What Happens If You Swallow A Needle? A Detailed Look

Swallowing a needle can be an alarming experience. The sharp, pointed object seems like it could easily damage your insides. You may wonder where the needle will end up and if it can harm you. Let’s take an in-depth look at what happens when you swallow a needle.

If you’re short on time, here’s the quick answer: Swallowing a needle is generally not life threatening. The needle typically passes through the digestive tract and is excreted in the feces within 1 to 2 weeks without causing any damage or requiring intervention.

However, there are some risks such as perforation or infection, so it’s important to monitor symptoms and see a doctor if any complications arise.

What Happens Immediately After Swallowing a Needle

Swallowing a needle can be a frightening experience, but understanding what happens next can help alleviate some of the anxiety. Here is a detailed look at what happens immediately after swallowing a needle:

The needle travels down the esophagus into the stomach

Once the needle is swallowed, it enters the esophagus, which is the muscular tube connecting the mouth to the stomach. The esophagus is designed to transport food and liquids from the mouth to the stomach, and it does the same for foreign objects, such as a needle.

The needle will continue its journey down into the stomach, where further processes will take place.

Digestive juices and muscles help move the needle through the GI tract

Once in the stomach, the needle is exposed to digestive juices. These juices, made up of hydrochloric acid and enzymes, aid in the breakdown of food. The needle itself is not digestible, so it will not be broken down by these juices.

However, the muscles of the stomach and the rest of the gastrointestinal (GI) tract will continue to move in a coordinated manner, helping to push the needle along the digestive system.

It is important to note that the movement of the needle through the GI tract can vary depending on a variety of factors, including the size and shape of the needle, as well as individual differences in digestive function.

In some cases, the needle may pass through the GI tract without causing any further issues.

The needle may cause some discomfort or irritation

As the needle travels through the GI tract, it may cause some discomfort or irritation. This can manifest as mild pain or a feeling of pressure in the chest or abdomen. It is also possible for the needle to cause small scratches or tears in the lining of the esophagus, stomach, or intestines.

However, the body has a remarkable ability to heal itself, and these minor injuries typically resolve without any long-term consequences.

If you or someone you know has swallowed a needle, it is important to seek medical attention immediately. A healthcare professional will be able to assess the situation and determine the best course of action. In some cases, an endoscopy may be performed to safely remove the needle.

Risks and Potential Complications

Swallowing a needle can have serious risks and potential complications. Here are some of the most common ones:

Perforation or puncture of the digestive tract

One of the main concerns when swallowing a needle is the possibility of it causing perforation or puncture of the digestive tract. The sharp end of the needle can cause damage to the esophagus, stomach, intestines, or other organs along the digestive system.

This can lead to severe pain, bleeding, and even life-threatening conditions such as peritonitis.

Abscess formation

In some cases, when a needle gets lodged in the digestive tract, it can cause an abscess to form. An abscess is a pocket of pus that forms due to infection. The body’s immune system tries to isolate and contain the foreign object, resulting in a buildup of infected fluid.

This can cause symptoms such as localized pain, swelling, and fever.


Swallowing a needle can introduce bacteria into the digestive system, leading to infection. If the needle is contaminated with bacteria or other pathogens, it can cause an infection in the surrounding tissues or organs.

Symptoms of infection may include fever, redness, swelling, and increased pain at the site of perforation or puncture.

Blockage or obstruction

If a needle becomes stuck in the digestive tract, it can cause a blockage or obstruction. This can prevent the normal flow of food, fluids, and waste through the digestive system. A blockage can lead to symptoms such as severe abdominal pain, bloating, vomiting, and constipation.

In some cases, emergency medical intervention may be required to remove the obstruction.

It is important to note that swallowing a needle is a medical emergency and immediate medical attention should be sought. If you or someone you know has swallowed a needle, do not attempt to induce vomiting or try to remove the needle yourself.

Instead, call emergency services or go to the nearest hospital.

For more information on what to do in case of swallowing a foreign object, you can visit the Mayo Clinic or consult with a healthcare professional.

Factors That Affect Outcomes

When it comes to swallowing a needle, several factors can affect the potential outcomes. Understanding these factors is crucial in assessing the risks and determining the appropriate course of action. Here are some key factors to consider:

Size and shape of the needle

The size and shape of the needle play a significant role in determining the potential risks associated with swallowing it. Smaller needles, such as those used for sewing or embroidery, are generally less likely to cause severe complications compared to larger medical needles.

However, regardless of size, any swallowed needle should be taken seriously and evaluated by a medical professional.

Age and health status of the person

The age and overall health status of the person who swallowed the needle can also influence the potential outcomes. Children and older adults may be more vulnerable to complications due to their weaker immune systems and reduced ability to pass foreign objects through the digestive system.

Individuals with pre-existing health conditions, such as gastrointestinal disorders or compromised immune systems, may also be at a higher risk.

Presence of existing GI issues

If the person already has gastrointestinal (GI) issues, such as ulcers, strictures, or diverticula, swallowing a needle can pose additional risks. The needle may get lodged or cause injury to the already compromised GI tract, potentially leading to infections or other complications.

It is important for individuals with such conditions to seek immediate medical attention if they accidentally swallow a needle.

Other foreign bodies swallowed

In some cases, a needle may be swallowed along with other foreign objects, such as pins, coins, or small toys. The presence of multiple foreign bodies can increase the complexity of the situation and potentially affect the course of treatment.

It is essential to inform the medical professionals about all the swallowed objects to ensure appropriate diagnosis and management.

When to Seek Medical Care

Swallowing a needle is a serious matter that requires immediate medical attention. While it may not always cause immediate symptoms, it can lead to various complications if left untreated. If you or someone you know has swallowed a needle, here are some signs and symptoms that indicate the need for medical care:

Severe or persistent pain

If you experience severe or persistent pain in your throat, chest, or abdomen after swallowing a needle, it is crucial to seek medical care. The needle may have caused damage to your internal organs or tissues, leading to pain.

Ignoring the pain can worsen the situation and increase the risk of complications.

Fevers, chills, vomiting

Fevers, chills, and vomiting are potential signs of infection or inflammation caused by the needle. If you develop any of these symptoms after swallowing a needle, it is important to see a doctor. They will be able to assess the situation and provide appropriate treatment to prevent further complications.

Inability to pass stool

If you are unable to pass stool or experience difficulty in doing so after swallowing a needle, it may indicate an obstruction in your digestive system. This can be a serious complication that requires immediate medical attention.

Ignoring this symptom can lead to further complications such as bowel perforation or infection.

Signs of infection

Signs of infection around the area where the needle entered your body, such as redness, swelling, warmth, or discharge, should not be ignored. These symptoms indicate that the needle has caused an infection, which can spread and lead to more severe health issues if left untreated.

Seeking medical care promptly is crucial to prevent the infection from worsening.

Remember, swallowing a needle is not something to be taken lightly. It is always better to err on the side of caution and seek medical care, even if you are unsure whether the needle has caused any harm.

Timely medical intervention can help mitigate any potential complications and ensure your well-being.

Diagnosis and Treatment

When a person swallows a needle, it is important to seek medical attention immediately. The doctor will typically begin the diagnosis process by conducting a physical exam and asking about the individual’s medical history.

This will help the doctor determine the potential risks and complications associated with the swallowed needle.

Imaging tests like X-rays

In most cases, the doctor will recommend imaging tests, such as X-rays, to locate the exact position of the needle within the body. X-rays are a common diagnostic tool used to detect foreign objects, including needles, in the gastrointestinal tract.

These images provide valuable information to the medical team, helping them devise an appropriate treatment plan.


If the needle is not visible on X-rays or if further investigation is needed, the doctor may recommend an endoscopy. During an endoscopy, a flexible tube with a camera on the end (endoscope) is inserted into the digestive tract through the mouth or anus.

This allows the doctor to visualize the internal organs and locate the needle. In some cases, the doctor may use a specialized tool to remove the needle during the endoscopic procedure.

Surgery in rare cases

In rare cases where the needle is difficult to locate or remove using less invasive methods, surgery may be necessary. Surgery is typically considered a last resort and is reserved for complex cases or when there is a risk of serious complications.

The surgeon will make an incision in the abdomen or throat to access the gastrointestinal tract and safely remove the needle.

Antibiotics for infection

If there is evidence of infection or the risk of infection due to the presence of a swallowed needle, the doctor may prescribe antibiotics. Antibiotics help prevent or treat infections that may arise from the presence of a foreign object in the body.

It is important to take the prescribed antibiotics as directed and follow up with the doctor to monitor the progress of the treatment.

It is worth noting that the course of treatment for swallowing a needle may vary depending on the individual’s specific circumstances. It is crucial to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan.

Preventing Accidental Needle Ingestion

Careful handling and disposal of needles

One of the most important steps in preventing accidental needle ingestion is to handle and dispose of needles with utmost care. Needles should always be stored in a secure container, such as a sharps container, to prevent accidental punctures and exposure.

It is essential to dispose of used needles properly and not leave them lying around where they can be easily accessed by others. Many communities have needle disposal programs or drop-off locations where you can safely dispose of needles.

Keep out of reach of children

Children are naturally curious and may mistake needles for toys or other objects. To prevent accidental needle ingestion, it is crucial to keep needles out of reach of children. Store needles in a locked cabinet or drawer, or place them in high shelves that children cannot reach.

Additionally, it is important to educate children about the dangers of needles and emphasize that they should never touch or play with them.

Avoid laughing or talking with needles in mouth

While it may seem obvious, it is worth mentioning that one should never have needles in their mouth while talking or laughing. Accidentally swallowing a needle can lead to serious complications, including injury to the throat, stomach, or intestines.

It is best to remove needles from the mouth immediately after use and dispose of them properly.

For more information on needle safety and prevention of accidental needle ingestion, you can visit websites such as the Centers for Disease Control and Prevention (CDC) or the World Health Organization (WHO).


In most cases, swallowing a needle is not fatal or severely dangerous. With careful monitoring and medical care if any complications develop, the needle will safely pass through the digestive system. Avoid laughing or talking with needles in your mouth, and dispose of used needles properly to prevent accidental ingestion.

Seek prompt medical attention if you experience concerning symptoms after swallowing a needle.
