While generally safe,<unk>  may result in several complications, some of which are serious. Complications are divided into primary (first 24 hours after surgery), and secondary (after 24 hours), with bleeding being the most common complication. Other common complications are postoperative nausea and vomiting, dehydration, trouble eating, ear pain, taste dysfunction and trouble talking. In rare cases,<unk>  may also cause damage to the<unk> eth (because of the clamp that is placed in the mouth during surgery), larynx and pharyngeal wall, aspiration, respiratory compromise, laryngospasm, laryngeal edema and cardiac arrest. Throat pain typically lasts about one to two weeks after surgery. Significant post-operative primary bleeding occurs in 0.2–2.2% of people, and secondary bleeding in 0.1–3.3%. It is estimated 1.3% of people will have a delayed discharge (of 4 to 24 hours) due to a complication, and up to 3.9% will require repeat admission to hospital. The main reasons for either keeping a person in hospital, or readmitting them after<unk>  are uncontrolled pain, vomiting, fever, or bleeding. Death occurs as a result in between 1 in 2,360 and 56,000 procedures. Bleeding accounts for one-third of deaths. As the procedure is done under general anesthesia, there are anesthesia risks. Immune system There is no evidence<unk>  affects long<unk> rm immune function. It does not appear to affect the long<unk> rm risk of infections in other areas of the body. Some studies have found small changes in immunoglobulin concentrations after<unk>  but these are of unclear significance. The association between<unk>  and risk for inflammatory bowel disease (e.g., Crohn's disease or ulcerative colitis) is unclear. There is an association suggesting an increase in the risk of developing multiple sclerosis if done before the age of 20. A meta-analysis published in 2020 indicated a statistically significant association between a history of<unk>  and the development of Hodgkin's disease. The relationship between childhood<unk>  and the development of other cancer types in adulthood remains unclear.
