Patients with runny nose and tears may be caused by crying, cold and allergic rhinitis.
1. Crying: when people cry, sympathetic and parasympathetic nerves are excited, which can make the lacrimal glands secrete a large amount of tears, and a large amount of tears flow into the nasolacrimal duct, which can produce certain stimulation to the nasal mucosa, thus leading to the patient’s appearance of running tears, runny nose and other manifestations.
2. Colds: When you have a cold, the nasal mucosa secretion increases, which can lead to symptoms such as runny nose and nasal congestion. When the swollen nasal mucosa blocks the nasolacrimal duct, the tears can not flow into the nasolacrimal duct, and there will also be symptoms of tearing.
3. Allergic rhinitis: Allergic rhinitis can be triggered by contact with pollen, hair and other allergens in desensitized patients, and the nasal mucosa will be swollen, congested, and secretion will be enhanced under the stimulation of histamine, which will lead to runny nose, tearing and other uncomfortable symptoms in patients.
It is recommended that patients with obvious symptoms such as runny nose and tearing should consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
