What causes nosebleeds while swimming

Many people like swimming very much, especially those who are losing weight. They like to swim frequently. Many people will have nosebleeds when swimming. This situation is probably caused by the discomfort caused by the pressure of the water to the human body, resulting in nosebleeds. Therefore, you must make corresponding preparations before swimming, and do not make large movements during swimming.

What causes nosebleeds while swimming?

There is no direct relationship between nosebleed and swimming. Nosebleed is related to the pressure of water and may be caused by the inability to adapt to this pressure. However, it cannot be ruled out that the nasal cavity is impacted when entering the water, or that the nasal cavity is under excessive pressure due to diving too deep.

Causes of Nosebleeds

1. General treatment

First, comfort and calm the nervous and frightened patients and their families to prevent the patients' blood pressure from rising due to mental factors, which may aggravate the bleeding. Measure blood pressure and pulse in time, and give fluids when necessary to maintain stable vital signs. If the patient is in shock, first aid should be given to treat the shock. When inquiring about the medical history, the following situations should be inquired: which side of the nose is bleeding or which side of the nose bleeds first, the speed and amount of bleeding, whether there has been recurrent nose bleeding in the past, whether there is a cause for this bleeding, and whether there are other accompanying symptoms.

2. Find the bleeding point

Depending on the specific situation, local nasal and systemic examinations are performed. When examining the nasal cavity, clear the blood clots in the nasal cavity, use 1% ephedrine and dicaine to fully shrink and anesthetize the nasal mucosa, and find the bleeding site as much as possible to stop the bleeding accurately. If conditions permit, it is best to find the bleeding point under nasal endoscopy and implement hemostatic treatment.

3. Methods of stopping bleeding in the nasal cavity

Choose different hemostasis methods according to the severity, location, amount and cause of bleeding.

(1) Finger pressure method: Patients can pinch both nostrils with their fingers or press the bleeding nostril against the nasal septum for 10 to 15 minutes. They can also press the upper lip horizontally with their fingers and apply cold compresses to the forehead and back of the neck at the same time. This method is suitable for patients with small amounts of bleeding and bleeding in the front of the nasal cavity. Patients can use this method when nosebleeds occur at home.

(2) Local hemostatic drugs are suitable for milder anterior nasal bleeding. This method is simple and easy and causes less pain to the patient. For bleeding areas, you can use cotton pads soaked in 1% ephedrine, 1‰ epinephrine, 3% hydrogen peroxide solution or thrombin, and tightly plug the nasal cavity for several minutes to several hours to achieve the purpose of hemostasis.

(3) Commonly used cautery methods include chemical cautery and physical cautery (including electric cautery, laser cautery and microwave cautery). For bleeding located in the anterior and inferior part of the nasal septum, the bleeding site can be clearly seen after the nasal mucosa has been fully contracted and anesthetized. You can use a cotton ball dipped in a small amount of 30-50% silver nitrate or 30% trichloroacetic acid to cauterize the bleeding point, and press on the bleeding point for a while until a white film is formed locally.
