Is anal itching a sign of having worms?

Generally, whether anal itching is caused by parasites needs to be determined based on specific symptoms and medical examinations. If discomfort persists, it is recommended to seek medical attention promptly. The detailed analysis is as follows:

If anal itching worsens at night, becomes more intense after scratching, and there are no obvious red patches or rashes around the anus, but some individuals also experience abdominal pain, poor appetite, or notice small white worms in their stool, and parasite eggs are detected through routine stool examination, this can be diagnosed as a parasitic infection.

If anal itching mainly occurs during the day, accompanied by redness, rashes, flaking skin, or lichenification around the anus, without symptoms such as abdominal pain or appetite changes, and no worms are seen in the stool nor parasite eggs found in stool tests, then the itching may be related to eating spicy foods, wearing tight and non-breathable underwear, moisture around the anus, or anorectal conditions—such cases are not due to parasitic infection.

Daily care should include keeping the anal area clean and dry; wash with warm water after bowel movements and avoid vigorous wiping. Wear loose, breathable cotton underwear, change it daily, and sun-dry for disinfection. Maintain a light diet, avoid spicy and irritating foods, and consume more fresh fruits and vegetables. Avoid scratching the anal area with hands to prevent skin damage and infection. Establish regular bowel habits, maintain smooth bowel movements, and reduce the likelihood of anorectal diseases triggering itching.
