5 reasons you should not ignore frequent nosebleeds

A nosebleed can happen suddenly, whether a person is at home, in the office, in school or outdoors. In many cases, the bleeding stops within a short time and does not indicate a serious health problem. However, when nosebleeds happen repeatedly, they should not be ignored.

The nose contains many small blood vessels close to the surface of its lining. These vessels can break easily when the inside of the nose becomes dry, irritated or injured. Although occasional nosebleeds are common, repeated episodes may require medical assessment to identify the cause.

Some people experience frequent nosebleeds during hot weather, while others notice them after blowing their nose, having a cold or dealing with allergies. In other cases, medicines or conditions affecting blood clotting may be responsible.

In this article, Tribune Online highlights five reasons you should not ignore frequent nosebleeds.

Repeated nosebleeds may indicate persistent irritation inside the nose

One common reason for repeated nosebleeds is irritation of the delicate lining inside the nose.

The nasal lining contains small blood vessels that can break when the tissue becomes dry or damaged. Dry weather, air conditioning, dust and other environmental conditions may contribute to irritation, particularly when the nasal lining is already sensitive.

Picking the nose, inserting objects into the nostrils or blowing the nose too forcefully can also damage these vessels. Once a vessel has broken, a small amount of bleeding may occur. If the area is disturbed again before it heals, another episode may follow. This can create a cycle in which the same area repeatedly bleeds because it has not had enough time to recover.

People who experience this problem may benefit from avoiding nose-picking, blowing their nose gently and keeping the nasal lining from becoming excessively dry. A saline nasal spray may help some people, while a pharmacist or healthcare professional can advise on suitable products for persistent dryness.

It is also important to avoid inserting tissue, cotton wool or other objects deeply into the nostrils in an attempt to stop bleeding, as removing them can disturb the affected area.

However, repeated bleeding should not automatically be attributed to dry weather or irritation. If nosebleeds continue despite simple preventive measures, a healthcare professional should examine the nose to determine whether another cause is responsible.

It can be associated with allergies or persistent nasal inflammation

Allergies  and infections affecting the nose can make its lining inflamed and more vulnerable to bleeding. People with allergic rhinitis may experience sneezing, a runny or blocked nose, itching and watery eyes. These symptoms can encourage frequent rubbing, wiping and blowing of the nose, increasing the risk of damaging the delicate blood vessels.

A common cold and other upper respiratory infections may also cause nasal inflammation. Repeated sneezing and forceful nose-blowing during an illness can worsen irritation and trigger bleeding. The problem may become more noticeable when a person has recurring allergies or is frequently exposed to substances that trigger symptoms, such as dust or pollen.

Some nasal medicines can also contribute to bleeding, particularly when decongestant sprays  are used more frequently or for longer than recommended. Certain sprays may irritate the nasal lining, while incorrect application can direct medicine towards the sensitive middle wall of the nose. People experiencing frequent nosebleeds alongside persistent sneezing, nasal itching or congestion should discuss these symptoms with a healthcare professional.

Managing the underlying allergy or inflammation may help reduce irritation, but treatment should be appropriate for the person’s symptoms and medical history.

Repeated nosebleeds accompanied by persistent blockage on one side of the nose, unusual discharge or other unexplained symptoms also deserve assessment rather than repeated self-treatment.

Frequent nosebleeds may be linked to high blood pressure

High blood pressure  is often discussed in relation to nosebleeds, but the relationship requires careful explanation. Having a nosebleed does not prove that a person has high blood pressure. Nosebleeds have many possible causes, including local irritation, dryness, allergies and minor injuries.

However, people with high blood pressure may experience bleeding that is more difficult to control. High blood pressure is also more common among people who experience nosebleeds, particularly older adults, although this does not establish that it directly caused an individual episode.

A person who experiences repeated nosebleeds, especially alongside other cardiovascular risk factors, may benefit from having their blood pressure checked.

High blood pressure often causes no obvious symptoms. A person can therefore have the condition without experiencing headaches, dizziness or nosebleeds.

This is why blood pressure should be measured rather than estimated from symptoms alone. If a person is found to have high blood pressure, a healthcare professional can recommend appropriate measures, which may include lifestyle changes and medicines depending on the readings and individual circumstances. 

It is important not to start blood pressure medicines simply because of a nosebleed. The cause of the bleeding and the person’s blood pressure need to be assessed separately.

They may signal a blood-clotting problem or the effects of certain medicines

Blood normally forms clots that help stop bleeding after a blood vessel is damaged. When this process is affected, bleeding may continue longer than expected or occur more easily.

Some inherited or acquired conditions can interfere with normal blood clotting. For example, haemophilia and von Willebrand disease can cause abnormal bleeding, although their symptoms and severity vary.

Repeated nosebleeds may be one feature of a bleeding disorder, particularly when they occur alongside easy bruising, prolonged bleeding from minor cuts, unusually heavy menstrual periods or a family history of bleeding problems.

Certain medicines can also make bleeding more likely or harder to stop. These include anticoagulants, which reduce the blood’s ability to clot, and some antiplatelet medicines, which affect how platelets work. Examples include warfarin and medicines such as aspirin or clopidogrel. Whether a medicine contributes to an individual’s nosebleeds depends on the medicine, dose, other health conditions and circumstances.

People taking these medicines should not stop or change their doses without medical advice. Suddenly stopping a prescribed blood-thinning medicine can expose a person to serious risks, depending on why it was prescribed.

Instead, repeated nosebleeds should be reported to the prescribing healthcare professional. 

They can assess whether the medicine, an underlying condition or another cause is responsible. If frequent nosebleeds occur alongside unusual bruising or bleeding from other parts of the body, medical assessment is particularly important.

Repeated or heavy bleeding can lead to anaemia

Another reason not to ignore frequent nosebleeds is that repeated blood loss can contribute to anaemia. Anemia occurs when the body does not have enough healthy red blood cells or haemoglobin to carry oxygen effectively to its tissues. Iron deficiency is one possible cause.

A single minor nosebleed is unlikely to cause anemia in an otherwise healthy person. However, frequent or heavy bleeding over time can contribute to significant blood loss.

Possible symptoms of anemia include persistent tiredness, weakness, pale skin, shortness of breath, dizziness and noticeable heartbeats. These symptoms can also occur with other conditions, so they do not establish the diagnosis on their own.

If nosebleeds are accompanied by these symptoms, a healthcare professional may recommend blood tests to check for anaemia and investigate the cause of the bleeding.

It is important to identify why the nose is bleeding rather than simply treating possible iron deficiency. 

Taking iron supplements without confirming a deficiency may be unnecessary and can cause side effects. People who repeatedly lose blood should therefore seek assessment to determine whether they need treatment for the bleeding, anemia or both.
