In my openion this is due to chronic sinusitis or digestive imbalance Sinusitis tonsillitis   acid reflex(digestive problem)may cause bad breath (Other cause are dental problem)

visit hospitals and detailed checkup

In my opinion bad breath could be caused due to inadequate hygiene maintenance.IBS could also be a factor which would increase the foul odour.Acculmulation of plaque and calculus deposits a the usual causes though of bad breath.

You sholud visit a dentist nearby and get a thorough cleaning and polishing done. Mean whipe you could also start with a mouthwash like Hexidene-EP for prolonged use to reduce bad breath.
