Nasal congestion and trouble breathing are common symptoms of a deviated septum, explains WebMD. Other symptoms include facial pain, postnasal drip, nosebleeds and loud snoring during sleep. In severe cases, a deviated septum may cause sleep apnea.
A minor deviated septum may have few or no symptoms, according to Healthline. Other patients experience mild to severe symptoms, including frequent sinus infections, headaches and difficulty breathing, explains WebMD.
Some patients who suffer from a deviated septum may have an obstruction on one or both nostrils, reports Mayo Clinic. This makes it more difficult to breathe through the nostrils. The situation is more noticeable when the patient has allergies or a cold, and the nasal passage may swell.
Nosebleeds are a common symptom of a deviated septum since the condition causes the nasal septum to become dry, states Mayo Clinic. Some patients snore loudly and experience sleep disruptions. Infants and young children are more likely to breathe loudly when they sleep.
Patients with a deviated septum are more aware of their nasal cycle, and some may experience facial pain, explains Mayo Clinic. In case the deviated septum narrows one nostril, the patient may have a preference for sleeping on one side. This makes it easier to breathe through the nose at night. Other patients have to breathe through the mouth due to nasal obstruction, and this causes dry mouth, notes Healthline.
