Weakness (कमजोरी) is a symptom of many different medical conditions. The causes are many and can be divided into conditions with true or perceived muscle weakness. True muscle weakness is a primary symptom of various skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy. It occurs in neuromuscular junction disorders, such as myasthenia gravis. Weakness is a common symptom that can affect individuals of all ages, often signaling an underlying health concern. It is characterized by a lack of physical or muscular strength, making it difficult to perform daily activities. It can be temporary, resulting from factors like fatigue, dehydration, or illness, or it can be chronic, associated with conditions such as anemia, neurological disorders, or metabolic imbalances.
Weakness Meaning
Weakness is characterized by a lack of physical or muscular strength, making it difficult to move or perform daily activities. Fatigue, illness, nutritional deficiencies, or underlying medical conditions can cause it. Weakness can also refer to a lack of mental or emotional strength, such as difficulty coping with stress or challenges. In a medical context, it may indicate an issue with the muscles, nerves, or overall energy levels in the body.

Weakness Types
It can be classified into different types based on its cause and effect on the body. The main types include:
Muscular Weakness (True Weakness)
This occurs when the muscles physically lose strength and cannot function properly. It can be caused by:
- Neuromuscular disorders (e.g. muscular dystrophy, multiple sclerosis)
- Infections (e.g. polio, myositis)
- Autoimmune diseases (e.g. myasthenia gravis)
- Muscle atrophy due to lack of use or aging
Generalized Weakness
A feeling of overall body fatigue or exhaustion rather than a specific muscle weakness. Common causes include:
- Anemia (low red blood cell count)
- Chronic illnesses (e.g. diabetes, kidney disease)
- Nutritional deficiencies (e.g. lack of iron, vitamin B12, or potassium)
- Infections (e.g. flu, COVID-19)
Fatigue-Related Weakness
A temporary loss of strength due to overexertion or lack of rest. Causes include:
- Lack of sleep
- Dehydration
- Poor diet
- Excessive physical activity
Neurological Weakness
Caused by issues in the nervous system, affecting the brain, spinal cord, or nerves. Examples include:
- Stroke
- Multiple sclerosis (MS)
- Parkinson’s disease
- Peripheral neuropathy (nerve damage)
Psychological or Emotional Weakness
Mental or emotional distress can lead to feelings of weakness or exhaustion, even if there is no physical cause. Examples include:
- Depression and anxiety
- Stress and burnout
- Post-traumatic stress disorder (PTSD)
Functional Weakness
This occurs when the nervous system does not properly control muscle function despite no structural damage. It is often linked to:
- Functional neurological disorders (FND)
- Psychological stress
Each type of weakness requires different treatments, so identifying the underlying cause is essential for proper management and recovery.
Weakness Symptoms
The symptoms of weakness vary depending on its cause and severity. Common symptoms include:
Physical Symptoms
- Loss of Strength: Difficulty in lifting objects, standing, or walking.
- Muscle Fatigue: Muscles tire easily, even with minimal exertion.
- Shakiness or Trembling: Involuntary muscle movements or trembling hands.
- Slow Movements: Reduced ability to perform normal activities quickly.
- Muscle Pain or Cramping: Discomfort or spasms in weak muscles.
- Balance Problems: Difficulty maintaining stability, leading to falls.
Generalized Symptoms
- Extreme Fatigue: Persistent tiredness, even after rest.
- Dizziness or Lightheadedness: Feeling faint or unsteady.
- Shortness of Breath: Difficulty breathing, especially with exertion.
- Pale or Yellowish Skin: Often seen in anemia or nutritional deficiencies.
Neurological Symptoms
- Numbness or Tingling: A “pins and needles” sensation in the affected area.
- Coordination Problems: Difficulty in walking or controlling body movements.
- Slurred Speech or Vision Changes: May indicate neurological conditions like stroke.
Psychological Symptoms
