Improving Your Digestive Health - How to Avoid and Treat Constipation

Constipation is one of the most common digestive complaints in the UK, affecting people of all ages. We all know that heavy, uncomfortable feeling that comes when your digestive system slows down. Whether you’re looking for a solution for yourself or you’re trying to ease your child’s discomfort, the priority is finding gentle, reliable relief.

At 121 Pharmacy, we focus on the practical side of gut health. We’ve designed this guide to help you pinpoint why constipation happens and, more importantly, how you can avoid it. From simple lifestyle shifts to selecting the right laxative treatments, we want to make sure you feel your best every day.

What is Constipation?

Forget rigid definitions for a moment and let’s focus instead on your physical comfort. Constipation isn't just the ideal number of bowel movements in a week; it’s the discomfort of passing hard stools, the ache of bloating, and the exhaustion of straining.

If you notice your child avoiding the bathroom or if you personally feel like your system has slowed to a crawl, you are experiencing a common constipation symptom. Don’t worry because you don't fit a specific ‘three-times-a-week’ rule, watch out for when your usual pattern changes and leaves you feeling uneasy, that is what matters most. Identifying these shifts early allows you to address the causes directly and restore your family’s healthy digestion.

What Causes Constipation?

Understanding why your body reacts to certain triggers allows you to fix them. Constipation often develops due to a combination of lifestyle, dietary, and medical factors. Below are the most common triggers.

1. Low Fibre Intake - Without fibre, there is no ‘sweep’ for your digestive tract. Processed foods lack the structure needed to keep waste moving. Adding high-fibre products to your diet is an effective way to prevent sluggishness. Aim to include more fibre-rich foods such as:

  • Wholegrain bread, rice and pasta
  • Oats and bran cereals
  • Lentils, beans and chickpeas
  • Fruit such as pears, apples and berries
  • Vegetables including broccoli, carrots and leafy greens

2. Insufficient Fluid - Water is essential for soft, easy-to-pass stools. When you’re dehydrated, your waste becomes dense and painful. Consistent sipping throughout the day is your best defence.

3. Sedentary Habits - Physical stillness leads to digestive stillness. By incorporating even light exercise, you manually assist your intestines in moving waste along.

4. Suppressed Urges - Your bowel has a ‘window of opportunity.’ Missing it by choice or circumstance causes waste to sit longer, dry out, and become a problem later.

5. Chemical Triggers - Medicines for blood pressure, depression, or pain can chemically slow your system. If your medicine cabinet is the cause, we can look at your options together.

6. Hormonal Influence - Progesterone shifts during pregnancy or your menstrual cycle can significantly relax your bowel muscles, leading to a backup. It’s a natural reaction, but one that requires active management.

7. Medical Alerts - Sometimes, your gut is signalling a deeper issue like a thyroid disorder or IBS. If you notice severe symptoms, blood, or persistent changes in your stools, you should make an appointment to see your GP.

Reliable Ways to Relieve Constipation

You don't have to endure the discomfort. There are a number of safe, effective treatments designed to support your family’s digestive health and prevent recurrent issues.

  1. Make Changes to Your Daily Habits - Start by addressing any gaps in your fibre or fluid intake. Movement is also important; even a small increase in activity can significantly speed up "transit time."
  2. Gentle Support with Osmotic Laxatives - When lifestyle shifts aren't enough, try an osmotic laxative. These work by drawing water from the rest of your body into your bowel to soften the stool, making it much easier to pass. Options like Strigol Orange Flavour Powder (which contains macrogol) are excellent specialist-approved choices. Because they work with your body's natural hydration, they typically take 2 to 3 days to show full effect.
  3. Choosing the Right Softener - Other osmotic options include lactulose or polyethylene glycol. These are particularly useful if passing stools has become a painful experience for you or your child, as they focus specifically on the texture of the waste to prevent the need for straining.
  4. Targeted Solutions for Immediate Needs - For those times when you need relief now—rather than waiting a few days for an oral solution - glycerin suppositories provide a reliable, localised solution that works much faster.
  5. Seek Expert Guidance - If you find that these treatments aren't providing the relief you expect, seek help from your GP practice.

When to Speak to a Healthcare Professional

While occasional constipation is common, you should seek advice if you experience:

  • Constipation lasting more than three weeks
  • Severe abdominal pain
  • Blood in your stools
  • Unexplained weight loss
  • A sudden change in bowel habits

At 121 Pharmacy, our team is always available to offer discreet, friendly guidance.

Frequently Asked Questions

How long is it normal to be constipated?

Occasional constipation lasting a few days is common. If it continues for more than three weeks or becomes a regular issue, you should seek medical advice.

Can stress cause constipation?

Yes. Stress can affect the gut by slowing digestion and disrupting your normal bowel routine. Managing stress through relaxation techniques and regular exercise can help.

Is it safe to use laxatives regularly?

Laxatives can be very helpful for short-term relief. However, long-term use without medical supervision is not recommended. Always speak to a pharmacist or GP if you find yourself relying on them frequently.

What foods should I avoid if I am constipated?

Highly processed foods, excessive dairy, and low fibre foods may worsen symptoms. Reducing these while increasing fibre can help.

Can children experience constipation?

Yes, constipation is common in children, often due to diet, dehydration or reluctance to use unfamiliar toilets. If symptoms persist, consult a healthcare professional.

Does drinking coffee help with constipation?

For some people, coffee can stimulate bowel movements. However, too much caffeine can contribute to dehydration, which may worsen constipation. Balance is key.

Taking Control of Constipation for Better Digestive Health
