Dr John McGuinness, operating in Sydney’s Eastern Suburbs focuses on the diagnosis and treatment of conditions and injuries of the throat including loss of voice, throat infections, persistent tonsillitis and reflux.

Loss of Voice

There are a variety of medical conditions that can lead to voice problems. You should seek a consultation with Dr John McGuinness if you become hoarse frequently or notice voice change for an extended period of time. There are a range of non-surgical and surgical options to explore.

Persistent Tonsillitis

Part of your immune system, tonsils are two pads of glandular tissue in your throat that help fight infection. Reoccurring tonsillitis or strep, may lead to Dr John McGuinness to make a surgical recommendation for a tonsillectomy, the procedure to remove the tonsils.  After a tonsillectomy, patients don't have as many sore throats and breath and snoring problems


Gastroesophageal reflux disease, or GERD occurs when the lower oesophageal sphincter is weak or relaxes inappropriately, allowing the stomach's acidic contents to flow up into the oesophagus. Dietary and lifestyle choices may contribute to GERD. Certain foods and beverages, including chocolate, peppermint, fried or fatty foods, coffee, or alcoholic beverages, may trigger reflux and heartburn.

Depending on the severity of your GERD, treatment may involve lifestyle changes, medications, or surgery.
