Diverticular Disease

Diverticular disease is a digestive condition where small pouches (diverticula) form in the bowel. Most people come to this page looking for safe, pharmacy-led support for day-to-day symptoms such as bloating and wind, lower tummy discomfort, and changes in bowel habits including constipation or short-lived diarrhoea. For many, the aim is practical symptom relief alongside steady routine changes—gradually increasing fibre, drinking enough fluids, and supporting regular bowel movements—without triggering more discomfort.

Shop by diverticular disease type

Popular types of products

  • Fibre support formats (powders, granules or sachets) to help maintain regular bowel habits
  • Constipation relief options (format varies by product) for short-term support when stools are hard or infrequent
  • Anti-wind support (tablets/capsules) for bloating and trapped wind discomfort
  • Oral rehydration sachets to help replace fluids and salts if you have looser stools
  • Convenient dosing formats such as capsules, tablets or liquids to suit your routine

How to choose the right option

  • Start with your main symptom: constipation, bloating/wind and diarrhoea usually need different approaches.
  • Increase fibre slowly: sudden increases can worsen wind and bloating; build up gradually over days to weeks.
  • Prioritise hydration: fibre products and constipation treatments work best with adequate fluids.
  • Choose a format you’ll take correctly: sachets vs tablets vs liquids depending on preference and routine.
  • Check suitability and interactions: review age guidance, pregnancy/breastfeeding advice, allergies and other medicines.
  • Know when to stop self-treating: severe pain, fever, vomiting, blood in stools, or dehydration need urgent medical advice.

FAQs

What’s the difference between diverticular disease and diverticulitis?

Diverticular disease usually refers to having diverticula and symptoms such as bloating or changes in bowel habit. Diverticulitis is when the pouches become inflamed or infected and is more likely to cause worsening abdominal pain, fever and feeling unwell, and should be assessed promptly.

There are no products listed on this page—where should I start?

Start with the range that matches your main symptom, such as constipation relief medicines or diarrhoea relief and rehydration support. If you’re not sure what’s suitable for you, a pharmacist can help you choose safely.

Are fibre supplements suitable for diverticular disease?

Many people use fibre supplements to support regular bowel movements, especially if dietary fibre is low. Increase fibre gradually and drink plenty of fluids. If fibre worsens pain, marked bloating or symptoms change, seek pharmacist or GP advice.

How quickly should I increase fibre?

Increase fibre slowly over days to weeks so your gut can adjust. Keep fluid intake up. If you get worsening pain, significant bloating, or persistent changes in bowel habits, speak to a pharmacist or GP before continuing.

What should I consider when choosing a constipation product?

Check who the product is suitable for, how it should be taken and how quickly it works. Avoid self-treating if constipation is new, persistent or keeps returning, or if you have severe abdominal pain, unexplained weight loss, or blood in stools—get medical advice.

Can I use anti-diarrhoea medicines if my bowel habit fluctuates?

Anti-diarrhoea medicines may be appropriate for short-term diarrhoea in adults, but avoid self-treatment if you have fever, blood in stools, severe pain, or symptoms that keep returning. Consider rehydration support and ask a pharmacist what’s suitable.

When should I contact a GP or NHS 111?

Seek urgent advice if you develop severe or worsening abdominal pain (especially on the left side), fever, vomiting, blood in stools, faintness, or signs of dehydration. If you’re older, pregnant, immunocompromised, or have other bowel conditions, get advice sooner.

Important: This information supports general product choice and is not a substitute for medical advice. Always read the label or patient information leaflet and follow dosing instructions. If symptoms are severe, persistent or worsening, or you suspect diverticulitis, speak to a pharmacist, contact your GP or NHS 111, or seek urgent care.
