Random nose bleeds are very common and anyone can go through this experience at least once in their life. These are not supposed to cause any alarm, they normally have harmless causes. It would be problematic if you start getting frequent nosebleeds. This will urgently need the doctor’s attention.
According to Joseph Parambil, M.D, a Pulmonary Medicine Specialist at Cleveland Clinic, people with hereditary hemorrhagic telangiectasia (HHT) have abnormal blood vessels. These abnormal blood vessels allow frequent flow of blood out of the body through the nose. This is a very rare condition and it is very hard to detect in its early stages. However, persistent problems should not be neglected or rejected as normal. Seeing a doctor could prove helpful in identifying any underlying problems.
Besides the rarity of this condition, common nosebleed causes include nose injury, nose inflammation or distortions. Sometimes having these conditions can be frightening as something would seem wrong, but it is very common.
To allay your anxiety, here are 10 weird causes for a sudden nosebleed.
Cold weather is the main culprit that triggers nosebleeds. The potential for the problem becomes worse during dry weather. In the US, the period between December and March can be referred to as the ‘nosebleed period’. This is because the air would be cold and dry during this time of the year.
When it is cold outside, most people turn on their heating systems, this makes it even worse for the nose. The change in air quality is the main culprit. Professor Erich Voigt, M.D, who is a clinical associate in the Department of Otolaryngology, stated that the cold weather and home heating systems promote the development of cracks in nose membranes.
When these membrane cracks are irritated, nosebleeds starts. According to the professor, the blood vessels in the nose help to keep the surroundings moist and filter the air inhaled. Cold and dry weather irritate the blood vessels thereby making them bleed.
