Tonsillectomy May Lead To Weight Gain In Kids
(Ivanhoe Newswire) -- Children who undergo the surgical removal of their tonsils (tonsillectomy), with or without the removal of their adenoids (adenoidectomy), are at increased risk for becoming overweight after surgery, according to new research.
Childhood obesity has shot through the roof over the past two decades, with recent data suggesting that as many as 33 percent of American children are overweight and 17 percent obese. Obese children are at increased risk of becoming obese adults, thus making them susceptible to cardiovascular disease and diabetes.
The study sample included 795 children aged 0 to 18 years old, described as normal weight or overweight and who had tonsillectomy or adenotonsillectomy surgery. In 47.7 percent of patients, the primary reason for surgery was sleep-disordered breathing. The first group included three studies involving 127 children, whose body mass index (BMI) increased by 5.5-8.2%. The second group included three studies involving 419 patients, in whom the standardized weight scores increased in 46-100% patients. The third group included three studies with 249 patients, in whom 50 "“ 75% of the patients gained weight after adenoidectomy. Each study was designed with different definitions of overweight and a range of follow-up periods
"There may have been a variety of proposed mechanisms for the weight gain following adenoidectomy," author Anita Jeyakumar, MD was quoted as saying.
Based on these findings, the authors recommend that dietary and lifestyle advice be given to parents whose children are undergoing tonsillectomy. Growth monitoring after surgery is key to ensure that catch-up growth occurs within healthy limits.
