月经失调指南：了解月经不规律及相关疾病

Overview

Inflammatory bowel disease (IBD) is a group of chronic disorders that cause long-term inflammation (irritation and swelling) in the digestive tract, the organ system that breaks down food and absorbs nutrients. The two most common types are Crohn’s disease, which can affect any part of the digestive tract from the mouth to the anus, and ulcerative colitis (UC), which only impacts the large intestine (colon) and rectum. IBD is not contagious, and with proper medical care, most people manage their symptoms and live full, active lives. It affects an estimated 3 million adults in the United States.

Signs & Symptoms

IBD symptoms vary depending on the type and severity of inflammation, and they often occur in cycles of flare-ups (when symptoms are active) and remission (when symptoms improve or disappear). Common symptoms include:

• Persistent diarrhea (loose, watery stools)
• Abdominal cramping and pain
• Blood in the stool
• Urgent, frequent need to have a bowel movement
• Unintended weight loss
• Ongoing fatigue
• Fever

Causes & Risk Factors

The exact cause of IBD is not fully known, but it is believed to stem from a combination of an overactive immune system that mistakenly attacks healthy digestive tract tissue, genetic predisposition (a family history of IBD increases your risk), and environmental triggers such as diet, stress, or certain medications. Common risk factors include a family history of IBD, being diagnosed before age 30 (though it can occur at any age), smoking (which increases Crohn’s disease risk and worsens symptoms), and regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, which can trigger flare-ups.

Diagnosis

There is no single test to diagnose IBD. Your healthcare provider will start with a physical exam, review your medical history, and rule out other conditions that cause similar symptoms. Common diagnostic steps include:

• Blood tests to check for anemia, inflammation, or infection
• Stool tests to rule out infections or other digestive issues
• Colonoscopy or sigmoidoscopy, where a thin, flexible tube with a camera is inserted into the rectum to view the colon and take small tissue samples (biopsies)
• Imaging tests such as CT scans, MRIs, or small bowel X-rays to check for inflammation or damage in the digestive tract

Treatment & Management

IBD treatment aims to reduce inflammation, prevent flare-ups, and improve quality of life. The right plan depends on your IBD type, symptom severity, and overall health. Common treatment options include:

• Medications: Anti-inflammatory drugs, immune system suppressors, biologics (medications that target specific parts of the immune system), and antibiotics to treat infections or complications
• Nutritional therapy: Special diets or feeding tubes to give the digestive tract a rest and reduce inflammation
• Surgery: For severe cases or complications (such as bowel blockages, fistulas, or increased cancer risk), surgery to remove damaged parts of the digestive tract may be necessary. For ulcerative colitis, surgery to remove the colon and rectum can cure the disease.

Living With It

While IBD is a lifelong condition, most people manage their symptoms effectively with consistent medical care and small lifestyle adjustments. Working closely with a gastroenterologist (a doctor who specializes in digestive health) and a registered dietitian can help you create a personalized plan to reduce flare-ups and improve your well-being.
