Constipation is a really common problem in children and babies. This is especially the case for bottle-fed babies, as well as those who have stopped breastfeeding. Exclusively breast-fed babies rarely get constipated. So, can you give lactulose or Microlax to treat constipation in babies and children?

Read further to learn more about constipation in babies and children, how to treat it, and the use of lactulose and Microlax. Facts and advice by pediatricians.

Symptoms of constipation

The symptoms of constipation vary, and not all children have all the symptoms. Those who have constipation have difficulty defecating or think the stools are hard. Many have stomach aches which are sometimes associated with mealtime. Some have pain in the bum, perhaps because the hard stool has caused a tear. And if the constipation is really bad, some feel sick and vomit. Loss of appetite and whining is also common, in children with constipation

Constipated diarrhea

Fecal traces on underwear, or stool leakage (aka fecal incontinence) is usually the result of constipation. Sometimes there is such a large mass of feces stuck in the colon that the pressure forces some feces to seep through, leading to smeared underwear. This also makes it difficult to detect constipation, because everything that comes out is so loose.

Anal Fissure – tear in the rectum

Anal fissure is a tear in the rectum opening caused by passing a hard stool. As a result, there is often quite a lot of pain and fresh blood in the toilet. It’s not dangerous, even though it may look otherwise. However, the child undoubtedly needs constipation treatment. Pain-relieving ointment to the rectum opening before toilet visits can also help. Seek a medical center when convenient.

When an anal fissure heals, a small mucosal flap may form in the rectum opening. This doesn’t bother the child at all.

The vicious cycle of constipation

When the stool becomes hard and difficult to pass, children will avoid going to the toilet. The stool remains in the intestine and subsequently, the colon mucosa absorbs more fluid from the stool. This makes the stool even harder and even more difficult to pass. Once the child tries to poop, it hurts even more. So the child will hold on even longer. A vicious cycle of constipation continues.

In a child who is not constipated, the rectum is empty. When it is filled with fecal matter, signals are sent to the brain; it is time to poop. In a constipated child, there are feces in the rectum most of the time. The gut sends signals to the brain, and when it is not possible to poop, the signals are interpreted as pain instead. Or, the gut gets tired of sending signals that don’t lead anywhere, and consequently, the child stops feeling the urge to poop.

Treatment for constipation

The aim of long-term treatment for constipation is to break the vicious cycle and to allow the signalling system between the gut and brain to be recovered. This process takes time, generally several months. Therefore, it is important to continue treating constipation until the child has developed confidence and a rhythm in pooping. Do not stop after a week or two even if the child poops every day.

In mild constipation, dietary changes may be sufficient. Obviously, the child needs to embrace these dietary changes. Picky eaters, however, may need to skip this step and be given medication right away.

Foods that help relieve constipation

Prunes or pear purée

The most classic household remedy for constipation is, prunes. It works quite well against milder constipation. Of course, it’s easier said than done. Giving prunes to a discerning preschooler is like giving cooked stomach to an adult. But for babies who eat canned food, you can try giving prunes or pear purée.

Whole grains and high-fiber food

High-fiber food is usually recommended for constipation. There are 2 types of fiber: soluble and insoluble fiber. Soluble fibers absorb water from the surroundings and becomes sticky and gel-like. This is great at improving digestion, but because it absorbs water from its surrounds, it can be difficult to pass. Therefore soluble fibers, such as whole grain products, can help, however, ensure the child drinks plenty of fluids. On the other hand, insoluble fibers are great for children. Fiber-rich, moist fruits such as well-ripened pears, plums and apples, tend to aid the passing of stools.

Dairy-free

Many people try a dairy-free diet to help relieve constipation as the child may have a form of cow’s milk protein allergy. In isolated cases, it works. However, in the vast majority of cases, it doesn’t help. And if that’s the case, it’s important the child starts drinking milk again.

Toilet routines to treat and prevent constipation

For children who have stopped wearing diapers, it is good practice to introduce a toilet routine. Allow the child to sit 10 minutes on the potty /toilet twice every day. Preferably after meals when the intestine has an easier time emptying itself. Some toddlers just want to poop in their diapers for a long time. Then let them do so, if that’s possible. Let them sit on the potty with their diaper on. The squatting position and floor support can help with their bowel movements.

Medications for constipation

If dietary changes and toilet routines do not help, medications are needed to treat the constipation. It is extremely common for children to take medications for constipation at some point during childhood. And some may need it for many years.

Lactulose

Lactulose is a liquid medicine for constipation. It consists of long sugar molecules that are not absorbed into the blood stream but instead, settle in the intestine. There, the lactulose molecules extract water from the intestinal wall to loosen the stools. Lactulose tastes sweet and therefore tends to be easy to give to most children.

Lactulose is available without a prescription at a pharmacy. A common dosage to start with is 5 ml twice daily, reducing or increasing the dose according to results. The Bristol stool scale, a stool classification chart, is a great aid in deciding whether you need to increase or decrease the dose. Preschoolers usually find it quite fun.

A common but harmless side effect of lactulose is gas, which can cause stomach aches. Lactulose is harmless and can be used for many years without the intestine becoming “dependent” or damaged. Due to the gas, Lactulose is not usually favored in schoolchildren and teenagers. If your child needs constipation treatment longer than three months, seek medical advice to rule out underlying cause.

Movicol, Omnilax, Forlax etc (Macrogol)

Macrogol has many different brand names. They are sold as powder in sachets that dissolve in water. Some brands have the junior sachets that contain half the amount as an adult sachet. Of course, you could just as well buy the adult sachets and use half as much.

Macrogol is a type of fiber that settles in the intestine and attracts fluid to soften the stools. It is effective and generally doesn’t cause gas as a side effect. The disadvantage is that it can be difficult to get children to take the solution.

The different varieties taste a little different. Movicol has a salty taste that many people do not like, and that cannot be hidden by juice or similar liquids. Omnilax or Forlax do not have the salty taste and are usually better tolerated.

An adult sachet or 2x junior sachets is usually a good starting dose for school-age children. At pre-school age, a junior sachet or half an adult sachet is a good starting dose. Increase or decrease the dose according to the Bristol stool scale as advised. These medicines are slow acting and you do not have to be prepared to go to the toilet immediately after drinking them. Defecation becomes easier the next day.

Lactulose is harmless and can be used for many years without the intestine becoming “dependent” or damaged. If your child needs constipation treatment longer than three months, seek medical advice to rule out underlying cause.

Enema

If the child has severe constipation and acute stomach ache, an enema may be helpful. An enema is inserted into the rectum and will hopefully lead to rapid bowel movement, within about 5-20mins.

Klyx

Klyx is an efficient and fast-acting enema available without a prescription in pharmacies. For fever-free children over 1 years old, with a stomach ache, and otherwise good general health, where you suspect constipation, you can try inserting a 120 ml Klyx enema at home. It is often rapid and effective. But it’s common for the symptoms to reoccur in the near future. Therefore, lifestyle and dietary changes are often needed, and in some cases, children require daily medication for a period of time.

Microlax

Microlax is a small microenema that works by irritating the intestinal mucosa and thus encouraging the stools to come out. This is often effective, but it stings and hurts many children, so choose Klyx instead.

Resulax

Resulax is also a small microenema, but unlike Microlax, it does not sting. It is a good alternative to Klyx. Many find it easier to insert Resulax into the rectum as it is smaller and smoother.

Common causes of constipation in children

Constipation commonly arises due to a change in the child’s life (eg. diet, environment etc) and not commonly because of any underlying disease. During childhood, three periods of constipation are most commonly seen.

  1. Transitioning from breast milk to formula, or from breast milk/formula to solid food.
  2. When the child stops using diapers.
  3. When the child starts school. Many children do not want to poop in school. Often because the toilets are untidy, toilet paper is missing, the doors cannot be locked properly, or that other children will bang on the door or otherwise disturb them. There’s a lot to fix here!

Other changes may include travel, stressed periods and common infections. The latter affects the intestine in several ways. On the one hand, the infection itself can change the intestinal flora, as is the case for gastroenteritis. On the other hand, children usually eat and drink worse when they are sick. This combination, together with fluid loss due to vomiting, diarrhea, fever or increased breathing, results in drier and harder intestinal content.

When should I seek medical care for my child’s constipation?

Severe, acute problems, or palpable abdominal pain that does not improve after Klyx, needs to be examined by a doctor the same day.
