Myasthenia Gravis: Causes, Symptoms, Treatment, and Daily Life Tips

Myasthenia Gravis (MG) is a chronic autoimmune neuromuscular disorder that leads to varying degrees of skeletal muscle weakness. This condition can affect the eyes, face, throat, and limbs, significantly impacting daily life. Early diagnosis and proper treatment can help manage the symptoms effectively.

What is Myasthenia Gravis?

Myasthenia Gravis is an autoimmune condition where the immune system produces antibodies that block or destroy acetylcholine receptors at the neuromuscular junction. This impairs the communication between nerves and muscles, leading to muscle weakness and fatigue.

Causes of Myasthenia Gravis

• Autoimmune Response: The body attacks its own tissues.
• Thymus Gland Abnormalities: Often linked to thymomas or hyperplasia.
• Genetic Factors: In rare cases, it may run in families.
• Other Autoimmune Disorders: Such as lupus or rheumatoid arthritis.

Symptoms of Myasthenia Gravis

• Drooping eyelids (ptosis)
• Double vision (diplopia)
• Difficulty swallowing or speaking
• Weakness in arms, legs, or neck
• Shortness of breath
• Fluctuating muscle fatigue that worsens with activity

How is Myasthenia Gravis Diagnosed?

• Physical and Neurological Exams
• Blood Tests for antibodies (AChR, MuSK)
• Electromyography (EMG)
• CT or MRI scans to check the thymus gland
• Edrophonium Test (Tensilon test)

Treatment Options

1. Medications:

• Acetylcholinesterase Inhibitors (e.g., Pyridostigmine)
• Corticosteroids to suppress immune response
• Immunosuppressants like azathioprine or cyclosporine

2. Surgical Treatments:

• Thymectomy – removal of the thymus gland

3. Advanced Therapies:

• Plasmapheresis (Plasma Exchange)
• Intravenous Immunoglobulin (IVIG)

Lifestyle and Self-Care Tips

• Plan activities with rest breaks
• Avoid stress and infections
• Wear eye patches for double vision
• Maintain a healthy diet to boost immunity
• Use assistive devices for mobility support
