Best Answer

1. Infection of micro-organisms like virus & bacteria.

2. Hormonal imbalance in the body

3. Anatomical malformations

We can also underline these causes as Pathological, Physiological and anatomical.

I might classify them as: 1. infection, 2. psychosomatic, 3. poisons (some overlap with infections), 4. hormonal imbalances, etc. I am less likely to consider anatomical malformations as a disease. Consider: pathological, physiological, psychological.
