What causes weakness in the legs when walking?
Disease description:
I have stayed at home for a long time without going outside or getting sunlight. When I went out again, I felt weak in my legs and had difficulty walking after just one or two steps. Why is this happening?

Common possible causes of leg weakness during walking:
1. Physiological factors: Excessive activity or fatigue from the previous days can lead to lactic acid buildup, causing tiredness and weakness during walking the following day.
2. Neurological diseases: Conditions such as multiple sclerosis, spinal cord injury, and peripheral neuropathy can affect nerve conduction, resulting in muscle weakness.
3. Muscle diseases: Myasthenia gravis, muscular dystrophy, chronic fatigue syndrome, and similar conditions directly affect the muscles, causing a decrease in muscle strength.
4. Bone and joint problems: Conditions such as osteoporosis, arthritis, and synovitis may restrict movement and cause pain, indirectly affecting walking ability.
5. Cardiovascular diseases: Heart failure, arteriosclerosis obliterans, and other conditions causing poor circulation can deprive muscles of adequate oxygen and nutrients, leading to weakness.
6. Metabolic diseases: Conditions such as diabetes and thyroid dysfunction may affect nerve or muscle function.
7. Malnutrition: A long-term deficiency in nutrients such as protein, vitamin D, and calcium can also lead to muscle weakness.
