7 Causes of Constipation Explained by a Doctor

Constipation is one of the most common digestive complaints worldwide, yet it's often misunderstood. While most people experience it occasionally, chronic constipation can significantly impact quality of life.

1. Inadequate Fibre Intake

The average Nigerian diet has shifted significantly over the past decade. With the rise of processed foods and fast dining, many young adults are consuming far less fibre than the recommended 25-30g per day. Fibre adds bulk to your stool and helps it move through your digestive tract more efficiently.

What to do: Incorporate more whole grains, fruits, vegetables, and legumes into your meals. Nigerian staples like beans, plantain, and leafy vegetables are excellent sources.

2. Dehydration

Water is essential for softening stool. When you're dehydrated, your colon absorbs more water from the stool, making it hard and difficult to pass. In hot climates like Nigeria, staying hydrated requires conscious effort.

What to do: Aim for at least 2-3 litres of water daily. More if you're active or in hot weather.

3. Sedentary Lifestyle

Physical activity stimulates intestinal contractions that help move stool through your system. Sitting for long hours — whether at work or scrolling through social media — can slow things down.

What to do: Even a 30-minute daily walk can make a noticeable difference. Try to break up long sitting periods with movement.

4. Ignoring the Urge

When you consistently delay going to the bathroom — because you're busy, in public, or just don't feel like it — your body can eventually stop sending those signals as strongly.

What to do: When nature calls, answer. Try to establish a regular bathroom routine, ideally after meals when your digestive system is most active.

5. Stress and Anxiety

Your gut and brain are directly connected through the gut-brain axis. High stress levels can disrupt normal digestive function, either speeding things up or slowing them down considerably.

What to do: Incorporate stress management techniques like deep breathing, meditation, or regular exercise into your routine.

6. Certain Medications

Pain relievers (especially opioids), antacids containing calcium or aluminium, iron supplements, and some blood pressure medications can cause constipation as a side effect.

What to do: Never stop prescribed medication without consulting your doctor. Instead, discuss alternatives or supplementary strategies to manage this side effect.

7. Underlying Medical Conditions

Conditions like hypothyroidism, diabetes, irritable bowel syndrome (IBS), and neurological disorders can all contribute to chronic constipation.

What to do: If constipation persists despite lifestyle changes, see a healthcare professional for proper evaluation.

The Bottom Line

Most cases of constipation can be resolved with simple lifestyle modifications. Focus on hydration, fibre intake, regular movement, and stress management. If symptoms persist beyond three weeks, consult a healthcare provider to rule out underlying conditions.
