Warning Signs of Aneurysm in Men: Symptoms You Should Know

An aneurysm can develop quietly for years without causing noticeable symptoms. In some cases, however, an aneurysm can suddenly rupture or cause other serious complications. Knowing the possible warning signs of an aneurysm in men can help people recognize symptoms that require urgent medical attention.

An aneurysm occurs when part of a blood vessel, usually an artery, becomes weakened and bulges outward. Aneurysms can develop in different parts of the body, but they are commonly associated with the aorta, the body’s largest artery, and with blood vessels in the brain.

Not every aneurysm causes symptoms, and many are discovered unexpectedly during medical imaging performed for another reason. When symptoms do occur, they depend largely on the aneurysm’s location, size, and whether it is pressing on nearby structures.

Importantly, an aneurysm can become a medical emergency if it ruptures. Sudden, severe pain or neurological symptoms should never be ignored.

What Is an Aneurysm?

An aneurysm develops when a weakened area in the wall of an artery begins to expand or bulge.

Think of an artery as a flexible tube carrying blood throughout the body. If part of the vessel wall becomes weaker, the pressure of blood moving through the artery can cause that section to widen.

Some aneurysms remain stable for years. Others gradually increase in size and may eventually rupture or cause problems.

Aneurysms can occur in several locations, including:

• The abdominal aorta
• The chest portion of the aorta
• Brain arteries
• Leg arteries
• Other blood vessels

The symptoms can be very different depending on where the aneurysm develops.

1. Sudden, Severe Headache

A sudden and extremely severe headache can be a warning sign of a ruptured brain aneurysm.

People sometimes describe this type of headache as unusually intense or unlike headaches they have experienced before.

A ruptured aneurysm in the brain can cause bleeding around the brain, which is a life-threatening emergency.

A sudden severe headache may occur with:

• Nausea or vomiting
• Neck stiffness
• Sensitivity to light
• Confusion
• Loss of consciousness
• Seizures
• Vision problems

If someone develops a sudden, severe headache that reaches maximum intensity rapidly, seek emergency medical attention immediately.

2. Sudden Loss of Consciousness

Fainting or losing consciousness can occur for many reasons, but sudden loss of consciousness can be particularly concerning when it occurs alongside severe pain or neurological symptoms.

A ruptured brain aneurysm can cause bleeding and increased pressure inside the skull, potentially resulting in unconsciousness.

A person who suddenly collapses, becomes unresponsive, or cannot be awakened normally needs emergency medical assessment.

3. Sudden Vision Changes

Changes in vision can sometimes occur when a brain aneurysm presses on nearby nerves or other structures.

Possible symptoms include blurred vision, double vision, loss of vision, or difficulty seeing normally.

Sudden vision changes can also have many other causes, including stroke and eye emergencies.

If vision changes occur suddenly, especially together with weakness, confusion, difficulty speaking, or a severe headache, emergency care is necessary.

4. Severe Abdominal Pain

An abdominal aortic aneurysm can sometimes cause pain in the abdomen.

The discomfort may be persistent, deep, or unusual. Some people may also notice a pulsing sensation in the abdomen.

A ruptured abdominal aortic aneurysm can cause sudden, severe abdominal pain and rapidly become life-threatening.

Severe abdominal pain accompanied by dizziness, weakness, fainting, or cold sweating requires immediate emergency attention.

5. Back Pain

Back pain can sometimes occur with an abdominal or thoracic aortic aneurysm.

Aneurysms may cause discomfort by pressing against nearby tissues or structures.

However, back pain is extremely common and usually has causes unrelated to aneurysms, including muscle strain and spinal conditions.

The concern is greater when sudden or severe back pain occurs together with abdominal or chest pain, fainting, weakness, or other unusual symptoms.

6. Chest Pain

An aneurysm involving the chest portion of the aorta may cause chest pain or discomfort.

The pain may be felt in the chest, upper back, or between the shoulder blades.

Sudden, severe chest or upper-back pain should always be taken seriously because several life-threatening conditions can produce similar symptoms.

Do not try to determine at home whether severe chest pain is caused by an aneurysm, heart attack, or another condition. Seek emergency medical care.

7. A Pulsating Feeling in the Abdomen

Some people with an abdominal aortic aneurysm may notice a pulsing sensation in the abdomen.

This can sometimes feel like a heartbeat in the stomach area.

However, feeling a pulse in the abdomen does not automatically mean an aneurysm is present. Thin individuals may naturally be able to feel the abdominal pulse.

If you notice a new or unusual pulsating mass or sensation, particularly if it is accompanied by abdominal or back pain, discuss it with a healthcare professional.

8. Difficulty Speaking

A brain aneurysm can sometimes cause neurological symptoms, particularly if it presses against nearby brain structures or contributes to bleeding.

Difficulty speaking or understanding speech can be a warning sign of a serious neurological problem.

Sudden trouble speaking should be treated as an emergency, especially if accompanied by facial drooping, weakness, confusion, or difficulty walking.

9. Weakness or Numbness

Sudden weakness or numbness affecting the face, arm, or leg can indicate a serious problem involving the brain.

Although these symptoms can have many causes, they may occur with bleeding caused by a ruptured aneurysm or other neurological emergencies.

Sudden one-sided weakness or numbness requires immediate medical attention.

10. Trouble Walking or Maintaining Balance

A brain aneurysm or bleeding inside the skull can affect areas of the brain responsible for movement and coordination.

A person may suddenly become unsteady, have difficulty walking, or lose coordination.

Because these symptoms can also indicate a stroke or other emergency, sudden difficulty walking should never be ignored.

11. Neck Pain or Stiffness

Neck stiffness or pain can accompany bleeding around the brain after an aneurysm ruptures.

This may occur alongside a severe headache, nausea, vomiting, sensitivity to light, or changes in consciousness.

A stiff neck by itself is commonly caused by muscle tension or other minor problems. But sudden neck stiffness combined with an unusually severe headache requires emergency assessment.

12. Nausea and Vomiting

Nausea and vomiting may occur when a brain aneurysm ruptures and bleeding affects the brain.

They can also occur with severe abdominal problems.

Because nausea and vomiting are extremely common, these symptoms alone are not enough to identify an aneurysm.

They become more concerning when they appear suddenly alongside severe headache, neurological changes, abdominal pain, or loss of consciousness.

13. Shortness of Breath

A thoracic aortic aneurysm can sometimes cause breathing difficulties if it becomes large enough to affect nearby structures.

Shortness of breath can also have many other causes, including asthma, heart conditions, infections, and lung problems.

Sudden or severe difficulty breathing is an emergency, particularly when accompanied by chest pain, fainting, confusion, or weakness.

14. Hoarseness or Difficulty Swallowing

An aneurysm in the chest can potentially press against nearby structures, including nerves or the esophagus.

This may contribute to symptoms such as hoarseness, coughing, or difficulty swallowing.

These symptoms have many possible causes and are not specific to aneurysms.

Persistent or unexplained symptoms should be discussed with a healthcare professional.

15. Unusual Fatigue or Weakness

A person experiencing internal bleeding from a ruptured aneurysm may suddenly feel extremely weak, dizzy, or faint.

Severe blood loss can cause the body’s blood pressure to fall, potentially leading to shock.

This is very different from ordinary tiredness after a busy day.

Sudden weakness combined with severe abdominal, chest, or back pain is a medical emergency.

Why Aneurysms Can Be Dangerous

The danger of an aneurysm depends on its size, location, growth rate, and other individual factors.

Some aneurysms remain stable and never rupture. Others can enlarge over time.

If an aneurysm ruptures, internal bleeding can occur. A ruptured brain aneurysm can cause bleeding around the brain, while a ruptured aortic aneurysm can result in severe internal bleeding.

Both situations can be life-threatening.

This is why knowing emergency symptoms is so important.

Aneurysm Risk Factors in Men

Men can develop aneurysms for many of the same reasons as women, but some types of aneurysms, particularly abdominal aortic aneurysms, are more common in men.

Risk can increase with factors such as:

• Older age
• Smoking or previous tobacco use
• High blood pressure
• Atherosclerosis
• Family history of aneurysm
• Certain inherited conditions
• Previous blood-vessel problems

Not everyone with risk factors will develop an aneurysm, and people without obvious risk factors can still develop one.

Can an Aneurysm Be Prevented?

There is no guaranteed way to prevent every aneurysm, but managing cardiovascular risk factors can support overall blood-vessel health.

Important steps include avoiding tobacco, controlling blood pressure, staying physically active, maintaining a healthy weight, and following a balanced diet.

If you have high cholesterol, diabetes, high blood pressure, or another cardiovascular risk factor, work with a healthcare professional to manage it appropriately.

People with a strong family history of aneurysms should also discuss their risk with a doctor.

When Is an Aneurysm an Emergency?

Certain symptoms require immediate emergency care.

Call your local emergency service if someone develops:

• A sudden, extremely severe headache
• Sudden loss of consciousness
• Severe or sudden chest pain
• Severe abdominal or back pain
• Sudden weakness or numbness
• Sudden difficulty speaking
• Sudden vision loss or major vision changes
• Severe dizziness or collapse
• Signs of shock, such as extreme weakness, cold or clammy skin, or confusion

Do not drive yourself if you are experiencing potentially life-threatening symptoms. Emergency medical services can begin assessment and treatment while transporting you to appropriate care.

How Are Aneurysms Found?

Some aneurysms are discovered accidentally during imaging for another health concern.

Depending on the suspected location, doctors may use imaging techniques to examine blood vessels and determine whether an aneurysm is present.

The appropriate test depends on symptoms, risk factors, medical history, and the suspected location of the aneurysm.

A healthcare professional may recommend monitoring for some smaller aneurysms rather than immediate treatment. Larger or high-risk aneurysms may require more active management.

Final Thoughts

Aneurysms can develop without obvious warning signs, which makes awareness particularly important.

Potential symptoms vary depending on the location of the aneurysm. A brain aneurysm may be associated with sudden severe headache, vision changes, neck stiffness, weakness, difficulty speaking, or loss of consciousness. An aortic aneurysm may cause chest, abdominal, or back pain, while a rupture can cause sudden severe pain, weakness, dizziness, and collapse.

Most of these symptoms have many possible causes and do not automatically mean that an aneurysm is present.

The most important message is to recognize symptoms that are sudden, severe, or dramatically different from anything you have experienced before. In particular, sudden severe headache, chest pain, abdominal pain, back pain, fainting, or neurological changes should be treated as potential medical emergencies.

When it comes to aneurysms, prompt medical evaluation can be critical. If you have concerns about your personal risk, especially because of age, smoking history, high blood pressure, or family history, discuss them with a qualified healthcare professional.
