 Do you feel like you're always tired?

 Diseases whose main cause is fatigue.

 When your immune system is attacked by any disease, it needs energy to fight it. So it's perhaps no surprise that fatigue is one of the symptoms you can name. Fatigue may be the most common symptom that people often mention, and it itself may not tell you what's causing it.

Some people may experience runny nose, itching and difficulty breathing due to allergies. When people come into contact with such an allergen, the body releases the chemical histamine to fight it. It causes symptoms of an allergic reaction, which may include sudden fatigue.
