[68F] Experiencing muscle weakness and mild shortness of breath

What might be happening

Based on the information you've provided, possible diagnoses include:

• Chronic Obstructive Pulmonary Disease (COPD): This is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. It's commonly caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. Symptoms include breathing difficulty, cough, mucus (sputum) production, and wheezing.

  • Treatment typically involves medications to help manage symptoms, pulmonary rehabilitation, and in severe cases, oxygen therapy or surgery.

• Myasthenia Gravis: This is a chronic autoimmune neuromuscular disease that causes weakness in the skeletal muscles, which are responsible for breathing and moving parts of the body, including the arms and legs. Symptoms include muscle weakness that improves with rest and worsens with activity.

  • Treatment typically involves medications to help manage symptoms, physical therapy, and in some cases, surgery.

• Peripheral Artery Disease (PAD): This is a common circulatory problem in which narrowed arteries reduce blood flow to your limbs. When you develop peripheral artery disease, your extremities — usually your legs — don't receive enough blood flow to keep up with demand. This causes symptoms, most notably leg pain when walking (claudication).

  • Treatment typically involves lifestyle changes, medications, and in some cases, angioplasty or surgery.

What you can do

It would be best to consult a doctor about your symptoms so that they can provide a formal assessment and order relevant tests if necessary. In the meantime, you can try the following to manage your symptoms:

1. Stop smoking: This is the most important step you can take to slow the progression of COPD and improve your symptoms.
2. Exercise regularly: Regular physical activity can help improve your muscle strength and boost your overall feelings of well-being.
3. Eat a healthy diet: A diet rich in fruits, vegetables, lean proteins, and whole grains can help improve your overall health and energy levels.
4. Rest and avoid overexertion: If you have Myasthenia Gravis, rest and avoiding overexertion can help manage your symptoms.

What you should look out for

Reasons to see a doctor more urgently:

• If your symptoms worsen or you develop new symptoms
• If you experience severe shortness of breath or chest pain
• If you have difficulty swallowing or changes in your vision
