Weakness is a symptom used to describe a number of different conditions, including: lack of muscle strength, malaise, dizziness or fatigue. The causes are many and can be divided into conditions that have true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy. It occurs in neuromuscular junction disorders, such as myasthenia gravis.
Fatigue (also called exhaustion, lethargy, languidness, languor, lassitude, and listlessness) is a state of awareness varying from a general state of lethargy to a specific work-induced burning sensation within one’s muscles. Physical fatigue is the inability to continue functioning at the level of one’s normal abilities. Mental fatigue, on the other hand, rather manifests in somnolence (sleepiness).
Fatigue is considered a symptom because it is reported by the patient instead of being observed by others.

Fatigue after Eating
Feeling of fatigue after eating is very common. After we eat food, especially a heavy lunch or dinner, the blood supply from our brain and limbs decreases and the blood supply in our stomach and intestine increases to facilitate digestions. This change in blood flow and oxygenation causes a feeling of dullness, drowsiness and fatigue after eating.
