What Causes a Bulbous Nose?

The direct cause of rhinophyma, which is a rare disorder that gives the nose a bulb-like shape, is unknown. Although once this condition was believed to be linked to excessive alcohol use, it may perhaps be a very severe type of rosacea, states the National Institute of Health.

Other symptoms associated with rhinophyma are an increase in nose oil glands, skin thickening, reddish nose and enlarged pores. The condition seems to affect more men than women.

Rhinophyma progresses slowly over time and can occur in people with severe rosacea, reports Healthline. Rosacea is a skin condition that causes the face to appear flushed and pustules may also form. Certain medications and surgery are possible treatment options for rhinophyma.
