Understanding Diverticulitis
Diverticulitis is a prevalent condition that affects the colon. It occurs when small pouches, called diverticula, form in the lining of the digestive tract and become inflamed or infected. These diverticula are more commonly found in the lower part of the colon, known as the sigmoid colon. While diverticula themselves are usually harmless and asymptomatic, when they become inflamed, it can lead to symptoms ranging from mild discomfort to severe abdominal pain.
Typical symptoms of diverticulitis include:
- Abdominal pain, often localized in the lower left side
- Tenderness in the affected area
- Fever and chills
- Nausea and vomiting
- Changes in bowel habits, such as diarrhea or constipation
Several risk factors can increase the likelihood of developing diverticulitis. These include:
- Age, as the incidence of diverticulitis tends to increase with age
- A low-fiber diet, which can contribute to the formation of diverticula
- A sedentary lifestyle
- Obesity
- Smoking
To diagnose diverticulitis, healthcare providers often rely on imaging tests, such as ultrasound, to visualize any abnormalities in the colon. Ultrasound imaging for diverticulitis diagnosis offers a non-invasive and safe approach to evaluate the condition. It utilizes sound waves to create real-time images of the colon, providing valuable insights into the presence and severity of diverticulitis.
During an ultrasound examination for diverticulitis, the healthcare professional will carefully scan the lower abdomen using a transabdominal approach.
