Why Am I Always Constipated?

Chronic constipation isn’t just about fibre or water. If you’re constipated most days, straining, or never feel fully empty, your gut is signalling deeper issues, such as motility, hormones, stress, or microbial imbalance. This article explains why constipation persists, what it really means, and when diet changes alone are not enough.

Always constipated and nothing seems to work? Discover the real, often ignored causes of chronic constipation, from poor gut motility to fibre mistakes and what actually fixes it, backed by science.

16% of adults worldwide experience chronic constipation

33% of adults over 60 are affected regularly

2×more common in women than men

Chronic constipation affects hundreds of millions of people globally, yet most of us are too embarrassed to talk about it. The result? We suffer in silence, reaching for laxatives that only mask the problem. Let's fix that, starting with understanding why it keeps happening.

What does chronic constipation actually mean?

Chronic constipation means having difficult, infrequent, or incomplete bowel movements for at least 3 months. This includes passing stools fewer than three times a week, excessive straining, hard stools, or feeling like your bowels never fully empty. Frequency alone doesn’t define constipation effort and stool quality matter more.

In Indian adults, daily bowel movements are common, so a sudden or long-term change should not be ignored. Constipation is one of the most common IBS symptoms. What is IBS and why is it misdiagnosed in women?

Why am I constipated even after eating fibre?

If fibre isn’t helping, the issue is usually hydration, fibre type, gut motility, or microbiome imbalance. Adding fibre without enough water can harden stools, while certain fibres worsen symptoms in sensitive guts. Constipation that persists despite “healthy eating” often points to a functional gut problem, not a fibre deficiency.

🚫 You’re not drinking enough water (and you probably know it)

Your colon absorbs water to form stool. When you’re dehydrated, it pulls extra water from waste, leaving stools dry and hard. Studies show increasing fluid intake improves stool frequency and consistency.

Quick check: if your urine is dark or tea-coloured, you’re dehydrated. Aim for 2–3 litres daily, more in hot Indian climates or with physical activity.

Low fibre intake: the most common contributor

Most adults consume only 10–15 g of fibre daily, far below the recommended 25–38 g. Soluble fibre (oats, apples, flaxseed) softens stools, while insoluble fibre (vegetables, whole grains) adds bulk and speeds transit. Both are necessary, but only when paired with hydration and movement.

Can stress and hormones cause constipation?

Yes. Stress and hormonal changes directly slow gut movement through the gut–brain axis. Chronic stress activates the fight-or-flight response, reducing blood flow and nerve signalling to the digestive tract. Hormonal shifts further relax intestinal muscles, delaying stool movement.

If constipation worsens during exams, deadlines, PMS, or emotional stress, the cause is neurological and hormonal, not dietary.

Chronic stress is literally stopping you up

Stress slows colonic transit time, allowing stools to harden. This explains why constipation often flares during prolonged mental or emotional strain, even with an unchanged diet.

Your gut and brain are in constant conversation through the gut-brain axis, a two-way communication network connecting your central nervous system to your enteric nervous system (the "second brain" in your gut). When you're stressed, your body activates the fight-or-flight response, diverting blood flow away from digestion.

A landmark study in the Gut journal found that psychological stress slows colonic transit time, meaning food moves more slowly through your large intestine, giving it more time to harden. If your constipation gets worse during exams, work deadlines, or emotional upsets, stress is likely a major player.

Hormones play a bigger role than most people realise

Constipation is twice as common in women. Progesterone slows intestinal movement, making constipation common during the luteal phase, pregnancy, and perimenopause.

Thyroid disorders also matter significantly. Hypothyroidism (underactive thyroid) is a well-documented cause of chronic constipation. The thyroid regulates metabolism, and a slow metabolism means slow everything, including digestion. A 2019 study in the Thyroid journal found constipation was present in up to 48% of hypothyroid patients.

Do gut bacteria affect bowel movements?

Yes. The gut microbiome plays a direct role in stool bulk, softness, and frequency. People with chronic constipation have fewer beneficial bacteria and reduced production of short-chain fatty acids, compounds that stimulate colon movement.

Antibiotics, restrictive diets, infections, and chronic stress can all disrupt microbial balance and slow peristalsis.

🦠 Your Gut Microbiome Might Be Out of Balance

Beneficial bacteria help regulate stool movement. When depleted, gut contractions weaken, leading to slow transit, bloating, and hard stools, even with adequate fibre intake.

Your gut houses trillions of bacteria, fungi, and other microorganisms, collectively called the gut microbiome. Research from Nature Reviews Gastroenterology & Hepatology shows that people with chronic constipation have measurably different microbiome compositions, with fewer beneficial bacteria like Bifidobacterium and Lactobacillus and higher levels of harmful strains.

These bacteria produce short-chain fatty acids (SCFAs) that directly stimulate colon movement. When beneficial bacteria are depleted, from antibiotics, poor diet, or stress, peristalsis (the wave-like muscular movement that pushes stool forward) can slow significantly.

SIBO is another reason for chronic constipation that doesn't get better.

Food intolerances and digestive slowdown

Undiagnosed lactose intolerance, gluten sensitivity, or FODMAP sensitivity can contribute to constipation (and sometimes alternating constipation and diarrhoea, a hallmark of IBS). If you notice your constipation is worse after dairy, bread, or certain fruits, an elimination diet or food sensitivity test may reveal.

Is constipation a sign of an underlying condition?

Persistent constipation can signal thyroid disorders, IBS-C, pelvic floor dysfunction, medication side effects, or metabolic conditions. Treating symptoms without identifying the root cause delays recovery and increases complications like fissures and haemorrhoids.

Constipation with pain, bloating, or alternating diarrhoea should never be self-managed long term.

💊 Medications that secretly cause constipation

Many commonly used medications slow bowel movements:

• Opioid painkillers (codeine, tramadol)

• Iron supplements

• Calcium- or aluminium-based antacids

• Certain antidepressants

• Antihistamines

• Blood pressure medications (calcium channel blockers)

Always discuss symptoms with your doctor; never stop medication on your own.

🚽 Ignoring the urge to go

Repeatedly suppressing bowel urges trains the rectum to become less sensitive, a condition called rectal hyposensitivity. Over time, stools accumulate, harden, and become harder to pass.

Pelvic floor dysfunction is often missed

In many women, especially post-childbirth, pelvic floor muscles fail to relax during defecation.

Sedentary lifestyle and slow gut motility

Physical activity physically stimulates the muscles of your intestines. Studies show people who exercise regularly have significantly better bowel function than sedentary individuals. Even a 20-minute walk after meals can measurably speed up intestinal transit time. If you sit at a desk all day and don't move much, your gut is likely slow too.

💊 Medications That Secretly Cause Constipation

This is one of the most overlooked chronic constipation causes. A wide range of common medications slow bowel movements as a side effect:

• Opioid painkillers (codeine, tramadol): slow gut contractions dramatically

• Iron supplements: a common culprit, especially in pregnancy

• Antacids containing aluminium or calcium

• Antidepressants (tricyclics especially)

• Antihistamines (allergy medications)

• Blood pressure medications (calcium channel blockers)

  
  

If you've recently started a new medication and notice constipation, speak to your doctor. Do not stop medication without medical guidance.

Pelvic floor dysfunction is often missed in women

For some people, particularly women who've had children, the pelvic floor muscles don't relax properly during defecation. Instead, they tighten, physically blocking stool from exiting. This condition, called dyssynergic defecation or anismus, is estimated to affect 25–50% of people with chronic constipation. It doesn't respond well to fibre or laxatives; it requires pelvic floor physiotherapy.

🍫 Ultra-Processed Foods and the Gut-Wrecking Diet

Ultra-processed foods (biscuits, packaged snacks, instant noodles, fast food) are typically stripped of fibre, loaded with refined starches, and high in sodium. They slow gastric emptying, feed harmful gut bacteria, and provide nothing to bulk up stool.

A large cohort study in The Lancet found that high consumption of ultra-processed foods was independently associated with increased constipation risk.

The rule of thumb: If the food has unnecessary additives such as emulsifiers, certain artificial sweeteners and colourants, it may harm your gut health.

When to See a Doctor About Chronic Constipation

Occasional constipation is normal. But if you're experiencing fewer than 3 bowel movements per week for more than 3 months, or if constipation is accompanied by:

• Blood in stool or on toilet paper

• Unexplained weight loss

• Severe abdominal pain

• Alternating diarrhoea and constipation

• Feeling like bowel movements are incomplete

  
  

...please see a gastroenterologist. These could be signs of IBS, IBD, colorectal cancer, or other conditions needing medical attention.

FAQ

Is it normal to be constipated everyday?

No. Daily constipation is not normal and usually indicates slow gut motility, hormonal imbalance, or pelvic floor dysfunction.

Can drinking more water alone cure constipation?

Only if dehydration is the cause. Many people with chronic constipation are well hydrated but have motility or microbial issues.

Are laxatives safe for long-term use?

Regular laxative use can worsen dependency and weaken natural bowel reflexes. They should not be a long-term solution.

Can iron or calcium supplements cause constipation?

Yes. Both commonly harden stools and slow bowel movements, especially without gut support.

Is constipation linked to thyroid problems?

Yes. Hypothyroidism is a well-documented cause of chronic constipation and should be ruled out if symptoms persist.
