Polyphagia is a medical condition where the person feels excessively hungry or has suddenly increased appetite.
Excessive hunger is considered normal if it is followed by some strenuous exercises. But if it persists for a longer period of time and is not triggered by any external activity, it can be an indication of a serious condition.
In most of the cases, polyphagia is a sign of diabetes. The other reasons for polyphagia can be stress, anxiety, improper sleeping habits, eating disorders, thyroid dysfunction and premenstrual syndrome.
A person can prevent polyphagia by eating healthy fibre-rich food, sleeping for 8 hours and meditating. The treatment of polyphagia depends upon the underlying condition.
