How to manage for foul odour from nose with bad taste? – Dr. Satish Babu K

A foul odour or bad taste in the mouth along with the dryness commonly happens when the person breathes through the mouth predominantly especially in sleep. That means, person is already having a bit of nasal block. Day times this nasal block may not be very significant, but in the night when there is a lot more of oxygen demand, then the automatically mouth opens up allowing much more air to come in, and oxygen to be delivered to the body. This movement in the area of mouth and throat region dries up the mouth and throat very easily. Dryness leads to the nerve endings being disturbed, where they don’t function as well as well a well moist normal skin. This leads to a bit of bad taste, some burning sensation, all these symptoms, scratchy sensation in throat leading to hacking or cough. A foul smell inside the nose along with these symptoms it needs investigation, the origin of the foul smell needs to be diagnosed most likely occurring due to sinus block, pus formation somewhere.
If you treat the cause of the foul smell, nose also opens up, the person goes back to proper nose breathing regularly, and all these dryness and bad taste will disappear.
