The Other Causes of Constipation

If you’ve ever been constipated, you’ll know how uncomfortable (and embarrassing) it can be. 

Like most people, you’ve probably googled how to treat your symptoms. But the most important part of treating constipation is understanding the cause.  

Most often, being unable to “do number twos” is related to your diet and lifestyle. First, let’s look at some of the most common causes of constipation. 

Lack of fibre

Fibre plays a big part in bowel regularity. Also known as ‘roughage’, fibre is a type of plant matter that can’t be broken down by your body. 

There are two types of fibre: soluble and insoluble. Soluble fibre acts like a sponge, absorbing fluid and making your stools softer. This allows your body to move waste out of your digestive tract more easily. Insoluble fibre adds bulk to your stool, which stimulates peristalsis (the wave-like movements of your intestines). 

Lack of fluids

Dehydration is a major factor in constipation. Your large intestine requires a lot of water to move waste along, and if you aren’t drinking enough, it will soak that water up from food waste instead. The less water in your gut, the drier your stools will be – and the harder to move. 

Lack of exercise

Insufficient physical activity and a sedentary lifestyle can slow down bowel movements. Exercise promotes the flow of blood to the intestines, which stimulates smooth muscle contraction. This is why sitting down all day in an office or long periods of travel can also affect your regularity.

So, what if you’re eating a healthy diet with plenty of fibre, drinking enough water, and exercising daily – but still getting constipated?

It could be that you’re suffering from one of the lesser-known causes of constipation: the ones that are more difficult to diagnose. 

The Other Causes of Constipation 


An underactive thyroid (hypothyroidism) means that your body isn’t producing enough thyroid hormone. This can slow down many of your body’s systems, including digestive function and elimination pathways. If your colon function is too slow or weak, it won’t be able to eliminate stools properly. 

Lead toxicity

Ingesting, inhaling, or touching lead can lead to lead toxicity, an environmental cause of constipation. This is more common in children who may be exposed to lead through paints or by ingesting contaminated food or water. Fortunately, the use of lead-free gasoline has dramatically reduced lead poisoning in recent years, but other environmental sources include fishing weights, vinyl miniblinds, curtain weights, and electric cables. 

As well as constipation, symptoms of lead toxicity include severe abdominal pain, vomiting, and diarrhoea.

Small intestine bacterial overgrowth (SIBO)

SIBO occurs when certain types of ‘bad’ bacteria grow out of control in the small intestine. They ferment and produce hydrogen, causing bloating and gas. This gas, in turn, can slow down stool transit time, leading to constipation. Research has also shown that the higher the methane gas elevation, the more severe constipation becomes.

Worse still, chronic constipation allows more bacteria to grow in the small intestine, which then causes more methane and more constipation. 

Gluten or dairy intolerance

Gluten and dairy products are key contributors to bowel issues. Coeliac disease and gluten intolerance are often associated with diarrhoea, but both can also cause constipation. One study showed that 13% of people with coeliac disease had constipation while 15% had both constipation and diarrhoea. Another 27% had ‘standard’ diarrhoea.

Wheat allergy, celiac disease, and gluten sensitivity are three separate conditions that can all be triggered by eating gliadin, the protein in wheat. Gluten causes an inflammatory reaction in the small intestine which can damage the gut lining, impairing your body’s ability to absorb nutrients. Along with constipation, these conditions can also cause abdominal pain, bloating, nausea, and diarrhoea. 

Dairy intolerance is usually caused by an inability to digest lactose, the sugar in milk. When lactose is fermented by bacteria in your intestines, it can produce methane gas. This methane gas slows down the time it takes food to travel through the gut, leading to constipation.

Other foods that are implicated in constipation include processed grains, red meat, fried foods, and fruits such as persimmons or plums.

How to Treat Constipation Naturally

Most short-term incidents of constipation can be traced back to a certain food or a change to your routine, such as travel. However, chronic constipation suggests that something else may be to blame. 

Because chronic constipation can have so many different causes, there is no ‘one size fits all’ approach to treatment. That’s why a comprehensive consultation with a naturopath like me is so important. I’ll investigate your entire health history, along with your current diet and lifestyle. Where necessary, I’ll recommend that you undergo testing to rule out possible health conditions that may be contributing to your constipation.

Why avoiding gluten is a must for autoimmune thyroid

Avoiding gluten has become something of a ‘trend’ in recent years.

If you have an autoimmune thyroid condition, avoiding gluten isn’t just about being trendy: it’s crucial to your wellbeing. 

Your thyroid is an essential part of your endocrine system, involved in producing many important hormones that allow your body to function. 

About 50-90 percent of thyroid disorders are caused by an autoimmune disease called Hashimoto’s thyroiditis.

Hashimoto’s is a condition in which your immune system attacks your thyroid, often leading to hypothyroidism (underproduction of thyroid hormone).

Symptoms of autoimmune thyroid include:

  • Exhaustion, fatigue, sluggishness
  • High sensitivity to cold
  • Constipation
  • Unexplained weight gain
  • Muscle aches, tenderness, stiffness
  • Joint pain and stiffness
  • Muscle weakness
  • Prolonged or excessive menstrual bleeding
  • Depression
  • Memory lapses

The link between gluten, genetics, and autoimmune disease

Research has shown that some people have a predisposition to autoimmune disease, and gluten is one of the key triggers. This is all to do with the way gluten is digested by the body. 

When we eat, our body recognizes that food is on its way to the stomach and starts making the enzymes needed to digest it. 

If the immune cells in the gut recognise that gluten is in the food, they react by triggering the transcription of DNA required to produce the enzymes for gluten digestion.

However, gluten contains a protein called gliadin, which has a molecular structure very similar to that of the thyroid gland. If gliadin passes through the gut lining (as in the case of Leaky Gut), it enters the bloodstream. The body’s immune cells recognize gliadin as an ‘invader’ and set out to destroy it. 

However, instead of just attacking gliadin, the antibodies will also tell your body to attack thyroid tissue. This is basically a case of mistaken identity

It also means that if you are predisposed to autoimmune conditions, your body is more likely to make the mistake of activating macrophages (your inflammatory immune cells) every time you eat gluten.

In a nutshell, gluten causes your immune system to attack your thyroid.

Having a genetic predisposition to an autoimmune condition is like a switch turned to the ‘on’ position. Your body is simply primed for certain conditions, such as Hashimoto’s thyroiditis. Even though some people can eat gluten without any problems, someone with an ‘on’ switch for Hashimoto’s cannot eat gluten without causing a cascade of inflammation. 

Unfortunately, even a small amount of gluten is off-limits.

Your immune system ‘remembers’ the response to gliadin for up to six months each time you eat it. So, if you have an autoimmune thyroid condition, it’s crucial to avoid gluten completely.

Identifying gluten intolerance

Doctors will usually suggest a lab test to check for gluten intolerance.

However, these tests will only detect antibodies to gluten if they are present in the bloodstream, and this will only happen if gluten has passed through the gut lining.

In many people, this doesn’t occur until the gut lining has become extremely damaged.

Obviously, it would be better to diagnose gluten intolerance before you reach this stage! 

It’s also important to note that Hashimoto’s is primarily a Th1 dominant condition, which means your Th2 system is suppressed. The Th2 system is the part of the immune system responsible for producing antibodies. 

A suppressed Th2 system impairs your body’s ability to produce antibodies, which means they won’t show up on a test. A test for gluten antibodies may not correctly identify Th1-dominant Hashimoto’s.

Stool analysis detects antibodies in waste, which can provide a much earlier diagnosis. A cheek swab test is even more effective as it can detect the genes associated with gluten intolerance and celiac disease. 

Specific genes called HLA-DQ genes are now known to be necessary factors for the development of Celiac Disease (CD). People with these genes are much more likely to have an autoimmune disease, celiac disease and gluten intolerance than the rest of the population. 

Managing autoimmune thyroid

The symptoms of an autoimmune thyroid disorder are very broad in nature, which makes the disorder difficult to treat. Those who do receive a diagnosis are often uncertain about how to manage their condition. 

Autoimmune conditions cannot be reversed or cured. However, with proper diet and lifestyle interventions, symptoms can be managed. That’s where I come in. 

First things first: you must cut out every trace of gluten.

This is essential for preventing your thyroid from being destroyed. There’s also a lot of evidence to show that gluten-containing foods can prevent your body from absorbing nutrients properly and cause all sorts of inflammation in the gut, whether you have an autoimmune condition or not. 

Avoiding gluten isn’t as difficult or as scary as it sounds! I can help you create a nutritious, gluten-free diet to suit your specific needs. We will also discuss how to manage your condition with the right supplements and lifestyle changes.

What Is The Autoimmune Protocol? An Overview Of AIP

The Autoimmune Protocol (or Autoimmune Paleo Diet) is commonly recommended for people with chronic, inflammatory and autoimmune disease.

But what is this protocol, and who is it suitable for? Let’s take a closer look at AIP, its benefits and drawbacks.

What is AIP?

The AIP diet is a protocol that involves eliminating and then reintroducing a number of potentially problematic foods.

The major purpose of AIP is to identify foods that may be causing issues and reduce inflammation in the gut. However, other benefits such as fat loss, improved energy, relief of brain fog and reduction of pain may also highly likely.

When you follow AIP, you will eliminate grains, dairy and processed foods. Some healthy options such as nuts, seeds, beans, legumes and nightshades are also removed as they can be inflammatory for some people.

Instead, you’ll focus on wholefoods such as fruits, vegetables, organic meat, eggs and wild-caught fish. You can continue to use healthy oils and fats and flavour your meals with herbs.

Who is likely to benefit from using AIP?

Although AIP is primarily designed for addressing autoimmune conditions, it could potentially benefit any health concern that has inflammation. Examples of conditions that may improve using an autoimmune protocol include:

  • Hashimoto’s disease
  • Coeliac disease
  • Rheumatoid arthritis
  • Multiple sclerosis
  • Sjogren’s
  • Type 1 diabetes
  • Lupus
  • Ankylosing spondylitis
  • Graves disease
  • Psoriasis

Everyone is unique, so just because you have an autoimmune condition doesn’t mean you have to follow AIP. But if you find that your autoimmune symptoms and flares are causing issues, it is worth considering.

Remember that AIP is not a long-term diet

The right amount of time to follow AIP can vary from person to person. Some will only need the elimination phase of the diet for 30 days, whereas others may up to 3 months.

It is a therapeutic diet used to reduce inflammation and reset the body. It is not a ‘diet’ that you should be following long-term as it restricts many foods that offer health benefits.

That’s why it’s important to proceed with the reintroduction phase and continue to eat as much variety as possible without triggering your symptoms.

My tips for following AIP

As a practitioner who has personal experience with AIP, I know that it’s not the easiest protocol to follow! But there are some ways that you can make it easier on yourself.

Focus on the foods you can eat, not what you eliminate. Get creative with meats, fish, fruit and veggies. You can still make plenty of delicious meals using the ingredients included on AIP. Think of it as an opportunity to reset your taste buds and your gut.

Choose what works for you. People ask me whether they should go into AIP cold turkey, or go step by step with eliminating foods. It depends on the situation – where you’re at physically and mentally and what your overall knowledge and experience with wholefoods is like.

Eliminating foods overnight can be a massive stress, which is a problem when you’re working on a condition where stress is a trigger. So if you prefer to take it slow, go for it.

Reintroduce slowly. Start with one food group that doesn’t contain any other groups – for example, don’t reintroduce dairy using ice cream, as it contains sugar and potentially additives.

Work with an experienced AIP practitioner. Any elimination diet should be done under the supervision of a qualified nutritionist who has worked with AIP clients. They can guide you through what to eat, what to look for in terms of symptoms, and how to proceed with reintroduction.
