What Is Guillain-Barré Syndrome (GBS) And How Can It Be Identified ?

Pune, March 6, 2026: Health authorities are closely monitoring cases of Guillain‑Barré Syndrome (GBS) after several patients were reported in Pune last year, raising concerns among residents and medical experts. The rare neurological disorder can cause muscle weakness, nerve damage and, in severe cases, paralysis, making early detection and treatment crucial.

What Is Guillain-Barré Syndrome?

Guillain-Barré Syndrome is an autoimmune neurological disorder in which the body’s immune system mistakenly attacks the peripheral nerves. These nerves are responsible for carrying signals between the brain, spinal cord and the rest of the body.

Doctors explain that nerves are protected by a layer called the myelin sheath, which helps signals travel quickly. In patients with GBS, the immune system damages this protective layer, slowing or blocking nerve signals. As a result, muscles may become weak or stop functioning properly.

What Causes GBS?

The exact cause of Guillain-Barré Syndrome is still not fully understood. However, medical experts say it is often triggered by infections such as:

• Influenza or common cold
• Stomach infections or diarrhoea
• Certain bacterial infections such as Campylobacter jejuni
• Viral infections like norovirus
• In rare cases, vaccination

Doctors say symptoms typically appear four to six weeks after a prior infection, when the immune system mistakenly attacks the nerves.

How To Identify Symptoms

Health experts say early symptoms usually begin in the legs and feet and gradually spread to other parts of the body. The most common warning signs include:

• Tingling or numbness in hands and feet
• Muscle weakness, especially in the legs
• Difficulty walking or climbing stairs
• Loss of reflexes
• Severe fatigue
• Trouble breathing in serious cases
• Paralysis in arms or legs

As the condition progresses, symptoms may worsen quickly, which is why GBS is considered a medical emergency and often requires hospitalisation.

Treatment and Recovery

Doctors say most patients can recover with timely medical treatment. Treatment usually includes immunoglobulin therapy, which helps control the immune system, and ventilator support for patients who develop breathing problems.

Medical experts estimate that about 5% of patients diagnosed with GBS may not survive, while others may take weeks or months to recover. Some patients may also experience long-term nerve damage.

Why Awareness Matters

Health officials say recognising early symptoms and seeking immediate medical attention can significantly improve outcomes. Experts also emphasise the importance of safe drinking water, good sanitation and proper food hygiene, as infections linked to contaminated food or water may increase the risk of developing GBS.

Authorities continue to monitor the situation while urging people to consult doctors immediately if they experience sudden muscle weakness, tingling sensations or difficulty breathing.
