Muscle weakness can be caused by a variety of factors, such as injury, disease, aging, or inactivity. Some common medical conditions that can cause muscle weakness include:
- Muscular dystrophy: a group of genetic disorders that cause progressive muscle weakness and degeneration.
- Multiple sclerosis: a disease that affects the central nervous system and can cause muscle weakness, fatigue, and difficulty with coordination.
- Parkinson's disease: a degenerative disorder that affects the nervous system and can cause tremors, rigidity, and muscle weakness.
- Myasthenia gravis: an autoimmune disorder that affects the communication between nerves and muscles, leading to muscle weakness and fatigue.
- Hypothyroidism: an underactive thyroid gland can cause muscle weakness and fatigue.
- Infections: certain viral and bacterial infections can cause muscle weakness and fatigue, such as influenza, Lyme disease, and HIV/AIDS.
If you are experiencing muscle weakness, it is important to speak with a healthcare professional to determine the underlying cause and receive appropriate treatment.
