The Dangers of Feeding THICKENERS To Your Special Needs Child.

Updated: May 12, 2020

Following a prolonged bout of urine infections and projectile vomiting, Carys did not drink fluids, at all, for three years. Speech therapists introduced thickeners as a way to get her drinking again. Faced with a wall of eight superficially smiling speech therapists, three radiographers, a strange high-chair, and a huge x-ray machine, Carys commenced screaming and choked all the way through her barium swallow test. The results were inconclusive, I was told; best start her on thickeners, just to be on the safe side. I had misgivings; I didn’t believe she had any swallowing issues, but they were the experts, and I was intimidated.

I tried various feeding cups until I found one Carys liked. About three months after she started drinking, the periods of screaming started. Each one lasted for about four days, often did not stop at night, and recurred  in a cycle of every ten to fourteen days. I was at my wits end; she seemed in such agony, yet doctors could find nothing wrong with her. Finally, one morning I took her out of her cot, and her nappy was bone dry. She was drinking about a litre of fluid a day, more than she had in years, and yet her nappy was completely dry, something which had never happened during all her years of not drinking anything at all. We went to A&E.

Carys was diagnosed with Chronic Constipation and Impaction. Her bowel had swollen so much, it was pressing against her bladder and preventing the escape of urine. How could this have happened? If anything, I thought she was suffering from diarrhoea; apparently, liquid stool is a sign of constipation, but who knew that? She was started on a high dose of Movicol to liquefy the impaction and keep it all moving. I was warned that it could take up to a year for the bowel to recover and begin to function normally again.

A few days later, the Movicol took effect. The less said about that, the better! But finally, Carys had some relief. I consulted a nutritionist, began counting her daily fibre intake, and that was the end of that… or so I thought.

A week later, Carys was screaming again. And so the cycle continued. Even with all that Movicol (up to ten sachets a day) and her daily requirement of fibre, and regular enemas. I investigated the causes of constipation; lack of fibre – definitely not; not drinking enough – no, it only started after she increased her fluid intake; lack of exercise – difficult one to address in a non-mobile child; lots of medication – yes, but I couldn’t stop those, and anyway, her prescription had not changed in years, so why would it be causing a problem now?

I was convinced that Carys must have some other underlying condition. Her older brother had been born with Hischsprungs Disease; could she have it too? Unlikely, doctors told me. What about her Thyroid? Tests proved it normal. Diabetes? No. Ok, so maybe it’s something else, like a twisted bowel, or a blockage? Xray and ultrasound could find nothing wrong. Finally, a doctor said there was nothing more he could do. That is probably the worst thing he could say to a stressed and weeping mother at the end of her tether, carrying a child who was screaming and writhing in unexplained agony.

There had to be a reason. This was not normal behaviour for Carys. But it seemed only I believed that. A year later, and Carys had missed a lot of school. Her development had not moved forward at all during this time, in fact, she had regressed. She was no longer the happy, loving child she always used to be. It was impossible to take her anywhere, she would scream the whole time. All she wanted to do was rock on her belly on the floor of her bedroom, where she felt most safe and comfortable, I suppose. If anyone out there believes constipation to be only a mild, temporary condition, think again. It's debilitating and all-consuming. Carys’s pain and unhappiness was affecting the whole family. Do you know how it feels to watch your child in agony, and not be able to do anything to help her? And let me just add, I’m no selfless hero; there were times when Carys’s screaming got to me so much, I just wanted to close her bedroom door or leave the house, so I didn’t have to listen.

It was down to me, but what did I know? I was expert in nothing. So I turned to Google and began my research and found that adding more fibre to a weakened, traumatised gut was like feeding more cars into a traffic jam: it was going to get slower and finally come to a stop. It was only going to get worse.

I changed her diet, cut out grains and starches, increased green veg, and reduced the amount of thickeners in Carys's fluids. Basically, she was following a low-carb diet, much like the popular keto diet, although I didn't know that then. I waited to see what would happen.

And gradually, she started to improve.

On July 21st this summer, Carys had her first day completely free from thickeners.


We have decreased her Movicol to three sachets daily. She has not had a single enema since July. And she is having a bowel movement every day. Oh, and she has never choked on her fluids, or inhaled any, either.

Before Carys went back to school, I went to see her doctor and explained my theory, prepared for a battle. “Ok,” he said, looking at the report from the swallow test. "I don’t know why she was put on thickeners anyway; there’s no evidence of aspiration in the report. I’ll write a letter to her school.”

It’s not coincidence. I believe thickeners in large quantities are not safe. If your child is suffering from constipation, but doesn’t take thickeners, look again at her diet.

Corn flour/ maize starch is added to lots of foods that you wouldn’t think needed it. It’s usually GM modified, too. Be wary of ‘hungry baby’ milk formulas, check their ingredients carefully.

Hospitals and care homes use thickeners routinely in everything to avoid the risk of choking. A couple of spoonfuls used to thicken a sauce or gravy won’t do any harm, but more than that might, depending on your child’s sensitivity. I don’t want to scare anyone, but it took me a year and a half of stress and suffering for Carys to find this out for myself. I’m sharing our story, in the hope that it might help someone else.

Happy little Carys!

Of course, there are many conditions which can cause constipation, so do always get your child thoroughly checked out by a doctor.
