. 

Just make sure they’re hydrated with clear fluids—no milky substitutes. Remind the parents they’re not bad people, which will help fix things in the long run.

7. Movicol doesn’t work, and I don’t want it to make their bowels lazy 

This age-old answer makes you wonder why we bother using Movicol. They’ve often not prepared it correctly, despite the instructions being in the box. Honestly, the ways parents use Movicol are endless: sprinkle it on cereal, mix it into snacks or food, add it to tea
.the list goes on!

Movicol is only effective when it is bound with water. After this, the parent can mix it with a small amount of other liquid or flavouring. Make sure they don’t add it to a litre bottle of squash, as the child will have to drink the whole lot. Also, this means they don’t need the flavoured versions (which taste vile – remember when they made you try them in medical school!). 

Another myth is that “it’ll make their bowels lazy.” Explain that Movicol is not a stimulant. It is an osmotic diuretic that drives the water you mix it with into the child’s stool to make it softer and easier to pass. With this in mind, even stimulant laxatives won’t make your bowels lazy. I always say, they can be on it for the rest of their lives, it’ll never make their bowels lazy – that tends to reassure parents.

8. I tried laxatives before, and they suddenly had diarrhoea, so I stopped using them. 

This answer may again lead you to think that the laxative has done a great job in under 72 hours and fixed a month’s worth of constipation. Does it sound too good to be true? Well, it is. The big problem is that if clinicians don’t warn the caregivers about what might happen after starting a laxative, it can lead to long-term mistrust in both the medication and our advice.

I always start by setting the day to start. Aim to start the laxative at the end of the week, a Thursday or Friday, to avoid accidents in the school. They will deter the child from ever trying them again.

Once we know when to take them, we always triple-check that they’re using them correctly: Mix with water first, then add to a small volume of any other liquid for taste.

Finally, but most importantly, the change in stool. Referring to the Bristol stool chart (the only card I carry around!), I explained that the child will start with Type 1-3 stools. Then, they’ll have what looks like diarrhoea, brown, watery, smelly stools, but it’s overflow. Take the time to discuss why this happens; the Movicol is slowly moving through the hard stools, like rain trickling down a wall, in their child’s bowel. The Movicol/water mix will initially run over it, but their stools start to soften over time. 

The next step, again important due to the risk of pain, is the big logs. And big means big! I’ve had parents say they’ve used shears to cut up these stools in the toilet. This is essentially the wall slowly being emptied. 

Once this is over, they will finally have soft, mushy stools. The laxative story should not end there! It is essential to mention that this ‘wall of stool’ has caused the bowels to stretch. This will lead to a build-up of stools again as the child won’t know when they need to go. This is reservoir constipation. It can take months to revert to normal, so I always advise continuing with the laxatives and reducing (but not stopping) the daily maintenance dose if the child is passing clear watery liquid. Usually, treatment should continue for at least three months to treat reservoir constipation (although in some children, it can be longer).

9. They don’t like my cooking. They’re vegetarian now, and I’m not. 

It doesn’t have to be vegetarian, of course. This is just what an angry mum said to me once about her daughter. Parents will mention the difficulties of preparing food they’re not used to cooking. I always suggest ‘get your child involved’. This is the perfect time to do something together (bonus points in tackling mental health and isolation- it gets the family talking). The child will appreciate their intent and willingness to give their lifestyle a try, which will build confidence in the relationship as well. They can get a cookbook, go online (it’s free and easily accessible these days) and adapt their cooking style. Again,this will make their child feel more involved and interested in cooking and eating healthy foods. 

10. They don’t like fruits and vegetables. 

We’ve all suffered from hating vegetables and fruit at some point. I remember hating tomatoes and peppers, so I feel for any parent tackling this problem. 

There are several factors to contend with here:

I usually offer several solutions, but parents will have busy lives around their child’s eating habits, so it has to be a conscious effort at a convenient time, like over the weekend or during annual leave.  

Firstly, hide unhealthy snacks or reduce the amount you buy; what they don’t see, they don’t know
. out of sight, out of mind technique.

Secondly, I always tell carers they and their older siblings are role models. If you’re not eating it, why should they? Parents should present a united front. 

Finally, get cooking and get your child involved. Any child who cooks will appreciate the food they’ve made and the sense of achievement. Even if it doesn’t taste nice, they’ll love it. It’s a great time to chat over a bowl of fresh berries.

My enthusiasm then tends to kick in. I like to say, “Get creative in the kitchen!” I’ve mentioned simple things. For example, make flapjacks and throw in lots of dried fruits: raisins, dates, apricots, prunes – all-natural sweetness with skinned nuts & oats. Freeze smoothies with the pulp into ice lollies. Fruit crumbles with honey and oats
 When cooking vegetables, always remember to steam or microwave them. They need the crunch. Again, if kids don’t like them
. Chop them up/ blend them, throw them into sauces and pies, and mix them into other dishes. If it’s the taste they don’t like, again, mixing it into gravy or a tasty sauce will fix that problem! 

It is important to mention the importance of a healthy, balanced diet. Food is your best medicine. This can be true for managing many conditions: anaemia, skin problems, poor immunity, and nail and hair problems..you get my point. A varied diet holds the key to many management plans, and it’s important to mention this even when the child is on supplements. A classic example is the parent says we’ve fixed the iron problem with iron tablets, but they fail to realise, without vitamin C your body can’t absorb the iron through the small intestine. Therefore, they’ll be questioning why their child remains anaemic in months to come. 

11. They’ve gone back into nappies as they’re scared of using the toilet. 

This is an important issue. It means the child will probably have problems with incontinence, which may affect their social life, such as staying over at a friend’s house. Yet another reason why it needs tackling. 

Always start by asking what happened. More often than not, it’s a series of bad habits and untimely events that have led to a regression in the family’s good practices. It happens to the best of us. Reassure everyone and give them positive reinforcement that they’ve identified a problem that needs to be solved. Then, offer the advice below. Take your time with these parents. It would have taken a lot for them to come into an acute setting to seek advice, so try to give them some. 

A framework for managing constipation.

This is an important topic you will likely encounter at some point in your paediatric career. Knowing how to manage it is a core skill. 

I always frame my management in 3 steps: 

1. Diet and fluid intake—Take the points from the above questions. Ultimately, the parents control the diet and food at home. They and their older siblings are the child’s role models, so what they eat will also influence the child’s diet. Remind them that food is their family’s best medicine, so they need to get it right. Cancel out the milky drinks, cook smart and healthy, and don’t forget clear fluids.

2. Toileting—Our constipation module covers this, but key points are to get them into a routine (20 to 30 minutes after dinner—to sit on the toilet), make the toilet a fun place with all their toys and gadgets, and don’t forget to get them to blow the bubbles. Optimise positioning with knees above bums when sitting, using a footstool. 

3. Medication – ensure parents are giving them correctly – mixing with water first then adding to any other liquid for taste. Ensure this isn’t a full bottle, as they’ll have to drink the lot!. Movicol doesn’t make your bowels lazy. If they’re on a disimpaction regime, think about the volume they’ll drink each time. It may be better to split it into thrice-daily doses instead. Briefly touch on the sequence of stool changes to reduce misconceptions of overflow and diarrhoea. Lastly, start Movicol towards the end of the week, Thursday or Friday, to avoid accidents at school.
