Diverticular Disease - November 2021 Insights
Understanding Diverticular Disease
Diverticular disease encompasses two related conditions: diverticulosis and diverticulitis. Diverticulosis is the formation of small pouches (diverticula) in the lining of the intestine. It becomes diverticulitis when these pouches become inflamed or infected. This condition primarily affects the large intestine (colon).
Prevalence in the United Kingdom
In the UK, diverticular disease is a common condition, especially among older adults. Studies suggest that over 50% of people aged 60 and above may develop diverticulosis, although many remain asymptomatic. The incidence of diverticulitis, more severe and symptomatic, is also notable among this demographic.
Causes and Risk Factors
The exact cause of diverticular disease is not entirely understood. However, several factors may contribute, including a low-fibre diet, aging, obesity, and a sedentary lifestyle. The Western diet, which is often low in fibre, is particularly linked to higher rates of the disease.
Symptoms and Diagnosis
Diverticular disease symptoms can range from mild to severe. Common symptoms include abdominal pain, bloating, changes in bowel habits, and, in the case of diverticulitis, fever, and chills. Diagnosis is typically achieved through medical imaging such as a CT scan, alongside a clinical evaluation.
Treatment and Management
Treatment for diverticular disease varies depending on severity. For asymptomatic diverticulosis, a high-fibre diet is often recommended to prevent progression. In the case of diverticulitis, antibiotics and a clear-liquid diet may be prescribed. Severe cases might necessitate surgical intervention.
Prevention Strategies
Preventing diverticular disease involves adopting a healthy lifestyle. Ensuring an adequate intake of fibre through fruits, vegetables, and whole grains is crucial. Regular physical activity, maintaining a healthy weight, and avoiding smoking also play significant roles in prevention.
Conclusion
Diverticular disease is a significant health concern in the UK, particularly among older adults. Understanding its causes, symptoms, and treatment options is essential for managing and preventing this condition effectively. With appropriate dietary and lifestyle changes, individuals can reduce their risk and improve their overall digestive health.
Frequently Asked Questions
What is diverticular disease?
Diverticular disease occurs when small bulges or pockets (diverticula) form in the lining of the intestine. It is common in people over the age of 40.
What causes diverticular disease?
The exact cause of diverticular disease is not known, but it is believed to be linked to a low-fibre diet, which leads to hard stools and increased pressure on the colon.
What are the symptoms of diverticular disease?
Symptoms can include abdominal pain, bloating, constipation, and diarrhoea. In some cases, people may experience rectal bleeding.
How is diverticular disease diagnosed?
Diagnosis is typically made through a combination of medical history, physical examination, and imaging tests such as a CT scan or colonoscopy.
Is diverticular disease the same as diverticulitis?
No, diverticular disease refers to the presence of diverticula. Diverticulitis occurs when these diverticula become inflamed or infected.
What treatments are available for diverticular disease?
Treatment may include a high-fibre diet, pain relief medication, and antibiotics if an infection is present. Severe cases might require surgery.
Can diverticular disease be prevented?
A diet high in fibre, regular exercise, and staying hydrated can help reduce the risk of developing diverticular disease.
What should I eat if I have diverticular disease?
A diet rich in fruits, vegetables, whole grains, and legumes is recommended. Avoiding nuts and seeds is no longer generally advised.
Are there complications associated with diverticular disease?
Yes, complications can include diverticulitis, abscesses, fistulas, bowel obstructions, and in rare cases, peritonitis.
How common is diverticular disease in the UK?
Diverticular disease is relatively common, particularly in older adults. About 5% of the UK population under 40, and 50% above 60, are affected.
Can diverticular disease lead to cancer?
Diverticular disease itself does not lead to cancer, but symptoms can sometimes be similar to those of colorectal cancer, so proper diagnosis is important.
Is surgery always required for diverticular disease?
Surgery is not always required and is typically considered for severe or recurrent cases that do not respond to medical treatment.
Can lifestyle changes improve diverticular disease?
Yes, increasing dietary fibre, drinking plenty of fluids, and regular physical activity can help manage the symptoms of diverticular disease.
Is diverticular disease hereditary?
There is evidence to suggest a genetic component, as diverticular disease can run in families, but lifestyle factors also play a significant role.
When should I seek medical attention for diverticular disease?
You should seek medical attention if you experience severe abdominal pain, fever, vomiting, rectal bleeding, or any significant changes in bowel habits.
