The reasons for nose bleeding when angry are as follows: 1, emotional changes when angry, resulting in abnormally high blood pressure, which can easily cause nose bleeding symptoms; 2, the patient’s nasal mucosa is already congested, dry, etc., which can easily cause the mucosa to rupture when angry, resulting in bleeding; 3, some patients may also repeatedly dig their nostrils, nose rubbing actions, increasing the chances of nose bleeding. If patients repeatedly have symptoms of nosebleeds, they need to go to the hospital for further detailed examination of the nose to find the specific site and cause of nosebleeds, and take targeted treatment and improvement measures.
