Hello, Misconception abounds about tonsillectomy. But all the rumours you may hear are baseless. Recurrent sore throat in a kid is very debilitating, it hampers the health as well as the performance of the child. The most common cause of it in a kid is chronic tonsillitis. It is due to streptococcal infection (usually). And the complications of chronic tonsillitis are so problematic later in life that going for tonsillectomy of your kid is the Golden option . Rest assured, there is no such problem after tonsillectomy. Instead, there is a marked improvement in the quality of life ! Regarding weight gain, you might have noticed that your child declines food during attacks of tonsillitis and that her appetite is decreasing day by day. What happens after tonsillectomy is that the child has a feeling of wellness after a long period of time, so she enjoys eating. This leads to an apparent weight gain, which in fact is the return of her normal weight. And yes, recurrent sore throat is depressing, not its treatment. Don t you worry. Go for tonsillectomy of your kid. She ll thank you for this decision of yours. Take care.
