HCM CitySince Tet, each month Tam Anh General Hospital receives nearly 100 cases of nosebleeds, some of whom are hospitalized for many days of treatment.
On March 5, M.D. Nguyen Trung Nguyen, Ear, Nose and Throat Center, Tam Anh General Hospital, Ho Chi Minh City, said the above information, adding that the weather in Ho Chi Minh City is hot, with temperatures above 3 degrees Celsius. prolonged, causing the number of patients examined for nosebleeds (nosebleeds) to increase by 37-50% compared to before.
Doctor Nguyen explains that the sun makes the nasal mucosa dry and susceptible to allergies. These capillaries dilate too much and burst, causing bleeding. Many people have the habit of picking their nose and blowing their nose vigorously, increasing the risk of nosebleeds.
People are at risk of nosebleeds in hot weather due to thin nasal mucosa, such as children, people with nasal polyps (benign tumors in the nasal cavity), and rhinosinusitis. People who work in dusty environments or smoke because cigarette smoke causes heat to dry and congest the nasal mucosal surface. People who drink a lot of alcohol, the alcohol in beer dilates the arteries... are also prone to nosebleeds in the hot season.

According to Dr. Nguyen, people with a history of high blood pressure are at risk of frequent and frequent nosebleeds in the dry season. Hot temperatures make the heart beat faster or the body's sudden temperature change between outdoors and in an air-conditioned room causes blood vessels to instantly constrict and blood pressure to increase. At this time, the pressure on the blood vessel walls also increases, leading to rupture and nosebleeds. Elderly patients with both high blood pressure and arteriosclerosis may have more nosebleeds.
Like Mr. Hung, 75 years old, was transferred to Tam Anh General Hospital in Ho Chi Minh City for emergency treatment due to nosebleeds. Mr. Hung has underlying diseases such as diabetes and hypertension. The doctor placed merocel (a soft material that expands when exposed to liquid solution) into his nasal cavity to stop the bleeding and bring his blood pressure to a stable level.
As for Mr. Nam, 33 years old, his nose bleeds continuously, recurring for nearly half a month. The doctor diagnosed him with bleeding from the inferior turbinate vascular bud. He was treated to cauterize the bleeding point with silver nitrate, but it only covered the superficial surface and did not completely resolve it. After endoscopy, the patient was treated by cauterizing the lower nasal turbinate blood vessel buds with a bipolar electric knife and was discharged the same day.

Another case is Ms. Hoa, 27 years old, who also had recurrent nosebleeds many times and did not get better after taking medicine. Doctors at Tam Anh General Hospital in Ho Chi Minh City diagnosed her with a bleeding point in the nasal septum and treated it by cauterizing the bleeding point with silver nitrate. After three days of follow-up examination, Ms. Hoa no longer had nosebleeds.
Nosebleeds are due to many causes, such as abnormalities in the vascular structure on the nasal mucosa, deviated nasal septum, medical complications, sinus tumors, and rhinosinusitis.
Patients with nosebleeds recur many times during the hot season, mainly due to inadequate or incorrect treatment.
Doctor Nguyen added that when nosebleeds, the patient should sit up, lean slightly forward, use hands to squeeze directly on the nostrils, the location causing the bleeding and hold for 5-10 minutes, can repeat. 2-3 times if the bleeding has not stopped. You can place some ice on the bridge of your nose to constrict blood vessels and reduce blood flow. If you continuously squeeze your nose but the bleeding still does not stop, you should go to the hospital for first aid.
If you have nosebleeds multiple times in two weeks, you should see a doctor for timely examination and treatment. Continuous nosebleeds can be a symptom of a number of underlying diseases such as nasopharyngeal fibroids, nasopharyngeal cancer...
Depending on the cause, doctors choose different nosebleed treatment methods such as internal medicine, cauterizing the bleeding point using silver nitrate, and cauterizing with a bipolar electric knife. Nosebleeds due to tumors in the sinus area require endoscopic surgical intervention for complete treatment.
To prevent nosebleeds in hot weather, Dr. Nguyen recommends cooling down the air in the house by using fans, air conditioners, and well-ventilated windows. Cool your body by drinking enough water and eating lots of green vegetables and fruits. Limit eating a lot of spicy and hot foods, supplement vitamin C and K through foods such as oranges, kiwi, spinach, and bananas.
Regularly clean your nose with physiological saline to reduce dryness of the nasal mucosa. People with high blood pressure should check their blood pressure regularly, in a well-ventilated place, and limit walking in hot weather.
