Tonsillectomy, the surgical removal of the tonsils, is a common procedure performed for various reasons, ranging from recurrent throat infections to sleep-disordered breathing. While the primary goal of a tonsillectomy is to improve health and well-being, some patients and researchers have observed potential effects on body weight following the procedure. This article delves into the intricate relationship between tonsillectomy and weight loss, considering both adult and pediatric populations, and addressing common misconceptions.
Weight Loss After Tonsillectomy in Adults: Initial Observations
Anecdotal evidence suggests that some adults experience weight loss in the immediate postoperative period after a tonsillectomy. Some patients report a 10- to 15-pound weight loss. A retrospective study using data from adult tonsillectomies performed between 2008 and 2013 revealed a statistically significant difference between preoperative and postoperative weight, with an average weight loss of 4.77 pounds (P < .005). The study also found that the highest amount of weight loss was observed in the oldest population group (5.72 pounds in subjects aged >40 years, 4.95 pounds in 31- to 40-year-olds, and 5.44 pounds in 20- to 30-year-olds, P = .03). These age comparisons were statistically significant. However, the study also indicated that this weight loss is typically followed by a return to baseline weight after roughly 5 months.
One individual shared their personal experience of undergoing a tonsillectomy and adhering to a diet of clear liquids, Jell-O, popsicles, and occasionally scrambled eggs due to the pain. This resulted in a calorie intake of no more than 600 calories a day and a weight loss of ten pounds. They recognized that the initial weight loss was likely due to water loss but were hopeful about using it as a starting point for a healthier eating pattern.
Factors Contributing to Postoperative Weight Loss in Adults
Several factors can contribute to weight loss following a tonsillectomy in adults:
- Reduced Caloric Intake: Postoperative pain and difficulty swallowing can significantly reduce a patient's appetite and ability to consume solid foods. The initial days after surgery often involve a diet of clear liquids, which is very low in calories.
- Fluid Loss: The body's natural response to surgery and inflammation can lead to fluid loss, contributing to a temporary decrease in weight.
- Metabolic Changes: Surgical stress can temporarily alter metabolic processes, potentially affecting weight.
Importance of a Balanced Perspective
It is crucial to recognize that the weight loss experienced immediately after a tonsillectomy is often temporary and primarily due to fluid loss and reduced caloric intake. It is generally not a sustainable or healthy method for long-term weight management. Patients should prioritize proper hydration and nutrition to support healing and recovery.

Adenotonsillectomy and Weight Changes in Children: Addressing Misconceptions
In the past, it was commonly believed that adenotonsillectomy (removal of both tonsils and adenoids) in children, particularly those with mild sleep-disordered breathing, could lead to undesirable weight gain. However, recent research has challenged this notion.
Challenging the Assumption of Weight Gain
A study examining data from the Pediatric Adenotonsillectomy Trial for Snoring (PATS) found that adenotonsillectomy did not result in a statistically significant increase in undesirable weight gain in children with mild sleep-disordered breathing. The PATS trial included 458 children with mild sleep-disordered breathing, randomized into two groups: those who underwent adenotonsillectomy and those who received “watchful waiting with supportive care.” Undesirable weight gain occurred after 12 months in 32% of cases from the adenotonsillectomy group (120 children), versus 27% of the watchful waiting group (101 children). A regression analysis did not find a significant association between adenotonsillectomy and undesirable weight gain.
Interrelation of Weight and Sleep-Disordered Breathing in Children
Weight and sleep-disordered breathing in children are closely related. Children with obesity are more likely to develop symptoms of sleep-disordered breathing. Conversely, underweight children who are failing to thrive due to their sleep-disordered breathing may experience a desired weight gain after adenotonsillectomy. This "catch-up" weight gain in underweight children may have contributed to the earlier perception that adenotonsillectomies could cause undesirable weight gain.
Factors to Consider
Several factors can influence weight changes after adenotonsillectomy in children:
- Improvement in Sleep Quality: Adenotonsillectomy can improve sleep quality, potentially leading to increased physical activity and improved metabolism.
- Increased Appetite: Resolution of sleep-disordered breathing can lead to increased appetite and improved food intake.
- Underlying Weight Status: Overweight children are likely to continue gaining weight regardless of whether they undergo adenotonsillectomy. Underweight children may experience "catch-up" growth after surgery.
Implications for Clinicians and Families
Clinicians should be aware that adenotonsillectomy is not necessarily an independent risk factor for undesirable weight gain in children. However, it is essential to monitor children's weight after surgery and encourage healthy weight management strategies, especially in overweight children.

General Considerations After Tonsillectomy
Regardless of age, several general considerations apply to patients recovering from a tonsillectomy:
Recovery Period
Young patients will typically require 10-14 days of recovery. Most children will be out of school for 1-2 weeks.
Postoperative Care
- Hydration: It is very important that patients drink plenty of fluids, such as water and apple juice, to recover quickly.
- Diet: Patents should not worry about calories or nutrition for the first two weeks after surgery.
- Pain Management: The first few days after surgery there tends to be less pain. The swelling of the surgical area has not yet happened, therefore no pain is felt.
- Common Symptoms: Sometimes, patients vomit after surgery, but vomiting should cease about 24 hours after surgery. It is not unusual to have a low grade fever. Many parents become concerned when their child continues to snore after surgery. Especially if the reason for surgery was to correct loud snoring and obstructive breathing. Don’t worry it is very normal for your child to continue to snore for several days after surgery because of swelling. When the swelling resolves you will frequently see that your child no longer snores. Scabs in the area where the tonsils and adenoids were removed will appear white and cause bad breath. They will often break away in pieces about a week after surgery. Children will often complain of ear pain after tonsillectomy. Sometimes the ears actually hurt more than the throat even thought the ears were not operated on.
