How long does it take to recover swallowing function in Guillain-Barré syndrome?

In Guillain-Barré syndrome, swallowing function usually starts to recover after 3 weeks of the onset of the disease, and the majority of patients recover within two months to one year, while about 10% of the patients recover poorly and leave serious sequelae, and the specific recovery time varies depending on the patient’s own condition.
Guillain-Barré syndrome is an immune-mediated peripheral neuropathy with an acute or subacute onset, peaking at about 2 weeks and recovering within weeks to months, with the vast majority of patients beginning to improve in about 3 weeks and gradually returning to normal within 2 months to a year.
The recovery time of swallowing function also depends on the individual differences of patients, such as age greater than 60 years old, longer hospitalization, previous gastrointestinal diseases, mechanical ventilation, etc. The overall prognosis is worse, the recovery time is longer, and even about 10% of patients can not be recovered and left with serious sequelae.
It is recommended that patients start swallowing rehabilitation training as early as possible, and should consult a doctor in time if they have any discomfort, and standardize the treatment under the guidance of a physician.
