Guillain-Barré Syndrome (GBS)
Introduction
Guillain-Barré Syndrome (GBS) is a rare and severe neurological disease that involves the peripheral nervous system. It takes place when the immune system of the body, in error, attacks the nerves, causing numbness, weakness of muscles, and paralysis.
GBS can happen to anyone of any age, but it is more prevalent among adults. The cause is not definitely known, but it is usually preceded by viral or bacterial infections. The earlier the diagnosis and treatment, the greater the chances of recovery, as advanced cases can result in respiratory failure.
In this blog, everything you should know regarding Guillain-Barré Syndrome, from causes to symptoms to diagnosis to treatment to prevention, will be addressed.
What Causes Guillain-Barré Syndrome?
Guillain-Barré Syndrome (GBS) happens when the immune system attacks the myelin sheath, which covers nerve fibers. This damages nerves and impairs communication between the brain and muscles.
While the cause is not known, some triggers can raise the risk of developing GBS:
1. Viral and Bacterial Infections
The majority of GBS cases follow an infection. Some common infections associated with GBS are
- Campylobacter jejuni (a bacterium in contaminated food)
- Influenza (flu virus)
- Epstein-Barr virus (EBV)
- Cytomegalovirus (CMV)
- Zika virus
- COVID-19
2. Recent Vaccination or Surgery
Sometimes, in some individuals, GBS occurs following vaccination or surgery, but it is extremely rare.
3. Autoimmune Disorders
Individuals with other autoimmune disorders are more likely to develop Guillain-Barré Syndrome.
Symptoms of Guillain-Barré Syndrome
The symptoms of GBS begin suddenly and advance rapidly. The common symptoms are:
1. Weakness and Tingling Sensation
Starts in the legs and feet and spreads to the arms and upper limbs.
Described by some patients as a “pins and needles” feeling.
2. Muscle Weakness and Loss of Reflexes
- The weakness may advance to total paralysis in bad cases.
- Reflexes, like knee jerks, may vanish.
3. Difficulty Walking and Moving
- Walking is affected by weakness of muscles and lack of coordination.
- Some individuals require assistance to stand or walk.
4. Pain and Cramping
- Severe pain in nerves, particularly in the back and legs.
- Muscle spasms and cramps are frequent.
5. Trouble Breathing and Swallowing
- In advanced cases, GBS involves the muscles used for breathing.
- A few patients need a ventilator to help with breathing.
6. Heart Rate and Blood Pressure Abnormalities
- GBS can lead to irregular heart rate and blood pressure.
7. Bladder and Bowel Issues
- Trouble urinating or loss of bowel control may happen.
- If you feel sudden tingling or weakness that moves rapidly, get immediate medical attention.

Types of Guillain-Barré Syndrome
GBS has various subtypes, each of which affects the nerves in a different way.
1. Acute Inflammatory Demyelinating Polyneuropathy (AIDP)
The most prevalent type of GBS.
- It destroys the myelin sheath, which slows down the nerve impulses.
- Produces muscle weakness, numbness, and paralysis.
2. Miller Fisher Syndrome (MFS)
- A rare type that mostly involves the eyes and balance.
- Produces double vision, lack of coordination, and unsteadiness in walking.
3. Acute Motor Axonal Neuropathy (AMAN) and Acute Motor Sensory Axonal Neuropathy (AMSAN)
- More prevalent in Latin America and Asia.
- Causes severe weakness in muscles and loss of reflexes.
How Is Guillain-Barré Syndrome Diagnosed?
As GBS signs and symptoms can be similar to other neurological disorders, physicians apply tests to ascertain the diagnosis.
Neurological Exam: Tests for muscle strength, reflexes, and coordination.
Lumbar Puncture (Spinal Tap): Examines cerebrospinal fluid for excess proteins.
Electromyography (EMG): Tests the electrical activity in muscles and nerves.
Nerve Conduction Studies (NCS): Checks nerve function by evaluating signal transmission.
Blood Tests: Excludes other causes such as infections or vitamin deficiency.
Early detection is important to avoid complications and initiate treatment early.
Treatment of Guillain-Barré Syndrome
There is no treatment for GBS, but early treatment can hasten recovery and decrease complications.
1. Hospitalization and Monitoring
- The majority of individuals with GBS require hospitalization to be monitored for breathing, heart rate, and nerve function.
- Severe cases need a ventilator for breathing support.
2. Plasma Exchange (Plasmapheresis)
- Removes toxic antibodies from the blood to minimize nerve damage.
- Aids in shortening recovery time.
3. Intravenous Immunoglobulin (IVIG) Therapy
- A therapy that prevents immune system attacks on nerves.
- It is as effective as plasma exchange but less cumbersome.
4. Pain Management
- Painkillers and anti-inflammatory medications alleviate nerve pain.
- Physical therapy also enhances muscle strength.
5. Rehabilitation and Physical Therapy
- Following the acute phase, rehabilitation restores movement and coordination.
- Exercises enhance muscle strength, balance, and mobility.
Recovery and Prognosis
The majority of individuals improve within 6 to 12 months, yet complete recovery in severe cases can take years.
- 80% gain normal walking strength within 6 months.
- 60% regain a full muscle recovery after one year.
- 5-10% suffer from long-standing weakness or complications.
Early treatment enhances the opportunity for a full recovery.
Preventing Guillain-Barré Syndrome
There is no surefire way to prevent GBS, but there are some measures that can reduce the risk:
Maintain Good Hygiene: Regular hand washing to avoid infections.
Avoid Contaminated Food: Avoid bacterial infections such as Campylobacter.
Get Vaccinated: Influenza and COVID-19 vaccines minimize viral infections associated with GBS.
Seek Early Treatment: Treat infections and diseases early. https://theechowriters.com/category/health-and-fitness/
Conclusion
Guillain-Barré Syndrome is a serious but manageable neurological disorder. Prompt diagnosis and treatment can enhance outcomes and hasten recovery. https://my.clevelandclinic.org/health/diseases/15838-guillain-barre-syndrome If you have sudden weakness or paralysis of the muscles, get immediate medical help.
With appropriate medical intervention, rehabilitation, and lifestyle modification, the majority of individuals with GBS are able to recover normal function and live a healthy life.
