I'm sorry to hear you're experiencing regular nasal blockage and throat irritation along with mouth breathing that leads to bloating and shortness of breath. These symptoms can be quite uncomfortable.

Nasal blockage often causes people to breathe through their mouth, which can dry out the throat and cause irritation. Mouth breathing can also lead to swallowing more air, which might cause bloating and sometimes a feeling of shortness of breath. Common causes of nasal blockage include allergic rhinitis (allergies), sinus infections, or structural issues in the nose.

A medication like a corticosteroid nasal spray, which reduces inflammation in the nasal passages, may help relieve symptoms if allergies or inflammation are involved. However, it’s important to use such treatments under medical supervision.

Given your symptoms, I recommend consulting an ear, nose, and throat (ENT) specialist. They can evaluate your nasal passages, identify any underlying causes, and suggest appropriate treatment to improve your breathing and reduce throat irritation.

If your shortness of breath worsens or you experience severe discomfort, seek urgent medical attention promptly.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
