How long does nasal congestion last after a tonsillectomy and adenoidectomy?

Nasal congestion after a tonsillectomy and adenoidectomy can last for about one to two weeks as the body heals. This congestion is often due to swelling and the body's response to surgery. In some cases, it may persist a bit longer, especially if there are residual effects or if the sinuses are affected. If congestion lasts beyond a couple of weeks or worsens, it's advisable to consult a healthcare professional.
