Common Culprits: Everyday Causes of Muscle Weakness

Sometimes, muscle weakness has simple explanations. Overexertion during exercise, lack of sleep, or poor nutrition can lead to temporary weakness. Dehydration and electrolyte imbalances can also affect muscle function. In many cases, addressing these lifestyle factors can resolve the weakness.

Medical Conditions That Cause Muscle Weakness

Numerous medical conditions can cause muscle weakness. These include muscle diseases like muscular dystrophy, inflammatory conditions like polymyositis, and neurological disorders such as multiple sclerosis or myasthenia gravis. Endocrine disorders, particularly thyroid problems, can also lead to muscle weakness. Some infections and certain medications may affect muscle strength as well.
Muscle weakness refers to a lack of muscle strength, which can result from a variety of causes, including temporary fatigue, lifestyle factors, and serious medical conditions.

When Nerves Are to Blame

Sometimes, the problem isn't in the muscles themselves, but in the nerves that control them. Conditions like peripheral neuropathy, amyotrophic lateral sclerosis (ALS), or pinched nerves can cause weakness by disrupting the signals between the brain and muscles. Understanding whether the weakness is due to a muscle or nerve problem is crucial for proper diagnosis and treatment.
