Your doctor may be able to see if you have external hemorrhoids simply by looking. Tests and procedures to diagnose internal hemorrhoids may include examination of your anal canal and rectum:
- Digital examination. During a digital rectal exam, your doctor inserts a gloved, lubricated finger into your rectum. He or she feels for anything unusual, such as growths. The exam can suggest to your doctor whether further testing is needed.
- Visual inspection. Because internal hemorrhoids are often too soft to be felt during a rectal exam, your doctor may also examine the lower portion of your colon and rectum with an anoscope, proctoscope or sigmoidoscope.
Your doctor may want to examine your entire colon using colonoscopy if:
- Your signs and symptoms suggest you might have another digestive system disease
- You have risk factors for colorectal cancer
- You're middle-aged and haven't had a recent colonoscopy
